how to stop auto scrolling in iphone??

Hi Riznym

Thanks for coming to Apple Support Communities for help today.

It sounds like your iPhone X screen may actually be having a touchscreen issue.

"Apple has determined that some iPhone X displays may experience touch issues due to a component that might fail on the display module. An affected device may exhibit the following:

• The display, or part of the display, does not respond or responds intermittently to touch
• The display reacts even though it was not touched"

Please follow these instructions: iPhone X Display Module Replacement Program for Touch Issues.

Have a fantastic day!
