Android 4.3 Is Coming - What To Expect From The Update.
The two images that are being shared has one featuring Android's standard "About phone" settings screen and the other one could be the new camera interface. Since, there were a lot of complaints regarding the AOSP camera controls when Jelly Bean 4.2 was released, this is good news that Google is working on tweaking it for better. The image suggests that there will be a new see-through action area along with a new activation ring and fresh icons for HDR, contrast, and rotation. Though most people are worried that the Android 4.3 update should be more than just camera's setting enhanced, but that's pretty much all the evidence we have right now.
