Nokia Oro is covered with 18ct gold on the outside, tinged with Symbian regret inside

0 comments
Nokia has just unveiled a strange new beast of a smartphone. Internally, it's your good old C7 -- 3.5-inch AMOLED screen, 720p video recording, 8 megapixel camera, a pentaband radio, and Symbian as your zombie OS -- but externally it's taken on a lick of gold paint and a rear cover made of real leather. The price for a phone built quite so luxuriously is said to be upwards of €800 ($1,126) before taxes and subsidies and launch is expected in Q3 in select countries across Europe and Asia. Russia in particular is called out as a successful market for such "premium" phones, with Nokia's Gabriel Speratti, General Manager for its operations in the country, explaining that:
"We have a large number of users who are looking for products with a build quality and superior materials that attest to their success and social standing. In some areas, possession of such premium products is the passport to being taken seriously."
We have to agree, owning a phone like this will certainly have an effect on your social life, we're just not so sure it'll be a positive one.

Galaxy S II and Galaxy S screens compared at the subpixel level (video)

0 comments


One Galaxy S II review not enough for you? Hey, we understand, a dual-core phone deserves at least two goes through the Engadget test chambers. Today marks the publication of our Engadget Spanish analysis, which, among other things, compares the GSII against its forebear, the Galaxy S, at the subpixel level. Yes, we've got video capturing the improvement Samsung has made in its new Real-Stripe (RGB) pixel arrangement on the Galaxy S II's Super AMOLED Plus display over the older, less awesome PenTile RGBG layout of the Plus-deprived Super AMOLED panel. You can see it after the break or dive into the source link for a more comprehensive comparison. Non-Spanish speakers will want to jump to the 1:40 mark in the vid for all the microscopic action.

Samsung's foldable AMOLED display: no creases, even after 100,000 tries

0 comments
Samsung demoed some fascinating AMOLEDs at this year's CES, including 4.5-inch flexible and 19-inch transparent displays -- neither of which, sadly, will reach the market any time soon. But the innovation train keeps on rolling, and Sammy's Advanced Institute of Technology now has a prototype foldable display, which may or may not be the same reference design spotted at FPD 2008. Its two panels have a closing radius of only 1mm, meaning they practically touch when closed, yet show no visible crease when opened. In fact, the developers performed 100,000 folding-unfolding cycles to test the junction; the negligible 6% decrease in brightness was invisible to the human eye. They used commercially-available silicone rubber to achieve that seamless look, and the prototype featured a protective glass cover which could also function as a touchscreen. Obviously there's a market for touchscreens you can fold up and put in your pocket; here's hoping Samsung can make them available sooner rather than later.

Samsung Infuse 4G review

0 comments
We're just getting into the swing of spring, flowers blooming and skeeters biting, but already it's been a great year for Samsung -- if we ignore the whole lawsuit thing. Just a few weeks ago the company delivered to us our highest scoring Android phone yet, the Galaxy S II and, while that handset has not appeared on American shores, we were graced with the Droid Charge, which offers LTE speed, strong battery life, and an on-contract price that slightly exceeds its design.

Not so with the company's latest assault on American carriers. It's the Infuse 4G, it's $199 on-contract, and it has a decidedly high-end feel. It even looks a little like the S II -- if you squint. This is its own phone, though, a giant 4.5-inch screen setting it apart from its predecessors, and a giant battery inside giving it plenty of life. But is it really as good as it looks?

Hardware

We were about to pack up the Charge and ship it away when the Infuse 4G arrived in its little orange and white box. While these are very similar phones in a lot of ways they certainly don't feel at all related. The Charge has that pointy chin, cheeky physical buttons, and a little extra junk in the trunk that makes its thoroughly plastic construction feel a wee bit flimsy. The Infuse 4G definitely has a lot of the same DNA coursing through its chassis but in an exterior that's far more chiseled and free of excess anything. It's definitely been hitting the gym.


It's just 8.9mm (.35-inches) thin for the most part, swelling to 9.24mm (.36-inches) down at the bottom. This thinness helps to hide the phone's overall size, which is considerable. Its gorgeous 4.5-inch Super AMOLED Plus display hasn't been saddled with much of a bezel, but a screen that large is only going to appear on a hunky phone, and that this is. Measuring 132mm tall and 71mm across (5.2 x 2.8-inches) it's a big, wide slice of Android, but at least at 131g (.29 pounds) it won't weigh your pants or purse down too heavily.

