Whenever I go to settings and to display, the brightness and the sleep buttons are faded out and I can't click them. I tried rebooting my phone and a factory reset but nothing works. I don't know what to do as I can't adjust my phone brightness or the sleep time. I'm using an Alcatel Pixi 3 (4.5) and it's running on KitKat 4.4.
Go to sitting then barrery manager and turn off that feature you should be able to adjust your brightness and time out features then it's that simple
