Well, the mystery is now over. Brief Mobile just posted up a massive gallery of the Samsung Nexus 10, along with screenshots from the software its running, which as expected, is Android 4.2.

It’s definitely the device that we saw posted up in a user manual yesterday, sports a super high-resolution display, front speakers, front and rear cameras, and looks extra-bubbly, which could mean it’ll feel great in hand. The specs are listed below, but it’s definitely running an Exynos 5 dual-core processor clocked at 1.7GHz, 2GB RAM, 16GB internal storage, NFC, and is WiFi only.

On the software side of things, Android 4.2 is still Jelly Bean, but includes a bunch of new goodies, like multi-user support, a Quick Settings menu for toggling off WiFi or switching between users, new camera software (Thank the lord!), and some other minor visual tweaks.

Is Google looking to introduce a second notification menu in Android 4.2 that will contain quick settings? According to the video below, purportedly from from an LG Nexus 4 running Android 4.2, the build has a second pulldown menu with a placeholder image that reads “Future Site of Quick Settings.” Yep, it’s the picture you are seeing above.

To access it, you will have to swipe down your main notification menu, followed by a second swipe down from your notification bar. The quick settings menu should then overlap your main notifications menu, giving you access to toggles for WiFi, Bluetooth, Airplane mode, etc. It’s actually a brilliant idea, but as you’ll see in the video, there are no quick settings there yet, just the placeholder image.
