Hello, I happen to have an Xperia z1, since last night its screen went dark, as if he had dropped the brightness of the screen, at first I thought it had gone but then I realized I was going on because segupian calls and messages but the screen is always off super dark .............. that does not happen ...... perhaps the display fused??????
If the brightness is set to max and it still is very dark I suggest that you try to run a software reinstall using SUS.

If the problem still remains you should contact your local support team, to have the phone examined and fixed at an repair center.
