It was over a year ago Google released the first developer preview of Android 7.0 Nougat. Now, a new report claims to have the skinny on Android O, which could be unveiled by the search giant any day now.

According to 9to5Google, the upcoming release will be a “substantial update” with revamped notifications, app icon badges, picture-in-picture mode, and much more. The report also talks about a feature that will restrict background activities from apps, which could help optimize battery life.

Many of the features in the report don’t identify precisely how things are changing, just that they are. Much of the information is simply speculation, so the final product could be much different compared to what’s in the report.

For example, 9to5Google says there will be notification improvements, but it’s unclear exactly what will change. Apparently, Android O will incorporate features that were being built for Google’s Andromeda project, which is apparently no longer being developed.

Android is said to feature “notification syncing” across devices, with the ability to intelligently display notifications “only on the device that the user is currently using.” 9to5Google adds, “Notifications will in essence try to determine how they’re displayed and on which devices based on a variety of factors, including location, time, and the device you’re using.”

And much more

9to5Google’s report covers a wide variety of anticipated features though most of it is speculation. However, the site gives these rumors a high confidence score, so much of what’s being reported may turn up in Android O, which will likely debut at Google I/O in May.

Check out 9to5Google’s report for a more comprehensive look at what features Android O may include. Although Android Nougat has only been available to consumers since last August, Google unveiled the software over a year ago, so we’re about due to learn about what’s next.
