This week I checked out the, Sprint’s Samsung Galaxy S class phone. If you have already seen the Captivate (AT&T) and the Vibrant (T-Mobile), then you already know a little bit about this phone.
First off, like its siblings, the Epic 4G has a gorgeous screen. That Super AMOLED display is really the cat’s meow. Currently I feel it is the only way one should be watching movies on a phone. Forget your Blackberry (as a BB lover, pains me to say that), forget your iPhone, forget your Evo. If you want to have a little in your pocket, you want a Samsung Galaxy S device, so you want the Epic 4G.
Moving away from talking about the screen (which is pretty hard because it is just so pretty), the Epic 4G is the first and only phone with a slide out keyboard that I think is worth using. I’m not a big fan of slide out keyboard phones, but the Epic 4G does it well, and it was a joy to use.
Overall the is a win! Though it has a slide out keyboard, it isn’t overly thick, or awkward. It has a nice shape, height, and width. This is definitely a phone you should be looking at if you are with Sprint.
Like all other Galaxy S phones, it's all about the screen. The 4-inch Super AMOLED display dominates the front of the Epic 4G, surrounded by an all-black bezel. What makes this device different than its cross-carrier cousins is its unique slide-out keyboard, which packs five rows of backlit goodness. Because of this amenity, the 5.5-ounce Epic 4G weighs more than the Captivate for AT&T (4.5) and the Vibrant for (4.2) ounces. The Epic 4G is also understandably thicker than both of those phones (0.56 inches vs. 0.4 inches). We think this trade-off is worth it for the great typing experience, but you'll definitely notice the extra bulk in your pocket and when holding this device up to your head. On the other hand, the Epic 4G is lighter than the Evo 4G (6 ounces) and the Droid 2 (6 ounces), which also has a slide out keyboard.
For Sprint and Samsung the Super AMOLED screen was so important in this case that the capactive menu buttons beneath the display are blacked out when the screen is off. This treatment gives the phone a more modern appearance than the Evo 4G (whose buttons are always legible) but it sacrifices functionality for style. Overall, though, we prefer the rounded edges of the Epic 4G to the Evo 4G's boxy slate aeshetic, as well as the former's chrome accents.
The right side of the handset houses a small power button up top and a camera launch/shutter key on the bottom right. Up top you'll find the 3.5mm jacks and microUSB port (behind a sliding door), and the left side has a volume rocker. The black plastic back of the phone has specks of silver in it, a nice touch, and it's pretty easy to pop the cover off should you want to access the battery or memory card. On the back there's also a lens for the 5-MP autofocus camera with an LED flash beneath it. What you don't get that the Evo 4G has is an HDMI port and a built-in kickstand
