forward button is not working on touch

Hey there saroj88,

To clarify, does this happen in the same spot on your iPhone when trying to use the touch screen in other apps?

We see you referenced the related article If the screen isn't working on your iPhone or iPad. If you've completed the steps there, please continue to follow the last section:

If your screen still isn't working, you might need to set up service for your device. Contact Apple Support.

Contacting Apple Support will lead you to getting the display fixed.

Take care!
