Defective Update (One UI 6.1 ) by Samsung disabled my Screen Touch (S21 Ultra)

[spark_item]

I installed the One UI 6.1 upgrade, which was released on 1 june 2024, on my S21 Ultra 5G (SM-G998U1). As soon as I installed the upgrade it got restarted but disabled the touch screen. I cannot use the touch at all. 

The weakness of the Samsung system has shocked me. I wonder if this update was already tested for safety or Samsung just released it with extreme carelessness. 

I performed the following procedure to get my phone work but could not succeed

1. Restarted (by pressing power+down volume)

2. Clear the Cache (going into the setup)

3. Factory Reset (by losing all my valuable data)

Note: Samsung should come forward and advise a solution to a problem they created. So they are responsible for fixing it in any way.

Same thing happened to me this morning. I purchased a USB C to USB Adapter and plugged a mouse in so I could get back into my phone. I then used smartswitch to dump my new stuff back to my old phone which I luckily still have. Not a solution but might help someone out.

This has been happening for so long it seems yet they are still pushing this "update" out.

Same thing happened to me. After backing up my data with a Bluetooth mouse I've taken it to a mobile phone kiosk outside of Samsung and they have confirmed its 100% software fault. They are going to try and upload new software onto it to fix it so I will try and update you if it works.

Thanks, I hope that works! How absolutely absurd is this...

Yeah I cant wrap my head around it

Hey mate, after talking to a 3rd party technician he replaced the lcd screen and it works after that.
He quoted me £220 for a repair but if you can find a cheaper one online any phone repair shop should be able to fit it for you for about £20-30.
That's all I've got so far, hope this helps.

Still not sure why the update would have triggered our screens in the first place.

Hi, I've experienced the same problem. Unfortunately we need to replace our LCD screens. I'm unsure why the update would have triggered this.
Hope this helps

My phone was new with the original screen, that's insane!

I purchased a new S21 Ultra 5G (SM-G998U1) just two days ago and updated my device to One UI 6.1. When I auto-restarted the device, the touch screen did not work. I used this with a mouse. I am very disappointed. Samsung, please resolve the fast new update.
