6.1 Update killed my touch screen S21+ Ultra

[crazkooter]

The 6.1 upgrade killed my touchscreen. I did have it replaced, probably with an aftermarket from what I've read. Is there a way to revert to the previous version? Not cool Samsung!

It does seem that some non authorised screen replacements have failed after the latest update. It's not known if reverting to the previous OS is fixing it, and besides, the only way is to flash your device, which is not something we can advise. The only recommended course of action is an authorised Samsung repair, but that will incur a cost to you. Obviously, you can seek another 3rd party repair, but there's no guarantee that would work.

There's the usual troubleshooting method of wiping your phones cache partition but unsure it would help with a hardware issue. Unsure how you'd get on anyway if your screen has failed.

I had the exact same problem. what I did was revert back to One UI 6.0 by doing the following:

1. I went to https://samfw.com/firmware/SM-G998N/KOO/G998NKSU4FXD3 

2. I downloaded the firmware that corresponds to my phone (make sure you download the one before the last one).

3. use odin to revert back.

I managed to keep all my files after this but I can't guarantee the same results for anyone else.

here is the tutorial I followed on how to use odin:

I have the same problem, when updating to one ui 6.1!! My model is SM-G988U. I tried to downgrade to version 6.0 of oneUi, but this is no longer possible because the ROM of one ui 6.0 is binary A(10) and oneUi 6.1 is B(11) Samsung made the Downgrade practically impossible to be accomplished.

The exact same problem here! My s21 ultra 5g touchscreen stopped working after the update, i can only manipulate it with otg mouse, and my screen is ORIGINAL!

Think twice before buying a samsung product, THEY ALWAYS FAIL

I have the same problem Samsung should fix it its ridiculous! I have an after market screen costing an eye watering £340 which I only had done as it was my work phone and needed it to work the same day and now I can't use a new phone I have to keep 3 years? I tried wiping the phone still nothing.

I updated yesterday and immediately after I updated. My touch stopped working on my S21+

I successfully downgraded to 6.0 and my phone is back to normal. I had tried all of the recommended "fixes" before the downgrade. For the record my phone is completely OEM, no aftermarket screen and I had the non responsive touchscreen issue. I'm not installing ANY updates until this gets figured out.
