in Google Play Console writes such a failure in ANR ошибках , I can not understand the reason and how to fix it.

Who faced such a problem and decided to write it please how did you manage it.

This problem is on 30 devices, they all have Android 4.

  • Do you have any plugins? Perhaps they are trying to use some function from later versions. In the debug not catch what exactly this class is requesting? Unity itself has a minimum supported version 4.1 - M. Green
  • In debugging it will not work because I do not have a device with android 4. The project is set to 4.1 and higher. We removed all services, namely their initialization, i.e. libraries remain, but nothing causes them and does not twitch - GR1995
