This bug belongs to the monitor. When reading a short message, the system records it abnormally, so it is displayed as unread. You can click one by one in the short message history, that is, let the system record the "read" status again, and it can be eliminated.

Extended data:

It turns out that the first generation computers were made up of many huge and expensive vacuum tubes, which used a lot of electricity to make the vacuum tubes glow. It may be because of the light and heat generated by the operation of the computer that a bug got into the vacuum tube, which made the whole computer unable to work. It took the researchers half a day to find out why. After removing the bug from the vacuum tube, the computer returned to normal. Later, the term "Bug" was used to refer to a hidden error, defect, loophole or problem in a computer system or program.

Corresponding to bugs, people call the process of finding bugs and correcting them "debugging", which means "catching bugs" or "killing bugs". Unfortunately, in Chinese, there is still no exact word corresponding to "Bug", so we can only quote the word "Bug" directly. Although some people use the word "Bug" instead of "bug", it is easy to cause ambiguity, so it cannot be popularized.
