After I posted on July 21, the Samsung community sent me a link, but it didn't help at all after I clicked on it. Since I can't live without a mobile phone, I bought another Samsung phone. I was busy with work and I didn't care about this S21 anymore. Now when charging, the following screen will appear. I tried to restart, but it will continue to return to this interface after restarting, so I can't do anything. I feel that I spent nearly a thousand euros on a mobile phone, and there was no misconduct or damage, but it can no longer be used. This makes me very frustrated. So the new phone I bought is the A40 for 80 pounds, because I think expensive phones have no value 🤣😂
