Why install an APK file Usually, APK files get leaked before time and this allows you to have an easy access to many new features that would not have been availed to you. There are also some apps that certain regions can actually restrict. Having the APK files allows one to be able to bypass the various carriers so as to have the very latest updates on Google. This can take a lot of time to arrive on the network.
In the Android device you are using doesn’t have access to the play site, then installing the apps may require having the APK files and it may be the only option that you have. When using this method, you need to be careful not to end up with apps that aren’t legally acquired. There are services that may allow the download of apps that are pirated. Do your research so as to avoid breaking laws.
