The smartphone does not boot. The phone does not turn on

The telephone - despite the constantly evolving information system, these small funds for telephone communication continue to be at the peak of their popularity. Thousands of residents have no idea how their life would change, in what direction it turned, if they did not have this small, but indispensable assistant like a phone or smart phone. Many will agree that this is not even a communication device, but an extension of the hand, whose malfunction can cause serious discomfort. Many people cannot afford to be without a phone even for a minute. And suddenly this very second will arrive on the device important message or a call, which will radically change the course of events in the life of the owner of the phone. And extreme panic can begin the second when the smartphone owner realizes that some problems are occurring in the device. Well, if the music file does not open, or the pictures on the phone have become more vague and inaccurate. But if the phone turned off, and then does not turn on at all? What to do in such a situation? Start ringing the bells and include all your friends who may have also experienced such a situation, or find an experienced specialist who can correctly understand the “whims” of the phone and return its owner to the usual rhythm of life as quickly as possible. After all, some people have absolutely no idea how you can sleep, watch TV, go to an important meeting without such a faithful and already integral to the human nature of the phone. It’s good if the phone has faithfully served its owner for many years and he can afford to “be capricious”, but if a failure occurred in a brand new smartphone, then the nerves and calmness of the smartphone owner are in big question.

Don't hurt yourself!
The first thing to do if the phone turns off and does not turn back on is not to panic. At such moments, it is likely that actions will be taken that will further aggravate the situation.
What do almost everyone who does not turn on the smartphone? Everyone opens the cover of the phone and begins to look and find out what is happening with the phone? What part could fail? And to clarify these issues, everyone starts pulling wires and nuts. You should not do this if you want to leave even the slightest chance of restoring your phone. The fact is that a person who is not familiar with the secrets of a smartphone device is unlikely to be able to independently find the cause of the breakdown. It may be some small thing, but excessive curiosity quickly transforms a small cause into a larger nuisance. Who knows, maybe the only reason is that the battery is suddenly discharged and the device itself needs to be simply put on charge. Experts identify a number of reasons that can lead to such a problem as not turning on the phone. We'll talk about this.
1. Check the battery.
Just a couple of minutes ago, the phone worked correctly, and nothing foreshadowed the onset of trouble, this is how those smartphone owners who have already encountered this problem can characterize the situation.
The charger on the phone showed an almost full battery, you could forget about recharging the device for the whole day. However, it is worth considering the fact that modern mobile devices, equipped with Wi-Fi or Bluetooth options can consume many times more energy. The thing is that the phone is in constant search new available network, which would allow the host to access the Internet. This takes a lot of battery power. Of course, these functions are indispensable for a modern user, but you can turn them off and turn them on only when this service is needed. Otherwise, the phone's battery drains in seconds, and is completely unmanipulable that would allow the phone to turn on again. In this situation, the only thing that can fix the problem is to put the phone on charge! In some cases, it will take the battery only half an hour to be able to return working condition phone, and some smartphones charge for about a day and only then turn on again. It all depends on the condition of the battery itself.
2. Check Charger!
If the smartphone did not turn on again, even after being charged for more than a day, then in this case it is necessary to inspect the charger itself. Who knows, maybe some wire has disconnected in it, or some contact has come off? The problem may also lie in the phone jack. After all, in modern devices has only one hole, which performs many functions - charging, headphones, connecting to a computer, and more. The only way to check the performance of the charger is to charge the phone with a frog battery. If the phone starts working fine, ask for a new charger.
Other people's chargers can also lead to a breakdown of the phone. Many cases have been identified when expensive mobile devices became unusable due to contact with foreign chargers that were not suitable for their type. This can lead to a more severe problem, which can only be fixed by flashing the smartphone.
3. Button on / off.
Another reason that can explain the reason for not turning on the phone is a malfunction of the button responsible for turning the mobile device on and off. There could be many reasons for this. In the case of a new device, the entire responsibility lies with the manufacturing company, which could make a mistake and a defect was formed during production, which led to the incapacity of the button. The owner should contact the store where he purchased his device directly. There he can be offered new phone or suggest contacting service center where they will try to find out the cause of the breakdown and try to eliminate it.
In the case of an older model, when you can be more calm about the state of the buttons, such unpleasant incidents can also happen. Only very often it happens that if one button fails, then the entire keyboard may not work. A number of cases can lead to this, the phone has fallen, which caused the keyboard to shift, or moisture has got into the device, which has a more detrimental effect on the device. Regardless of the reason, you need to contact a specialist who will be able to identify the cause of the incapacity of the button. Perhaps in the future you will be offered several options for action:
replace the keyboard panel;
perform a complete cleaning of the mobile device;
partially or completely replace the keyboard controller.
The reason for the non-working state of the phone can be even the most ordinary flash drive. In many cases, mobile devices are released without a memory card and the buyer must buy additional memory for his device. Often the selected model and manufacturer is incompatible with the telephone device. You need to buy flash drives only in trusted stores that sell original products from reputable manufacturers. It is also necessary to check the compatibility of these two systems back in the store. Put the flash drive in your phone and try to turn it on. If the phone immediately began to freeze or does not see the device itself at all, then you can safely return the selected flash drive to the seller. If the smartphone refuses to work with any kind of flash drives, even with minimal memory, then you will have to contact the service, where they will flash the device.
4. Install updates.
Who doesn't love downloading new updates to their phone? Especially if you have full access to the Internet, and there certainly is something interesting to download to your device. But not all updates can benefit the smartphone, some updates are incompatible with the features of the system. mobile phone, which leads to device failures. If this is the case, then the phone immediately starts to give signals that the new application is not in contact with the phone. The device just starts to "fail". Inscriptions are periodically displayed on the monitor, the phone can turn on and off on its own. What should be done in this situation? Turn off the phone, remove the battery, wait a couple of minutes, then turn it back on and quickly delete new apps and settings that have been made recently. Even if you did everything right, it will take time for the device to return to its previous performance.
If the phone does not recover, then you will have to take more serious measures to strip the phone - a function that removes all settings on the phone and returns it to its previous factory settings. This function does not affect the contents of the SIM and memory card, everything else is updated.
5. The cause of the malfunction may be mechanical damage.
When presenting a new smartphone model, each manufacturer praises their products, but modern phones should not be called invulnerable either. Often, many people put the phone in the back pocket of their jeans. It is worth unsuccessfully bending over or sitting down, the phone will fall and may break. It’s good if the phone just doesn’t turn on yet, but this can still cause a lot of trouble that you will have to contact the service center.
At first glance, smartphone owners do not find any damage in the device and cannot themselves explain why their phone failed. Maybe you lent a phone to someone and dropped it and didn't tell you? Anything happens. It may even be that the co-owner of the phone did not notice how he sat down and damaged his smartphone.
First you need to restart the phone, remove the battery, put it back in place and try to turn on the phone. If these measures do not lead to the desired result, the phone does not turn on, then you need to urgently contact a specialist, perhaps the contact has gone and the phone can be easily repaired. In many cases, the service center offers to flash the phone, arguing that this the only way restore the phone. In some cases, this is true. You should not be afraid of flashing, the device will work as before, it may even be better.

