The Android Oreo makes sharing preferences possible. It can simply learn about the user(s) preferences thereby saving time. For example, if the user takes a photo of a receipt, it can suggest an expense-tracking app.
This also works for selfies taken by the user. Android Oreo can easily suggest any social media app. The problem of storage space is also a problem for phone users, no matter the amount of storage space we have.
Now the Android Oreo makes it easier to free up space by automatically freeing up the phone first from cache files in some apps which have exceeded their normal space limit. So apps with limited cache space as designated will be the last to be deleted. This is called the per app disk space quota for cached data.
The Android Oreo supports Wi-Fi Aware by indicating available networks and creating a bi-directional connection with the available services all without using the normal Wi-Fi access point. Another awesome feature is the multitasking on the window of your device.
You can operate multiple operations at the same time without minimizing the applications. This is because it has more than one display window to operate on. So you have the choice of which window to run on.
For those using Nexus and Pixel devices, I am quite sure you all have already seen this new operating system and the wonders it works. But for all of us, we have to wait till we get notified of the upgrade opportunity.
