Micro-signal to retrieve password. Why did I get stuck when I received the SMS verification code?

The reason why the micro-signal retrieved the password and received the SMS verification code is because the running memory of the mobile phone or the built-in storage space of the mobile phone is seriously insufficient. When the micro-signal retrieves the password and receives the SMS verification code, the system pressure caused by insufficient memory and normal operation is stuck. You can delete some unused software, photos and information, then refresh and try again.
