Sprint, Verizon and AT&T have already rolled out the Android 6.0 Marshmallow update for Samsung Galaxy Note 5. Now, T-Mobile has sent out the firmware update over-the-air to its Galaxy Note 5 handsets in the U.S.

The downloadable file is 1,420MB in size and Galaxy Note 5 owners are advised to have a stable Wi-Fi connection prior to downloading the package. Apart from the usual Marshmallow goodness, GSM Arena says this update also brings in changes to the pre-installed Facebook Messenger, Instagram and WhatsApp, among others.

The Android 6.0.1 Marshmallow update is also being rolled out to T-Mobile’s Samsung Galaxy S6 Edge+ variants. This downloadable package is reportedly 1.34GB. After installation, the software version should show: G928TUVU2DPD1, according to GSM Arena. The key changes include Doze mode, Google Now on Tap and improved app permissions, to name a few.

Carriers usually send out OTA updates in phases, and hence, it might take a couple of days before hitting every Galaxy S6 Edge+ device in the U.S. Alternatively, Galaxy S6 Edge+ owners can navigate to the Settings menu --> About device --> Software update to manually check if they have an update waiting to be installed.

Meanwhile, Samsung Galaxy S6 devices under Telus in Canada have reportedly started receiving the Marshmallow update, Phone Arena noted.

Samsung also started sending out the Android 6.0.1 Marshmallow update to 2014 flagship Galaxy S5 last month in South Korea (model number: “SM-G900L”). However, the Galaxy S5 tied to model number “SM-G900F” is apparently the most widely available S5 variant, GSM Arena noted.

Now, the update, specific to SM-G900F, is reportedly being rolled out in Sri Lanka. Europe and other regions are expected to receive the update soon.
