Hi guys, Yesterday, I noticed that the screen on my Lumia 520 was gradually dimming until the display backlight went completely off, even though the phone itself was still running. I tried restarting it, but that didn't help. I left it alone and went to sleep, and today it's working normally again with no issues so far. Does anyone have an idea what might be causing this? Could it be a hardware issue, or maybe some strange behavior related to increased humidity in the room?
