Android 5.1 is the first big maintenance release for Lollipop, fixing bugs and improving performance and stability over the original 5.0 release.
The quick settings panel has been polished up a bit in Android 5.1. Each of the icons comes to life with a new animation when you tap it.
Android 5.1 also introduces dual SIM support as a built-in Android feature. Android 5.1 brings some much-needed clarity to Lollipop's somewhat confusing screen pinning feature, which was designed to make it easier to lock kids or guest users into a particular app.
Device Protection in Android 5.1 will help to secure your device even if it's lost or stolen. With this feature enabled, a thief won't be able to use your device - even after factory resetting it - without having your Google account login details.
And some other minor changes are New animations in Clock app, Contacts lose colored overlay and Google+ linkage, Sticky soft keys fix, Hide 'Heads-up' notifications without dismissing, A new status bar icon when there's no SIM inserted, NuPlayer now the default streaming player.
