Android versions 5.0 and 5.1: Lollipop

Google essentially reinvented Android — again — with its Android 5.0 Lollipop release in the fall of 2014. Lollipop launched the still-present-today Material Design standard, which brought a whole new look that extended across all of Android, its apps and even other Google products.

The card-based concept that had been scattered throughout Android became a core UI pattern — one that would guide the appearance of everything from notifications, which now showed up on the lock screen for at-a-glance access, to the Recent Apps list, which took on an unabashedly card-based appearance.

Lollipop and the onset of Material Design.

Lollipop introduced a slew of new features into Android, including truly hands-free voice control via the "OK, Google" command, support for multiple users on phones and a priority mode for better notification management. It changed so much, unfortunately, that it also introduced a bunch of troubling bugs, many of which wouldn't be fully ironed out until the following year's 5.1 release.

Android version 6.0: Marshmallow

In the grand scheme of things, 2015's Marshmallow was a fairly minor Android release — one that seemed more like a 0.1-level update than anything deserving of a full number bump. But it started the trend of Google releasing one major Android version per year and that version always receiving its own whole number.

Marshmallow's most attention-grabbing element was a screen-search feature called Now On Tap — something that, as I said at the time, had tons of potential that wasn't fully tapped. Google never quite perfected the system and ended up quietly retiring its brand and moving it out of the forefront the following year.

Marshmallow and the almost-brilliance of Google Now on Tap.

Android 6.0 did introduce some stuff with lasting impact, though, including more granular app permissions, support for fingerprint readers, and support for USB-C.

Android versions 7.0 and 7.1: Nougat

Google's 2016 Android Nougat releases provided Android with a native split-screen mode, a new bundled-by-app system for organizing notifications, and a Data Saver feature. Nougat added some smaller but still significant features, too, like an Alt-Tab-like shortcut for snapping between apps.

Perhaps most pivotal among Nougat's enhancements, however, was the launch of the Google Assistant — which came alongside the announcement of Google's first fully self-made phone, the Pixel, about two months after Nougat's debut. The Assistant would go on to become a critical component of Android and most other Google products and is arguably the company's foremost effort today.

Android version 8.0 and 8.1: Oreo

Android Oreo added a variety of niceties to the platform, including a native picture-in-picture mode, a notification snoozing option, and notification channels that offer fine control over how apps can alert you.

Oreo adds several significant features to the operating system, including a new picture-in-picture mode.

The 2017 release also included some noteworthy elements that furthered Google's goal of aligning Android and Chrome OS and improving the experience of using Android apps on Chromebooks, and it was the first Android version to feature Project Treble — an ambitious effort to create a modular base for Android's code with the hope of making it easier for device-makers to provide timely software updates.

Android version 9: Pie

The freshly baked scent of Android Pie, a.k.a. Android 9, wafted into the Android ecosystem in August of 2018. Pie's most transformative change was its hybrid gesture/button navigation system, which traded Android's traditional Back, Home, and Overview keys for a large, multifunctional Home button and a small Back button that appeared alongside it as needed.

Android 9 introduced a short-lived setup for getting around phones with a mix of both gestures and buttons.

Pie included some noteworthy productivity features, too, such as a universal suggested-reply system for messaging notifications, a new dashboard of Digital Wellbeing controls, and more intelligent systems for power and screen brightness management. And, of course, there was no shortage of smaller but still-significant advancements hidden throughout Pie's filling, including a smarter way to handle Wi-Fi hotspots, a welcome twist to Android's Battery Saver mode, and a variety of privacy and security enhancements.

Android version 10

Google released Android 10 — the first Android version to shed its letter and be known simply by a number, with no dessert-themed moniker attached — in September of 2019. The software brings about a totally reimagined interface for Android gestures, this time doing away with the tappable Back button altogether and relying on a completely swipe-driven approach to system navigation. (If you so choose, that is; unlike Pie, Android 10 also includes the traditional Android three-button navigation system as an option on all phones.)

Under the hood, Android 10 introduces a new setup for hot-fix-style updates that'll eventually allow for faster and more consistent rollouts of small, narrowly focused patches. And the software has plenty of other quietly important improvements, including an updated permissions system that gives you more control over exactly how and when apps are able to access location data as well as an expanded system for protecting unique device identifiers (which can be used to track a device's activity over time).

Android 10's new privacy permissions model adds some much-needed nuance into the realm of location data.

Beyond that, Android 10 includes a system-wide dark theme, a new Focus Mode that lets you limit distractions from specific apps with the tap of an on-screen button, and a long-overdue overhaul of Android's sharing menu. It also lays the groundwork for a new Live Caption feature that'll allow you to generate on-the-fly visual captions for any media playing on your phone — videos, podcasts, or even just regular ol' voice recordings — though that feature wasn't available immediately upon the software's launch and is expected to arrive starting with Pixel phones sometime later this year.
