AT&T has begun rolling out Samsung’s latest Lollipop software for the Galaxy S6 and Galaxy S6 edge. The Android 5.1.1 update brings Samsung Pay, some design and user interface tweaks, and a number of new features.

The update weighs in at just over 660MB, and it is making its way to Galaxy S6 and Galaxy S6 edge owners over-the-air. According to users on the Android Central forum, the full list of changes include the addition of Samsung Pay, ultra high quality (UHQ) audio, and live broadcasting, which lets you stream gameplay directly to YouTube.

Samsung has also made some design changes, tweaking its app icons to make them look identical to those on the Galaxy Note 5 and Galaxy S6 edge+. Users also report a significant performance boost after installing this release.

Like all Android updates, this one will likely rollout in phases, so don’t worry if you haven’t yet received it — just be on the lookout for an update notification. You can also search for the software manually from within the software update section in the Settings app.
