How to make the application supported on all phones?

Question

Unity

I made a game on Unity and uploaded it to Google play, as it turned out it can not be downloaded everywhere, one error is written "This application is not available for your device" I added all available devices to the Google Console.

Answer 1

If there is a device on which it is "not available" - then try installing the APK there directly from your computer via ADB - and you will receive a decryption of the error. For example, there may be a mismatch between the android version, the open-angle version, and so on.
If it is installed via ADB, but it is not downloaded from the market, then the problem is in setting up the market. For example, the account belongs to another country (yes, Google checks not by the current location, but by the account settings).
