Android 5.1: This is what's new!
It might not appear to be the biggest update in recent memory, but Google's Android 5.1 is actually pretty substantial.
When Google detailed Android 5.1 earlier this month, the search giant mostly glossed over a lot of great features that were added. Some of the bigger ticket items include support for multiple SIM cards, Device Protection and HD voice on compatible phones. But there were other enhancements, too, like system volume tweaks, some new animations, and many more.
