Google’s finally announced its Android 5.1 Lollipop update for Nexus smartphones and tablets and today would be the official start of the Android 5.1 release date. The new release focuses on supporting features that usually depend on extra software to work, such as multiple SIM cards and higher-quality HD voice calls on networks like T-mobile or Verizon. You can control WiFi networks and Bluetooth devices from the quick settings area, too.
However, the biggest deal is yet to come. It may be something you’ll hopefully never have to use – Device Protection. Android 5.1 will let you require a Google account sign-in if your device is stolen, even if it’s reset to factory settings. In other words, a thief can’t simply wipe the storage on your phone and pawn it off. The feature will only be available on hardware shipping with 5.1 as well as the Nexus 6 and Nexus 9, but it could reduce the incentives to swipe your stuff in the long run.
The availability of Android 5.1. depends on the gadgets you are using. T-Mobile in USA has already hinted that the Nexus4, 5 and 7 (2013) could already get the upgrades. It is reasonable to presume that the Nexus 6 and 9 will be part of this first wave. As for others, need to wait – HTC, Samsung and other vendors are still finishing their 5.0 rollouts, so it could be a while longer before they catch up.
