Back Facing camera not working? topic

Hi, my back facing camera does not work suddenly.
The only camera working is the front facing camera. there is no option to turn the camera around to use the back facing one. I have tried other apps but there are no options to do so.

[Q] Screen shuts off automatically when taking selfie facing down topic

I have no idea why but I seem to have problems on my Z3 nobody else has, it's weird. But anyway. This happens everytime and it does happen whenever the front facing camera starts, regardless of the app including the stock camera app. Whenever I try to take pictures with the front-facing camera in bed (with my phone facing down) the screen shuts itself a few seconds after the camera starts.

My phone is totally stock, has Apex Launcher installed. I don't know if that'll help find out the issue. Thank you for helping this noob. :(

Dust under front facing camera topic

So my note 4 has magically attracted dust under the camera. It's quite obvious and annoying. A big black spot.
Any suggestions? I tried opening it but way to much work.
