iPhone X ghost screen

Screen keeps scrolling zooming and doing random stuff. I have to Lock the screen and unlock it to get it back to normal. Support asked me to restore and test. Issue is there on restore too. Device is on latest ios 14.4.2 and issue occurs randomly.

fixing the display I heard cost 29000 with 3 month warranty in authorised apple service Center. I think it’s too costly especially when there are any articles from apple on defective apple x display module.

any assistance will be really be useful for this iPhone lover who cannot afford another iPhone or get the display replaced.
