Samsung's text message disappeared.

According to your description, I suggest you try the following methods:

1. Enter the phone settings-Application Manager-If there is a "com.android.version" program, please uninstall and restart the phone test.

2. Try to replace another SIM card.

3. Check whether the mobile phone is equipped with security guards or third-party SMS software, and test it after unloading.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

5. Try to update the next system version.

If the above method still fails, please send the equipment to Samsung Service Center, and the engineer will check the machine and deal with it. Please click the following link to find out the specific location of Samsung Service Center:.
