Multiple issues just appeared out of nowhere. Home button does not work. Search button (the square) that allows you to switch between open windows does not work. Phone is set to lock with pattern, doesn't lock when power button is pushed or screen times out. Notification bar pulls down, but will not pull down for the whole page of options (wifi settings, USB, flashlight, etc). Have tried off and on, soft reboot, endless hours of googling. Last option is factory reset, but don't want to lose pictures. Cannot transfer them to PC because I cannot change USB setting. No recent apps downloaded, nothing shows up on antivirus scans. Going insane, HELP!!!
