Problem shadows Android

Hi everyone! I’m trying to create a mobile game for Android, but I have a problem with shadows.
In the Unity editor there aren’t problems with them, but when I tried to install the APK on some devices, I had a problem, but on only one device (Samsung S6 Edge).

This is the result on Samsung S6 Edge. I tried to disable shadows and the problem disappears, but I want shadows and I don’t know how to fix this problem.
On others devices there aren’t problems with them.

In your lights shadow settings, increase the bias, try 2.
