My M4 aqua dual touch not responding

[Debayudh]

This morning when I tried to use my phone I saw that my phones touch was not responding but the buttons on the sides are!!!

Need help quickly. How can I fix this issue?

@Debayudh,

Welcome to the community.

You can force your phone to shut down by holding down the power and volume up at the same time. Try turning it off and on again.

Do you see any physical damage on your handset?

I have tried restarting several times but still it's the same.

And there is no physical damage, it all started by its own

@Debayudh,

So your touch screen is still not responding? Try running a software repair and report back.
