HTC Droid DNA

i was using iphone 3 before i got Droid DNA. i prefer this better than iphone. the battery life is the main feature. this has long life compared to the other phones i used. the camera is 8 mega pixcel and i was able to take very clear photos. i dont need to use my camera anymore because this has got a very good video recorder too.

HTC_Droid_DNA_35536642_06_540x386

the display is very crisp and the text and photo are very clear. i was watching the HD YouTube videos on this 5 inch screen. thats convincing. as far as i know it’s not the most advanced version of the OS that Google has officially announced, but however  this is as fresh as you’ll likely find outside of a true Nexus device.

iphone 5 is here to dominate

This Latest smart phone from apple has been a big success, as many users have liked its slim look and crisp clear screen. The screen is made of gorilla glass which is scratch resistant, which makes the user feel that the screen is pretty robust. Compared to the other previous smartphones that were developed by apple, this has got a longer display and the weight has been reduced, which makes the user feel that the phone is as heavy as a feather.

The IOS 6.0 is effective and the users can use the Siri function to do tasks by just talking the way you talk to a human being. The advanced AI helps the user to do tasks with ease as it understands what the user really means. One can call, text, even set reminder my talking to Siri.

 

IPhone 5 has a special sensor just like the other smart phones, which turns off the display light, when it’s close to your ear to avoid accidental touches, however if you take the phone away from your ear, the display comes back so that you can click and navigate to other options. This is simply cool once you experience it for real.

 

The camera in this smart phone is simply superb, as it has some special features to take close up photos which can be taken in poor lighting conditions too. The 8 megapixel camera is more than you would bargain for, because the camera does not contain any complex features to take a photo. Users have to just run the camera app and start taking photos with ease. Unlike its predecessor’s the photo gets stored within seconds and you can get ready to take the next shot. With the camera function this smart phone also has a video recorder which takes video’s in 30 frames per second that can be compared with standalone digital camera video recordings.

 

One would feel the disadvantage of this smartphone could be its screens height. The width is the same size as its predecessor, but height has been increased which gives it a weird look. Battery life is very short and its quite annoying to charge the phone each and every day for approximately 2 hours, however all the other non-apple smart phones share the same problem, so the users can’t really consider this as a big let off. According to my knowledge this phone stays alive for 24 hours or so, but when on wifi, it’s got much shorter battery life.

Windows releasing the best smart phone ever…

Nokia Lumia 920 review

35436251-10_610x435

 

This smart phone is quite heavy and thick and has a look and impressions that makes people think of it as a tablet pc because of its size.  I find it very hard to put it in my pocket most of the times, however this phone has got a smooth look which makes us forget the thickness. As a user i always felt happy to carry the phone in my hand and utilize its full features when necessary.

 

The newly introduced wireless charging function is awesome, but i feel that the direct cable charging charges quickly. Even though they call it wireless charging, it does not mean that the phone can be charged  while you are on phone or withoutout touching the fatboy pouch. Fatboy pouch gives a different feel when charging the phone wirelessley, it saves time by not encouraging us to plug in the cable. All you have to do is, just place the phone on top of the pouch and wait til it gets charged. This is something that i was waiting to try for years.

nokia-lumia-920-vs-iphone-4s-cameras-0

Lumia 920 has a 32gb memory which is not enough for most of the users as they all download a lot app apps which requires more space. This is a drawback of this particular smart phone which has to be rectified in the near future. However when you compare the memory with other smart phones which a are available in the market, this does not seem a big problem. This device has So far the biggest screen size i have ever experienced.  The screen size is more than 4 inches. so i am able to view more contents than any other phone i used in the past. Camera feature is not at all convincing, because no matter how big or small your photo resolution is, the phone always stores it in 400 Kilo Bytes.  I really dont understand how this is possible as iphone and other devices store high resolution photos in Mega Bytes.

 

According to my knowledge, this is the only phone where i can touch the screen and open programs with gloves and navigate with ease. As far as i know, no other phone had this feature, and hopefully will not have it in future too. When it comes to the multimedia side, i prefer listening to music via headset rather than throught the speakers. I was able to hear boost in songs  when listening to music after activating dolby-boosted playback which had amazing equalizer settings too.

HTC One …

HTC One has Rectangular, flat, and extremely thin, the HTC One is practically all screen. Its 4.7-inch LCD display uses the SoLux technology for improved picture quality and generates 468 pixels per inch. This helps the screen to boast the most impressive viewing experience of any phone it has ever created. Since the display is slightly smaller at the same resolution, the One’s screen has a denser pixel count than the Droid DNA

012HTC_One_35616143__1_610x417

the display has plenty of impact with vibrant colors, wide viewing angles, and plenty of brightness. Details also look extremely crisp. Just how this device’s screen measures up against the best mobile displays from Samsung and Apple, however, remains to be seen.

