COMPLETION ANSWER: Poor answer quality
When it comes to Samsung phones with a screen where part of the screen is bad (especially after being dropped), it almost always leads to a replacement screen :-(. The issue with Samsung phones has always been screen cost; for example, I have someone on the family side who has the S22+. He managed to break this one, too, and he broke it, increasing the high score to 7 devices killed due to screens. Sigh :/...
In regards to the 7 device high score: I gave up trying to mitigate it. I already decided against repair because I can buy the U1 variant of his phone for a little more and ditch the U carrier-locked version. I just assume he's going to need a new phone in 2-3 years, and the screen will be broken by then.
The guide posted by @timtomissus is correct for your phone, but you almost certainly damaged the screen and have to spend close to ~$250 to fix this phone.

I have a similar problem, my phone was dropped & cracked, screen was only showing the top half. Didn't notice any flickering until after the screen was replaced. I've done everything that the internet says to do with no result other than I have waisted several hours taking the phone apart twice & hours upon hours of reading the same "solutions" that does not seem to be working.
All I know to do now is to return the screen. I'm tired of messing with this P.O.S.
(Brand newish Samsung S22 Ultra.)

So you have half of the screen no touch responding?
