Text messages can't be deleted, no matter what.

Android SMS can't be deleted. Treatment method:

First, the mobile phone system time is wrong, please manually set it to the current correct time;

2. Some mobile phones have encrypted mailboxes. Please check the encrypted mail.

3. Intercepted messages need to be viewed and deleted in the interception function, or deleted after being restored to the inbox;

4. If the Android phone still can't delete suggestions through the above methods, go to phone settings-application management-all-SMS and then select clear data (and then go to SMS function to delete again);

Fifth, try to use other third-party SMS tools to delete (try to download and install SMS in any market);

Sixth, back up the data to restore the factory settings, or seek after-sales help.
