Back and home button stay lit
I've had my phone for about 3 months and it has always worked fine. Since Saturday, the lights for the home and back button have remained lit up even when the phone is locked. They aren't full brightness but just dimly lit but it has never done this before. I've tried to do a factory reset as I'm sure they are not meant to remain on but it hasn't done anything
Has anyone else experienced this or know how i can stop them being on when locked?
