iPhone X touch not issue

Hello punam273,

We see you have an iPhone X with the display not working. The first thing to check is to make sure you walked through all the steps in the article that linked you here.

If the screen isn't working on your iPhone or iPad - Apple Support

If your screen is too sensitive or responds intermittently to touch

1. Restart your iPhone or iPad.

2. Make sure that your screen is clean and free of any debris or water.

3. Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.

4. Remove any cases or screen protectors.

After walking through those steps, if your display still has an issue with touch, the next best recommendation is to reach out to Apple Support teams directly. You can reach them here: Get Support

You can also find the support phone number for your region at this link: Contact Apple for support and service - Apple Support

All the best.
