Google's official Android YouTube channel just uploaded the video below. Above? A screen capture from it. Android 7.0 Nougat - there you have it. Google revealed the nickname of the latest Android OS earlier this morning along with the mascot you see above.
Android 7.0 follows Android 6.0.1, meaning Android 6 never even had a proper 6.X release. Android 5.0 had 5.1[.1], 4.0 had 4.1 through 4.4[.4], 3.0 had 3.1, 2.0 had 2.1 through 2.3[.7], and 1.0 had 1.1, 1.5, and 1.6.
What does this mean? Frankly, nothing. Almost nothing at all: it's just a number, an easy way to refer back to a particular iteration of the Android operating system. It's always fun to find out, nonetheless. Now, begin clamoring for your respective Android 7.0 OTA.
