Android 5.1 OS update now rolling out to second-gen Moto X users on US Cellular and AT&T

Google's more recent Android 5.1 (Lollipop) OS upgrade is available for second-gen Motorola Moto X users having subscribed to US Cellular and AT&T's wireless services.

Motorola's senior director of software product management David Schuster has officially announced the roll-out of Android 5.1 to users on the two networks. Users can check for an over-the-air (OTA) notification indicating the update.

What's new with Android 5.1

• Notifications and Interruptions: You can now alter notification volume controls while media is playing. With the volume controls showing, a tap on the bell icon will bring up notification volume controls along with adding icons to the volume settings panel that match those that will show in the status bar.

• Quick Settings: You can quickly select different Wi-Fi access points or different paired Bluetooth devices with a new pull-down menu on each tile.

• Chop twice for flashlight: To turn on the flashlight, second-gen Moto X users need to hold the handset and flick the phone twice and the flashlight comes on. To switch off the flashlight, users need to repeat the gesture.

• Device Protection: Lost or stolen devices will remain locked until you sign in with your Google account, even if reset to factory settings.

• Heads-up notifications: In addition to dismissing a heads-up notification, you can now swipe it up to remove it from your screen. It will remain in your notifications tray and you can dismiss it later.

Bug fixes:

• Clock in the status bar isn't updating and alarms are not going off
• Can't delete SMS messages when the SIM card is full
• No ringer audio while making an outgoing call
• Calculator floating point calculations
• Chrome crashes on launch
• Frequent restarts while watching Netflix
• Wi-Fi will not automatically reconnect to your home Wi-Fi
• Wi-Fi not connecting after being idle all night
• Wi-Fi connection issues with multiple routers in one location
• Bluetooth discovery is not triggered when you refresh settings
• CPU wakelocks that contribute to heavier battery drain
• Connection and synchronisation issues with MS Exchange servers
• Incorrect default APN
• Can't unlock the SIM with a PIN/PUK code
• Can't play 'pinned' content
• General stability improvements

Android 5.1 is already seeding to Verizon's second-gen Moto X users in US and to LTE variants of Cricket-driven Moto E devices across the country.

Moreover, the Moto X can now be customised by buyers (using Moto Maker) for an off-contract price of $299.
