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.
