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 middle price segment by presenting smartphones to users with a good range of useful features.
As with any other smartphone, these two have several hidden features worthy of your attention. Here are some of the most successful, 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 play, and you can also use them to take a screenshot of the game or even take a video. You can activate or deactivate them with just a couple of clicks.
All you need to do is go to settings, find Additional functions and go to the "Games" menu. Here you will find the options you need.
Game Launcher is very easy to enable or disable Take photos with ease
On most smartphones, you can take photos by pressing the volume keys. Some prefer a button on the screen. Samsung I tried to take into account the personal preferences of everyone and everyone.
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 key and the photo is ready.
To activate access to this feature, simply go to the Camera app, and from there to Settings (gear in the upper right corner of the screen). Scroll down the menu and find the "Floating Camera Button" feature. Activate it and this button will appear in the Camera app.
Reminder: you can start the camera double tap the Camera button, you don't have to look for the camera icon on your desktop.
The "floating" camera button can be activated in the settings Change the appearance of the interface
Some people (myself included) think that the TouchWiz interface is extremely ugly, which cannot be said about the "naked" Android. So now you know what appearance interface can be changed using different themes. And although this will not solve all the problems, at least it will become more pleasant for you to use the phone. You can also download wallpapers and icon packs.
The main disadvantage is the price. 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 can find them in the settings under Wallpapers and themes. You can also access this section by holding down your screen background for a few seconds, then tap the Wallpapers and Themes button that appears in the lower left corner of the display.
Use "protected" files
And while many people vociferously say that they have nothing to hide, what can be found on their phone or elsewhere, a feature that allows you to hide some things, is useful.
When you hand your phone to your mom, you may 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 annoyances, Samsung has added a file protection option, which first appeared on the Note 7. You can put anything you want to keep secret in a certain folder, and you can restrict access to this folder with a password or fingerprint.
The only condition for using this feature will be that you will have to use a Samsung code. Just go to the Applications menu, then Samsung Applications and open Secure File. The rest is up to you.
Put your sensitive information in a secure folder Get notification reminders
Has it ever happened: you receive a WhatsApp message during an important meeting, and after it ended, half an hour later, you completely forgot to read the message?
Samsung has thought of everything carefully and introduced the notification reminder function: if you forget to read the notification, the phone will remind you of this.
Of course, you can choose notification types, as well as choose which application can send you reminders.
Go to the Access menu in Settings and then to the Notification Reminders section. Here you will also find others interesting features- for example, "magnifying glass".
This is very useful feature for the forgetful Activate the "simplified" mode
While advanced users will definitely appreciate the customizable welcome screen, some of us tend to use more simple menu and larger font.
You can enable this feature in the 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 Easy mode function and activate it.
Easy mode lives up to its name Some tricks that are already on other smartphones from Samsung can be used on the 2017 A3 / A5 models.
Send an SOS signal
You can send an SOS signal if you happen to be in trouble: head to Settings>Advanced>SOS signal, once the option is activated, you can add a recipient. Now all you need to send an SOS signal is to press the off key three times.
Screen split function
The A5 model has a split screen function. To get to it, click on the multitasking symbol, but remember that not all applications are compatible with this mode. But applications from Google (Gmail, Play Store, etc.) have no problems with this mode.
Disable Upday
Samsung has decided to equip its devices with its own information system called Upday. The new Galaxy A3 and A5 are no exception to the rule, so all you have to do to access the Upday widget is swipe to the right.
Do not panic in advance - if you are more accustomed to Google Now or just want to remove an extra widget from the 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 Location). Scroll to the right to access the screen located to the left of the center one. 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, you won't be able to open other apps, so your private life won't be made public.
Then press the multitasking key to see a list of running applications. At the top right of the most recent app, you'll find a pin. Click on it and the screen in this application will be locked.

Smartphone Samsung Galaxy A5 is a very popular gadget of the Korean manufacturer, featuring a large and bright touch screen. Unfortunately, this advantage is also a disadvantage - it is not difficult to damage the screen, despite the use of protective films. Many device owners are interested in how to replace display on samsung a5 on your own to save on workshop services, whether it is easy to do at home or not.
What is the screen of a modern smartphone Samsung Galaxy A5
This element of the gadget is a complex device consisting of several functional elements - an amoled display and touch screen. The first serves to display data, and the second - to be able to operate with this data. In all modern smartphones released after 2015, the display and touchscreen are interconnected by means of a special polymer adhesive and form a single module (OGS matrix).
At home, you can only change it as an assembly. You can separate the display from the touchscreen on specialized equipment with certain skills. Therefore, the only real independent option is to buy and install.
Screen replacement tools
To replace samsung display Galaxy A5 the following is required:
- A set of special screwdrivers (Phillips or Torx) for mobile phone repair.
- Pick, plastic card, or any other object with sharp edges.
- Hairdryer (a household hair dryer may work).
- Rubber suction cup equipped with a grip ring.
- Special adhesive type B-7000 or double-sided tape.
- Alcohol or glass cleaner based on it, soft wipes.
All this tool can be bought inexpensively in the GreenSpark online store.
Step-by-step process of replacing the display on the Samsung Galaxy A5
- We disassemble the phone. In this smartphone model, the body is made of metal, so the module is mounted in it with double-sided tape. To remove a damaged display, it is necessary to warm it around the perimeter with a hairdryer to soften the adhesive tape, and then pry it off with a mediator or a plastic card. Moving in a circle, carefully separate the module from the case. After we grab it with a suction cup, disconnect all the cables and pull it out of the case.
- Module installation. We clean the seat from the remnants of the old adhesive tape, attach the cables of the new screen with the sensor to the contacts and check the performance. If everything is fine, turn off the module, stick double-sided tape on the seat (you can use B-7000 type glue instead of tape) and install the display in place. Do not forget to connect the loops so that there are no troubles. In the case of glue, it simply presses the module well, gently remove the protruding drops with a napkin. If double-sided tape is used, we warm it up around the perimeter, as in the case when removing the display. After tightly, but carefully, so as not to damage, we press the module into the seat.
If you approach each of these operations responsibly, perform them carefully, realistically replace display on samsung galaxy a5 on their own. If you are far from this and do not understand electronics at all, it is better not to take risks and entrust the operation to professionals.
Third-party launchers are extremely popular among experienced users and there are several reasons for this.

- 4. Done.
After you have made your choice, you just need to confirm - click "Apply".
