Google has officially announced Android 5.1 Lollipop update and already started rolling out to Google Nexus devices. The new Android 5.1 Lollipop update brings multiple SIM card support, Device Protection and high definition (HD) voice call. Along with the stated features, the OS update also brings usual stability and boost in the performance.
Device Protection is the key feature added to the Android 5.1 update. This feature will provide better security to your device even when the device is stolen. The thief have to login to the Google account with proper password to unlock the device (even the smartphone is reset to factory settings). But it is still unclear whether the device will be unlocked after flashing with a new ROM.
Android 5.1 Lollipop also supports multiple SIMs on devices that comes with multiple SIM slots. In addition, High Definition voice call supports is also in the list of Android 5.1 update changelogs. The update also provides enhancements such as the ability to join Wi-Fi networks and control the paired Bluetooth devices directly from Quick Settings. These are the few changes we can see in the Android 5.1 update, though Google has not released the list of changelogs.
The Nexus devices are the first to get the Android 5.1 update and then soon rolls out to other devices.
