Android 5.1 was first seen on an Android One device sold only in India and Google has no word on rolling out the update to other devices, including the Nexus devices which we are expecting to get the update first. Today, Google has finally make the Android 5.1 update official. This update is bringing stability and performance improvement, which will be useful to anyone. There are a few new features introduced too.
Device Protection is designed to lock your lost devices, even after the devices are reset to factory settings. To unlock it, you need to sign in with your Google account. With a tighter policy, we hope that theft can be reduced. Google mentioned that this feature will be available on most Android devices shipped with Android 5.1 in addition to Nexus 6 and Nexus 9. It is still unclear if other current devices will be getting this feature or not.
HD voice calling will be available after this update to make your conversation over the phone crystal clear. Of course, both devices on each end must be compatible for this to work. On the other hand, Android 5.1 finally has multi-Sim support so that devices with multiple SIM slots can take advantage of it. You will be able to join Wi-Fi networks and control paired Bluetooth accessories from the pulled-down Quick Settings menu.
The update itself is not as big as what the x.1 version jump suggests, like what we had back in Android 4.x’s days. Nevertheless, we still welcome the new enhancements. Given that most devices are not getting the slightly older Android 5.0 update and the fragmentation in Android landscape has been quite bad, we really hope that this update will be available for more devices very soon.
