BTW, neither of the apps that use camera functionality work, and they all give me an error-message to the effect that I'll have to grant the app camera-access. At the moment the only other app to access the camera on my phone is UTorch.

@AppLee said in Camera app doesn't work:

In my case, the reboot worked with my Nexus5, the problem occurred few times.
Have you tried to remove the cache files before rebooting?

Thanks for your reply! I just tried that and removed all 111 files from the cache and rebooted, but the camera app still won't work. What is strange is that each time after I try there are 111 files in the cache again.

I'm not sure if this might be related: The Camera app on my BQ Aquaris 4.5 stopped working around the 1st of March, I think it was shortly before OTA 8. Whenever I start the camera app I get either the camera app's interface with a black background, or more usually, a message telling me "Camera app doesn't have permission to access the camera hardware or another error occurred. If granting permission does not resolve this problem, reboot your device".

Of course the Camera app has permission as per the system settings, and rebooting doesn't solve the issue.

I've been wondering if the problem was the same as with the MEIZU Pro, or whether the camera was simply broken.
