Samsung SPH-M610

Though you may think Hollywood celebrities are the group that's most obsessed with being thin, cell phone designers are not far behind. Two years after the Motorola Razr made its debut, the race to make the world's thinnest phone shows few signs of abating, with almost every company out to steal the title. The Samsung SPH-M610 for Sprint PCS is the latest handset to call itself a record-holder, but we won't be surprised if a newer, slimmer, shinier model comes along any day now. Despite our growing desire for a return to big, fat phones we readily admit that the SPH-M610 is an attractive handset with a solid selection of features and satisfying performance. It's $329 if you pay full price, but with a two-year contract it's a more wallet-friendly $179.

The Good

The Samsung SPH-M610 has an attractive design, a fantastic internal display, and admirable performance. It also offers a solid set of features including Bluetooth, a 2-megapixel camera, and EV-DO support.

The Bad

The Samsung SPH-M610's volume was a tad low, its external display is too small, and it lacks stereo speakers. Also the microSD card slot is in a poor location.

The Bottom Line

Despite some minor performance and design issues, the Samsung SPH-M610 is a strong addition to Sprint's lineup and a great choice for a slim phone.

Samsung has a knack for copying a popular design trend and making it better. In the past year, for example, the Samsung BlackJack managed to out-wow the Motorola Q, and the Samsung MM-A900 emerged as a more attractive alternative to the celebrated Razr. With its SPH-M610, Samsung again beats the Razr at its own game. Besides being smaller (3.98 by 2.05 by 0.47 inches) overall than the Razr (3.8 by 2.0 by 0.5 inches) the SPH-M610's curved lines give it a bit more appeal. The black coloring is cool, and though the SPH-M610 is a tad lighter than the Razr, it has a more solid and comfortable feel in the hand.

On the other hand, we didn't love everything about the SPH-M610's exterior. The exterior tends to attract finger smudges and the tiny external display (0.8 inches, 96x48 pixels) is much too small for the phone's size. It shows the time, battery life, signal strength and caller ID (where available) but because the screen is monochrome, it doesn't support photo caller ID. We expect more from a phone that has a 2-megapixel camera. The display's brightness level can't be altered, and though the text disappears completely when the backlighting is off, a flick of the volume rocker on the left spine activates it again.

Just above the display is a rotating camera lens that swivels 180 degrees to the rear of the phone. There's no flash, which is too bad, but when the phone is open you can swivel the lens to take self-portraits. The only other feature on the exterior of the phone is a covered headset jack/charger port (you can use only one at a time) on the right spine. Samsung managed to slip a microSD card slot into the SPH-M610 but we didn't like its placement at all. Not only is it behind the battery cover but you also need to remove the battery to pry out the card.

The SPH-M610's memory card slot is inconveniently located.

The SPH-M610's internal TFT (thin film transistor) display is stunning to say the least. We love its large size (2.2 inches, 240x320) and 262,000-color resolution. Colors, graphics, text, and images were very easy on the eyes, and the simple but efficient menus (available in a few styles) were a cinch to use. You can change the backlighting time and the dialing font style, size, and color, but you can't change the brightness. Like most Samsung displays, the SPH-M610's is difficult to see in direct light.

Slim phones like the SPH-M610 usually suffer a few pitfalls when it comes to their controls. In order to keep the phones as thin as possible, designers resort to perfectly flat keypads. Though we understand why it's done, it makes it difficult to dial by feel. While this is true for the SPH-M610, we like that its keys are covered in a tactile material that makes them less slippery than keys on other trim handsets. They're fairly spacious as well, and are brightly backlit.

For navigation purposes, the SPH-M610 has a large four-way toggle with a central OK button that opens the menu. For quick access to your favorite features, the toggle directions double as shortcuts to four user-defined functions, the right soft key opens the contacts menu, and the left soft key opens a customizable My Favorites menu. Rounding out the navigational array are dedicated camera and speakerphone buttons, a back control, and the traditional Talk and End/power buttons.

