When they were released in April 2015, the Galaxy S6 and S6 Edge ran on Android 5.02 Lollipop and T-Mobile started rolling out the Android 6.0.1 Marshmallow at the end of May. Now, this carrier is pushing out a new update to these two flagships and the file weighs in at 250MB, containing the Android security patch for the month of June.

Galaxy S6 and S6 Edge owners who opted for T-Mobile’s services are upgrading their devices’ software version to G920TUVU4EPF1 and G925TUVU3EPD1, and it’s important to install this update because it comes with bug fixes and improvements to anti-theft functionality. The update is rolled out via OTA, which means that it will take a few days until it will reach all users, but if you’re impatient, you can manually attempt to force it by going to the Settings menu and tapping on About Device, then on System Updates.

The Galaxy S6 and S6 Edge have almost identical designs, featuring glass backs and metal frame, but the latter has a frame that wraps around the dual-edge screen. Their dimensions are slightly different, as follows: the S6 measures142.1 x 70.1 x 7 mm, resulting in a total weight of 132grams, while the S6 Edge is 6grams heavier and measures 143.4 x 70.5 x 6.8 mm.

Both devices have a 5.1-inch Super AMOLED screen with a QHD resolution that gives 577ppi, they’re powered by an Exynos 7420 octa core processor with four cores clocked at 1.5GHz and four cores clocked at 2.1GHz, which are backed by 3GB of RAM, and have three variants of internal memories with capacities of 32Gb, 64GB and 128GB, but they don’t support expansion. The rear camera has a decent resolution of 16 MP and supports an aperture of f/1.9, as well as features such as OIS, autofocus and LED flash, while the secondary camera is 5MP. The S6 has a 2550mAh battery and the dual-edge variant gained 50mAh of juice for the extra portion of screen.
