The mobile phone notification bar shows the received information, and the short message bar has no information.

I had one, and the problem was similar. At that time, I really couldn't understand the memory card. After reading the short message, the sign bar still showed unread information.

Because I wanted to change my mobile phone at that time, I took it off and fell (gently). Then I went to the bathroom and came back to install it This situation is generally a problem of system aging. Since it's a stuck problem, try again. If you still don't care, change your mobile phone, but if it has special meaning, it's useless, just indicating that there is something wrong with the text message. I wish you control your mobile phone as soon as it falls. )
