I've just upgraded my Galaxy S3 to 4.4.2 and I'm having big issues. First of all, when I just turn my phone on, the ringtone starts playing accidentally (VZWAirwaves.ogg) and I can't stop it. Also, when I plug my phone to the charger, another ringtone starts playing (so two of them at the same time) and the only way to get rid of it is to put the phone on a silent mode. Also, the phone now always stays turned on and I can't lock it.
I rooted it and deleted VZWAirwaves.ogg file in /system/media/ringtones but the ringtone still plays after turning my phone on.
I would really appreciate your help because I think my phone is possessed by the devil.
