I have had the my G2 since September and have absolutely loved it. A couple of weeks ago, it seemed to get a little "twitchy" with some erratic touch screen behavior (delayed responsiveness, over responsiveness, etc). Then, one day, the "knock on" (double tap to wake up phone) feature quit. Then numerous apps began not working correctly. I uninstalled the 2 apps that have been installed in the last couple months as well as a few others and the problem didn't change. Then, went to put the apps back on and the "install" button in play store is unresponsive. The rest of the screen works fine, just not that little button. Also, the screen that drops down to tell you the notifications on the top bar is super finicky all of a sudden. Checked all settings, tweaked settings, rebooted, Did a hard reboot, safe mode, and factory reset. No resolve. I am not a "heavy" user, only about 10 apps total installed on my phone in the 7 months I've had it. Frustration is mounting and I really don't want to have to take it in. I've already lost all of the settings and everything I had to personalize my phone…Taking it in is last resort. Please Help!
