As you can see in the screenshot above, we can easily spot a bunch of Nexus devices including the Galaxy Nexus, Nexus 4, Nexus 7 and Nexus 10 running a variety of Android 4.3 versions including JWR25C, JWR24B, and JWR29/JWR29B. We also notice a Nexus 4 running build JDQ39 (Android 4.2.2) which is identified for some reason as Android 4.3.
Of the build versions mentioned above, we spotted JWR25C on the Galaxy Nexus, Nexus 4, Nexus 7 and Nexus 10, while JWR24B was seen on the Galaxy Nexus and Nexus 4. Build number JWR29/JWR29B has been seen on the Nexus 4.
After digging through the virtual dirt, we found out that visits from these Nexus devices running these Android 4.3 variants were registered in the last week of April, hitting as early as April 29 and coming from a variety of locations, including Google’s Mountain View home in California, other California-based locations, but also London, UK and India.
The screenshot above also shows two other non-Nexus devices running other Android 4.3 versions. One of them is listed as the Huawei U8819 (a model number awfully similar to the Huawei Ascend G300 U8818/U8815) running Android 4.3.3, while the other one is the ADR8995 4G (known to the public as the Pantech Breakout) running Android 4.3.1 (which is interestingly, and probably mistakenly, dubbed as Key Lime Pie).