I am sure that among the readers there will definitely be those who have encountered such a problem - the phone turned off at one fine moment and does not turn on anymore. Or those whose mobile phone periodically turns off spontaneously. And for the lucky ones who have not encountered such troubles, it will be useful to know what to do in such cases.

Let's take a look possible reasons such malfunctions, using the following situations as an example:

Situation #1

In the evening, when you came home, you put the phone on charge, and in the morning you removed the phone that did not turn on from the cable. You are in shock. You take the battery out of it, insert it back - nothing changes. There is no reaction to the charger. What is the reason?

1. Before you panic, check if your charge has burned out. To do this, take any other phone and make sure that the charge is on. If not, then you're in luck - just use a working charger. A similar problem can be with the cable.

2. If everything is OK with charging, then it also gets upset early - the option of the so-called "deeply sat down battery" remains.

What it is? Normally, the battery charge level ranges from 3.6 to 4.2 volts. Moreover, the manufacturer calibrates the device in such a way that a battery voltage of 3.6 volts corresponds to 0% charge indication, and 4.2 volts, in turn, to 100%. When the phone is properly calibrated, when the minimum battery level is reached, the power controller will turn off the phone, and when you press the power button, a full battery indicator will be displayed. If you put the phone "up to the stop", and then, after a full discharge, start the device several times, "distorting" the battery, the phone may be discharged below the permissible minimum (3.6 volts). And a conventional charger will not be able to charge it in this state.

