Google did not unveil any new Android version at its I/O 2013 developer conference, but Android 4.3 just appeared online in some photos and video.

Google I/O attendees expected the tech giant to make at least some reference about its future plans for Android, but the company decided to stay mum. Rumors of an Android 4.3 version coming ahead of the Android 5.0 Key Lime Pie made rounds ahead of the conference, and now it's clear that Google had a tweaked version under development.

Android 4.3 is expected to comprise of a few minor updates, but a new footage starring the new software version running on the Google Nexus 4 also shows a new camera app.

The video showing off the Google Nexus 4 smartphone rocking Android 4.3 with an updated Camera user interface (UI) surfaced courtesy of XDA Developers Forum members challeen" and innocent36 at the Thailand Mobile Expo 2013 and are available at this thread.

The new Camera app seems to sport a new action area and toggles for contrast, white balance, HDR, rotation and various other things, but the video doesn't show much else regarding other features. It remains unconfirmed for now whether the new Android 4.3 version will sport the same Jelly Bean moniker, but it is expected to do so. The build numbers associated with Android 4.3 server log sightings start with the letter "J," which suggests it's a Jelly Bean version. The Android 4.3 build number on the Nexus 4 is JWR45B in both the photos and in the video.

The video, in fact, shows a pre-release build of JWR45B, as well as a baseband string of m9615a-cefwmazm-2.0.1700.74, which was not used anywhere before this. The pictures, meanwhile, show the About section, the camera's tweaked interface (with the aforementioned controls on the side rather than the focus area), complete with a Jelly Bean Easter Egg adorning the About section.

In conclusion, the pictures and video don't show many changes in terms of design, which means that Android 4.3 will most likely be a minor upgrade, without a radical look or user interface redesign.
