One of the biggest news characteristics is that the new version of Go, is supposed to work on devices with 2 GB of memory RAM or less - a small increase from Android 10 (Go version), which was created for devices with less than 1,5 GB of RAM. But don't necessarily expect to upgrade your existing 2 GB phone: Android 11 Go is only going to come out for new phones with that much memory, not older ones, according to Google in The Verge.
Google also says it's up to OEMs if they want to install Android 11 Go on a device instead of Android 10 Go, as opposed to what was suggested on a document received by XDA Developers in July. Google would not provide examples of devices that can download it information.
However, if you have a phone that can be upgraded to Android 11 Go right now, you can try new features such as grouped notifications from chat apps on your notifications like Android 11 and grant one-time licenses to apps for things like the microphone or the camera.
Apps will also launch 20% faster than Android 10 Go, according to Google. Android 11 Go also adds a motion-based navigation system that you can use to navigate the phone's user interface.
