To install a SIM card in Samsung Galaxy A3, you do not need to have specific skills and abilities. Therefore, everyone can cope with this task. The only thing you need to know is what format cards are suitable for the specified phone model and how the card holder opens in it. Let's consider how to independently insert a SIM card into the Samsung Galaxy A3.
What connectors does the Galaxy A3 come with?
To date, Samsung has released three modifications of the Galaxy A5. They differ from each other not only in the filling and screen size, but also in the placement and parameters of the SIM slots:
In Samsung Galaxy A3, the connectors are opened with a special key (ejector), which is supplied with the phone. However, if you do not have it with you, you can resort to a sewing needle or a simple paper clip.
SIM Crop Technology for Samsung Galaxy A3
If you decide to swap out your outdated smartphone for the new Galaxy A3, most likely you have a Mini or Micro SIM card. Therefore, before inserting an old SIM card, it will need to be cut to the Nano standard.
To give the card the required size, you can go to a phone sales point and perform the specified procedure there, paying a certain amount of money. However, pruning is quite realistic at home. This is done as follows:
After completing the preparatory work, the SIM card can be inserted into the phone.
Installing a SIM card in Samsung Galaxy A3
Installing the SIM card on the Galaxy A3 is done in the following order:
- Turn off the gadget and disconnect the power supply if it was charging at that time. Otherwise, the power amplifier or microcontroller responsible for power distribution may be damaged.
- Take the key clip, insert it into the round hole located on the cover of the card holder, and press lightly.
- When the tray comes out, pull it completely out of the phone. Do the same operation with the second slot (of course, if necessary).
- Insert a Nano-SIM, and if necessary, a second card or external microSD memory.
- Replace the connector by applying light pressure.
After completing the task, turn on the smartphone and check its performance. If the SIM card and memory card are detected, then everything is done correctly. If in the future you need to install a Nano-SIM in a Mini or Micro card holder, you can use special adapters sold in mobile shops. 
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 with a good set useful functions.
As with any smartphone, these two have several hidden functions 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 playing, and can also 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 is to 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 people prefer a button on the screen. Samsung has tried to accommodate the personal preferences of each and every one.
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 function, simply go to the Camera application, and from there to Settings (the gear on the right upper corner 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 the desktop.
The floating camera button can be activated in the settings Change the look of the interface
Some people (myself included) think that the TouchWiz interface is extremely ugly, which cannot be said about the "bare" Android. So now you know that appearance interface can be changed using different topics... And although this will not solve all the problems, at least it will make you more enjoyable to use your phone. You can also download wallpapers and icon packs.
The main drawback is the price. Are you ready to spend 120 rubles on a set of icons?
Fortunately, some themes / wallpapers / icons are available completely free of charge, and some of them look really good. You will find them in the settings under Wallpapers & Themes. You can also access this section by pressing the background of your screen for a few seconds, then click on the Wallpaper & Themes button that appears in the lower left corner of the display.
Use "protected" files
And while many loudly proclaim that they have nothing to hide, what can be found on their phone or elsewhere is a feature that allows you to hide certain things.
When you hand the 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 troubles, Samsung added an option to protect files, first it appeared on the Note 7. You can put everything you want to keep in a certain folder, and you can restrict access to this folder with a password or fingerprint.
The only condition for using this feature is that you have to use a Samsung code. Just go to the Applications menu, then in Samsung Apps and open Secure File. The rest is up to you.
Place your confidential information to a protected folder Receive notification reminders
Has it ever happened: you receive a message on WhatsApp during an important meeting, and after its end, half an hour later, you completely forgot to read the message?
Samsung has carefully thought out 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 the types of notifications, and also choose which app can send you reminders.
Go to the Access menu in the settings, and then to the Notification reminders section. Here you will also find other interesting functions such as the "magnifying glass".
It is very useful function for the forgetful Activate "simplified" mode
While advanced users will appreciate the customizable welcome screen, some of us lean towards simpler menus and larger font sizes.
You can activate 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 Simple Mode function and activate it.
Simple Mode lives up to its name Some of the tricks that are already on other smartphones from Samsung can be used on the 2017 A3 / A5 models.
Send SOS signal
You can send an SOS signal if you suddenly find yourself in trouble: go to Settings> Advanced> SOS signal, as soon as the option is activated, you can add a recipient. Now all you need to do to send the SOS signal is to press the power off key three times.
Split screen function
The A5 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 Google applications (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. New Galaxy A3 and A5 are no exception to the rule, so all you need to do is swipe right to access the Upday widget.
Don't panic in advance - if you're more used to Google Now, or just want to remove an extra widget from your home screen, Upday can be turned off.
To do this, you need to press and hold the screen for a couple of seconds. At the bottom, you will see three keys (Wallpaper, Widgets and Layout). Scroll right to access the screen located to the left of the center one. You will then be able to turn it off with the click of a button.
Fixing applications
In some cases, it can be convenient to lock the screen in one particular application. Notifications from all other apps will be blocked, you won't be able to open other apps, so your privacy will not become public.
Then press the multitasking key to see the list 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.
The picture on the left shows how to deactivate Upday; on the right - how to block the app screen from receiving notifications
