It may also be the following situations:
1. In this case, the downloaded software installation package may be incomplete. It is recommended that you download and install after the network is stable.
2. Check whether the phone memory is enough.
3. Check whether other software can be installed normally.
4. It may be due to the compatibility problem between the software version and the mobile phone that it cannot be installed normally. It is recommended to find out whether there are other versions of the software before trying to download and install it.
Huawei mobile phone is developed based on Android version. You can try to download the Android version, but I suggest you download it in Huawei App Store first, because downloading it from other channels will be incompatible, and it is not the master key of the App Store, so it cannot be installed. The master key will be leaked, which requires a key security authority, not a formal application. Can't pretend. The master key will upload other keys stored in the mobile phone and the password will be shared and leaked, so it cannot be installed.
The master key generally refers to the WiFi master key. WiFi master key is an android and iPhone mobile phone application developed by Nanjing Wangshang Network Technology Co., Ltd., which can automatically obtain free Wi-Fi hotspot information around and establish connections. The latest version is 4.3.66. WiFi master key is a free online tool based on the sharing economy model.
