[5.3.0]Occasionally freeze on Android devices

Hi all,

I’m testing my game demo in android devices. The game occasionally freezes during gameplay, without leaving any error in logcat. It’s like a deadlock, the game does not quit, it just pauses without accepting any user input, and the music is played further. It only happens in some type of android devices.

I tried to use Unity Profiler to check the CPU usage. Interestingly as soon as the freeze comes the Profiler stops recording and switches back to “Editor” as “Active Profiler”.

We are right now on Unity 5.3.0f4 32bit.

Any hints how to analyse such freeze?

I finally found uGUI animation caused freeze. Maybe it’s a bug in uGUI.
