NOKIA LUMIA 920The jewel in the crown of the Windows Phone. The Nokia phone has become her own merits in the most desired by users of the platform, which makes the Lumia 920 so unique from the competition?For starters, its spectacular display PureMotion IPS technology, which ensures a much higher response rate than that of its rivals, plus a high brightness even under sunlight and an incredible touch sensitivity. Its density of pixels falls below the HTC 8X, but instead offers a slightly larger screen coming up to 4.5 inches. On the performance side, processor and RAM shared with rivals, and stays at an intermediate point on the capacity of the battery, below the Samsung ATIV S.But if there is another feature that is special about the Lumia 920 is its main camera. Beyond its 8.7 megapixel, the largest of the three phones compared, which has led to more comments PureView technology is used by Nokia that offers quality in the photographs as had never before seen on a mobile. His system allows high quality photos in low light conditions and image stabilizer, polemics aside, substance ensures improved video recording from the competition.The dimensions of Nokia smartphone loses out, being the thickest of the three little heavy and quite unlike most of its 6.53 oz. In return we have a more compact look great all the design "unibody" inaugurated with Nokia N9. Care adds details, such as wireless charging sold separately.HTC 8XThe headliner HTC is all a sample of expertise and stand out very well against its rivals, with several points in which the lead.The screen is not one of the sections which emerged victorious. The HTC 8X offers the smallest screen of the three devices with its 4.3 inches, but it does maintain a great resolution of 1280x720 which give it the highest density of pixels from the comparison. Its Super LCD technology maybe stay a little behind the rest but offers more than enough quality. In their guts have the same processor dual-core Snapdragon S4 of ATIV S and 1GB of RAM, although in this case with less battery of three in competition. Storage also remains somewhat behind, with 16GB internal and lack of microSD card slot.Paragraph photographic eye, because, without hogging all attention wing that has taken the Lumia 920 in this issue, the 8X offers an 8-megapixel camera more than satisfactory, equipped with technology similar to what HTC has offered in its latest Android devices . And to complete the multimedia section, nothing better than to take their work with Beats Audio for great sound provide the terminal. Not to mention LTE and NFC connectivity it shares with its other two rivals.Despite seeming to be left behind by its smaller battery, less internal storage and lack of microSD slot, the explanation is found faster when we take a look at its small size. The 8X is the smallest of the three high-end WP8, but still thicker than the ATIV S, leaving its weight in a mere 4.59 oz. To this we attach a very attractive design that has received very good reviews from those who have had their hands in appearance and comfort.SAMSUNG ATIV SProbably the most enigmatic of high-end phones with Windows Phone 8. Samsung is superior in several sections.The ATIV S boasts the largest screen size with 4.8 inches they leave behind its competitors. Also, this comes with HD Super AMOLED technology so successful that the company has made on other devices. Instead maintains the same resolution 1280x720, leaving a lower pixel density than its rivals, although still at very high levels. Again we have a dual-core processor at 1.5 GHz and the same 1 GB of RAM, although in this case is supported by a battery of 2300 mAh, significantly better than their opponents. As for storage, the Samsung is the most flexible, allowing internal choose a size 16 or 32 GB and appending its possible expansion with microSD cards.The camera is perhaps where worst comes stopped ATIV S compared to the other two competitors in the high range. While maintaining the type with its 8 megapixel, lack of promotion by Samsung of the same rule we can think of as technological added special in this case advertise their rivals. The rest of the features is on par with its rivals, including the maximum connectivity LTE and NFC.That if, as a work of engineering the Samsung smartphone stands out from the rest thanks to its spectacular screen size in the body content thinnest of the three, with just 0.34 in. thick. To that we can add their meager 4.76 oz, almost on par with the HTC 8X, and you have a real beast of a body very content. Surely its design is the least attractive of the three, but that can be a strength that will help convince users who prefer a more sober style on their phones.I hope to help you in your decision with this modest analysis.
