Although currently there are quite a number of dual SIM android phones, Google is finally brining some support with this new version. Google describes Android 5.1 being able to manage more than one SIM card and we're not too sure what exactly does that translate to in terms of real world usage.
Another highlight feature on this new version is device protection which aims to aid in helping you secure your lost or stolen device. With this enabled, your device will remain locked even if the perpetrator factory data resets your phone but your google password will still be required to access the phone. This looks to be a pretty near feature which builds upon the existing Android device manager apps which allows users to remotely lock or locate their missing phone. However, currently only the Nexus 6 and Nexus 9 will be able to take advantage of this feature for now.
Finally, HD calls will be activated on devices capable of this feature and given that the wireless network activates this feature. This is similar to VoLTE but the HD voices will propagate only through supported devices like the Nexus 6 on T-Mobile or Verizon.
So, Nexus users get ready your Nexus devices for this minor update. Google did not specify which device would get the update but devices currently running Android Lollipop will most likely receive this update shortly.
