Hot on the heels of the LG G2, AT&T’s Samsung Galaxy S5 Active and Galaxy Alpha are now beginning to receive the update to Android 5.0 Lollipop. The Galaxy S5 Active’s update comes in at a hefty 1.4GB download, and the Alpha’s at 1GB. AT&T requires you to download the updates over Wi-Fi, so make sure your phone is charged up and you’re connected to a speedy Wi-Fi network before you start the download.

Just like on most other Samsung devices, the Lollipop update will bring along with it many UI enhancements, but they won’t be very prominent thanks to Samsung’s Touchwiz overlay. Other changes you’ll find in the update include the switch to the Android Runtime (ART), priority mode notification settings, new battery saving features, Smart Lock, more fluid animations and much more.

The updates to both devices are rolling out now, but it may take a few days to make their way to your device. If you’d like to check manually, head to Settings>About device>Software updates>Check for updates. Once the update is downloaded and installed, your Galaxy S5 Active’s software version should now read LRX21T.G870AUCU1BOC5 and your Alpha’s software version will read LRX22G.G850AUCU1BOC6. Be sure to let us know in the comments when you start receiving the update!
