I have a Huawei Honor 9X (Android 10 / Emui 10) and would like to install a retail demo so that this advertisement comes from my mobile phone (don't ask why)! I tried to install the apk file, but I always get the error message (screenshot): The app was not installed.
I also have enough free space and it is not due to the unknown sources. So what?
Looking forward to a quick reply.
Then the apk scrap.
Maybe he has a problem with parsing or the certificates don't fit or otherwise
If you can try 100 more times, it won't work.
I had already downloaded the apk file on 5 different pages in different versions and none of them worked.
In settings go to system, about phone, and repeatedly press build number until it asks for your pin. After entering your pin go back to system and scroll down to developer options. There you will find a demo mode option. Enjoy!
