I've got a tendency to be a little long-winded when it comes to device design, so here's the TL;DR if you've got more pressing things to do: The Desire Eye's got personality. It looks like an ice cream sandwich. I love it. Mostly.
Still with me? Right. That ice cream sandwich aesthetic is the first thing you'll notice about the Desire Eye; our review unit is a two-toned affair, with a thick red stripe bisecting the rest of the phone's snow-white body along its edges. Persnickety style mavens might disagree, but I adore the look (in your reviewer's humble opinion, the alternate blue-and-teal version just doesn't stick the landing). The second thing you'll notice is that you've got two identical 13-megapixel camera pods sticking out of the phone's face and rear, each flanked by a two-tone LED flash.
The next thing you'll pick up on: how cumbersome the thing can be. My hands aren't gigantic, but they're not exactly small either, and the Desire Eye seemed thick -- just wide enough to feel awkward whenever I picked it up. In fact, it's not even about how chunky the thing is; with an 8.5mm waistline, it's technically not even as plump as the 2014 Moto X at its widest point. Really, it all boils down to a design issue: Plenty of other well-received phones have similar thicknesses, but their sides and backs curve dramatically to nestle neatly into your hands and imbue the package with an overall sleeker feel. The end result is a phone that feels substantial in spite of its apparent slightness. The Desire Eye is not that phone.
What it is, though, is solid. HTC's crafted a body out of polycarbonate, and the shell that forms the backplate sweeps up over the sides to give it a sturdy -- if relatively light -- feel. On the plus side, the material is sleek enough that you can easily slide the phone out of your tightest jeans pockets, though you might occasionally lose your grip on it like I did. We might not forgive these sins on a flagship, but HTC's Desire line has always been aimed at a more modest market and those flaws seem just a little more forgivable with that in mind. The whole shebang is IPX7-certified too, so it'll withstand dips in up to a meter of water for a half-hour before things really start to get dire. Curiously, though, the micro-SIM and memory card aren't tucked under a battery you pry open with a thumbnail. This is one of those little cost concessions that actually works really well; you'll never have to pry off a flimsy battery cover or scramble for a paper clip to access those all-important bits of plastic. Sorry, lefties: The placement of these slots means the volume rocker, the power button and the dedicated two-stage shutter button all sit on the Eye's right side. We sympathize with your struggle.
Display and sound
Let's not mince words: The Desire Eye is definitely meant to be a mid-range phone, and plenty of nerds will stop reading after they see someone invoke the "m" word. With all that said, the 5.2-inch 1080p IPS display we've got here (which, remember, is a touch larger than the HTC One M8's) is surprisingly easy on the eyes. It's big and spacious. Color reproduction seems vivid without being outright inaccurate and the viewing angles are accommodating even to people sitting at nearly oblique angles. And the kicker? The screen can be terribly bright if you want it to be (eat that, sunlight). With levels cranked up to the maximum, the Desire Eye easily outshines the more premium One M8 and its fancier Super LCD 3 panel. If I had to pick nits, there's the very faint light that bleeds into the picture from the edges of the display, but it's only really apparent if you're looking at dark images in dim spaces. Don't worry about it too much.
As usual, the speakers don't quite live up to the high bar set by the Eye's display. At first glance, there's a decent shot you'd miss the speakers altogether since they're dark and nestled right up against the edges of the screen. They're subtle and well-hidden, but they'll get the job done (and then some) when it comes time to binge on YouTube videos. That's not to say they're nearly as good as the speakers you'll hear on other devices, though: They lack the oomph and depth you'll get out of a One M8, and the sound issuing forth from the stereo pair isn't as downright loud as the iPhone 6's single speaker. Still, the fact that we're getting some separation between channels means most things you'll listen to will still probably draw you in deeper, even if the overall experience isn't as loud or bass-heavy. Plug in some headphones, though, and we're off to the races -- HTC's BoomSound audio tech does a commendable job livening up most things you'll listen to on a regular basis.
HTC fans -- and even people who just casually read this site -- could probably spot the company's Sense interface from a mile away. It's distinctive in its subtlety, a tough act to nail when it comes to laying extra bits on top of beautiful, beautiful stock Android. Anyway, the Desire Eye ships with a Sense-ified version of Android 4.4.4 KitKat, a flavor combination we've run into a few times already. (HTC has said that all of its current phones would get Android 5.0 Lollipop within 90 days as part of its Advantage program, so hopefully the wait won't be too much longer.)
The laundry list of Sense's software niceties include a Do Not Disturb mode that lets you define certain times you want to disable notifications and an Extreme Power Saving Mode that automatically shuts off all but the phone's most vital functions when the battery dips below a certain level. BlinkFeed is still here, and it's still really good at what it does. The elevator pitch, if you haven't already heard it: BlinkFeed lets you customize your own personal news feed, culling content from websites and news sources and pulling pertinent data like calendar entries into a single spot. It's still the most visually different element of HTC's Sense experience, not to mention one of the most useful -- a quick swipe right from the home screen takes you straight into your customized news feed, perfect for when you're standing around with a few moments to kill.
The rest of the interface is as familiar and as unobtrusive as it's always been... for the most part, anyway. AT&T being AT&T, of course, your eyes will get blasted by a full suite of preloaded carrier apps and shortcuts that can easily be deleted or disabled during a quick trip into the device's settings. Don't feel like traipsing into the depths of your device? You won't have to, technically -- HTC's app launcher lets you completely hide certain apps from view, though for the sake of the relatively paltry 16GB of storage, you're better off axing them completely.
There aren't any UltraPixels here, folks. When it came time to cobble together the Desire Eye, HTC didn't go nuts trying to reinvent the sensor -- instead, it picked a pair of almost identical 13-megapixel cameras and plopped 'em right in there (more on that later). You'd think that a phone so clearly keen on photography would pack a barnburner of a sensor (or in this case, two barnburners). Alas, while the cameras here definitely aren't bad, anyone looking for truly excellent performance is going to walk away a little disappointed.
Let's start with that rear shooter, shall we? Resolution aside, it's got an f/2.0 aperture to suck in as many photons as possible, and a 28mm lens perched in front of the sensor. Just like every other smartphone camera out there, the photos I captured using the Desire Eye's rear-facer were mostly well-saturated when the sun or a room's lighting were playing nice, but the situation quickly gets hairy as things get dim. Typical, no? It doesn't help that most of the pictures I took outdoors seemed a little dimmer and less vivid than reality by default -- it took a few trips into the HTC Camera app's settings to fire up HDR mode or tweak the exposure and ISO to my liking. It never felt like the Desire Eye took too long to adjust focus as I bounded from subject to subject; on average it took just under two seconds to figure out what it was looking at. That'll seem downright glacial if you're used to the sub-second focus times of the One M8 and the LG G3, but in practice it's less of an issue than you might think. If this camera has committed any great sin, it's that it doesn't excite; it's not great, but it's not bad either. Most of the time I wouldn't even get worked up about it, but when a company tries to play up a camera when it tries to sell a phone, I can't help but expect more than just the status quo.
