Low storage – Android software and if data such as photos, videos, music, messages, Apps, contacts, emails, etc are stored in the internal memory there is not adequate storage left for another App, leading to Android App not installed error.

Corrupted App file – When you don’t download apps from the Play Store and choose another platform to do that, Those App files are mostly corrupt and cannot installed on your device. I personally recommend you not to download apk from other sources/website

SD Card is not mounted – When your phone is connected to your PC device which can access the SD Card from your device. In that situations, if you install an App and choose to save it to your SD Card, you will see Android App not installed error because the App cannot find the SD card as it is not mounted in your device.

App compatibility with Android Version – Some applications on the internet are only meant to work on some Android versions. Installing these applications on newer android versions will show an error.

Application Permission – Application running in the background and App Permission are not new concepts. Such errors can also cause the Unknown Error Code during App installation.

Incorrect file – If you already have an App installed but download another variant with distinct signed or unsigned certificate can also show an error.
