Why does my mobile phone send text messages? But I can't see it! What should I do?

Samsung mobile phones generally recommend the following operations:

1. If only a few short messages can't be opened, there may be compatibility problems. Suggest that the other party try again.

2. If all the short messages can't be opened, please open Settings-(Application)-Application Manager-Find information-back up the short messages and try to clear the data.

3. Check whether there is a new version of the machine system and try to upgrade the system.

4. If it is invalid, back up the data in the machine (contacts, text messages, photos, etc. ) and try to restore the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
