Today when my wife got home she told me that her phone wasn't ringing. When I called her phone to troubleshoot it, I heard the ringtone coming from her earpiece and not the regular loudspeaker ringer, when I hung up the phone, it chirped a note through the ringtone speaker and then the screen went black. I tried several times and still it didn't work. I also noticed that her screen went black every time I called, then an error popup occurred, I selected forceclose and tried again, the same thing happened again, still no ring, and the popup box appeared again stating that a program failed to load, and again gave me the option to force close it, which I did. I noticed that her call log went black every time, then it slowly re-appeared showing missed calls, then it faded out slowly, it was acting really wierd, besides that problem, the widget page was moving very slow, I mean very slow. The widget screen would barely move up or back down at all, and without selecting any app, apps randomly opened by itself. I turned off the phone to see if it would help by rebooting and it didn't. So I pulled the battery that everyone else has been doing and the problem seem to have disappeared. Should I return the phone for a new one? I haven't seen any other post about this issue.
