Blue LED light doesn't turn off

I have had a 955(European, but I live in Canada) for about 3 months or so and just recently the phone's blue LED light turned on and just doesn't want to turn off. It is dimly lit but disappears briefly when I restart the phone. I have tried to reset the phone several times with no effect. When the light is off (for the few minutes after restart), LEDs pop up like normal (white for texts, green for calls). When the blue light turns on and stays on, no other LED shows up. I haven't made any changes to the phone in recent times. On a side note (I don't know if it's related), the phone has also been dropping calls several times per day as of late, sometimes upwards of 20 times per day. I changed the SIM card but that didn't do anything. The phone itself has also been acting a bit bizarrely, where random apps popped up without being opened, and call screen doesn't disappear even after pressing "end call." Any suggestions would be greatly appreciated as this is getting quite irritating.
