Samsung has a number of new devices on hand at this year’s Mobile World Congress, and one of them was the Galaxy S Blaze 4G set to launch on T-Mobile later this year. We got a chance to check out the Blaze 4G, and we left relatively unimpressed. To be fair, the Blaze is a lightning-fast smartphone on par with a number of recent additions to Samsung’s Galaxy line, but it’s hard to get excited over a phone that is only a modest upgrade compared to T-Mobile’s current Galaxy S II. The Blaze 4G features a 1.5Ghz Qualcomm Snapdragon chip, a 4-inch Super AMOLED screen, a 5-megapixel camera and Android 2.3.6 Gingerbread. It’s certainly a solid phone but with HTC’s One S heading to T-Mobile in April and Samsung’s full-HD Galaxy S III on the way as well, T-Mobile subscribers looking for the latest and greatest may want to sit tight and wait another month or so. The Samsung Galaxy S Blaze 4G launches in March for $149.99 on contract, and our hands-on photos of the handset follow below.
