Hello, Yesterday, my Galaxy started experiencing a strange error with every incoming call. I'd see an error box appear and then it would ask me force close and something else I don't remember. I can dial out, but I cannot answer calls and have to force close the phone app. Then I'd see the signal icon turn into that circle-backslash symbol just for a second or two, then the bars would return. Whatever's going on, incoming calls are crashing the phone app and forcing the phone to re-establish the cell signal. And today, I went to use a third-party camera app and it asked me to force close twice. So I tried the core camera app, and it, too, asked me to force close. I use Avast and it hasn't alerted me to a virus or anything. I have it scanning my SD card right now, though. Can anyone help me out? Thank you!
