A pre-order page for the Samsung Galaxy S III has apparently gone live in advance of the smartphone’s May 3 debut, with Amazon Germany pulling the trigger early. Priced at €599 ($792) unlocked and SIM-free, and sold direct from the retailer rather than a third-party marketplace seller, the phone apparently has a 4.7-inch Super AMOLED display and a 12-megapixel camera.

It’s also listed as having 16GB of internal memory and a microSD card slot to augment that, along with an LED flash. OS is Android 4.0 Ice Cream Sandwich. However, there’s no image to confirm Samsung’s much-rumored aesthetic changes.

Those specs in partially match up with those of the leaked prototype caught on video in Vietnam yesterday, but with some key differences. The prototype had, it was estimated, a smaller screen than the 4.65-inch Galaxy Nexus, something Amazon says is untrue of the production model, which would be larger.

Meanwhile, the Amazon listing apparently sides with early talk of a 12-megapixel camera, whereas the prototype had an 8-megapixel camera. That could well be down to the age of the leaked handset: it dated back to December 2011, according to labeling spotted on the device, and as such Samsung could have upgraded its camera plans since then.

Either way, there’s not long to go to find out for sure. Samsung will officially unveil the Galaxy S III in London on May 3, and Android Community will be there to bring back all the details!
