The official blog of Android developers has published a message about the availability of updates to the latest mobile operating system codenamed Lollipop to version 5.1. Along with improved stability and performance, users of devices running Android 5.1 will also get a number of brand new features such as support for multiple SIM cards, advanced Device Protection technology and HD Voice quality on compatible phones.
According to developers, support for more than one SIM card on an Android 5 device.1 with support for multiple SIM cards will be useful for those who occasionally lend their smartphone for use by other family members. In addition, the flexible use of multiple plans on different SIM cards will help optimize mobile communication costs.
Even if your phone is lost or stolen, Device Protection technology will take care of locking it down until you log into your own Google account and unlock it with your own hands. The lock will be held even if an intruder tries to reset the device to factory settings. According to preliminary reports, Device Protection technology will be supported by most smartphones and tablets, initially shipped with Android 5 pre-installed.1 as well as the Nexus 6 and Nexus 9 systems.
Not only will you need compatible devices like the Nexus 6, but you’ll also need compatible cellular carriers like T-Mobile or Verizon to make the high-quality HD Voice feature work fully. So it’s still unclear whether the HD Voice feature will work on Android 5.1 devices in the American realities.
In addition, the developers also promise owners of devices running Android 5.1 Lollipop expanded wireless capabilities. For example, from now on, compatible devices have the ability to connect to Wi-Fi network and control the device synchronized with it via Bluetooth directly from the Quick Settings panel Quick Settings .
