Samsung unveiled yet another new device this week in the Galaxy S Duo, a device which is targeted at busy folk that need two SIM cards on the go at once without sacrificing hardware quality. To get a better idea of just how good the Galaxy S Duos is we've decided to hold it up to the most discriminating yardstick around at the moment, the Samsung Galaxy S3. Will the Galaxy S Duos be able to keep up with its lightning quick brother? We aim to find out! Samsung's Galaxy S Duos features a 4-inch TFT display which operates at a resolution of 480 x 800 and sports a pixel density of 233PPI. We can expect the screen to be both responsive and high quality, judging by Samsung's previous, but we don't expect it to hold a candle to the company's AMOLED and Super AMOLED offerings.
