Google began to block its applications on devices with unlicensed versions of Android. Changes were highlighted by the XDA Developers mobile community. When you try to install Google applications (for example, Gmail or “Google Maps”) on a smartphone or tablet with Android without a license, the user will be notified that the device is not certified by Google and further installation is not possible.
Google checks the version and build date of Android – if the OS modification was released after March 16, then applications from Google will not work. The user can independently add his device to the white list by registering the Android identifier on Google. The company has set a limit for each user: you can register no more than 100 devices with a modified version of Android. The 9to5Google edition warns that every time you reset the device to the factory settings, the identifier changes, that is, each new identifier will be counted as a separate device.
The Android Open Source Project platform is open and free for all manufacturers, provided that their devices are certified by Google. A smartphone or tablet with an Android modification must meet security and compatibility requirements. Most devices with their own build of Android without a Google certificate are released by Chinese smartphone makers, says Ars Technica. In addition, Amazon’s Kindle Fire e-books work without a certificate.
