If Eldar Murtazin is to be believed, the Samsung Galaxy S III will come in both dual-core and quad-core iterations and feature 12-megapixel cameras. What's more, the phones are said to run Android 4.0 with a "tweaked" UI, likely Samsung's TouchWiz, and feature an HD display. Assuming the latter is true, we might expect to see a similar screen size (4.5 inches and above) and resolution (1,280x720 pixels) as the Galaxy Nexus.
There is mention as to how much memory or storage is included in the next-generation smartphone, but rumors have been floating around for some time. With numbers that range from as low as 1GB RAM and 16GB storage to as outlandish as 2GB RAM and 64GB storage, it's tough to say for sure.
