It has been said in the past that the Galaxy S6 was going to get Android 8.0 update. Samsung customer care representatives have supposedly confirmed that the device will be getting the update and this month will be the time it rolls out. Confirming this news, the development pages for the Samsung Galaxy S6, S6 edge, S6 edge+, and Note5 on T-Mobile’s site say the carrier and Samsung “have agreed to support a new software update,” which is Android Oreo. Samsung hasn’t released an official announcement about this but we’ll watch for it.
