Sorry to hear about your disappointment. To help us know what happened, could you please provide some more details about your interaction with customer support?
I noticed the same thing - the phone only freezes after using camera. If I do not use camera, the phone works normally. Moreover, if I just open the camera app, but do not take a picture, the phone works normally. But if I take the picture, the phone freezes the same day. And it does not depend on the camera app - in-built or any other.
Hi guys ! I think I have solution for you. I had same problem and as you write that it only turn black if you take a photo so I realize that in the settings > Display there is item named "Press power button twice for camer" so I turn that off and Iam not getting any "black screens" anymore !! I hope that this helped someone :) (Iam sorry for my bad English its not my native language so dont hate me for that :D )
BTW: If you get that black screen you just press and hold VOLUME UP and POWER button for couple of seconds and the phone will reboot again :)
This trick does not seem to work, at least not for me. I turned off this "power button twice for camera" long ago, but the screen freezes still happen after taking pictures.
