When I open the camera app it gives an error like "unknown error" and the phone freezes then restarts itself, it only happens with the back camera, if i open an app like instagram and use the front camera with it there is no problem, please help, my dad gave me this phone because of that, he needed to take pics for his work and stuff like that and he couldn't fix it, he tried reseting the phone from the recovery thing, and other stuff but nothing helped.