The phone is your typical, simple rectangle; bulge at the bottom the only bit of shapeliness not left behind on the stair-stepper. Otherwise the back is completely flat, livened up by some texturing that makes it a pleasure to hold. Yeah, it's just plastic, but it almost feels classy. Almost.

Stick a fingernail under it and that class peels away, containing a beefy 1,750mAh battery and a slot for a SIM card. Beneath the battery is a microSD card, a measly 2GB that certainly puts off any pretenses of this being a properly high-end device. But, that's not all the storage this has to offer. Internally the phone has a 2GB hunk for apps, a separate 13GB slice for... whatever, and then the microSD card as well, which gives you a grand total of right about 16GB in three partitions.


Mount the phone to your computer and you'll see two shares, the larger internal bit of flash and your microSD card, meaning if you have a lot of tunes you'll likely have to split them manually. That's not the end of the world, and Google's Music app certainly doesn't care which share the files come from, but it's certainly not as clear as simply having a giant hunk of storage. Of course, there's nothing stopping you from throwing a 32GB card under the battery and using the internal flash memory just for your collection of Mystery Science Theater 3000 Gamera movies. Or, you know, whatever.

The speakerphone speaker is situated on the back, which is loud and clear, matching the overall call quality that we found to be quite good. Also on the back is the eight megapixel sensor paired with an LED flash, the same unit we've been getting quite familiar with lately in both the Charge and the Galaxy S II. Here it records video at a maximum of 720p and, like on the Charge, will auto-focus while recording. You can output that video over HDMI to your HDTV, but you'll need to rely on a dongle and the phone has to be plugged in to the wall while doing it. That's a bit of a bummer.

Display


Another smartphone from Samsung, another gorgeous Super AMOLED Plus display. This one steps things up a couple tenths of an inch to 4.5, but maintains the 800 x 480 resolution of its predecessors. This means pixel density is down ever so slightly, but what stands out here is the amazing brightness and contrast of this display. It looks as good as the company's other offerings, with deep blacks, searing whites, and infinite viewing angles.

Again the colors are a bit off when the brightness is lowered, and unfortunately Samsung didn't include the color tweaking tool that's found on the Galaxy S II. But, as with the Charge, we found if we kept the brightness up the colors were accurate, the whites bright, and the blacks still inky. That contrast is certainly the beauty of gooey organic LED displays, though there is another important advantage: power consumption.

Performance and battery life


We were very impressed by the battery life on the Droid Charge and we have to say we've been even more enamored here. The Infuse has a slightly larger, 1,750mAh battery pack nestled inside and it easily powered us through a day of demanding use. When managed more casually (as a typical user might) it got us through most of a second.

Of course, every phone will struggle to stay alive when being used as a mobile hotspot, and the Infuse is no exception. It can spew connectivity to up to five devices over WiFi, but you'd best have it plugged in to something if you want to do it for more than a few hours at a time.

The Infuse 4G is of course AT&T's first 21Mbps HSPA+ smartphone, its fastest yet, and when all the stars aligned perfectly we did see some impressive speeds. With full bars in San Francisco we managed an impressive 8.5Mbps down, but that was definitely a rarity. Most tests were in the 2 - 3Mbps range, with uploads at or below 1Mbps. In New York City we saw similar uploads but never broke the 3Mbps barrier going the other way.

Note, though, that these speeds were all over the place, seemingly fluctuating with some unidentified meteorological index and never offering the kind of consistently quick speeds we've seen on LTE. And, while the device did generally clock faster speeds than the Atrix when both were showing maximum signal, in general the Infuse seemed to be struggling a bit for bars comparatively, on average sitting about a notch lower. GPS locks were reasonably solid, taking a few minutes to figure out what state it was in but, after that, lining up the satellites quickly.

In terms of speed on the device, again we're talking a single-core phone, but at 1.2GHz it's a bit faster than the Droid Charge. We didn't really notice that in average browsing behavior, but the benchmarks don't lie. Quadrant scored 1,103, Linpack ran in 5.03 seconds and scored 16.657Mflops, while the Sunspider benchmark completed in 5,054ms. That's all on the order of 10 - 20 percent faster than the Charge, which goes to show that sometimes CPU cycles do count.

