System UI has stopped

[Iggzor]

Yesterday i bought the XZ3. Since today im using the phone but now and then it freezes, resulting in a System UI has stopped working.

I experienced this while making a video call in whatsapp, while using the bokeh app and while using the camera app. Also one time with another app, but I cant remember which but it uses no camera.

Since all apps, but the last one, use the camera it is obvious that the camera is the problem. However i cant imagine Sony not testing such a main part of the Phone. I know the XZ3 has its child issues since it git releases yesterday, so i dont get angry, but Sony fix this problem.

Edit: i've update my system and apps. 

Thanks in advance

Indeed, i contacted my local support. They told me i indeed tried everything and i should come to the store. Then they look at it and maybe replace the Phone. I give an update tomorrow when im back.
