The team behind Android O did an AMA on Reddit, answering burning questions from the populace. The thread (hit the Source link) is well organized, so do check it out, but here are some highlights.
Project Trebble - phones that launch with Android O will have Trebble out of the box. This project makes it faster and easier for manufacturers to keep their devices updated by providing a clearer separation between hardware and the makerís software. This should reduce the issues with canceled updates because the chipset maker didnít update its drivers.
SafetyNet - if you havenít heard of it, this is a Play Services feature that allows apps to detect if your phone is rooted or not (thereís more to it than this, but still). Google doesnít enforce its usage, so itís up to every app developer to decide for themselves Ė support rooted users or not?
Autofill - starting with O, there will be shared autofill functionality, which will reduce the need to type in the same information across multiple apps. The Google Autofill Provider is already used in Chrome and will soon be enabled in WebView (i.e. apps that use a web-based interface).
Blob emoji - One of the considerations to kill off the blobs is that emojis can be used as stickers in messengers and the team believes the blobs did not look good at a larger scale. Additions to Unicode ďcreated new categories of emojiĒ, which apparently donít mesh well with blobs either.
Themes - basic theming is already supported by Android, but itís not capable enough to replace hard mods like TouchWize/Sense/MIUI. Even simple theming isnít that easy, though, which is why we still donít have a dark Material theme. Also, the team considered coloring the Nav bar same as the status bar, but decided against it.
Vulkan, F2FS - Both are features that the team is looking into, but both are not ready for prime time. Vulkan canít replace OpenGL ES yet because it is not officially required to run Android. F2FS isnít supported for the internal storage as it doesnít support inline hardware encryption.
AOD on Pixel 2 - nope, the team did not answer any questions about the upcoming Pixel sequel.

Tremble isnt auto update it just helps oem to uodate faster regardless of carrier, safetynet is just determines if developer allow apps to work on rooted phone and Im pretty sure they will allow it, autofill and blob yeah no one cares, vulkan may not...
Well, definitely there is so much to say, and almost regarding every single point. But just in a nutshell, basically, the best thing is, that the more options there will be, the more versatile it will be. But even more better than that, is the freedo...
Android O is same old nougat with very minor change to UI not worth the wait google should Change UI to something colorful material design is getting boring.