At home, solving the problem of a "deeply dead battery" is problematic, but possible. To do this, remove the battery of the phone, connect the charger and, holding the power button, insert the battery. If the phone's screen lights up and the charge starts, you're in luck. If not, you will have to seek help from a specialist who will charge the battery on a special power supply. Even the smallest workshop should have such equipment, and even the most inexperienced craftsmen are familiar with the "battery start" procedure.

3. Another reason for “unplugging” without a reaction to the charger may be a broken phone jack. In this case, the device starts after the battery is charged, for example in a service, but after a complete discharge it cannot be charged and turned on again. Breakdowns like this usually develop gradually. Most likely, the phone already had problems with charging, but they were successfully solved by a cunningly connected cable (upside down, stretched with a clothespin, etc.) But at one "perfect" moment, all your know-how stops working and the charging socket simply breaks off fees.

Unfortunately, it is very difficult to solve such an issue at home, and most likely you will have to contact the service. It is important to understand here that if you have been torturing yourself and your phone with all sorts of “devices” for a long time, then it is quite possible that the broken socket has already done trouble on the board (for example, it tore off the elements adjacent to it). So do not delay with such a breakdown.

And further. If you have already returned the phone to the service, be sure to demand that after the repair you return the replaced part. Many "masters" are too lazy to change the charging socket, but simply solder the old one. Which doesn't fix the problem at all. They eliminate only the consequence - a torn socket, but forget about the root cause - poor contact of this very socket with the charger.

Situation #2

Your phone was fully charged, you were using it and it went out right before your eyes. The reasons may be the following:

1. The problem may be trite dead battery. When you use your phone, dust gets into the battery compartment. Small particles of this very dust fall asleep between the contacts of the battery and the contact block of the phone, creating a dielectric coating during the friction process. At one fine moment, its amount can reach its critical minimum and the power simply stops flowing to your phone.

In this case, to turn on the phone, you need to remove and reinsert the battery. If it helps, take a stationery eraser and gently - so as not to damage the contacts - wipe it contact groups phone and battery. It is strictly forbidden to use vodka, cologne or even medical alcohol for cleaning, because even pure medical alcohol contains 4% water.

If the manipulations performed did not give the expected result, then it is worth checking how tightly the battery sits in the battery compartment. If there is play, press the battery with a piece of cardboard so that it is in close contact with the terminal block.

2. Followed by power button not working. Let's say you talked on the phone, ended the call, locked the screen with the power button, but you could no longer unlock it. Visually, you see a phone that does not turn on, which does not respond to the power button. You distort the battery, try to start again - zero reaction. You make a control call to a phone that you previously disconnected and the call goes nowhere.

How to find out that your power button is broken and understand the cause of its malfunction? This problem is determined by setting the phone to charge. If the charging indication appears, and the phone still does not respond to your efforts to start it, then with a high degree of probability the button died. The main causes of such breakdowns are mechanical damage, moisture ingress, natural wear and, of course, a factory defect.

Unfortunately, fixing the power button at home is extremely difficult. Most likely you will have to resort to the help of specialists.

3. Proximity sensor. This sensor is triggered during a conversation when you put the phone to your ear, blocking the screen from accidental clicks. In the event of a breakdown after making a call, the screen goes blank and does not light up even after you remove the phone from your ear. The phone continues to think that you are talking on it. If you do not pay attention to the fact that the voice of your interlocutor is still coming from the speaker, it may seem that the phone is frozen or turned off. Such a breakdown often occurs after an unsuccessful repair. touch screen in non-specialized SCs or after the fall of the phone.

To make sure that this particular sensor is out of order, just wait until the “other end of the wire” hangs up. If, after the end of the conversation, the display lights up again, it means that your phone has been diagnosed.

Repair of the proximity sensor is possible only in the service center.

4. "Broken software". Probably the most common phone breakdown. Well, if not the most common, then definitely the most beloved. Remember the notorious: "buggy - you need to reflash", which, I'm sure, you yourself have used more than once.

Unfortunately, phone firmware is not a panacea. Especially if the device does not turn on. But when is it worth taking up the rewiring?

  • if the smartphone freezes during use, and after “juggling” the battery does not respond to the power button
  • phone won't boot past splash screen
  • the phone reboots cyclically, reaching the same place during the startup process

In the event of a software failure, all of these symptoms are permanent. If the phone sometimes starts, sometimes not, you need to think about a severe hardware failure.

