A new version of Android – which was perviously outed on Google’s site for Android One devices – has been made official.
Google announced on 9 March 2015 it had started rolling out Android 5.1, an update to Android Lollipop which it said improves stability and performance in addition to offering new features.
The new features included with the update are:
- Support for multiple SIM cards
- Device protection
- High definition (HD) voice on compatible phones
Stock Android will now let you use more than one SIM card on a device with multiple SIM slots.
Device Protection adds an additional layer of security that keeps your lost or stolen device locked until you sign in with your Google account, even if it is reset to factory settings.
Google indicated that the new security feature is not available on older Nexus devices, but will be available on most Android phones and tablets that ship with Android 5.1, as well as the Nexus 6 and Nexus 9.
The Android 5.1 Lollipop update also includes user interface enhancements, such as the ability to control paired Bluetooth devices and join Wi-Fi networks directly from Quick Settings.
