The text message disappears.

If the messages in your mobile phone are always lost automatically, I suggest you:

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

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

3. Check whether there is virus software in the mobile phone. Check mode: Settings-Application Manager-Run-Check whether there is a Com.android.version process running. If there is this program, please uninstall, delete and restart the phone.

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.
