Press images of Samsung’s forthcoming Galaxy S III smartphone have apparently been leaked, according to recent reports. The phone, which is expected to release in April or May, is to be Samsung’s primary competitor for Apple’s upcoming iPhone.

The image was obtained by Dutch site GSM Helpdesk (Google Translation) from a “trusted source” and shows several noteworthy features of the new phone.

Along with the photo, GSM Helpdesk got several details about the new phone, many of which confirm what the rumor mill has been saying. The phone will have a 4.7-inch HD (720×1280) display, with a pixel density of 313 pixels per inch. In case you’re wondering, that’s just a bit above the 300 ppi Steve Jobs defined as a retina display when the iPhone 4 was unveiled in 2010. The device will have a slightly reduced battery life, but like many Android-based phones will have a removable battery. It will be about 8 mm thick and weigh 4.4 ounces. It will also have a 1.5 GHz quad-core processor, 32GB of internal memory, and 1GB of RAM. Whether it will have a microSD slot for memory expansion is not clear, however previous Galaxy S models have not.

GSM Helpdesk’s source predicts a release date of May 22 for the phone.
