If you needed any further proof that Android 4.3 was, in fact, real and headed to Android devices in the very near future, look no further than the leaked screenshots nabbed by SamMobile. What you’re looking at is test build of Android 4.3 (JWR66N) for the Galaxy S4 Google Play edition, running on a regular ‘ol Galaxy S4.
While we don’t know specifics involving the exact changes from 4.2.2. to 4.3, it’s said we could finally see Bluetooth improvements, as well as that new fangled camera application currently found on the Google Play edition HTC One and GS4 running 4.2.2. When it comes to the camera, that can already be downloaded/sideloaded onto your device like any other app. Works without a hitch on most devices.

Guess OEM’s are already prepping 4.3 for their devices, and an announcement of some sort is imminent. We’ll keep an eye out.
