Touch screen is not working correctly during games and while texting.

Hi Christmas light show guy,
Welcome to the Support Communities!
To address this issue, I would suggest you close all open apps, then restart and reset your iPhone.  Here's how:
iOS: Force an app to close

iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, Reset All Settings on the iPhone.  This information can be found in the iPhone User Guide:
Reset iPhone settings - iPhone
http://help.apple.com/iphone/7/#/iph7a2a9399b
Reset iPhone settings. Go to Settings > General > Reset, then choose
Reset All Settings: All your preferences and settings are reset.
If this does not resolve your issue, you may need to back up your device and restore iOS 7:
