Unity Android app will freeze on Samsung devices

We made a game with unity for android markets.

The game is running perfectly on Editor and all android devices except Samsung.

We have no issue with other brands. It’s just Samsung and it’s almost all the Samsung models. (new and old ones).
There is no error or crashes, it’s just the fps drop to 0 and the game will freeze.
We check the profiler, and there is no information about this issue.

We used DOTWeen and Spine in the game.
We don’t have any other libraries or tools.

Any help would be great.
Thanks a lot.

Have you tried turning off “Optimized frame pacing”? I have a similar problem, and this solution was proposed in several threads:
