The LG Optimus 4X HD is the first phone to feature Nvidia's Tegra 3 chip offering significant mobile gaming performance at release. LG Optimus 4X HD was also the first phone announced with a quad core processor. The chip has four physical cores clocked at 1.5 GHz in addition to a lower-clocked fifth core. The fifth core is clocked up to 500 MHz and runs when the handset is idle or doing only simple tasks, less-demanding tasks such as active standby and music playback.LG Optimus 4X HD is equipped with a True HD IPS display with Ultra high resolution 313PPI, packaged in an 8.9 mm-thick, prism-edged design. The device comes in black and white The LG Optimus 4X HD also includes a 12-core graphics processing unit. There is an 8-megapixel backside-illuminated sensor camera on the rear with LED flash, HDR, continuous shot, support 1080p Full HD video recorder and 1.3MP camera on the front for video, conferencing or self-portrait. The phone also includes a Li-Ion 2150 mAh battery, stand-by up to 730 h (2G) / up to 686 h (3G), talk time up to 9 h 20 min (2G) / Up to 10 hours & 50 minutes (3G). MicroSD card slot up to 64 GB, internal memory 16 GB (12 GB user available), and 1 GB RAM. It has a highly capable face unlock feature which works with the front-facing camera.
By now you're probably wondering how that 4.7-inch True HD IPS PLUS panel stacks up to the competition. LG's Zerogap Touch technology puts the capacitive layer right inside the non-PenTile, 1,280 x 768-pixel screen for an ultra-thin design. It's definitely a top-notch display -- bright and crisp, with deep blacks and rich colors. Still, it falls short of HTC's gorgeous Super LCD 2 panel on the One X, which offers better viewing angles and remains the best screen on any phone we've ever used. Our Korean unit also suffers from a yellow discoloration at the bottom of the display -- it's mostly noticeable with a white background and we've alerted LG to the issue, which is likely the result of an early batch of defective panels. The Sprint and AT&T devices are flawless.
We've detailed UI 3.0 in other reviews before (Optimus L7, Optimus 4X HD and Intuition) but some of the existing features stand out. We're rather fond of the quick settings menu, a scrollable (and customizable) bar of icons at the top of the notification tray which provides shortcuts for various settings. Strangely, the hotspot quick settings icon is missing on AT&T's version (like on the LG Escape, it turns out). Perhaps it's an attempt by the carrier to discourage tethering? The app tray includes some welcome additions like folders and the ability to sort icons alphabetically or by installation date. "Icon Personalizer" lets you swap icons for any home screen app. "Quiet time" works like Apple's "Do Not Disturb" by defining times when notifications are muted. You'll also find a few Optimus G-specific tricks. "Wise Screen" is similar to Samsung's "Smart Stay" and prevents the phone from going to sleep when you're looking at the display. "Dual Screen Dual Play" lets you play back content on an external monitor connected via MHL or LG's Miracast dongle while you're performing other tasks on the device. "Live Zooming" enables pinch-to-zoom during video playback (up to 5x). Last but not least, "QSlide" overlays videos in a transparent window that floats over whatever app you're currently running -- it's really quite slick.
LG has an ongoing smartphone problem: despite a few valiant efforts (the G2x comes to mind) the company continues to live in the shadow of rival Samsung. Most of this malaise can be attributed to hit-and-miss hardware combined with lackluster software (we're looking at you, Spectrum). Last February, at Mobile World Congress, LG spiced things up with an attractive collection of devices including the Optimus L7, Optimus Vu and Optimus 4X HD -- the latter being one of the first quad-core handsets announced. Now, six months later, we live in a world where the global versions of HTC's One X and Samsung's Galaxy S III dominate the superphone market and share the quad-core crown. With me-too features like a Tegra 3 processor, 4.7-inch HD display, 8-megapixel camera and Ice Cream Sandwich on board, the Optimus 4X HD appears ready to play in the big leagues. Does it succeed or is it just a flash in the pan? Is it all style over substance or does it bring something unique and meaningful to the table? Hit the break for our full review.%Gallery-159951%
In front, the Optimus 4X HD is all Gorilla glass. A white bezel surrounds the 4.7-inch display, interrupted only by three backlit, capacitive buttons at the bottom and the proximity sensor, earpiece, LG brand and 1.2-megapixel front-facing shooter up top. That silver LG logo looks like an afterthought right below the earpiece's tastefully recessed white mesh grille. It's worth noting that those capacitive keys are invisible until backlit and difficult to see in bright sunlight so you'll have to memorize the order: back, home and menu (from left to right). Yes, like Samsung with the Galaxy S III, LG's clinging on to some vestigial menu button instead of rightfully providing a recent apps key. While a long press of the home button brings up the recent apps list, the 4X HD's key layout is the exact reverse of the Galaxy S III's. Why is it that, two Android versions beyond Gingerbread, manufacturers still can't agree on button placement? Here's a hint Samsung and LG: Ice Cream Sandwich and Jelly Bean already provide a standard key layout -- use it.
Sadly, the Optimus 4X HD's "True HD IPS" capacitive touchscreen falls short of the One X's phenomenal Super LCD 2 and the Galaxy S III's brilliant Super AMOLED displays. It's certainly a fine 4.7-inch, 1,280x720-pixel panel in its own right -- non-PenTile and bright, with deep blacks, natural colors and respectable viewing angles. The problem is glare, especially in direct sunlight and when looking at the screen from vertical angles greater than 30 degrees. We suspect that this is the result of the display not being bonded to the front glass -- a glaring omission (pun intended). This deficiency can somewhat be overcome by boosting the screen brightness, but at the expense of battery life, of course.
Battery life, however, is less stellar. In our standard rundown test, where we start with a full charge and play a video in a loop with the display brightness and volume set to half, a 75 percent or better 3G signal, WiFi and GPS enabled but disconnected, and Bluetooth disabled, the Optimus 4X HD's 2,150mAh battery lasted six hours and 21 minutes. That's on the lower end of the spectrum when compared to the current crop of high-end Android phones. Also, while this result is similar to what we observed with the Tegra 3-equipped One X, HTC's flagship only packs a 1,800mAh cell. We managed to get about 14 hours of moderate use from the 4X HD -- that's checking email and social networks, occasional calling and texting, taking a few pictures and light web surfing. This means most folks will be able to use LG's quad-core Optimus for an entire day on a full charge but power users will likely want to bring a charger.
The company was often ahead of its time with its designs as well. The LG BL40 New Chocolate (from 2009) was the first phone to have a screen with an ultra-wide 21:9 aspect ratio. It was ridiculed at the time for looking line a remote control, but ultra-wide displays are the norm now.
A first in the industry, the KOP555 kiosk enclosure incorporates 4K displays, in conjunction with a self-service configuration, turnkey installation and hardware integration from partners including NEC Display Solutions, Samsung, Sharp, Panasonic, Philips MMD, LG and AOpen. The KOP555 is the only outdoor kiosk to allow integrators to use any display for their outdoor digital signage kiosk at an economical cost, while protecting the display and other electrical components.
That said, I did notice a bit of weirdness when I viewed the color white from off-center. Whenever I had a 100% white screen displayed on the C2, the white would subtly shift into a very pale green as I moved about two feet away from a direct angle. By the time I got to an extreme off-angle position (about five feet away from the center), the subtle green had gone pink.
