My Samsung I699 usually has a prompt when the SMS is sent successfully. How to save it now?

According to your description, if there is no information prompt on the mobile phone, I suggest:

1. Check whether the notification tone on the mobile phone is turned on and turned to the maximum.

2. Check whether the third-party detection software is installed on the machine, uninstall it and try again.

3. Back up the data on the mobile phone, restore the factory settings of the mobile phone, and eliminate the software 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.
