Last night a bright white light appeared along the bottom of my screen. It has a greenish colour in the middle. It won't go away and it's really bright to the point where it hurts my eyes. It doesn't show up on screen shots, though. How can I get rid of it.
Are you still having this issue? If so, try a Soft Reset on the phone. This will end all processes and give the phone a fresh start. Press and hold the Volume Down and Power keys at the same time until the phone switches off and back on again.
