After I posted on July 21, the Samsung community sent me a link, but when I clicked on it, there was no help at all. Because I can't live without my mobile phone, I bought another Samsung phone. I was busy with work and didn't pay much attention to this S21. It couldn't turn on before. It was the two black photos. In August, it changed to the blue picture with Korean. Now the following screen appears when charging. I tried to restart, but it will continue to return to this interface after restarting, so I can't do anything. It feels like I spent nearly a thousand euros to buy a mobile phone. There is no misconduct or damage, but I can't use it anymore. This makes me very frustrated. I also have an S20 that can't turn on after the update. Samsung has updated the problem, but I have to pay for it, so the new phone I bought is the A40 for 80 pounds, because I think the expensive phone is not worth it.
