The Sprint updates will ensure that the two handsets have their software ready for when Samsung Pay launches in the US on September 28. Other carriers will have to bring similar updates to the Galaxy S6 and Galaxy S6 edge for the payment system to work. These Samsung Pay-related software updates are only required by these two handsets; the Galaxy Note5 and the Galaxy S6 edge+ already support Samsung Pay out of the box.
Aside from the addition of Samsung Pay, Sprint's updates for the two handsets also bring the live YouTube broadcasting feature that Samsung introduced with the Galaxy Note5 and the Galaxy S6 edge+ as well as support for HQ audio with Samsung headsets. Furthermore, the updates also contain a range of tweaks and bug fixes.
After receiving the updates, the Galaxy S6 will run software version G920PVPU2BOH1, while the Galaxy S6 edge will run version G925PVPU2BOH1. The files are rolling out as we speak, but it may take a while before they reach every S6 and S6 edge on Sprint's network.
