We have noticed several people having issues with screen replacements particularly on iPhones with respect to touch input. All of these issues are on devices with iOS 7.X. These issues are not hardware related nor limited to the iPhones: A quick Google search will reveal similar issues with iPads and iPods.

It seems that these issues occur after the battery percentage drops below 20%. Some forums and pages will say it happens exclusively after either the 20% or the 9% battery life warning. The way to fix this is to try the following:

  1. Backup your iOS7 device
  2. Restart the device
  3. Reset the device
  4. Reset all settings
  5. Restore your backup
  6. Restore as a new device

With regards to prevention, all we can try at the moment is to warn people not to let their battery life to drop below 21%. We will have to wait for Apple to patch these issues. There are also some pages saying iOS7 renders phones unresponsive. Be aware!
