Samsung Galaxy S Blaze 4G (T-Mobile) review:

Samsung Galaxy S Blaze 4G (T-Mobile)

CNET's rug looks good taken from a story above.

The lens will also shoot video in 720p HD. Video quality was pretty good overall, even though the camera had some difficulty adjusting to an abundance of natural light and could fade the picture. My voice recorded fine, but as with all phone cameras, the farther away the subjects are from the mic, the harder they are to hear. Video playback wasn't jerky at all, and the picture was fairly clear, though if you compare this with the crispest 1080p video, you'll definitely notice a difference.

I also tested out the front-facing 1.3-megapixel camera. Photo color was fair, but unsurprisingly pixelated when viewed on the phone or computer screen--not that I mind the natural air-brushed look when I happen to be the subject of said shot and the camera is held so close to my face. The Blaze 4G has 4GB of internal memory, but remember that you can expand up to 32GB after you use the internal memory and the preinstalled 4GB card.

The Blaze 4G could have done better in this standard studio shot.

I tested the Samsung Galaxy S Blaze 4G on T-Mobile's network here in San Francisco. A quad-band GSM phone (850/900/1800/1900MHz), the Blaze 4G also supports HSPA+ 42, T-Mobile's fastest-available network, which can theoretically reach download speeds of 42Mbps.

Call quality was strong overall. To my ears, volume was nice and loud at a medium-low setting and voices sounded natural and warm. There was some low-grade white noise every time the caller spoke, but it didn't mar the conversation, and the line remained otherwise clear.

On their end, my callers also experienced high volume. One was excited by the level, and the other called it "uncomfortably loud." They agreed that my voice sounded true to life, and that the line was clear, but they said that when I spoke, I sounded removed, almost as if I were speaking from a large, echoey room.

Samsung Galaxy S Blaze 4G (T-Mobile) call quality sample Listen now:

Here's a surprise: the speakerphone sounded great from waist level, where I held the phone; it was really loud and clear. Of course there was some echoing because of the speaker on the back of the phone spraying out audio, but the natural quality of the voices came through, and I didn't hear any blips, crackles, or other disruptions. I could comfortably carry on a long conversation over the Blaze 4G's speakerphone if I had to. My callers largely agreed on the points of volume and call clarity, pointing out that it did gain more of that echoey quality.

Internal processing speed and data speed have always been important, but the 4G race heightens the urgency of manufacturer and carriers' effort to sell fast phones. To that end, the Blaze 4G has a zippy 1.5GHz dual-core Qualcomm Snapdragon S3 processor (based on the ARM Cortex-A7, for you processor nerds). It's safe to say that processing lag never seemed to get in my way.

The phone's 4G speeds, on the other hand, presented a few wobbles during my test period. As a reminder, the Blaze 4G operates on T-Mobile's HSPA+ 42 network, a souped-up 3G network that theoretically makes it one of the fastest data phones that T-Mobile can offer. At times, there was noticeable slowness when it came to surfing the Web, streaming video, and loading apps that required an Internet connection to download data. It's still faster than 3G, but if you're aspiring to be the fastest draw in the West, you might want to tone down your expectations. For instance, the diagnostic app reported download speeds ranging from 0.18Mbps to 2, 3, 5, and even 11Mpbs. Upload speeds peaked at a sluggish 1.12Mbps.

One last note on the topic is that every carrier has its weak points when it comes to coverage, so my tests may not sync up with yours if you're in a strong T-Mobile zone.

The Blaze 4G has a 1,750mAh battery that delivers a rated talk time of 7 hours and 9.5 days standby time. We'll continue to test battery drain in-house. FCC tests measured a digital SAR of 0.69 watt per kilogram.

Data speed may not have been as strong as I would have liked when I tested the Samsung Galaxy S Blaze 4G in San Francisco, but I would still recommend the Android smartphone overall. It may not necessarily lead the pack in terms of camera strength or screen size--that honor belongs to phones like the Galaxy S II and the HTC Amaze 4G--but it does offer some really consistent features on a phone that's comfortable in the hand, and $150 is quite reasonable. I would also take data speeds with a grain of salt. I've had no trouble with T-Mobile's phones and network in the past, but the Blaze didn't seem as speedy as promised in my usual haunts. Still, if you don't need a new phone this instant, I might recommend waiting to compare the Blaze with the HTC One S--expected to arrive sometime by late spring--which is an Ice Cream Sandwich phone with an 8-megapixel camera and almost no shutter lag.
