My phone became almost unresponsive. When in portrait mode, if I clicked an icon at the top of the home screen, the button that would actually get selected was the one at the bottom. My screen lock thing that you have to slide to unlock also was not working almost each time that I tried to slide it. I also tried powering off by holding the power button, but I could not select anything. It would not respond to my touch. After I uninstalled GO Launcher, it worked fine again. Then, I reinstalled GO Launcher and it was the newer version. I only dl GL about two weeks ago. Do you think there being a new version available caused the issue...or was it the fact that I have rooted my phone and made it so that I can install ROMs? I have not actually installed a ROM yet. The only other time that I had issues with the screen and menus being unresponsive is when the battery was low. I thought that was the reason. Does that occur when the battery is low? Also, I have an LG Optimus V.
