Today we are rolling out Android 5.1 - an update to Lollipop that improves stability and performance and offers a few new features like support for multiple SIM cards, Device Protection and high definition (HD) voice on compatible phones.
Of course, the main thing everyone wants is that memory leaking fixed and the hope that battery life improves as a result!
