Not too long ago, things were pretty simple in T-Mobile's Android land. For us (the nerds, geeks, power users, early adopters, and other misbegotten social deviants) there was the G series of phones with plain Android, culminating recently with LG's delightful G2x. If you wanted to buy your mom an Android smartphone, you'd point her at the myTouch series of handsets with custom HTC Sense-based skins, like last winter's myTouch 4G. Life got a bit more complicated with the introduction of LG's Optimus T, Samsung's Galaxy S 4G, and other devices that don't neatly fit into the carrier's grand branding scheme. Well, fear not! T-Mobile and HTC went ahead and refreshed last summer's lovely myTouch 3G Slide with a dash of dual-core tech lifted right from the HTC's Sensation flagship and a bespoke 8 megapixel shooter said to be "the most advanced camera of any smartphone". Those are fighting words... so does the myTouch 4G Slide (as it's called) beat the likes of Samsung's Galaxy S II, Sony Ericsson's Xperia Arc, and Nokia's N8 in terms of imaging performance? Is the sliding keyboard as pleasant to use as its predecessor? And most importantly, is this your mom's next phone? Read on for our full review.
T-Mobile myTouch 4G Slide review
Hardware
It's easy to mistake the myTouch 4G Slide for the myTouch 4G when seeing it for the the first time. Both phones look almost identical from the front -- at 3.7 inches, the Slide's glass-covered WVGA capacitive touchscreen is only 0.1 inches smaller than its slate cousin. It features the same baroque earpiece and chrome rim around the screen. Like other myTouch devices, it comes with a row of four bona fide physical buttons (home, menu, back, and "Genius") plus an oh-so-retro optical trackpad above the signature chin. The silver ring around the front-facing camera lives on, along with the myTouch logo and notification LED. Flip the Slide over and it's a much more cohesive design. Gone is the myTouch 4G's mishmash of surfaces and textures, replaced instead by a silver accent along the edges of handset and a matte, off-white "khaki" battery door / back cover with a large, slick, machined aluminum pod incorporating the camera (the phone is also available in a more austere gunmetal and black color scheme). The words "8.0 MEGAPIXEL CAMERA" are prominently etched on the pod, which is flanked by a dual LED flash and a secondary microphone. A molded HTC logo and the speaker grille populate the other half of the back. On the sides of the Slide you'll find a standard 3.5 mm headphone jack and power / lock key on top, a volume rocker and micro-USB connector on the left, the primary microphone, a slot to pry the cover, plus a lanyard attachment at the bottom, and finally, a dedicated two-stage camera button on the right.
The myTouch 4G Slide is as pleasant to handle as it is to look at. It's a solid, well-made device with a heft that inspires confidence despite the extensive use of plastics. Both the weight (184g / 6.5oz) and thickness (13.2mm / 0.52in) are on par with other sliders (HTC's G2 comes to mind). Still, it can feel somewhat bulky if you're accustomed to slates like the myTouch 4G. Pop the back cover and you're greeted by a 1520mAh battery that's also compatible with the Sensation, SIM slot, and microSD card reader (a 8GB card is supplied). There's an interesting design touch here: the camera is mounted in a machined aluminum cylinder which is partially anodized in a beautiful shade of apple green. Sadly this is most obvious when the battery door is removed, and will likely go unnoticed by the casual observer. Sliding the handset open reveals a staggered four-row QWERTY keyboard with black keys on a silver faux-aluminum background. While the mechanism (which is not spring loaded) is adequately smooth and sturdy, the keys themselves feel mushy compared to the myTouch 3G Slide. We'd have preferred keys with better defined tactile feedback. The other problem is the backlight, which only turns on when it's pitch dark, making it difficult to read the keys in low light. In practice, we ended up using the onscreen virtual keyboard (we installed SwiftKey X) more often than the physical QWERTY keyboard. So if you're considering the Slide for its keyboard, try before you buy -- you've been warned.
Under the hood, the myTouch 4G Slide is almost a dead ringer for the Sensation. You'll find the same Qualcomm MSM8260 Snapdragon SoC with its 1.2GHz dual-core CPU and Adreno 220 GPU, 768MB RAM, and a combination quadband GSM / EDGE plus tri-band UMTS / HSPA+ "4G" radio -- the latter supporting Band IV (AWS) and Bands I / VII (world). Other specs include the usual suspects: at least half the sensors known to human kind (compass, gyroscope, accelerometer, proximity, and ambient light) along with a full complement of radios (WiFi b/g/n, Bluetooth 3.0+EDR, GPS / AGPS, and FM). The Slide lacks a qHD display, making due instead with a more pedestrian 3.7-inch WVGA (800x480 pixels) Super LCD panel. We'd gloss over this if the screen was of the same caliber as HTC's Incredible 2, but the Slide's display quality is just average at best. The screen looks fine indoors, but falls apart in direct sunlight, and generally exhibits mediocre contrast and viewing angles.