 

HTC also makes a big deal about the One’s all-aluminum chassis, describing it as using a zero-gap unibody design. Indeed, available in hues of black and silver, the handset feels sturdy, has reassuring heft, and its smooth metallic skin exudes high-end craftsmanship. HTC also took pains to point out that while the thin white trim encircling the silver model I manhandled appears to be plastic, it is in fact meta

 

dual speakers act in unison to deliver a more lively audio experience whether while watching movies or listening to music. Paired with an onboard amplifier and Beats technology, HTC has given the system the rather unfortunate name BoomSound. It reminds me of the kind of cheesy trademark Philips used to plaster all over its old boom boxes.

 

A flagship smartphone wouldn’t be worth its weight in salt if it wasn’t backed up by a bevy of screaming components. You’ll be glad to know that the HTC One doesn’t disappoint. Beating inside the heart of this regal machine is a 1.7GHz quad-core Snapdragon 600 processor, fresh off of Qualcomm’s factory floor. It’s the first device I know of to officially feature the new silicon. Because of that I’m sure a lot of smartphone addicts out there will be itching to get their hands all over this gadget.

 

In the limited time I’ve spent with the HTC One, I can definitely say it’s fast, thin, and flaunts a very sexy design. Of course these words describe a lot of new smartphones. If the phone’s screen and camera live up to the hype, however, then HTC may have a big winner on its hands. I have to say I am concerned about the BlinkFeed feature, which may be exciting for Android newbies but doesn’t seem extremely useful for smartphone old hands.

 

 

Transparent smartphone prototype is clearly cool

Many smartphones look the same from afar. I bet most of you own one that’s thin, rectangular, and features a big screen. Boooring!

A fully transparent conceptual smartphone, developed by Taiwanese company Polytron Technologies, gives me hope for a future full of fancy smartphones far different from the common designs seen today.

Your future smartphone

 

Mobile Geeks had a chance to personally preview Polytron’s impressive see-through smart-glass gizmo, but it’s worth noting that the current version can’t make calls (yet) and isn’t fully transparent due to limitations with modern technology.

As evidenced in the below preview video, several internal items such as the SIM card, SD card, and microphone can be clearly seen. As Polytron moves toward a more complete device, the company plans to shift many of those visible components to an opaquely shaded area at the bottom while hiding other items, such as the camera, with darker glass.

That’s not the complete story, though. Due to Polytron’s Switchable Glass technology (based on Polyvision), the entire phone may appear opaque when not in use, and clear when powered on.

Polytron perhaps explains the now-you-see-it/now-you-don’t display technology best: “When the power is off, the liquid crystal molecules are randomly oriented [way] that scatters incident light and the screen becomes opaque. When electricity is applied, the liquid crystal molecules line up, the incident light passes through, and the screen looks clear.”

Polytron plans to assemble working prototypes of the transparent smartphone and even move toward limited production by the end of the year, according to Mobile Geeks.

Elegant smartphone with a huge flaw

With its recent history of mediocre handsets, LG needs something other than the Optimus G to be its Hail Mary that can carry it to the top. Unfortunately, the Nexus 4 isn’t quite it.

Don’t get me wrong, the device itself performs excellently, and some of the specs are certainly impressive: the quad-core CPU is swift, the Jelly Bean Android OS runs as smooth as butter, and all the subtle new features work well without being too unintuitive or burdensome.

But Google’s flagship phone is missing one huge feature that caught us all off guard. The Nexus, which is supposed to represent Android in its most modern, so-high-tech-that-it’s-on-the-bleeding-edge form, isn’t 4G LTE-enabled.

Instead, it operates on “4G-ish” technology (GSM/HSPA+), and comes unlocked from Google (starting on November 13, the 8GB and 16GB versions will be $299 and $349, respectively) or on T-Mobile (after signing a carrier agreement, the 16GB model will be $199 and will begin selling the day after). If your carrier is T-Mobile you won’t care much, since the network runs on HSPA+ anyway. But for those who had been planning on buying the unlocked model and using it on, say, AT&T’s 4G LTE network, the news is truly a downer.

Truth is, while HSPA+ can be as fast as LTE, for the average consumer LTE is expected on high-end phones. Jelly Bean and the pure Android experience will be important for OS enthusiasts, but this phone should have had both. And yes, I know the Galaxy Nexus didn’t have LTE, either, when the technology was available. I was disappointed then, too, even though the network wasn’t as robust. But now that LTE is so widespread, the Nexus 4 shouldn’t get a pass. A handset this high-caliber should have LTE capability, especially these days, when so much time has passed since LTE’s launch and even midrange devices come with it.

