"iPhone 7 backlights not working 24hrs after screen repair" için yanıtI have a similar problem. I have more symptoms. My phone’s backlight intermittently doesn’t ‘wake up.’ It has the same symptoms but if I ‘reset all’, I have an 80% chance the backlight will turn on if it is dark or the auto brightness is turned off. It is almost always enters the no backlight mode when I shut off the backlight with it set to 100% brightness. The brighter the more likely the display will be out. The dimmer the more likely the phone will wake up with the display working. With auto I would use it all morning indoor with no problems. At lunch outdoors it would fail an not reset until I went in a dark place.
