I'm trying to download a APK for Spotify premium but because of my phone service (fido) Spotify came pre-installed. When I install the APK it trys to update the pre-installed spotify even though it's disabled. How do I install the APK?
The best way is for you to uninstall the pre-installed Spotify first. You will likely need to "root" your phone. This site has some apps that you can use to root the Samsung A5.
