Can you reproduce this problem?
Take a photo.

I have another problem ..randomly the unit just reboot itself. No fix timing.

When I on Google map and reverse my car..the screen show this.

Используете ли какой-нибудь сторонний лаунчер, кроме стокового?
go to settings - system - Android settings - About device - PUSH on "system information" and show a screenshot the opened window with information.

Problem solved after latest update
