I've seen posts with similar problems. Freezes, makes calls on it's own, the icons get twitchy, opens the wrong one. The hardware buttons (Return, home, etc.) aren't working right either. I turned off the animations and it helped a little. I see instructions for "Factory Data Reset." What does it mean "Erase EVERYTHING?" Sounds scary. If I get a new phone, what comes with me on the memory card?
Steps Factory Reset below
- From the home screen, select the App menu.
- Select Settings.
If the application icon is missing, select App menu filter (located at the top) then select All apps.
- Select Privacy.
- From the Personal data section, select Factory Data Reset.
- Select Reset phone.
If presented, enter the current pass-code or draw the unlock pattern.
- Select Erase Everything.
Allow up to 3 minutes for the factory data reset and reboot processes to complete.
- Perform initial set up.
