I downloaded apk files from Chrome. After the downloads completed, I pressed
Install. But after 2~3 seconds, it just said
App not installed. For example, I downloaded an app called "TutuApp". It won't install and doesn't give any information on why so I can fix it.
Anyone knows how to fix this?
My phone is Huawei Mate 9 with Android version 8.0.0. I'm new to Android and a complete noob.
