I have already spoken with tech support via phone earlier this evening, and they couldn't resolve...
A couple of days ago I heard my phone ringtone sounding, and nobody was calling. It kept ringing and I finally had to mute the sound. This seems to happen when I power the phone back on. Earlier tonight when I called tech support about this, we discovered quite by accident that my Gallery app has disappeared from the Apps list. We were at that point where we were going to do a factory reset, and the agent wanted to make sure all my pics and stuff were backed up.
Has anyone else experienced anything like this? Do my issues make any sense at all?
Smart phone/Android newbie here, please be gentle
