[Lenovo Zuk Z2 Pro Questions & Answers] mixmaniax:
Dear community

I have an issue with my front camera on my Zuk Z2 Pro. I cannot switch to front camera only back camera works. There is no symbol for switching to the front camera beside the "shot" button in the camera app.

I tried to check the camera settings, but the as soon I try to navigate into the "Front camera photo" or "Front camera video" I just get a white screen with the title "camera" and nothing else.

I also installed other camera apps, but also no front camera access...

I have this issue since ever but I thought I'd better wait for Android 7 Nougat update, before asking you guys.

So this morning I updated phone from Stock ZUI 2.3.044 ST via OTA to ZUI v 2.5.335 - unfortunately the issues persists :(

Below you will also find crash log (I guess). Hope someone can help me out and has some idea how to solve this.

Thank you very much in advance for your help.
