Screen is irresponsive to touch

Hello

my iPhone felt down ( very good one)

when I got it the screen was ok

when I try to unlock the screen through side button, it unlocks

but screen is irresponsive to touch

I can’t touch for like a one minute

after several trails of pushing the side button to open and close the screen finally it responds and then touch screen becomes perfect and fast until I lock the screen again

I tried to update the phone

force locking it , tried removing screen protectors

but nothing

but it seems like a hardware issue somehow because it started after the fall immediately

I called someone to fix it ( no apple store in my area) he suggested to replace the screen, and I don’t think I will need to change the screen , As it looks intact and eventually responds very good

maybe just to get it removed and placed again ?!

now few times a day the problem is not there

but most of time it’s there
