Before I actually get to the hinges, let me say that I’m a fan of HTC’s design and engineering team. They put out some of the most consistently well engineered mobile devices, and I’m struggling to remember the last time I was disappointed by the design or build quality of an HTC phone. Whether Windows Mobile or Android, HTC has generally been on top as far as build quality and design goes. Just look at the EVO, the HD2, the Incredible, the Nexus One, or the new Desire HD to see what I mean.

Gallery: T-Mobile G2

For the most part, the G2 is pretty great and up to the same HTC standard. The top half of the device is mostly constructed of an anodized aluminum, with the bottom edge being done in soft touch plastic. The same soft touch plastic is the primary material for the bottom half of the device, surrounding the keyboard and battery cover. The battery cover itself is rendered in brushed aluminum, with HTC and G2 logos etched in. The entire package is very solid as expected, and the level of attention to detail paid here is so high that there’s even a spring-loaded release switch for the battery door. This is stuff that normal handset makers don’t even dream about (Samsung, I’m looking straight at you. I was certain that the Fascinate’s back cover was going to snap the one time I tried to take it off). HTC's usual attention to design makes that “Z” hinge all the more perplexing.

Note the usage of the word hinge. Most landscape QWERTY devices use a slider - pretty simple stuff, just a set of rails on the back side of the screen and a set of protruding runners above the keyboard. You might find a spring attached to make the motion of the screen smoother and ensure the screen stays open or closed, though this depends on how much space there is (for example, the super-thin Droid and Droid 2 forgo the spring-loaded mechanism). Now the G1 had a funky, curved hinge that basically acted as a slider, since the motion was in the same plane as the screen (there was also an arced track/runner system on the left side of the device.) This time around though, HTC has one upped themselves and made that hinge act perpendicularly to the plane of the screen.

What this means is that instead of a curved slider like the G1, the G2’s screen actually travels in a semicircular arc in the process of “sliding” up, hoisting itself above the body and then coming back down to reveal the keyboard. It’s a pretty neat trick, seeing the screen a centimeter above the body, until it hits you - the only thing holding the screen and the body together at that point are three plastic posts that are about 1 mm^2 in cross sectional area, and an exposed ribbon cable. Oh God.

What makes this even more concerning is that HTC is having some early run quality control issues with the G2. Among the laundry list of common issues is that on some devices, the hinges are loose. For example, if one were to hold the phone upside down, the screen would fall open. As luck would have it, my unit was one of them. The looseness of the springs and the overall lifelessness of the mechanism probably is contributing to my paranoia about the hinges, but I have played with another G2 that did have properly working hinges and while the hinge did feel more robust, it certainly did not feel sturdy. I’d be interested to see how much fatigue testing HTC did before finalizing this hinge design for production, since the “pop hinge” (their term, not mine) seems like a pretty large Achilles’ heel for an otherwise excellent design.

    Sorry, I wasn't criticizing the article. I really like that AT phone reviewers use the said phone for a few weeks before posting their full write-up. It shows exceptional polish and class on their part.

    Like you mentioned, this "preview" has about the same amount/quality of information that a typical "review" provides.

    Umm, sometimes the stuff in plain sight is the hardest to spot :) Sorry from me.

    6Mbps down and 1Mbps up is what I get indoor with my HTC Hero (which is only 7.2 Mbps HSDPA) here in Canada. That doesn't sounds like HSPA+ speeds at all.
  • mino - Thursday, October 7, 2010 - link

    Yeah, And I get barely .5 Mbps from my Huawei 3G router with external antenna. That is explicitly on HSPA+.

    At the same time I get extremely good .2 Mbps from EDGE on the same spot cause the 2G tower is a bit closer...

    Basically, unless testing at the same time, during night, during clear weather, in the same setting, at the most optimal position, any such comparison is moot.
    There are just too many unaccounted variables.
  • zorxd - Thursday, October 7, 2010 - link

    Still, 6 Mbps is below 7.2 so it is not a proof that HSPA+ is even being used.

    Using my Sprint HTC Touch Diamond and booting into Android 2.2, the app reads after 5 tests:

    136-710 kbps down
    83-160 kbps up
    140-190 ms ping

    Using WM6.5 and mobile speed test web page, I can get 1,300 kbps down, 800 kbps up, and 130 ping. WM6.5 is a bit easier for my meak hardware to run than Froyo.

    That's inside with a signal moving between 0 and 1 bar. It may seem pathetic, but it's fast enough to stream Youtube.

    .5/.2 Mbps seems "offly" low. Are you sure it's not MBps?
  • sprockkets - Thursday, October 7, 2010 - link

    Not on EDGE :)
  • mino - Thursday, October 7, 2010 - link

    .5 is on the last straws of 3G signal & not very bad weather
    .2 is on 1800MHz 2G network with reasonable signal quality

    Why I mentioned is that there encoding and band used is only one of the variables. And in most cases not the most important one.

    It does come preloaded with SWYPE. I personally use it when I only have one hand free and can't flip the keyboard out.

    I think it is at least worth mentioning.
