Black screen on device

I updated Unity from 5.5.0 to 5.5.2 and now when I install apk on device it shows black screen . What should I doo ?

Same issue here.
Any update?

In my case : sound is playing, also buttons are clickable, but nothing on screen. Whole black.

Use “adb logcat -s Unity” or this plugin to check if Android is giving any exceptions.