5.Phone hardware failure caused by the failure of electronic components. Of course, the diagnosis of such malfunctions should be carried out in a service environment.

Situation #3

The most unpleasant cases are when you yourself caused the device to break down.

1. Phone drowned or flooded. In such a situation, the immediate intervention of a qualified specialist is required. The only way you can be useful is to turn off the power to the device as quickly as possible, do not try to turn it on and, moreover, charge it. Know that even a well-dried phone at home runs the risk of becoming a “key fob” if you give it power. I think not everyone has isopropyl alcohol at home, ultrasonic bath, soldering station and binocular microscope, so entrust such repairs to professionals.

What measures can be taken if the phone drowned far from civilization, I will tell in the next article - "What to do if I drowned my phone."

2. You dropped the phone and it stopped turning on. This is due to mechanical damage to the soldering, rupture of surface tracks, or, even worse, an interlayer defect in the motherboard. Along with moisture, such breakdowns are classified as complex and it is impossible to fix them at home.

When your phone does not turn on, there is no benefit from it, you understand. But why does he refuse to work? Let's try to consider the most common cases and solutions on how to be and what to do if the smartphone does not turn on.

The same situation can have very different roots. In some cases, you will get off with a few minutes spent, in others you cannot do without contacting specialists. But in any case, it is better to be prepared and know everything possible in advance.

Possible causes and solutions

Let's try to consider some cases. Sometimes the problem can be eliminated by simply looking at it more carefully. And if you still have to contact the workshop, you will know what to prepare for.

The battery is dead or defective

One of the first reasons why a smartphone does not turn on is battery drain. It doesn't take long for modern phones (especially powerful flagships) to use up a full charge; some of them, with active work, sit down in a matter of hours. And if you accidentally left a resource-intensive game or a flashlight utility on, then this is generally a nightmare! You may not expect the battery to run out so quickly.

First, try charging your phone. If it charges and turns on (not immediately, after a few minutes) - the problem is solved.

If not, but the battery in it is replaceable - do not be too lazy to go to the store and try the same with another battery. If the problem is solved in this way, then you will not have to go far for a replacement.

Worst of all, if the case is non-separable. Then you cannot avoid going to a service center or a workshop.

Charger

Frankly speaking, one of the simplest cases. If your mobile phone, having completely discharged, cannot turn on again - maybe it just does not charge?

Just test it with another charger. If charging starts, then, obviously, the matter is in the charger. You can also check the problem charger in parts - a separate adapter and a separate USB cable to replace the non-working component.

power button

The power button is perhaps the most commonly used on the phone. And for the same reason - the most vulnerable. It can be damaged if your "patient" falls successfully - on a button or a corresponding board, or simply from heavy use.

It's good if your phone has alternative ways unlocking (for example, tapping on the display or pressing the Home button), but, alas, they are not suitable for turning on a turned off device.

Check that with the button, it will turn out only in the conditions of a repair shop.

However, there are ways that can help you at home:


However, all these methods are just a straw for a drowning man. There is a high chance that none of them will help. Then your road is straight to the workshop.

Socket not working

This reason is rather anecdotal, but it also takes place. So if your mobile gadget is discharged and does not want to turn on even when connected to an outlet, try connecting it to another outlet that is known to be working. Perhaps, in fact, you do not need to carry your mobile to the workshop, but call an electrician to your house.

Visible: Samsung Galaxy won't turn on

Problems with the charging connector

In the era Micro USB Of course, bringing the connector to full wear is problematic. However, this happens, especially if you use cables from other manufacturers.

So, for example, manufacturers of advanced cases often complete their gadgets with a cable with an extended plug, which can be used to charge the device without removing the case. But attempts to fully insert such a plug directly into the connector can end in failure.

In this case, you need to try whether the gadget is charging from other chargers (and yes, from other outlets!) If so, then we can assume that you got off lightly. If not, then you will have to change the connector in the workshop. Fortunately, replacing the connector is not the most difficult technical task.

Software failure

On the forums of Android connoisseurs, terms like "brick" or "bootlap" are often found. They do not mean anything good: “brick” is an Android device that flatly refuses to boot after firmware, and “bootlap” is a constant cyclic reboot.

Why does this occur?

