You can't send text messages after the note one phone is automatically updated.

According to your description, the problem you encounter may be related to the software. It is recommended that you try the operation as follows: 1. Check whether the mobile phone has recently downloaded third-party software (security, SMS management, system management software). It may be that the software is incompatible with the mobile phone, so I suggest you try to uninstall it (Settings-Applications-Manage Applications-Select Download-Uninstall).

2. If the problem is not solved, you can back up the telephone materials (phone book, short message information, multimedia materials, etc. ) and restore the factory settings of the mobile phone: Settings-Reset (or Privacy)-Restore the factory settings.

If the problem has not been solved, it may be related to the mobile phone hardware. It is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center, and the engineer will test the mobile phone for you (it is recommended that you contact the service center before going).
