What is the problem that SMS can't be deleted? What is the method?

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

2. Open Settings-Applications-Manage Applications-All-Information, and then click to clear the 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 upgrade to the new version and try it. If it doesn't work, don't use this software. Don't worry, the communication of the mobile phone can be used after unloading, but it is not as smart as the previous mobile phone.

4. None of the first three methods works. You can only make a backup and restore the factory settings. You can basically solve it here, but 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, please update it. This BUG may be fixed in the new version.
