Are you one of those who buy devices from Asian or Western countries and did not find the Arabic language in the lists?
The application enables you to reactivate the Arabic language on all Android devices that support this language.

If you do not have root on your phone, the permission to change the language on Android devices is protected in recent Android 4.2+ versions,

It is only granted for system applications,

If you are familiar with the ADB command for Android tools for programming, you can download Adb tools and connect your phone to the computer with the cable and then execute the following command to give the program the right to change the language,:

adb shell pm grant com.jkdevandroid.taaribelhatif android.permission.CHANGE_CONFIGURATION

You can search in Google for more details

If your device has root, the app can do a language change without having to activate this command.

Starting with Android 7, the program needs the right to write system settings,

For reference, some American and Chinese devices do not have support for the Arabic language so that it is permanently deleted, so the application remains valid only for applications that support the Arabic language, such as Google, Facebook and Twitter applications ...
