Of course, it wouldn't be Google I/O without info on the newest Android OS. This time around Android M is on the pedestal as the folks at Google showed off its fresh new innovations. Here's a breakdown highlight of its most stand-out changes in a quote from BGR,

Google Now on Tap: Google Now has always been a fantastic feature that gives you important contextual information before you even think to ask for it. Google taking it to the next level with Google Now on Tap, a new update that will offer you even more contextual information than ever before.

How good is Now on Tap? If you’re playing a song by Rihanna and you ask “What’s her full name?”, Google will be able to tell you that it’s “Robyn Rihanna Fenty.” Or if you’re driving a rental car, Google might let you know about nearby gas stations when you’re close to the end of your trip so you don’t drop it off with an empty tank.

Granular app permissions: Have you ever gone to download a cheap Flappy Bird knockoff and been horrified that it wants access to your contacts list, camera and microphone? Well Google’s aiming to put a stop to shady app permissions requests with a new system that will let you grant permissions for apps individually instead of giving them to you as an all-or-nothing proposition in the Google Play Store.

So let’s say you’re playing your Flappy Bird knockoff and the app wants access to your microphone to enable a certain feature you’re trying to use. Now it will ask you for permission to do so and you can deny its request while still being able to play the game as you were before.

Support for fingerprint scanning: Many Android phones already have fingerprint scanners installed but now Google is adding universal support for fingerprint scanning across its entire platform. This likely means we should expect fingerprint scanners to be features in all major flagship Android phones going forward, which should certainly help Google push our next exciting feature…

Android Pay: Yes, Google tried the digital wallet once before with Google Wallet but that never really caught on. Now with the addition of fingerprint scanner support in Android M, Google is giving it another shot with Android Pay. Google says that 700,000 retail locations will support Android Pay when it releases this fall, although whether mobile payments will really ever catch on is still an open question.

Doze: Finally, this feature is designed to combat the ever-present problem of battery drain on Android devices. Doze will use your device’s sensors to tell when you haven’t been using it for a while and it will shut off all your phone’s background activity until you pick it up again. At the very least this should significantly increase the standby battery life of your device even if it doesn’t do much to improve your device’s battery consumption during actual use.
What do you guys think of Android M's biggest changes?
