Amazon Fire Phone Update Brings Multitasking, Better Battery Life and More
Another important feature is Quick Switch, which is something that most smartphones already support in one way or another. Quick Switch lets you swap running apps by double-pressing the Home button. You can use the feature to stop running apps, too, which is handy.

Other features include support for sharing videos via MMS and email and a lenticular photo tool that now uses 11 photos instead of three to create the image. And, the app grid now lets you create folders for your apps.
If you have an Amazon Fire smartphone, all you need to do to get the update is wait. The phone should download and install the update automatically. You can check to see if you have the latest version by swiping down and then tapping Settings, Device, Install System Updates. You should see Fire OS 3.5.1 listed. If an older version appears here, tap Check Now and you’ll be in business.
