How to open a Samsung Galaxy A 3. Useful tips for owners of Samsung Galaxy A3 and A5

Samsung has again released new versions of the A3 and A5 models - this is already becoming an annual event.

With the help of these devices, the company indicates its true intentions - to consolidate its position in the mid-price segment, presenting users with smartphones with good set useful functions.

Like any other smartphone, these two have several hidden functions worthy of your attention. Here are some of the most successful ones, in our opinion:

Add/Disable Game Launcher and Game Tools

Every mobile gamer knows what Game Launcher and Game Tools are for. These apps allow you to turn off notifications while you're playing, and they can also be used to take a screenshot of the game or even make a video. You can activate or deactivate them in just a couple of clicks.

All you need is to go to settings, find Additional functions and go to the “Games” menu. Here you will find the options you need.

Take photos with ease

On most smartphones, you can take photos by pressing the volume keys. Some people prefer a button on the screen. Samsung has tried to take into account everyone's personal preferences.

You can add a virtual key for your camera, this key can be placed anywhere on the screen when the viewfinder is on. Press this button and the photo is ready.

To activate access to this feature, simply go to the Camera application, and from there to Settings (the gear on the right top corner screen). Scroll down the menu and find the Floating Camera Button feature. Activate it and the button will appear in the Camera app.

We remind you: you can launch the camera by double-clicking the “Camera” button, you do not have to look for the camera icon on the desktop.

Change the appearance of the interface

Some people (including myself) find the TouchWiz interface to be extremely ugly, which is not the case with bare Android. So now you know that appearance The interface can be changed using different themes. And while this won't solve all your problems, it will at least make your phone more enjoyable to use. You can also download wallpapers and icon packs.

The main disadvantage is the price. Are you ready to spend 120 rubles on a set of icons?

Luckily, some themes/wallpapers/icons are available for free, and some of them look really good. You will find them in the settings under Wallpapers and Themes. You can also access this section by tapping on the background of your screen for a few seconds, then tap on the Wallpapers & Themes button that appears in the lower left corner of the display.

Use "protected" files

And while many people loudly claim that they have nothing to hide, what can be found on their phone or anywhere else, a feature that allows you to hide some things is useful.

When you hand your phone to your mom, you might not want her to see your party photos. Or maybe you don't want your girlfriend to see pictures of you dancing with other girls. Even if you haven't done anything wrong, making excuses is always unpleasant.

To avoid such hassles, Samsung has added a file protection option, first introduced on the Note 7. You can put anything you want to keep secret in a specific folder, and you can restrict access to that folder using a password or fingerprint.

The only condition for using this feature is that you have to use Samsung code. Just go to the Applications menu, then to Samsung apps and open Secure File. The rest is up to you.

Receive notification reminders

Has this ever happened: you receive a message on WhatsApp during an important meeting, and after it ends, half an hour later, you completely forget to read the message?

Samsung has thought through everything carefully and introduced a notification reminder feature: if you forget to read a notification, the phone will remind you about it.

Of course, you can choose the types of notifications, and you can also choose which application can send you reminders.

Go to the Access menu in Settings, and then to the Notification Reminders section. You will also find others here interesting features– for example, “magnifying glass”.

Activate "simplified" mode

While power users will definitely appreciate the customizable welcome screen, some of us gravitate toward simpler menus and larger fonts.

You can activate this feature in settings. But be careful - the icons will grow to huge sizes, even the notification menu will be changed!

To activate this mode, go to Settings and then select the Simple Mode feature and activate it.

Some tricks that are already available on other Samsung smartphones can also be used on the 2017 A3/A5 models.

Send an SOS signal

You can send an SOS if you find yourself in trouble: head to Settings>Advanced>SOS, once the option is activated you can add a recipient. Now all you need to do to send an SOS signal is to press the power key three times.

Split screen function

The A5 has a split screen feature. To get to it, tap on the multitasking symbol, but remember that not all apps are compatible with this mode. But applications from Google (Gmail, Play Store etc.) there are no problems with this mode.