Calls sounded acceptable, and we didn't have any issues with reception, but our tests showed more variability in HSPA+ performance than other devices on T-Mobile's network. It's nothing to be concerned about, but it's worth a mention. As for battery life, we recorded a rather paltry four hours and 43 minutes on our newly minted battery rundown test (which basically involves starting with a full charge and looping the same video until the phone shuts down). Our battery usage test -- which attempts to replicate a light day's use (making a few minutes' worth of calls, reading email, checking social networks, and occasionally responding, texting, surfing the web, or uploading some pictures) with plenty of idle time -- scored 15 hours and 35 minutes, which puts the myTouch 4G Slide somewhere in the middle of the Android pack. One time, we even managed to squeeze a full 24 hours from the battery, but that included six hours of sleep. Just don't leave your charger at home, OK?
Camera
Judging from all the buzz, T-Mobile and HTC are very proud of the my Touch 4G Slide's camera. Is it justified? Yes, absolutely. We'd rank the Slide's camera at number three in the current crop of cameraphones, beating devices like the iPhone 4 and Xperia Arc, trailing closely behind the second place Galaxy S II, with the N8 taking the number one spot by a wide margin. Now that we've got that out of the way, let's see what the Slide's camera is capable of, how it shines, and where it falls short. We'd also like to dispel the claim that it's "the most advanced camera of any smartphone" since it mostly combines features already available on other handsets.
T-Mobile myTouch 4G Slide sample shots
What makes the myTouch 4G Slide's camera unique is a combination of custom hardware and software. HTC designed a completely new camera module using a backside-illuminated 8 megapixel sensor combined with a quality 3.69mm 1:2.2 wide-angle autofocus lens. At the time of writing the Slide is the only device in HTC's lineup equipped with this module -- sorry, Sensation owners. You don't have to be a rocket scientist to realize that this camera is a serious piece of kit. The lens opening is massive for a phone and the sensor is extremely sensitive, something that we noticed immediately the first time we shot in low light. The only missing ingredient in this tiger blood recipe is the apparent lack of mechanical shutter, something you'll find on every single one of Nokia's imaging handsets from the N8 all the way back to the legendary N95 (and on Motorola's Droid X, incidentally). While the Slide features a dual-LED flash, it's not being used as an autofocus-assist light (like on the Xperia Arc), and doesn't hold a candle to the N8's xenon unit. That being said, we're pretty excited about the dedicated two-stage machined aluminum shutter key, which feels wonderful and provides just the right amount of resistance -- it's better than the N8's. Of course, if you prefer leaving fingerprints all over the viewfinder the camera also includes touch-to-focus along with an onscreen shutter key.
It's by using special software that the myTouch 4G Slide's camera really stands out. The premise is simple: pull out the phone, press the camera button to activate the app (à la Windows Phone), and press it again to take a shot -- bypass the lock screen, collect quality photos, don't go to jail. It's not the first cameraphone that's easy to use (the iPhone 4 is a fast, intuitive, and confident shooter as well), but T-Mobile and HTC wanted to bring the dedicated point-and-shoot digital camera experience to the smartphone, and that's what the Slide delivers most of the time. To achieve this, it uses tricks like continuous autofocus and zero shutter lag (wherein the camera is continuously sampling images and storing them in a circular buffer in order to minimize the delay between pressing / tapping the shutter key and capturing the moment). Unfortunately, while the concept is sound, the implementation is far from perfect. The Slide also provides easy access to scene modes, unlike other cameraphones which tend to bury the setting somewhere deep within the UI -- we're looking at you, N8 and Galaxy S II. As such, the camera features a simple interface with four onscreen buttons to switch between stills and video, select between the front and the back camera, control the flash, and change scene modes as follows:
Auto, which detects and adjusts settings to achieve the best results in most situations. This actually works quite well.
SweepShot, a panorama mode similar to what's available on most Samsung and Motorola handsets. The Slide stitches fewer images together but the resulting panoramas, while shorter, are of higher resolution.

ClearShot HDR, a high dynamic range mode similar to what's available on the iPhone 4. There's a noticeable loss of detail in this mode, even when holding the camera still.

BurstShot, which takes five pictures in rapid succession. It's similar to the BestPic feature that was available a few years ago on Sony Ericsson's K850i.

Night, which optimizes settings for night shots.

Action, a shutter priority mode which adjusts settings for capturing moving subjects.
Macro, which optimizes settings for close-up shots.
Portrait, a shallow depth of field mode for portraits. This allows you to specify the diameter and position of a circular area on the viewfinder outside which the picture will be artificially blurred. It's similar to Instagram's tilt-shift feature on the iPhone, but not nearly as polished. There's no gradient between the area that's in focus and the outside that's blurred, just a sharp transition.
Manual, which provides the following settings (among others) via the menu key: timer, color effects (black & white, sepia, etc...), exposure, white balance, ISO, resolution, review duration, and geo-tagging, face / smile / blink detection.
