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.
