Lenovo's short message can't be opened and flashed back.

Lenovo's SMS can't open the flashback phenomenon, and the suggestion can be:

1, try to restart the phone;

2. Verify whether the third-party SMS software clears the SMS software cache (backup SMS, contacts, etc.). Prevent data loss first);

3. Back up data to prevent data loss and restore factory settings.

4, invalid can contact after-sales testing.
