Dual Sim Support
Devices with the option to use two different SIM cards at once is nothing new. We've seen dual sim devices for years, but each manufacturer or carrier had to add the feature. In Android 5.1 Lollipop Dual-SIM support is baked right into the OS. In the picture you can see the device being able to make a call from the work SIM, or personal SIM. This is a nice touch for those who uses two sim cards in their devices.
The heads up notifications are now slightly different too, but not worth their own slide as it looks the same. Now when you're in an app and get a notification you see a little heads-up notification on the top of the screen. In Android 5.0 swiping up to clear actually clears the notification, and often-times users forget about it. With 5.1 it clears the pop-up, but the notification remains for later so you can interact with it when you're ready.
