The Samsung Galaxy S4 I9507, which is yet to be officially announced by the company, has first appeared in the EXIF data of an image that was found somewhere on Picasa. The data showed that the image was taken in 10 megapixels, but that doesn't necessarily mean the GS4 I9507 will have a 10MP camera. The image could have simply been taken in a 16:9 format, in lower resolution, or something else.
While this piece of data shouldn't really be considered a very trustful source, that same model number has later popped up in the GFXBench database, where the accompanying data detailed the handset as one that is featuring a Snapdragon 600 chip (with Adreno 320 GPU), 1080x1920-pixel screen and LTE connectivity. When it comes to the benchmark results themselves, they seem to be quite similar to those achieved by the 'regular' versions of the GS4 - the I9500 and I9505.
Finally, User Agent Profile data (hosted on Samsung Mobile's own website) for the GS4 I9507 has also surfaced, confirming the 1080x1920 resolution screen, but not much else. The UA profile contains entries about ARM11 CPU, but since that's a very old technology, we don't think it'll have anything to do with the final product.
Some sources are speculating that the I9507 might be a dual-SIM or regional-specific version of the Snapdragon 800-powered I9506, but it doesn't seem that we have enough evidence to think so. We can hope that the higher model number could be an indication of an upcoming GS4 version that's featuring an even more powerful processor than the Snapdragon 800, but that should also be considered pure speculation for now.
