What to do if a crack on the phone screen imitates a tap on the screen area?

Question

Mobile devices

I dropped my phone a month ago. There was a scratch that didn't bother me much. But this morning I noticed that the phone itself began to open applications. After I enabled the "show presses" function in the developer options, my hypothesis was confirmed that the scratch presses on the phone's screen in such a way that it simulates pressing on the screen.
Naturally, it is impossible to use it normally, so I ask for help.
What can be done? Maybe through some menu to turn off a small part of the screen? Is there such an application? Maybe you can somehow write such a program yourself? (There was an android programming course at the university, I can write simple applications) Or maybe there are some mechanical ideas?

Answer 1

1. You need to change not the screen, but the touch itself
2. Touch, etc. can occur not only from a crack, but also from static or even a bad charger
3. Perhaps there are prints on it or something that causes a touch
4. The touch itself is where the crack is slightly deformed, so you
can’t turn off the desired area, only touch screen replacement

Answer 2

Pull back with a suction cup. But I suspect it won't last long.
