So, I found my old Samsung GTP1000, and wanted to use it. I had some issues while logging into my google account, so I rebooted it, while an account was still connected. However, after rebooting, I tried to log in whit the same credentials and the same account, but it said that credentials arent correct, but I tested the same credentials on other devices and they worked. And also, I couldn't create a new account. It said it had problems with communcating with Google servers.
