On the heels of Apple's smartwatch event the search engine giant Google took the time to steal a lil shine and released version 5.1 of its android os. With the updates to Lollipop comes the ability of HD Voice calling( currently only available on T-Mobile/Verizon) and also brings lock down protection, the ability for your devices to be fully shut down and no accessible in the event it's either stolen or you accidentally misplaced it. No info on which devices will be receiving the update but expect the Nexus 9/7/6 to get first dibs...........
