Blue screen after building with unity on some android devices, how to fix it?

Question

Unity

Yes, there was already such a question, but the problem is that on some devices the game works, and on some it does not. To be more precise: on my tablet with a resolution of 2560x1920 it works - you can see the picture and hear the sounds, but on the smartphone 800x480 there is a blue screen and you can only hear the soundtrack, and even surprisingly, the game reacts to touch and shows ads. What is the problem?
