I have a Samsung Galaxy J7. It's camera was destroyed by an accident. So everytime I open camera, snapchat etc apps it shows "Warning: Camera failed". For a reason I need my phone to take at least a black screen on snapchat by clicking on the button. Is it possible to edit the rom to make the camera take at least a black screen instead of showing "Camera failed" and how?
