Android 5.1 Lollipop

The Android 5.1 Lollipop update has been rolling out beyond those early-release Android One devices for a few weeks now, and while not every Nexus has 5.1 yet, a new security feature has just been rolled out to both Android 5.1 and 5.0: ''on-body detection.'' Head to the updated section below to see how it works and for more info on the Android 5.1 Android update.

Update: Smart Lock is a security feature in Android 5.0+ that allows you to set certain objects (like smartwatches), locations (like your home or office) or your face as ''trusted'' - this means that when your watch is near your phone, you're at home or work or your front-facing camera can see you that your lock screen security will be switched off and pressing the power button on your phone will take you straight to the home screen.
''On-body detection'' has now been added to devices running Android 5.0 and above. The way on-body detection works is that once you've unlocked your device with a pattern or PIN it won't re-lock until it is set down. If you continue to hold your phone or put it in your pocket or bag it will remain unlocked. The process works with your device's accelerometer, so if you're laying in bed and hold your phone particularly still you will be prompted to re-renter your lock screen security.

Android 5.1 Android update

The Android team has officially announced the Android 5.1 update on its official Android blog. The announcement comes complete with a few update details, including support for multiple SIM cards, Device Protection and high definition (HD) voice. You'll also get Wi-Fi and Bluetooth shortcuts in Quick Settings.
There's no details on scheduling for which devices and when, but you can start the good old button mash cycle right now. Head to Settings > About Phone > Software Update and get busy. If you're rocking a Motorola phone, Nexus device or Google Play Edition you're likely to be first in line for the update.
We'll do some button mashing ourselves and bring you more on the Android 5.1 update as soon as we have it, as well as a install tutorial as soon as the factory images are available.