Design
If I were to sum up my impression of the LG Nexus 4’s look in one sentence, it’d be this: even though the smartphone has LG’s logo slapped on its back, it has Google written all over it.

Don’t get me wrong, you won’t see Andy anywhere on the handset, nor will you see any blue, red, yellow, and green lettering. But the device’s design noticeably lacks LG’s past aesthetic.

jelly_bean

Yup, this is definitely running Android Jelly Bean.

 

Gone are the bezel hot keys that light up when in use, and there’s no physical home button. Instead, the shortcut keys for back, home, and recent apps appear on the screen itself, just like they do on the previous Nexus. Also gone is the straight-edged touch screen. In its place is a display that softly curves into the bezel, which adds that luxurious extra oomph, and it’s something I’m a huge fan of.

Lastly, the top and bottom edges of the Nexus 4 curve outward, giving the device gently rounded corners. This is a welcome departure from LG’s recent string of mid- to high-end smartphones that were sharply rectangular and austere.

Not everything looks great, however. The phone’s edges are coated with a matte plastic, rubbery material, and they turn inward at a sharp, jagged angle. And if you want to access the inside, you’ll need to use a tiny screwdriver, which will be inconvenient for some.

Overall, the design is nothing we all haven’t seen before. Yes, the Nexus 4 does look and feel like a premium handset, but it’s uninspiring. It measures about the same as most big, 4.7-inch phones (5.27 inches by 2.7 inches by 0.36 inch), so it’ll be a tight squeeze in small jean pockets. It’s a wide fit in the hand but is comfortable to hold, and while it’s only 0.1 ounce heavier than the Samsung Galaxy S3, it feels noticeably denser and sturdier.

On the left is a volume rocker and up top is a 3.5mm headphone jack. The sleep/power button is on the right spine, and the Micro-USB port is on the bottom edge. Above the display in the top right corner is a 1.3-megapixel camera and below the screen is an LED notification light. The back of the phone houses an 8-megapixel camera and an LED flash.

Now, about that distinctive sparkling back plate: personally, I don’t mind it. You can only really see it in the light, and it reminds me of either Tetris or “The Matrix” (two things I’m fond of). There are others, however, who don’t like it and say it makes the phone look like a “Sailor Moon” sticker card.

Display
Though the LG Optimus G and the Nexus 4 have the same 4.7-inch True HD IPS+ touch screen with the same 1,280×768-pixel resolution, and both are made out of Corning Gorilla Glass 2, the usable screen space on the Nexus 4 is actually smaller because of the onscreen hot keys. Sure, the icons move out of the way when you’re watching videos or playing games, but that third of an inch of lost screen space (especially given that the two devices are nearly the same size) is noticeable when browsing the home screen or surfing the Web.

Having said that, however, the screen is still impressive — it’s bright, text renders crisply, colors are true to life and vivid, and it’s sensitive to touch input. Something about swiping my fingers across it and letting them fall off the edges felt incredibly slick. Even the slightest touch will register, without being inaccurate, and typing with Gesture Touch (more on that later) was exceptionally smooth.

Understandably, on the Optimus G and and the Nexus 4, photos and videos looked practically identical. There were a few times when colors on the Nexus 4 had warmer tones and less contrast, but these instances happened so rarely that it’s difficult to make a call between the two.

On the other hand, differences compared with the Samsung Galaxy S3 were much more prominent. Colors on the Galaxy S3 were more saturated, greens looked deeply green, and whites had a subtle blue hue to them. Dark colors, like black and brown, were harder to distinguish from one another. Though there were times when the richer palette made photos and videos look better on the S3, the Nexus 4 displayed colors that were truer to life without being muted.

Interface and basic features
Unlike the overhaul that was the change from Android Gingerbread to Honeycomb to Ice Cream Sandwich, the change from ICS to Jelly Bean is subtler. In general, the aesthetics of the UI remain about the same: Roboto is still the dominant font, menus and icons keep the same minimalistic look, and the elegant simplicity of ICS is retained overall. In fact, only hard-core Android devotees would be able to tell it wasn’t ICS even after spending a few minutes with it.

interface

The interface for incoming calls has been slightly tweaked.

 

However, the minor changes that are present are welcome, such as resizable widgets; a more expansive notifications bar that lets you see more information about things like e-mails, texts, and screenshots; offline voice dictation; more wallpapers; updates to Google Play; and updates to Android Beam, which now allows you to transfer more-complex files like photos and movies over NFC.

