Samsung’s highly anticipated next-generation flagship smartphone has reportedly been pictured. Dutch mobile blog GSM Helpdesk on Wednesday published what it claims to be an official press photo of the Samsung Galaxy S III, obtained from an unnamed source. The site also reasserts a wide range of specs exclusively reported by BGR over the past few months, including a full HD Super AMOLED display, Android 4.0 with Samsung’s TouchWiz UI and a 1.5GHz quad-core processor. The device pictured is in line with previously leaked renders, though we can now see that Samsung appears to have opted for capacitive hardware buttons in place of the on-screen navigation buttons seen in other Android 4.0 builds. A potential date for Samsung’s announcement has been reaffirmed as well; the weather in London and the Unpacked Event calendar entry pictured on the home screen point to a May 22nd press conference in London.
