Samsung's third-generation Galaxy has been the subject of much rumour and speculation. The company recently confirmed that it will be powered by a Exynos 4 Quad processor with improved battery support, and run Google's Android 4.0 Ice Cream Sandwich operating system.
Reports from around the web suggest that it will also feature a 4.8-inch display with a Full HD 1080p resolution and a 16:9 aspect ratio. A 12-megapixel camera and wireless charging have also been rumoured in the past.
Samsung is expected to unveil the Galaxy S3 at its press conference at Earls Court Exhibition Centre in London at 7pm this evening.
