The Sensation has a unibody construction, meaning the frame is milled out of one solid piece of metal. You can see some machining marks inside the metal case from where no doubt CNC was used to remove material in the right places. As a result, the Sensation doesn’t have a battery cover that snaps onto the back so much as the phone itself snaps into one monolithic case. 

There’s a spring loaded button at the bottom of the Sensation which presses in, at which point the device releases and can be lifted slightly. A downward tug then pulls the Sensation out of its metal exoskeleton.

To reassemble the Sensation, the front speaker, camera, and LED all insert into a lip, and then press down. With the phone disassembled, you can get at the battery, SIM slot, and microSD card.

There's a bit of an opportunity for dirt to creep in here, but only when the phone is open like this. The only place that things are a bit sensitive are the top front where the front facing camera, speaker, and LED light sit - you can easily get dust in here that will affect the camera. 

While we're talking about the LED notifications light, I should note that it still is located behind the speaker grille, this time at the far right next to the camera. This was something a lot of people complained about on the Desire HD, and I can understand why - it simply isn't as visible this way because the grille is recessed. 

The back camera however remedies the problem we've talked about with a few other HTC devices that have snap on rear covers. There's no longer a removable plastic layer that's part of the battery cover on the Sensation, and as a result no opportunity for dust, grime, fingerprints to scatter light and create glare and haze. The circular camera cutout allows the module to stick through slightly. 

The volume buttons on the Sensation are thankfully very communicative and protrude enough to be located easily. I'm a bit less enthused with the power button, which is a bit small, and sits flush on our review unit. HTC also put the microUSB port on the bottom left side of the phone, another one of those love it or hate it things. 

I'm impressed with how well the Sensation sits inside this cage, it doesn't rattle or move around at all inside, which is quite a testament. The only evidence that the Sensation literally isn't one solid piece is a tiny gap at the top where the display meets the speaker grille. 

Of course the Sensation needs RF windows for antennas (this is a cell phone after all), so unfortunately the entire backside can’t be metal. Apple isn’t the only one getting creative with where it hides antennas, as HTC patterns them onto the back of the two discrete plastic parts inserted into the metal structure. This is very similar to how the HTC Thunderbolt uses its back case as an antenna, and likewise to how the Desire HD used its battery and SIM slot covers. 

With the Sensation removed from its exoskeleton, you can see the four separate gold antenna connectors which mate up with gold pins on the rear of the device. It doesn't affect the majority of smartphone shoppers, but HTC has also chosen to go with Torx #5 screws throughout the Sensation. I didn't take it apart, but just thought it worth mentioning for those of you interested in ease of disassembly.

We should also talk about the display on the Sensation, starting with the display's slightly concave lip. Curved glass seems to be a trend lately, and the Sensation does something unique on the Sensation that I wish everyone did. 

Instead of leaving the display completely a completely flat piece of glass, HTC created a top glass layer that is slightly curved at the edges, thus recessing the main display and interaction area by just shy of a millimeter. It's a very subtle concave structure. As a result, the display doesn't rest completely coplanar with flat surfaces when you placed face down, and is far less likely to get scratched. It’s just a small detail that shows HTC has been paying attention to the subtle things when it comes to designing its hardware.

    Yeah, nvidia need a slap for leaving h264 main/high out of their hardware codec in Tegra 2 and not bothering to add Neon.

    Cardinal sin!

    DICE player allowed you to play 1080p mkv on the Sensation. I've even played Blu-ray rips, though not at really high bitrates (20mbps I believe). Reply

    S2 will play 1080 Adobe Flash video. Sensation will get up to 720, but G2X and Optimus only play 480p. Reply

    I've been recommending sensation over GSII just so that i will be the only one with GSII...

    But anyone that has tried both devices have said GSII is noticeably quicker that includes the Tmobile employee that was letting me test drive the device while she played with mine

    There are 2 negative points regarding the Sensation which keep me from buying the phone:

    1. As you mentioned, the space between the display and the case. Many users already got dirt and dust under their display.
    2. Choppy performance. It's a dualcore phone and the browser is still very choppy - I can't live with that. I don't buy a DC phone just to see choppy browsing.

    At the same time, other high end phones like the Galaxy S2 suffer from huge problems too. The praised display has huge drawbacks. A yellowish tint and gradient from left to right and huge banding issues. It's very well documented on XDA.
    I expect those things on mediocre phones. But choppy browsing performance despite a DC SoC or problems with the display (be it dirt or just a crappy display) are a no go for a super high end smart phone for me. So I'll probably wait for the next Nexus.

    Try Opera Mobile. Reply

    True, Opera mobile is really smooth, even on my Desire. I'm still somewhat disappointed in the browsing experience on stock Sense. Reply

    That's one of the things I love about Windows Phone 7. The smoothness of the platform, even on older hardware, is amazing. When comparing it with an Android phone back when I purchased (last November) my LG Quantum, and the Android device actually had better hardware, the choppiness was unreal. I would hope that it would be better with these DC phones but it doesn't seem to be the case.

    Nice review guys,wondering why the Samsung Galaxy S wasn't included in any of the benchmarking? Reply
