Several users are getting the “App not Installed” on their Android phone when they try to install an application from third-party websites or other sources rather than Google play store.
Most of the time this problem can be caused by the following number of reasons:
There can be two types of locations for phones, internal and external. Depending on the application it might work well in Internal rather than on an SD card and this can cause the installation failure.
The common problem most users face is insufficient space on their phones. Every application has a different size and usage which can impact your phone storage.
If the application you are trying to install on your phone is not compatible with your phone, then it can’t be installed and an error will occur.
Our phones are secured by Google’s security, which keeps the harmful applications away from our phone, and if it’s already in the phone it notifies the user about the threat.

It checks your device for potentially harmful apps from other sources. These harmful apps are sometimes called malware.
