How does Samsung mobile phone make icons display unread messages?

1, enter the information application

2. Click the menu.

Step 3 choose settings

4. Check after selecting the preview information (provided that the notice is checked).

New unread SMS, but the unread display on the icon always exists.

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

1, Settings-Application Manager-All Information-Clear Data

2. Try to restore the factory settings after the important data of the mobile phone is backed up: Setup-Reset-Restore the factory settings (excluding software problems). If it still exists after the above operations, it may be caused by system problems. Please contact Samsung Service Center with your shopping invoice, three-guarantee voucher and mobile phone, and the engineer will check it.
