Android Froyo is the sixth version of Android and is a codename of the Android mobile operating system developed by Google, spanning versions between 2.2 and 2.2.3.[3] Those versions are no longer supported. It was unveiled on May 20, 2010, during the Google I/O 2010 conference. Google ceased sign-in support with a Google account for Android Froyo to Android Gingerbread on September 27, 2021.[4]

One of the most prominent changes in the Froyo release was USB tethering and Wi-Fi hotspot functionality.[5] Other changes include support for the Android Cloud to Device Messaging (C2DM) service, enabling push notifications, additional application speed improvements, implemented through JIT compilation[6] and displayed within applications as top-of-the-screen banners.