The SPH-M610 has a 500-contact phone book with room in each entry for 5 phone numbers, an e-mail address, a Web address, a nickname, and notes. You can save callers to groups or pair them with one of 20 polyphonic or 9 monophonic ring tones. You can assign a photo to contacts as well, but keep in mind that they won't appear on the external display when that person calls. Other features include a vibrate mode, text and multimedia messaging, voice commands including voice dialing, instant messaging, e-mail, a scheduler, a task list, a countdown timer, a memo pad, a world clock, an alarm clock, a calculator, and a voice recorder. On the higher end of the feature scale, the SPH-M610 offers Bluetooth, modem capability, a speakerphone, Sprint's wireless backup service for your contacts, and USB cable support.

As an EV-DO phone, the SPH-M610 offers full support for Sprint's 3G service. You can connect to Sprint's Power Vision steaming video service and its Music Store to download songs to the onboard digital music player. A newer application is Sprint Movies, which delivers full-length pay-per-view movies straight to your phone from studios like Buena Vista, Sony Pictures and Universal Pictures. The SPH-M610 comes with 37MB of internal shared memory, which borders on the low side considering its multimedia prowess. You'd be wise to secure a microSD card (one came with our review model), which in any case is required to download music. Furthermore, you get Sprint's On Demand service for access to a host of information such as news headlines, sports scores, and weather updates personalized for your zip code. And for the perpetually lost, the SPH-M610 includes a trial of Telenav's GPS navigation application. In all, there's an impressive assortment of options.

We like the SPH-M610's rotating camera lens.

The SPH-M610's 2-megapixel camera takes pictures in five resolutions from 1,600x1200 down to 320x240. Other camera features include three quality settings, brightness and white balance controls, a spot metering multishot mode, a self-timer, 5 color effects, 10 fun frames, and a 4X zoom that's not usable at the highest photo resolution. There are also three shutter sounds plus a silent mode. The camcorder records clips in 176x144 resolution with sound; clips meant for multimedia messages are capped at 30 seconds or you can shoot for as long as the available memory will permit. Editing options were similar to the still camera. For easy photo printing, the SPH-M610 supports PictBridge technology for transferring images directly to a printer. In our tests, photo quality was good but not great. Colors were sharp and there was enough light, but unless we held the camera perfectly still (which was difficult to do) images tended to be blurry.

The SPH-M610 had decent image quality.

You can personalize the SPH-M610 with a variety of screensavers, color themes, clock styles, alert sounds, and greetings. If you want more options you can download them from Sprint. For play time there are demo versions of five Java (J2ME) titles: Brain Juice, Diner Dash, Midnight Bowling, Pac-Man and Tetris. It's too bad Sprint doesn't include at least one full title.

We tested the dual-band (CDMA 800/1900; EV-DO) in San Francisco using Sprint's service. Call quality was admirable with great voice clarity and almost no static. Though they could tell we were using a cell phone, callers said we sounded good, and they had no trouble hearing us. On the other hand, volume tended to be somewhat low; users with hearing impairments should try the SPH-M610 before they buy. Speakerphone quality was somewhat diminished--there was some fuzziness, and callers had more trouble hearing us--but it was decent overall. Bluetooth headset calls produced a similar experience. On the reception side we had no trouble getting a signal, and EV-DO coverage was strong. Web browsing was zippy, and songs downloaded in less than a minute.

Music quality was decent overall despite being bass-heavy at times. Yet we can't grasp why all music-centric phones don't offer stereo speakers. As a result, the volume level is rather low, so we suggest using the included wired stereo headset. In addition, Samsung uses a proprietary plug so you can't use your own headset unless you have an adapter. Video quality was quite good, the best we've seen on a Sprint 3G phone in quite a while. Though the overall picture was small for the display's overall size, there was little pixilation and voices matched the speakers' mouths. Also, the video never froze or paused for rebuffering. That said, our eyes grew tired after watching such a small display for too long, and we can't imagine viewing a full-length film.

The Samsung SPH-M610 has a rated talk time battery life of 3.5 hours, but it has a tested talk time of 3 hours and 35 minutes. According to FCC radiation tests the SPH-M610 has a digital SAR rating of 1.09 watts per kilogram.