There's no doubt that the myTouch 4G Slide takes beautiful pictures. Still, as we mentioned above, the Galaxy S II usually performs better and the N8 still plays in a league of its own. The Slide manages to gather a lot of information, but that's no match for the massive amounts of detail captured through the N8's impeccable Zeiss optics. It also exhibits more noise in normal light than the Galaxy S II, despite both phones using similarly sensitive sensors. We didn't experience any problems with exposure but white balance was sometimes a little off. We also noticed what looks like chroma aberrations or JPEG compression artifacts in shots. Low light performance is impressive -- like the N8, the Slide preserves detail at the expense of some noise, thus leaving the door open for post-processing. In addition to the above gallery, here is a ZIP file containing the original photos along with matching samples taken with the N8, Galaxy S II, Xperia Arc, and Canon's s95.
The myTouch 4G Slide captures 1080p (HD) video at 30fps with initial autofocus and touch-to-focus functionality. Audio is recorded in mono using what sounds like a less than stellar microphone. The resulting videos are reasonably sharp and smooth, but we noticed some dropped frame here and there, something that's rather unexpected for a dual-core handset. It looks like the Slide's camera was optimized for stills, and while video recording is definitely serviceable, it's not this device's forte. Hopefully these issues will be addressed in a future software update, along with the introduction of continuous autofocus and stereo sound.
Software
We were pleasantly surprised to discover that the myTouch 4G Slide not only ships with Gingerbread out of the gate, but comes with one of the most recent versions (Android 2.3.4). Like many of HTC's recent Android devices, it runs Sense 3.0, something that we'd normally be moaning and groaning about, yet somehow really fits here. The Slide follows in the footsteps of the other myTouch handsets by using a customized version of HTC's UI that suits it perfectly -- especially when you consider T-Mobile's target audience (the first-time smartphone buyer). Some things are missing compared to "stock" Sense 3.0, such as the ability to place four shortcuts right on the lock screen, but T-Mobile chose to add some potentially useful features like group texting (powered by Bobsled) and the aforementioned Genius button (courtesy of Nuance), which adds full voice control to the phone. Sadly, there's nothing smart about the Genius button -- it looks impressive on paper but works poorly in practice.
In terms of perceived performance, the myTouch 4G Slide just doesn't live up to its dual-core pedigree. It's certainly no slouch, but it's no match for the Sensation, despite having to render 35 percent fewer pixels -- in fact, even our single-core Nexus S feels snappier. Our benchmarks partially confirm these impressions, with slightly lower scores than its sibling for Quadrant (1800 vs. 2000) and for Linpack (43 vs. 47 MFLOPS for single-thread). Linpack (multi-thread) returned 57 MFLOPS, Nenamark 41fps, Nenamark2 24.7fps, Neocore 59fps, and Sunspider completed in 4817ms (when it worked). Other than the lackluster Quadrant results (and occasional problems running Sunspider), these numbers are in line with what we've observed on several other dual-core smartphones. Still, there's no denying that there's a price to pay for T-Mobile and HTC's UI customizations. The Galaxy S II, which features a lighter skin (TouchWiz) but similar specs, just runs circles around the Slide.
Like most carrier-sanctioned smartphones, the myTouch 4G Slide includes some bundled software, and while none of the pre-installed apps can be removed, several of them are actually somewhat useful. Beyond HTC's Sense apps (such as Friend Stream), you'll find Adobe Reader, Bejeweled 2 (PopCap's popular game), Netflix, Polaris Office, Slacker Radio, T-Mobile TV (for carrier-billed live and on-demand TV), TeleNav, Qik Video Chat, and Zinio Reader. Other familiar apps include the Swype keyboard, WiFi calling, and Screen Share (for DLNA support). T-Mobile rounds things off with its in-house My Account, My Device, AppPack, KidZone, Highlight, and T-Mobile Mail apps. It's worth noting that for some reason the music, video, FM radio, and Screen Share apps must be launched via something called Media Room in the app tray -- but otherwise there are no surprises here.
Wrap up
The myTouch 4G Slide is certainly a worthy contender in the race for best cameraphone, but it takes more than hardware and software wizardry to make "the most advanced camera of any smartphone." When it comes to mobile photography, Nokia still reigns supreme with the N8 (which is a far better shooter than it is a phone), and Samsung continues to flex its imaging muscle with the Galaxy S II. It's surprising that despite packing the same processor and battery as HTC's Sensation flagship, the Slide performed worse in our speed and endurance tests. There's also room for improvement in the display and keyboard departments, which don't quite live up to our standards. Ultimately though, none of this really matters -- the Slide is pleasant and easy to use, looks and feels great, and takes gorgeous pictures. As such, your mom won't be disappointed. If you want a qHD display, and can live with less camera, the Sensation is a viable alternative to the Slide for the same $200 (on contract). Still, we think the recently updated G2x remains the best device in T-Mobile's lineup thanks to its top-notch camera and a slightly better display than the Slide for $50 less. Well, what are you waiting for? Go out there and buy your mom a phone already!
