It looks like those rumors about Android O dropping this month were right on target. Google has officially released details on the latest version of their mobile OS, and developer preview images should be rolling out soon for eligible devices. The most significant change for me is “background limits,” which will promote greater battery life by controlling what apps and services may do behind the scenes. (I could have sworn that they already attempted this before, but maybe this is a new, better method.) Android O will also have native Bluetooth aptX support, which should mean better quality wireless audio. As some had expected based on the timing of last year's Android N announcement, Android O was due sooner or later, and today's the big day: Meet Android O. Which, obviously, doesn't have a full name yet, and probably won't for a long time. So for now, just make up conspiracy theories about those concentric circles up there. First, when can you get it? Well, Google says Android O developer preview images should be available for flashing soon (they'll be here), but it's not clear when "soon" is, but we'd tend to assume based on last year that means today. The eligible devices are the Nexus 5X, 6P, Nexus Player, Pixel C, Pixel, and Pixel XL (the Nexus 6 and 9 obviously are end-of-lifed, and won't get O).