Camera


We're pretty sure the eight megapixel sensor slapped on the back here is the same one we've already seen in the Charge and the Galaxy S II so we won't blather on too much here, except to say that it's still very, very good. Pictures look sharp, colors look bright, and the 720p footage here is quite good -- if occasionally a bit soft.


The camera will auto-focus while you're filming without you having to tap on the screen, and the ever so subtle mechanical noise we heard on the Charge isn't noticeable here. Check it out for yourself in the video below, but only click play if you like dogs.


Wrap-up


The Infuse 4G is another solid offering from Samsung that we think those of you with wide pockets and big hands are going to fall in love with. It doesn't quite reach the blistering processor speeds of the Atrix, doesn't have a fancy composite back, and is completely bereft of laptop pretenses. It does, however, have a stunning screen that's big and the kind of battery life that could finally put your charge anxiety to rest. Maybe, just maybe, you could leave that second battery at home.

Droid Charge review

0 comments
We're still shaking our heads and sighing longingly at the performance of Samsung's Galaxy S II, a phone that wowed us in Europe but likely won't be coming to American shores for some time -- and who knows what it'll look like when it does. But don't get too down, dear reader, because here comes another slice of Samsung and this slab has that same 4.3-inch Super AMOLED Plus display tucked in there. It's a little less slim, a little less classy, and a little less quick than Sammy's latest world-conquering wunderphone, but the LTE-equipped Charge is a proper contender in its own right. Read on to see why.

Hardware


The Droid Charge is definitely a bit of a handful, as you'd expect with its 4.3-inch, 800 x 480 display. Still, we wouldn't call it a big phone by today's standards. It's .46-inches (12mm) at its thinnest, though it swells slightly in a little flare at the bottom (out to about 14mm). That's in the same ballpark of the recently-released Thunderbolt, which we're thinking many people will cross-shop this with. The Thunderbolt comes in at about .52-inches (13mm) thick, but the taper and profile on the Charge makes it seem thinner.

It's considerably lighter, too, 5.04oz (143g) versus 6.23oz (177g), though that relative lightness comes at a cost: a somewhat plasticy build. It certainly doesn't feel as bad as that Samsung flip-phone you had back in 2002, the one you rocked until your dog got ahold of it, but compared to the metal and unibody offerings seen elsewhere the Charge lacks any feeling of prestige in the hand.


It doesn't feel bad; there's a comfortable taper about it, a little bulge at the bottom that shifts the center of balance of the phone downward toward the center of your palm when holding it. It's quite comfortable to hold, helped by the smooth, glossy back that, sadly, seems a bit prone to scratches. There's a small grille on the back. Throw the phone in speakerphone mode and the voices of whoever you're speaking with come through loud and clear -- stress on the loud bit. Overall call quality and audio quality was good.

When in the hand, screen forward, power button on the right side and the volume rocker on the left fall to fingers quite readily. But, and here's something of a shocker, those aren't the only physical inputs here. On the phone's chin, which is designed with a hint of a pointy goatee, you'll find four honest-to-gosh buttons. Touch them and they actually depress! Some might call this a dated throwback to the olden days of cellular telephony, others will quite appreciate their presence. We like them, though we do wish they lit up a bit brighter.

Display


The buttons may be a bit dim, but there are no issues with brightness on that display, which again is 4.3-inches of Super AMOLED Plus goodness. Resolution is not jaw-dropping at 800 x 480, though the contrast is. Blacks are, naturally, perfectly black and the brights are borderline blinding in a darkened room, while viewing angles are unlimited. Even outdoors in the screen is quite readable. We had no problem composing shots when the sun finally broke through the clouds and lit up our weekend.

However, color reproduction can leave a bit to be desired. On the default, automatic-brightness settings, white sections of the display instead fall toward green. Remove that toggle, dial up the brightness and you get far more pure shades -- just make sure you squint a little before popping on the display in a dimly-lit area. The color-tweaking feature found on the Galaxy S II? Sadly not here, though the display is still mighty impressive even without.

