Android 10 finally hit the MI9T.
Any specific features or functions I should be aware of? I read up on some of the bigger additions (Dark Mode!) but I'm still a general Android novice.
Well, MIUI 11already had darkmode without Android 10, though now there's support for Dark Mode notifications as well, which fit much better. MIUI also had excellent gesture navigation, IMO better than stock A10, so that's another important A10 feature that was already in MIUI 11.
On the whole, many of A10's prominent front facing features wil not be seen in Xiaomi devices, mostly because MIUI reshapes the UI so thoroughly. So most of the changes will be under the hood.
One of A10s features is Notification priority, so you can group them into different buckets depending on how important they are to you.
Another cool new A10 feature is the ability to prevent Apps from using GPS in the background. So you can now limit, say, Facebook, from polling your location and instead will only be ale to get that information while you're actively using the app in the foreground.
Android 10 also has native support for Dualshock 4 and the Xbox One controller. Unfortunately, for some reason MIUI blocks the DS4 from working on the PS4 Remote Play app. I don't know if this is a bug or intended behaviour.
There are some cool A10 features that, unfortunately, are not in MIUI 11. Most notably, there's no interactive seekbars in media notifications.
If you want an in-depth look into A10,
here's a great article.
