What is the tick mark in the lower right corner of Huawei nova7 icon?

This is a sign that the "payment protection center" function in the mobile phone has been turned on. Take Huawei Changxiang 7 mobile phone as an example, which can be viewed in the following ways:

When you turn on the phone, you can see that the WeChat icon on the desktop has a blue checkmark icon. Click Settings on the desktop.

After entering the settings, click "Security and Privacy" on the page.

Enter Security and Privacy, and click "Payment Protection Center" in the page.

After entering the payment protection center, turn off this function.

At this time, I went back to the desktop to check, and the blue checkmark icon on the WeChat icon disappeared.
