Why have you read all the information, or is there a digital Huawei?

Huawei's SMS icon shows unread SMS, which cannot be cancelled. The following methods can be used to solve the problem:

1.

Turn off reservationless activities in the developer options, and turn off reservationless activities in the application-settings-developer options (some model developer options are hidden).

2. It may be caused by information data error. Click Application-Settings-(More/General)-Application Manager-All-Information-Clear Data.

3. Please update the mobile phone software to the latest version, and apply-Settings-My Device-System Update (pay attention to backup the important data of the mobile phone).

4. If not, please back up the data of the mobile phone and restore the factory settings of the mobile phone (Settings-Reset/Privacy-Restore Factory Settings).
