An XDA user spotted the Google Nexus 4 with Android 4.3 at the on-going Thailand Mobile Expo and snapped a few images of this smartphone. While two out of three images just confirm the presence of Android 4.3, one of the images shows Nexus 4 with new camera software on-board, a change from the camera app on Android 4.2.
If you look at the image, you will see that Google has switched the camera controls from circular control panel, which appeared wherever you wanted it, to arc-like control panel on the screen.
Other changes in Android 4.3 are not clear at the moment, but these images once again confirm that Android 4.3 is indeed going to be called Jelly Bean.
As per a recent report, Google is going to announce Android 4.3 and White Nexus 4 smartphone on June 10, so we just have a fortnight more to go and everything will become clear. Check out more images of the phone below.
Update:Now a video of Nexus 4 with Android 4.3 has also appeared on YouTube.
