The biggest physical annoyance is a metal lip that runs around the edge of the phone, meant mostly to help you grip the thing. I appreciate HTC's willingness to act on consumer feedback -- the M8 was a slippery beast sometimes -- but it can feel awkward sometimes when that ridge sticks into the meat of your palms. After the M8's incredibly comfortable river-rock design, little touches like this come off as foreign and even too reactionary.

If anything, "little touches" is the guiding philosophy of the One's 2015 hardware design. The company strove to create a far more premium handset (it really likes comparing the M9 to luxury watches), but the M8 was such a strong foundation that there just wasn't a whole lot that needed to be done. The volume rocker has been split into two separate buttons and the power button has been moved to sit right under them on the M9's right edge. There's (still) a pop-out microSD slot above those. One of the BoomSound speaker grilles up front is a little smaller to accommodate the slightly larger front-facing UltraPixel camera. As far as HTC is concerned, there wasn't much broken physically that needed fixing, and I'm mostly inclined to agree.

Still, there's always something, and in this case it's the squared-off, 20-megapixel camera sitting around the back. Part of the issue is that HTC made the switch in the first place -- by moving the UltraPixel tech up front and plopping a 20-megapixel Sony sensor into the M9, HTC's basically diving back into the Imaging Cold War it's distanced itself from for the last couple of years. That's no great sin by itself, but in my early testing (with non-final software, in fairness), the camera seems noticeably worse than that of the M8. Confused? So was I. Right out of the box, white balance and color temperature seemed inexorably screwy, while shots taken with the last-gen M8 were more accurately exposed. Results from photo shoots in brighter conditions fared a lot better, but here's hoping a few last-minute software tweaks are enough to get that camera into fighting shape.



While we're talking about software and all, there are plenty of changes to behold in the form of Sense Seven. Let's back up for a moment: I've always enjoyed HTC's Sense UIs, but I find it's started to lose its luster as more phone makers take the pared-back approach to their interfaces. The new Sense 7 UI reaches farther than HTC has seemed comfortable going before, but you know what? Those additions wound up being my favorite additions to the fold. BlinkFeed is still back and populated with news from your favorite sources, but now it'll look at factors like your location and past preferences to surface suggestions -- say, where to eat lunch with help from Yelp -- on your lockscreen. Oh, and all of the apps you download go into a Downloads folder up front rather than clutter your home screen(s). Nice touch, people.

More importantly, you can now theme the dickens out of your phone with HTC's blessing. Everything from the wallpaper to the icon set to the keyboard to the launcher itself can be mixed, matched and tweaked to your liking. You'll find a handful of themes available directly from HTC when you fire up the phone, but ultimately HTC wants us all making, sharing and, yes, selling our themes to other design nerds. When spokespeople first told me about theming, I sort of groaned to myself -- after all, it didn't take much to turn a bog-standard Myspace page into an unholy nightmare of clashing design elements. That's not really the case here yet. Scrambling up bits from each official theme looked bad, but not outright terrible, and the best results came when I loaded a pre-made theme and swapped little things like the keyboard and icon sets.



Maybe the biggest question mark here lives in a Sense Home widget that offers quick access to apps it thinks you'll need based on where you are: Home, Work or Out. There's a Suggestions folder that means to highlight new apps to download by chewing on your usage history. Thing is, HTC hasn't ruled out the possibility of linking up with partners for sponsored suggestions, though, and that's a slippery slope to stand on the edge of.



We'll hold off on our final judgment until we get a review unit in our hands, but HTC really seemed to favor polish over progress this year. Fair enough -- no company can push the envelope in big ways every year. That conservative philosophy seems to have yielded a phone that's really lovely, but it's maybe not as exciting as it could have been. We'll just have to wait and see if that distinction actually means anything to the people considering buying one.
