From this, we get a sneak peek of what to expect from the full release later in the year. With the Android 11 developer preview, there looks to be better 5G awareness overall, and better low-latency video decoding for a better streaming experience. There’s also quite a change in the way the OS grants apps permission. This can be sensitive features like your location data or camera. There’s a new option now to allow one-time permissions, which will make the app ask for it again the next time it needs it. Currently, you can choose to deny permissions requested by an app, allow only when the app is in use, or to simply grant it free access whenever it wants it.

Another major change comes in the way the OS handles messaging apps, your chats, and their notification. For one, your conversations will appear in Bubbles, sort of like the Facebook Messenger app. Notifications for them will also all be grouped together. And from there, you’ll be given the ability to reply using images. Other changes that can be found on the Android 11 Developer Preview includes support for more screen types and biometrics,  as well as the interaction between airplane mode and Bluetooth connectivity we reported on earlier.
