Samsung i9300 mobile phone short message can't be opened, how to solve it?

Try viewing other text messages. Some text messages may have compatibility problems.

If you can't open all the short messages in your mobile phone, it is recommended to go to Application → Settings → General → Application Manager → All → Open information → Clear data.

Back up the data in the mobile phone and restore the mobile phone to the factory settings.

Check whether the phone has firmware or system push notifications. If yes, please upgrade your phone to the latest version. View mode: Settings → General → About Equipment → System Update → Update.

If the problem still exists, it is recommended to take the purchase invoice and mobile phone to the after-sales service center for testing.

I suggest you go to the SMS service center first.

If it is still unresolved, please be sure to bring your purchase invoice, warranty card and mobile phone to the local Samsung service station for testing.
