Typically Android updates take some time before carriers can approve of software for use on their networks. In what can only be described as a refreshing move, Android 5.1 adoption seems to be in full swing. A few weeks ago, we saw T-Mobile push out the update to the Samsung Galaxy S6 and Samsung Galaxy S6 Edge, with US Cellular following suit shortly thereafter.
Today, Sprint is getting on the ball, pushing out updates to both these handsets on their network. This comes in the form of software build G920PVPU2B0F7 for the flat S6, and G925PVPU2B0F7 for the S6 Edge. Sprint reminds us that the rollout can take a few days before you see it on your device, so don’t freak out if you haven’t been prompted.
If you don’t feel like waiting around for your device to notify you of the update, you can always manually check by jumping into your Settings app and selecting About device followed by Check for updates. Good luck!