Google Now gets more accurate with its suggestions and transportation estimations the more you use your phone.

 

Another feature is Google Now, which is closely tied into Google Search and Voice Search. Because Google Now isn’t technically a voice recognition service, it’s not like iOS’ Siri. But it does have voice assistant-style abilities. For instance, it can suggest local restaurants and estimate your commute time.

For more information, read our review of Jelly Bean.

Basic features include a calculator, a calendar, a clock with alarm functions (with an extremely beautiful interface, I must say), an e-mail client, a movie-editing app, and a news and weather app. And all the Google apps you come to expect are preloaded: Chrome, Currents, Earth, Plus, Search, Local, Maps with Navigation, Messenger, Talk, Voice Search, YouTube, and the Google Play Books, Magazines, Movies and TV, Music, and Store portals.

Android 4.2: What’s new for Jelly Bean?
Right when I turned on the handset, it prompted me for an update to version 4.2. This brought a few more features, most of which involve the camera (I’ll expand on that later). Another feature is Gesture Typing, a typing input method that’s similar to Swype. Swype is a third-party app that allows users to swipe through the letters to form the words they’re typing out, instead of hitting individual keys. It’s a faster, more convenient way of typing that’s rightly loved by Android users. Gesture Typing is a native feature that works in the same way.

typing_method

Gesture Typing, a native typing input method, works similarly to Swype.

 

There’s also Daydreams, a sort of screensaver sleep mode for your phone whenever it’s docked or charging. Options include a graphic of floating jelly beans you can interact with through touch, a mural of headlines gathered from your Google Current subscriptions, or a shifting color gradient. In addition, photos from your albums can be displayed, either individually or piled on one another like a stack of physical pictures.

Camera and video
Shooting options and editing: The LG Nexus 4’s 8-megapixel camera sports a new user interface that is now even more minimalist than the previous Nexus iteration’s. Photo options can be reached through a radial dial that you can access by either tapping on the circle on the right-hand corner, or tapping anywhere on the viewfinder itself.

These options include flash, geotagging, and 3.9x digital zooming, five white-balance modes, five scene modes, seven photo sizes, an exposure meter ranging from -2 to +2, and HDR shooting. You also get touch and autofocus. The front-facing camera retains most of these features save for the flash (obviously), and there are only three photo sizes to choose from.

In addition, you can take panoramic pictures and Photo Spheres, a new feature in Android 4.2. Photo Sphere stitches together pictures taken from every angle at a single point, to create expansive 3D-esque photos. Though you need to spend some time to take all the photos, the spheres never fail to impress people, and they’re great when you want to record and share an all-encompassing scene, like when hiking or buying a new house. Though I had a little trouble figuring out how to use it in the beginning, the feature works reliably and swiftly. There were a few times, however, when the feature didn’t allow me to capture the very bottom and very top of a scene, which resulted in huge black holes of empty space in my photos.

photo_sphere

Photo Sphere patches together several pictures and renders them into (nearly) a 360-degree image.

Aside from the exposure meter, rear-facing video features consist of the same options. However, there is an additional time-lapse mode and you can select from three video qualities, the highest being HD 1080p. If you want to record with the front-facing camera, the highest quality you can shoot in is HD 720p.

The photo gallery also went through a makeover. You can browse through photos in a filmstrip view by slightly pinching in on an individual picture. To delete a photo, simply flick it off the screen. To edit an individual image, select the icon of three intertwining circles at the bottom of the display.

Editing options include 10 lens filters, not unlike the ones Instagram offers. You can also overlay seven different types of borders, crop a photo, or adjust sharpness, exposure, contrast, hues and saturation levels, and much more.

android_jelly_bean

Android Jelly Bean includes new photo-editing options that are quite Instagram-esque.

 

Photo quality: In photo quality the Nexus 4 was very similar to AT&T’s Optimus G. In sunny outdoor shots (and even on gloomy, overcast days), images were in focus, with crisp, well-defined edges. Photos didn’t necessarily “pop” with saturated hues, but colors were true to life. I found that whites, even on auto white balance, were especially accurate. In low or indoor lighting, pictures understandably fared worse. Dark hues were harder to distinguish from one another, and when zooming in at full resolution, there was more digital noise and pixelation.

video_shot

             In our standard studio shot, objects are in focus and colors are true to life.

