AT&T has released the Lollipop update for both the Samsung Galaxy S5 Active and the Galaxy Alpha.
AT&T customers who own either the Samsung Galaxy S5 Active or Galaxy Alpha will be pleased to see the Lollipop update arriving on their device. The update bumps both devices up to Android 5.0, bringing along many new features. Lollipop brings Google's Material Design along with enhanced notification handling, Smart Lock, and many other features to both devices.
On the Galaxy S5 Active the update comes in at around 1.4GB in size, while the Galaxy Alpha update is right around 1GB. Both updates are rolling out slowly, so it may be a day or two before you see the notification on your device. You will want to make sure your device is charged up, and connected to Wi-Fi before starting the download.
