I created a bug report: https://fogbugz.unity3d.com/default.asp?1182900_prrh7uqrjsr4pnuu

If you have any more info, please share! :slight_smile:

Hey BrearJ,

Could you make a bug report and share the case number?

Thank you

Is this bug fixed?
We still meet this bug, most users use Samsung mobile, and all users in Android 8.