  • the firmware process was interrupted. For example, by negligence, a child, a cat, or you yourself pulled the cable out of the socket. Or your electricity was cut off; that is why it is better to use laptops with a fully charged battery for flashing.
  • you tried to install firmware from another model on your phone. Sometimes the same model is produced for different regions in different modifications, which also affects the software.
  • you did not carefully follow the instructions that are necessarily attached to each software update.

What to do? Each model has its own recovery procedure. Since you undertook to flash Android yourself, it means that you have elementary ideas about the basics.

As a rule, to restore devices in a bootloop, you need to either clear all data or upload it to a memory card correct version firmware and install it via recovery menu. How to enter this menu depends on specific model your "patient".

"Bricks" are usually restored through a computer. For models based on different chipsets, there are separate recovery utilities. Unfortunately, this is too broad a topic to cover in one article.

Update error

Upgrading your OS is now easier than ever. In most cases, it comes "over the air": you do not need to download the firmware image to your computer and connect with a cord. The image is downloaded directly to the device memory and installed from it.

But sometimes there are process errors. For example, if there was not enough memory to unpack the archive. Or if the battery died right in the middle of installing an update.

As a rule, in the mechanism OTA updates there are protective measures and ways to recover. But if they do not work, you will have to install the firmware in the old way, through a computer. How? - look for details specific to your model. Or again, contact the experts.

Mechanical problems

Modern smartphones are quite fragile technology. Even models with protection, which are pretty good at resisting scratches and abrasions, can be hit so that they suffer. What to say about the fragile budget buildings and displays without protective glass!

Usually, if the device does not turn on due to a fall, the cause of the problem is visible to the naked eye. The display could have survived, but the lid could fly off, cracks and dents could remain on the case. This is enough to damage the electronics.

The following options are possible:

  • communication between batteries and system board. Then the smartphone turns off immediately;
  • communication between the battery and the power controller is broken. In this case, the device will "die" after the battery is discharged and will not respond to an attempt to charge it;
  • the battery is damaged. Various manifestations of the problem are possible;
  • suffered motherboard. Perhaps the saddest of the situations. The problem can manifest itself immediately, and some time after the fall.

In any case, if your smartphone has started to junk even a little after a fall, bring it in for repair.

What to do if the smartphone fell into the water and does not turn on

It's hard to imagine your phone falling into water and getting wet without your knowledge. So, you managed to swim with him through the lake without noticing the swimming shorts in your pocket. Or dropped into a deep puddle, so deep that it took a while to find it. In general, the newly found device does not turn on, no matter what buttons you press.

Exist general instructions on dealing with "drowned":


Maybe this procedure will not save. But at least you will know the cause of the problem when you go to the repair shop. Tell it like it is.

There is no need to hope that the case will be regarded as a guarantee, to hide your awkwardness or be ashamed of the trouble that happened to you. This will not increase the cost of repairs, and specialists will be able to quickly find the affected components.

Of course, a faulty smartphone can be taken in for repair immediately, without trying to fix it yourself. But sometimes the cause of problems is ridiculously simple, and you just need to understand it in order to fix it.

Some other cases require some action on your part (especially software failures), but by delving into the problem, you can avoid spending money and wasting time. We hope this material has helped you in the fight against malfunctions.

Method 1: Factory Reset via Recovery

Let's say you updated the firmware, then rebooted the device, and it freezes at the boot stage. 10-20 minutes have passed, but nothing has changed. Probably, there was a system failure and one of the methods to solve the problem is to reset the data. It's easy to do this:

  1. Go to Recovery Mod. To do this, hold down the volume down button and the power button.
  2. Then you need to use the volume up key to select Wipe data factory and press the mute button.

  3. Then select to restart the device.

  4. If Recovery is not installed correctly on your device or it is not there at all, you should visit the w3bsit3-dns.com forum, find your phone model there and find out what to do.

    Method 2: Flashing


    If the previous method turned out to be useless and the system does not boot to the end again, you should reflash the smartphone. If to speak in simple words, it means to reinstall the Android system of the device. This is done either through a modified Recovery, or through special program Flash Tool or Odin (for Samsung). Yet again, detailed instructions The firmware of your device can be found on w3bsit3-dns.com.

    Before flashing, be sure to charge the device, at least up to 50%. Install only official firmware. If during this process something goes wrong, the device may stop turning on altogether.

