[Q] Hardware key lights turn on when screen off
I've been using the stable version of CM 10.1.3 since Christmas and have experienced no issues whatsoever, it's worked flawlessly...until today. I woke up this morning to find my phone charging as I had left it, but the hardware lights were turned on. Thinking it was odd, I turned the screen on then off again and the lights turned back off as they should. When I came back after breakfast however, they were on again! This has been happening all day; I'd check my phone and find that the lights had turned on. I can't seem to find any pattern (like always 2 minutes after screen off) and it doesn't even happen all the time - I left it for half an hour and they didn't turn on, but the next time I turned off the screen they turned on again after a few minutes.
Has anyone else experienced this issue and, if so, how did you fix it? I haven't yet done a factory reset as I was hoping someone else would have a good fix that doesn't mean I have to reconfigure everything.
I've also noted signal dropping a lot today, but after turning the phone off and reinserting the SIM card it seems to be back for good (well, an hour at least). Could this be related?
Any help would be great
