My mobile phone is Samsung 7 109. I haven't received any text messages in recent days. I can only look back at the text messages in recent days to know how they were sent.

It is recommended that you:

1. Info-Menu key-Settings-Basic Settings-Delete old information-Uncheck.

2. Clear SMS data: Settings-Application Manager-All Information-Clear Data.

3. Uninstall and delete the recently installed software (excluding whether it is related to the downloaded software).

4. If it is invalid, please back up the information (contacts, text messages, pictures, etc.). ) in the phone, and then restore the factory settings (Settings-Reset/Privacy/Personal-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.
