How to install .apk files on Android
You can download an .apk file either using your computer or directly to your smartphone using an Internet browser. If you choose to use a computer, then you need to transfer the file to your mobile device. The easiest way to do this is by connecting it with a USB cable. Then all that remains is to throw the APK file into the Download folder or any other folder.
If the device does not want to give you access to the file system when connecting to your computer, then go to "Settings" and go to "For Developers", find and activate "Debugging via USB"
Now you only need to find the right .apk file using the file manager and run it.
At this point a warning will appear about installing from an unknown source, all you have to do is to allow the installation and that's it! Waiting a little bit and returning to the main screen you will see an icon of the installed application!
