Signature exception occurs because repeated installation of the software leads to inconsistent signatures, and the software needs to be uninstalled and reinstalled.
Inconsistent signatures may be caused by the loss or damage of downloaded installation package data, unstable connection between the currently used network and the upgrade server, packet loss when downloading the system update package, or failure in checking the update package. You can download and install again when the network conditions are good.
For incompatible applications, Huawei's application market will prompt incompatibility.
If Huawei's application market tips are not compatible, it is recommended to consult the developer of the application to see if there is a mobile version of the application for compatible users to download.
The above is the content of Huawei's not installed software signature. I hope it helps you.
