Samsung note2 7 102 dual card dual standby SMS background and SMS ringtone settings

According to the situation you described, I suggest you do the following:

1, Settings-Application-Slide Screen Selection (All)-Find Information-Click Enter to try to clear the data.

2. If the problem still exists, it may be the conflict caused by some programs in the mobile phone. Please back up your phone data (phone book, SMS, multimedia materials, etc.). ) and try to restore the phone factory settings (Settings-Reset-Restore Factory Settings).

Note: all the data stored in the mobile phone is lost, so it must be backed up to the sim card and sd card in advance before operation.

Mobile phone custom SMS ringtone:

In the mobile phone: My Files-All Files -sdcard0- Click the menu button in the lower left corner of the screen-Notice of creating a new folder (if there is such a folder, you don't need to create it).

Move music to this folder.

Information-Click the menu key in the lower left corner of the screen-Settings-Notification Information Settings-Label 1 to ring for card 2.

I hope the above reply can help you.