The camera performed well; there was no lag in feedback when I moved it. However, for a handset that performs so speedily in every other aspect — running games, Web browsing, and the like — the shutter speed is comparably slower than the iPhone 5’s and the Galaxy S3’s. Snapping one picture is fine, but when I rapidly and continuously pressed the shutter button, the time it needed to refocus stalled its shutter time.

Video recording was also respectable. Audio picked up well, colors were accurate, and moving objects, like passing cars, remained in constant focus with clean outlines and little pixelation. The refresh rate during playback was high and images rendered smoothly.

Performance
Call quality: We tested the device on T-Mobile’s network. Signal quality both indoors and outdoors was great. I didn’t hear any audio clipping in and out, no calls were dropped, and I didn’t hear any extraneous buzzing.

Call quality, however, was a different matter. Every test call I made was to a landline phone, and for the in-ear speaker, audio volume was too low. There were times, especially outdoors, when I couldn’t make out what my friends were saying, even after cranking it up to maximum volume. Switching to speakerphone helped a little, but if I turned the volume too high, voices sounded extremely harsh. This makes sense since sound can only escape through a thin slit in the back of the phone, so my friends sounded really tinny while speaking. The speaker also rendered music flatly. Its small opening strips away much of the depth and body, especially from songs that are instrumentally rich.

Furthermore, even in regular (not speakerphone) calls, voices sounded slightly staticky, and every word I heard was layered with a subtle fuzz. Likewise, a friend reported to me that I sounded too sharp, as if the bass was turned down on my voice while the treble was turned up.

Whether the lack of LTE matters: If you’re a T-Mobile customer, the answer is no. T-Mobile’s “4G” was always based on HSPA+ technology and it never offered LTE, anyway (though the carrier does plan on launching it next year). So for those of you who belong to the carrier now, this handset is one of the best phones T-Mobile is offering.

On average, it loaded our CNET mobile site in 6 seconds and our full desktop site in 8 seconds. The New York Times mobile and desktop sites took 7 and 14 seconds to load, respectively. ESPN’s mobile site downloaded in 7 seconds, and the phone took 15 seconds to load the full site. It took a mere 50 seconds on average to download the 22MB game Temple Run. And the Ookla speed-test app showed me an average of 8.15Mbps down and 0.5Mbps up.

However, if you buy the phone unlocked, you won’t be able to use any carrier’s 4G LTE network. As I stated before, LTE has become a staple in mid- to high-end phones and the technology is no longer in its infancy. And while some surmise that operating on GSM/HSPA will make the Nexus 4 a more global device, it’s still a letdown for the U.S. market.

Processor and battery: Though the Nexus 4’s data speeds might not be blazingly fast, the 1.5GHz Qualcomm Snapdragon S4 Pro quad-core CPU makes its internal speed swift and smooth. Graphics-intense games like Riptide GP and Asphalt 7 played extremely well, launching and running with no stalls or hiccups. The games both displayed high frame rates with high-resolution graphics.

cpu_camera

            Because of the phone’s ultrafast CPU, gameplay was crisp, smooth, and fast.

In addition, average start time for the handset was about 23 seconds, and it took about 1.82 seconds to launch the camera. Browsing on Chrome was a lot smoother on this device than on the Optimus G for some reason. For instance, scrolling down Web pages was executed much more swiftly.

During our battery drain tests for video playback, the device lasted 8.1 hours. Anecdotally the handset had short battery life. Though it’s powered by a 2,100mAh battery, the screen takes much of its reserves. I needed a few good charges to get me through the day, and playing a 22-minute show drained about 10 percent of the battery’s power. According to FCC radiation standards, phone has a a digital SAR rating of 0.56W/kg.

Conclusion
In general, the device is excellent and reliable — its internal speeds are zippy and smooth, the camera is packed with new features, and Android 4.2 is indeed sleek. The Nexus 4 is one of the best LG phones out there alongside the Optimus G, and for such a recognizable phone, it’s extremely affordable. In addition, if you’re already a T-Mobile user, the Nexus 4 is the carrier’s best offering next to the Galaxy S3.

But aside from natively sporting Android Jelly Bean, the Nexus 4 doesn’t offer up anything significantly new. If you ask yourself, what does this phone do to expand and progress the Nexus brand? The answer is, nothing much.

Though it’s fast, the Optimus G also has a quad-core CPU and the AT&T model is 4G LTE-capable to boot. Compared with the Samsung Galaxy S3’s design, the Nexus 4 looks all too common. And if you’re concerned about what Google said about LTE and battery life, look no further than the Motorola Droid Razr Maxx HD. Plainly put, while the Nexus 4’s HSPA+ speeds are respectable, its lack of LTE capabilities will definitely leave users feeling behind or slighted.
