S22 ultra touchscreen issues

[Energisse]

Since today, I'm experiencing touch screen issues on my device. There's a horizontal strip (around 0.5 cm thick) spanning the full width of the screen that doesn't respond to touch properly — sometimes it doesn't register input at all, and other times it triggers random touches on its own.

I updated to One UI 7 about five days ago, but I'm not sure if this is a software-related problem or a hardware issue.
So far, I've already:

Wiped the cache partition

Performed a full factory reset

Unfortunately, the issue persists.

If you've done a full reset, it might just be a hardware issue that happened to occur at the same time as the update.

Try taking it to a samsung store?

Hi! Welcome to the Samsung Members community.

Go to Settings > Security and privacy > turn off Auto Blocker.

Then go to your phone and dial *#0*#.

This should open a menu; open the screen test- does all the screen work ("touch")? If not- hardware issue

Attempt a soft reboot- holding power and volume down. If the line still remains- may be time to contact customer support for a repair

Already tried all of that, including diagnostics through Samsung Members.

Since the phone is no longer under warranty, I’ll probably go through my personal insurance for the repair.

Sorry to hear that!

That seems like the best bet!
