Why do some short messages on my mobile phone automatically close after being opened?

2. There is something wrong with the mobile phone program.

solution

1, the phone memory is full. This situation is generally common in non-smart phones, thinking that the storage space of non-smart phones is generally limited, and many text messages are saved to the saved mobile phone card by default, while the storage capacity of mobile phone cards is small, which is generally easy to be full. At this time, you need to delete some short messages or other things that occupy memory.

2, mobile phone settings. In this case, a certain setting of the mobile phone was unexpectedly changed at a certain time, which caused the mobile phone to be unable to receive short messages. This situation may be that you have personalized settings recently and changed some system settings, so go to the phone settings and click "Backup Reset".
