The Samsung Galaxy S5 and Galaxy Note 4 are both currently receiving their Android 6.0 Marshmallow updates on the Verizon network. Galaxy Note 4 owners on both AT&T and T-Mobile have yet to see the update, however, along with users of the Samsung Galaxy S5 on AT&T.

Verizon Wireless owners of two of Samsung's popular former flagship devices are now being treated to a major software upgrade. The carrier has announced it is in the process of updating the OS on both the Galaxy S5 and Galaxy Note 4.

Verizon recently announced the rollout of software version MMB29M.G900VVRU2DPD1 to the Galaxy S5, which, according to the company, "brings the latest Android Marshmallow OS along with Wi-Fi Calling, App icon update, Ultra High Quality Audio and Android for Work" to the two-year-old former Samsung flagship.

Right on the heels of that announcement came the rollout of software version MMB29M.N910VVRU2CPD1 to the Galaxy Note 4, along with a similar changelog for the phablet. Verizon subscribers now join Sprint customers for bragging rights in having the update available on both devices.

While T-Mobile has already released the Marshmallow update for the Samsung Galaxy S5, it still appears there will be a significant wait for the owners of the Galaxy Note 4 on that network. That's because T-Mobile still officially lists the handset in the manufacturer development stage, which is only the initial phase of T-Mobile's three-step upgrade process, with both the testing and final completion phases still in the wings for the phablet.

AT&T is the only carrier of the big 4 that has not released an Marshmallow update for either the Galaxy S5 or Galaxy Note 4. The carrier has been late to the table with regard to software updates as of late, and has given no official indication as to when either of the former Samsung flagships will see the update on its network.
