Make it look like your phone is ready to update! Android updates come once every 100 years or so if you don't have a Nexus phone, so why not experience the magic on your phone that will never get past KitKat?
Impress your friends with your phone that was EOLed 5 months after release by showing them you have an update. Then go back to basking in sadness that you didn't get an iPhone or a Nexus device. I'm sure you love your Galaxy Grand Prime Duos Epic 4G.
Backport to older versions of Android. Even your grandpa on Gingerbread can now experience the magic that is updates!
