Nexus 4 Droid Touch screen became unresponsive

Hi,
After the installation of Android 4.3 on Nexus 4 Droid, touch screen became totally unresponsive. It is working like an alien device. Sometimes, it automatically unlocks the screen but most of the time, it doesn't do anything even after tapping the different parts of screen.
Can you provide some help?

I think you this problem must be due to screen guard. Your screen guard went old and i think you need to change your screen guard. Ohter wise touch screen is unresponsive then you must make it check by your nearest service center.
