T-Mobile has released the Android 6.0 Marshmallow software updates for last year's flagship Samsung smartphones, the Galaxy S6 and Galaxy S6 edge. The update has been in the testing phase for several weeks and is now being rolled out to customers owning the devices on the carrier, while AT&T customers who were promised a March upgrade are still waiting for the carrier to release it.
Recently we brought you the news that T-Mobile had been officially testing the Android 6.0 Marshmallow updates for the Samsung Galaxy S6 and Galaxy S6 edge. Previously, the update had been in the first phase of T-Mobile development as indicated on its official software upgrade web page. Towards the end of March, the carrier moved the update status into the second of the three phases indicated on the status page, known as the testing phase.
The status change, based on previous upgrade timetables on other devices on T-Mobile's network, indicated that the update was imminent for the Samsung former flagships, and we are happy to report that it has finally arrived. The Galaxy S6 and S6 edge are both receiving software version UVU3EPD1. Many T-Mobile customers have already received the update, and those who haven't received an official notification can check their settings for the 1.2 GB system update.
As far as the supersized version of the Galaxy S6 edge, the Galaxy S6 edge+, T-Mobile customers who own that device on the carrier appear to still be in for a significant wait. The S6 edge+ is still listed on the T-Mobile software upgrade page as in the "Manufacturer Development" phase. "Manufacturer Development" is only the first of the three stages T-Mobile uses to label its software upgrade progress, and once a device enters phase two of the process, it generally takes several weeks before the update is ready for release.
Both Sprint and Verizon customers have already received the Android 6.0 Marshmallow software update for the Samsung Galaxy S6, S6 edge and S6 edge+. That leaves AT&T as the only one of the big four wireless carriers who have yet to release the update on any of Samsung's trio of Galaxy S6 variants. The lack of an update has riled up AT&T customers who have watched all three of the carrier's rivals now release the upgrade. To add insult to injury, over a month ago, customer service reps from AT&T gave a release date of March 14 for the Android 6.0 Marshmallow release, but almost a full month later, the upgrade is MIA as is any indication of when it will finally hit the network's Galaxy S6 and its variants.
