What is the problem that mobile phone short messages can't be deleted? What is the method?

1. Some mobile phones have the option of restoring the settings in the information settings, which may be deleted when clicked, but some mobile phones do not have this function and can only do the following operations.

2. Open Settings-Applications-Manage Applications-All Information, and then click Clear Data. Most mobile phones can do this, but it's just to erase text messages. The key problem has not been solved, and it may not be deleted next time the information is full.

3. You will find that the current smartphone address book has many functions and can be upgraded like other software, which involves the problem of software bugs. You can go back to the old version or try upgrading to the new version. If not, don't use this software. Don't worry, the communication of the mobile phone can still be used after unloading, but it is not as smart as the previous mobile phone.

4, the first three methods are not good, you can only make a backup and restore the factory settings. It can basically be solved here. If not, you can look at your mobile phone.

5. In case it doesn't work, you can look at the mobile phone settings-about the mobile phone-system update. If there is an updated version, update it. This BUG may be fixed in the new version.