Performance and battery life


The Charge is sadly not a member of the dual-core militia, but despite its 1GHz Hummingbird internals we found it to be quite responsive. You know, snappy. It won't blow your mind with ridiculous benchmark scores but, more importantly, it never left us waiting. In fact benchmark scores were something of a mixed bag, leaving us unconvinced that they're correctly reflecting the performance of the phone. Quadrant delivered scores around 1,000 and Linpack 13.8 MFLOPS -- on the poor side. Neocore, meanwhile, managed 56.8fps and Nenamark 45fps, while the Sunspider Javascript benchmark completed in a respectable 6,194ms. Again, most importantly the phone feels quick to use -- it's no Atrix, but it's certainly on par with the Thunderbolt.

When it comes to battery life, there's no competition. The Charge blitzed through a full day of what we'd consider typical use, coming off the charger at about 9am and not getting slotted back in again until 9pm the next night. Yes, you read that right, two working days of what we'd consider average use with GPS and WiFi on, taking pictures and videos, all powered by a single 1,600mAh battery. Granted, we weren't running our performance benchmarks at the time, but we were hammering the LTE antenna to get some speed results.


And what results they were! On LTE we managed a maximum download of 15.1Mbps down and 3.9Mbps up, enough to shame your average cable modem. And those with lots of friends (or lots of tablets) can share that connection with up to 10 devices.

Oh, and in case you're still worried about the GPS performance of your Sammy handset, fear not. The Charge didn't exactly impress us with its geolocation abilities, occasionally struggling to find a lock when in an occluded area, say on a porch or inside near a window. However, once in the clear it found enough orbiting birds in the sky quickly and accurately.

Software


The Charge comes with Android 2.2 Froyo installed and, yes, that's a bit of a disappointment in these days of Gingerbread, but the light customizations applied here by Samsung help to keep it looking somewhat fresh. The phone's lock screen has you dragging a puzzle piece to get access to the main OS, though missed calls and other events will pop up here and, if you put them in their place, you'll be taken right to whatever event caused them to appear in the first place.

A healthy seven home screens are on offer, and pinching on any of them zooms you out to see them all from high, high above. By default the middle one is your go-to screen, but you can choose any of them to take that place. Samsung adds a few custom widgets to the mix, but nothing too mind-blowing, like a dual-clock that will tell you what time it is at home and afar, plus a task manager widget that's handy if you think you're better at memory cleaning than Android.

The cool accelerometer-augmented gestures for zooming and moving on the Galaxy S II are sadly not here, however there are a number of inclusions here that are rather less wanted -- a huge amount of icons for bloatware and game demos that cannot be removed. They're not exactly filling the phone to capacity, but having three full pages of apps on your phone the first time you boot it up seems a bit excessive.

Camera


Out through a little chrome highlight on the back of the phone peers what we believe is the same eight megapixel sensor that earlier impressed us on the Galaxy S II. It impresses us here, too, capturing bright, clear images even when lighting conditions are less than optimal. Tap-to-focus quite naturally works, but we were pleasantly surprised to find that the camera used auto-focus when capturing video.


The payback is a little bit of focus noise injected into your footage, a sort of tapping you can hear in the sample above, but we didn't find it to be too obtrusive. However, the auto-focus is a bit slow, so we still preferred manually focusing by tapping. Video quality is again quite good, not quite the 1080p stuff that the Galaxy S II can deliver, but there's only so much you can do with a single core processor.


Wrap-up


The Droid Charge is a total sleeper. We'll be perfectly honest that we weren't expecting to be wowed but, well, we're certainly impressed. In terms of performance it's more or less on par with the recently-released Thunderbolt, but battery life is far superior and, while the Super AMOLED Plus display has its quirks, we think they just add character. The imaging sensor 'round the back is top-notch and, overall, this is a very good phone. The only real disappointment? A plastic design that probably will be looking a bit rough after a few months in your pocket.

And then there's the cost: $300 on-contract puts the 32GB Charge in an unfortunate tie for the position of Verizon's most expensive smartphone. That tie is, of course, with Apple's 32GB iPhone 4. That's $50 more than the Thunderbolt, which also comes with the same number of gee bees. Worth the extra? Given the battery life and display improvements here, we'd be inclined to say yes.
