New Update UI 6.1 touch screen unresponsive on S21

[MPopescu]

After installing the latest update on both phones (S21 5G and S21 5G Ultra 512 GB 16 RAM) the touchscreen became unresponsive. I noticed that the date automatically was changed on both phones to 3rd May 16.00.

The only thing that is working are sides buttons. 

I managed to start the recovery console using:

 1. Side button + Volume down to restart the phone

2. Then very quick I change to Side button + Volume up

I wiped the cache partition and also performed a factory reset on S21 5G but unfortunately did not solve the issues. The only change is that the phone is starting the setup (with a padlock locked on top left corner) a new phone but I cannot interact to set it up.

I assume that the main and major issues are with UI.6.1

Is there anything I can do for downgrading the android/UI and recover the information I have on S21 Ultra?

I hope that there is a quick solution as it is so frustrating for having two top phones and to not be able to use any of them. At the moment I'm lucky to have an A70 with older android and UI but I'm thinking of leaving Samsung after many years and products and not buy any other.

Thank you.

Same exact problem any possibility of a fix?

Some reports are saying this is attributed to an unauthorised screen replacement. Does this apply to your device?

Yes, Screen was replaced on both phones. However, this should not be happening even the new screen is Samsung manufactured or other. Moreover, more people reported this issues for original screens too. This makes me think that Samsung wants to pass the responsibility but also could lead to think they are not use original screens to new products.

The important thing here though is, was it replaced via an authorised Samsung service centre? If so, then you may be covered by a warranty? However, If the repair was unauthorised and carried out by a 3rd party, then Samsung would argue that you are not covered and will have to pay for any repairs.

That aside, and considering the troubleshooting methods you've already tried, the only other option available to you is the dowgrade option. I can't recommend that option or even advise how to do it. You risk bricking your devices permanently.

Have a look at this article. It's regarding the S23 but the bit about Google Discover app may apply to you?

have you found a fix? i have the same problem. i have the z fold 5 since december of last year. it hasn't been to any repairs. after updating the phone this problem occurs multiple times a day.

I have not found any fix and also I have not contacted Samsung as Robin very well explain above as they covered their back and is wasting of time to arguing with them. However I'm still checking different options. If I will manage to fix it (flash the firmware downgrade it even theoretically is not possible) without breaking it, I definitely share the solution with you. Until then I will nove to IPhone after more then 20 years of Samsung fan.
