I experienced reliably good Sprint WiMax 4G coverage in San Francisco. I had a strong 4G signal pretty much everywhere I went in the city. Sprint's 4G network paired with the Samsung Exynos dual-core processor makes for some excellent Web browsing, too. Over 4G, PCWorld.com (the full site) loaded in a speedy 12.1 seconds. Image-heavy site TheBoldItalic.com loaded in 10.1 seconds, and media-heavy ThrasherMagazine.com loaded in 13.6 seconds.

Of course, 4G coverage and signal strength vary depending on where you live in the country and whether your city even offers 4G. We have good 4G coverage in San Francisco; but in our , Sprint had the poorest country-wide coverage.

Call quality over Sprint was very good overall. My friends and family said that they could hear my voice perfectly and described it as sounding natural.

Superb 8-Megapixel Camera

When we reviewed the European version of the Galaxy S II, we were impressed by its 8-megapixel camera. Luckily, Samsung seems not to have changed the sensor for the U.S. versions. The Epic Touch took excellent photos indoors and out. My only complaint is that colors in my indoor photos looked a bit oversaturated. Details were quite sharp and I didn't detect any graininess or pixelation. The shutter speed on the camera was fast enough to capture photos of sports, kids, and other quick-moving subjects. Again, I must lament the lack of a physical shutter button, but the camera's quality makes up for it.
