Why can’t I download the Wuhai Energy app?

The Wuhai Energy app cannot be downloaded because the switch for downloading applications from unknown sources is turned on. Since you have not turned on the switch for downloading applications from unknown sources in the phone settings, there will be no way to download the software. Then you only need to Open the phone's settings, enter the security settings or developer options, and turn on both the unknown source application download and external source application installation switches to download.