Disable Upday

Samsung has decided to equip its devices with its own information system called Upday. New Galaxy The A3 and A5 are no exception to the rule, so all you have to do to access the Upday widget is swipe right.

Don't panic in advance - if you're more used to Google Now or just want to remove the extra widget from home screen, Upday can be disabled.

To do this, you need to press and hold on the screen for a couple of seconds. At the bottom you will see three keys (Wallpaper, Widgets and Arrangement). Scroll right to access the screen located to the left of the center. You can then turn it off with the click of a button.

Pinning applications

In some cases, it may be convenient to lock the screen in one specific application. Notifications from all other apps will be blocked and you won't be able to open other apps, so your private life won't be exposed to the public.

Then press the multitasking key to see the list running applications. At the top right of the most recent application you will find a “pin”. Click on it and the screen in this application will be locked.

Many devices running the Android OS are additionally equipped with a special environment - the engineering menu. With its help, the user has the opportunity to test all the sensors and modules of the mobile device, as well as adjust certain parameters of the gadget for more comfortable use. In Samsung phones, Engineering Mode is hidden in the system by default. And in different models logging into it is done differently. And the functionality of this area may also differ. Let's look at how to enter the engineering menu on the Samsung Galaxy A5, Galaxy S6, J3 and other smartphones from the Galaxy line.

Where to find the engineering menu on Samsung Galaxy

The main purpose of Engineering Mode is to fully test mobile devices at the final stage of their production. This environment was originally developed for debuggers on smartphones and tablets, but today anyone can use it. The main thing is to know how to open technical mode on Galax.

You can enter the engineering menu using a special combination (USSD code), which is written in the dial panel. However, these commands may differ in different phone models:

• in Samsung J7 and J1 the actual combination is *#*#0011#;
• for Samsung Galaxy A5, Galaxy S5, Galaxy S6, the dial *#*#8255#*#* or *#*#197328640#*#* is suitable;
• on Samsung Galaxy A3 the code is *#*#9646633#*#*;
• for Samsung Galaxy S3 – *#*#0#*#*;
• in Samsung Galaxy S7 Edge – *#*#8255#*#* or *#*#4636#*#*.

On other devices from the Galaxy line, you can use the service combinations *#*#4636#*#*, *#*#8255#*#* or *#*#3646633#*#*.

If you can’t open the engineering menu using the above commands, you can resort to one of the programs developed specifically for this purpose (EngineerMode, Mobileuncle Tools, Shortcut Master, etc.). To start the technical mode, just install and run one of the utilities. After this, you will automatically enter Engineering Mode.

All applications to open engineering menu work only with MTK processors (MT6573, MT6577, MT6589, etc.) and with some Exyon chips. For phones equipped with a Qualcomm CPU (for example, Samsung Galaxy A5), such software will be useless.

Main features of the engineering menu on Samsung Galaxy

Having figured out how to enter the engineering menu on Samsung, let's look at its main features. Full Engineering Mode for MTK chips equipped big amount tools with which you can make a complete diagnosis and fine tuning Samsung in many ways.

However, many smartphones have a stripped-down version of the technical mode, which somewhat reduces its functionality. And in mobile devices on the base Qualcomm processor through the engineering menu you can only view information about some modules and perform small tests of the main elements of the phone (display, modem, SIM cards and battery).

On the Samsung Galaxy A5 and Galaxy S6, the main sections of the engineering menu are:

1. Telephony;
2. Wireless interfaces (Connectivity);
3. Testing mode (Hardware Testing).

In the Telephony tab, the user has the opportunity to:

The Connectivity section is intended for diagnostics and configuration wireless modules Wi-Fi, Bluetooth and FM. It is not recommended to change anything here, as this may lead to failure of the smartphone.

The most popular tab in the engineering menu is Hardware Testing. This is where you can test the performance of the processor, battery, speakers, camera, display and GPS module. This area allows you to perform a complete diagnosis of Samsung during its purchase and identify possible malfunction products.