    Method 3: Remove the SD card


    Why does my phone turn on but won't boot up? Did the previous solution not help? Rarely, the reason for this is the incompatibility of the memory card with the device. In this case, you need to try to remove it and turn on the device without it.

    Method 4: Service Center


    If nothing helped, the phone does not boot to the end, what should I do? It's most likely a hardware failure. You need to go to the service center and hand over the smartphone for diagnostics. Specialists will identify what the problem is and fix the device.

    How to save information from the internal memory of the phone

    What to do with the SD card of the device is clear, it can be pulled out, connected to a PC and removed required files. And what about the memory of a smartphone? If you were not lazy and did backups, then there must be a backup file on the memory card. Still can save google sync. If it was enabled, then your photos, videos, contacts will be stored on the cloud. In other cases, alas, the data cannot be saved.

    Conclusion

    Now you know what to do if your Android device turns on, but does not fully boot up and freezes on the splash screen. Use one of the methods we described, it should help.

What to do if the phone does not turn on? Agree, for any modern person this is a real disaster. It is important to stop panicking - on emotions you can do much worse and break your favorite gadget completely. It is better to think, find out what the cause of the breakdown is, and then proceed based on this information.

Step 1: Check the battery level

Even if, according to your calculations, the charge level was high a few hours ago, and your phone should have been working for at least a day, the reason may lie in the fact that as a result of too much load, the phone is completely discharged. This is especially true when it comes to new smartphones. Their functionality today has reached such a level that they have actually become real mini-computers. But this does not have the best effect on the duration of the device: for example, always-on Bluetooth or Wi-Fi “kills” the battery very quickly, because the phone is constantly looking for a connection to inform the owner about it. Therefore, do not forget to disable these options or train yourself to use them only as needed.

What to do if the phone does not turn on for this reason? To begin with, make sure that you are not mistaken: turning on the gadget, you will most likely see how the screen “comes to life” for a moment, and then immediately turns off again and will no longer respond to any of your actions. It is also worth mentioning that you may need to buy a new battery: on average, the battery life does not exceed 2-2.5 years, after which you will have to replace it.

Step 2: Check your charger

So, your phone does not turn on. You put it on charge, thinking that the battery just sat down, but several minutes, half an hour, an hour pass, and your device still does not show any signs of life. We advise you to carefully inspect the charger itself. There is always a possibility that the contact is coming off or the wire is damaged. Also, the root of the problem may lie in the socket of the smartphone itself - it can easily break or become unusable due to too frequent use. Especially considering that in modern smartphones for all functions (charging, connecting to a PC, listening to music through headphones, etc.) the same connector is used. How to check it? First of all, try to find a universal frog battery and try to charge the battery. If the phone starts working normally, you can safely go to the store and buy a new charger.

In some cases, you can see this picture: the phone is already connected to the network, but the charging indicator continues to flash. Experts say that there may be two reasons for this. The first one is severe overheating, as a result of which the battery simply does not receive energy. The second is the use of a "foreign" device to recharge the gadget, especially when it comes to cheap low-quality models.

Step 3: Check the on and off button

There is another reason. If you just bought new equipment and did not use it, the fault lies 100% with the manufacturer - most likely, you are faced with a factory defect. In addition, this situation can happen if you drop the phone or accidentally spill water on it. What to do if the phone does not turn on for this reason? Depending on the situation, the master in the service center can completely replace either the keyboard controller, restore the mounting soldering, or carry out a complete cleaning of the device and eliminate moisture that has got inside. Unfortunately, one cannot do without the help of a specialist in this matter. And as practice shows, in 20% of all cases of contacting service centers, the problem lies precisely in the “on / off” button.

Step 4. Beware of software failures!

Finally, consider what to do if the phone does not turn on after installing updates or flashing. Here, most likely, you are dealing with failures. software and system damage. In some cases, it’s enough just to wait: “realizing” that something went wrong, the device will reset itself and return to normal, working condition. If this does not happen, you still have to carry it to a service center so that the master can find out the exact cause of the breakdown and fix it.

And remember: the most important thing is not to panic, even if the phone does not turn on. What to do, you already know. So, do not get confused in a difficult situation. 95% of problems can be fixed in the nearest service center in less than a day, and the cost of repairs will not be too high, so your favorite gadget will soon return to you safe and sound and will continue to serve faithfully.