As part of its effort to improve its hold on the smartphone market, the consumer electronics giant LG announced a series of smartphones in last few months. The LG Optimus 4X HD is definitely a frontrunner in the new smartphone area with its quad core processor and super clear display. Check out reviews of other LG Optimus series phones.The LG Optimus 4X HD smartphone was originally announced at the Mobile World Congress in February 2012, but it took awhile to reach the smartphone market in the global market. I got a chance to review this phone in a launch event in Mumbai and then got the phone for a detailed video review couple of days back. If you'd like to learn more about the 4X HD Android phone, read this hands-on review.The LG 4X HD comes in a small, stylish box. The box contains the phone, a 3.5mm earphones, user manual, power connector and a micro usb cable. The package is very attractive, even though that is not the real criteria to judge a phone.Nvidia Tegra 3 Quad Core ProcessorThe Nvidia Tegra 3 Quad Core Processor in the LG Optimus phone is powerful enough to run most of the mobile apps and can play any mobile games currently available. With 1.5GHz clock speed and supported by 1Gb RAM, this phone is definitely a power horse. It boots up instantly and you can start the job without having to wait for the phone to get ready. Supported with 1GB built-in RAM, this phone is your best buddy to perform any mobile computing needs.High definition display of Optimus 4X HDWhen you turn on the phone, the first thing you notice is the crystal clear, high definition display. The 4.7" True HD display is considerably big and larger than most other smartphones. Remember the iPhone 4 display size is only 3.5 inches. When you place this phone near an iPhone, it looks much wider and taller. The very responsive screen improves the experience significantly.Optimus 4X HD offers 1280x720 display (compared to 960 x 640 resolution of iPhone 4S), which is not very common in smartphones. This LG phone offers very good brightness and colors. The lcd screen on 4x HD make the images more richer in color and the brightness of the screen does not affect your eyes when you are using it in the sunlight. The super clear display of LG Optimus 4X HD is protected by LG's trademarked Corning® Gorilla® Glass, the same kind of glass that protect many of LG devices. The Corning Gorilla glass offers high level of damage resistance to the drops and scratches from daily usage.Even though the glass is damage resistant and strong, it is still highly sensitive to touch operations in the smartphone. Also, it makes it easy to clean this smartphone. It need to be noted that the Samsung Galaxy S3 has a slightly bigger screen (4.8 inches), which is not really noticeable unless you hold it too close.Design of Optimus 4X HDThe phone with a bigger screen make it easier to work or play on it yet slim enough to carry it with style. If I have to point out any drawback, it's the lack of ergonomic edges. The metallic double band edges, that look like 2 raised lines, do offer a good grip to hold the phone in hand, still not an attractive design for a high end smartphone. The LG 4X HD is available in 2 colors Black and white. When you look from far, the ridges on the side are very prominent. The hardware buttons in the black plastic are hidden between these metallic lines. (When I passed this phone around my friends for a general first look and feel they found the phone design with metallic dual line on the edge stylish and elegant.) Most of the visible part of the phone is made with premium plastic, which is very obvious if you look at the back of the phone. The grooves on the textured plastic give it good grippy feel and make it easy to hold. You can see the metallic LG logo on the back of the phone which is easily distinguishable from the black body.I am sure the first time you use this phone you will be really amazed the way you unlock it, although you have the standard screen lock types like draw pattern, enter pin, password and the facial recognition. You can touch at any part of the screen and then move your finger in any direction which create a circle around the spot which ripples outwards, gets bigger and bigger and then unlocks the phone. It is the same way you answer a phone call.Overall, the design of the 4X HD is stylish and elegant and can compete with any other high end smartphones currently on the market.Camera in LG Optimus 4X HDThe 4X HD comes with a 8mp back camera with a LED flash light and the secondary one on the front which is 1.3mp for having video chats. The performance of the camera in 4X is great in almost all situations. The flash is very powerful and can take flawless pictures up to 5 feet in low light condition. Here is a picture of a toy taken with Optimus 4X at low light condition with the LED flash:You can see a slight reflection of the camera flash on the object, but other than that the picture has come up well.Here is a photo taken using LG 4X HD in daylight:I am very impressed with the Panorama photo feature. Even though it is not a new technology, not many phones and cameras has an option to capture the picture in panorama mode continuously without repeated clicks. You click once and the 4X HD take over you can take the picture left to right or right to left and there will be an indicator at the bottom of the screen with the amount of the area you can save in a single Panoramic shot. NOTE: If you are going too fast the device will give an "Alert message : Too Fast" denoting that the user has to scroll at a gradual slow speed. There is a limit for taking a Panoramic image which will be indicated by the progress bar at the bottom which appears after you start capturing the image. It will start recording the picture from that angle. You move your camera slowly to cover the whole area you want to be captured and then release the shutter. It may take few seconds to process your pictures but at the end you will have a nice panoramic photo to share it with friends and family. Here is a photo I shot using the 4X HD phone in Panorama mode:Zoom options are at your fingertips and works very well. All of the camera settings in the 4X HD can be accessed from the touch screen and is very easy to figure out and operate. The volume controls doubles as camera shutter button which will make it easy to pause and continue while recording videos. Another feature in the phone is the "Time Catch shot" where the user can make a video and simultaneously capture still images at the same time.Video Playback in 4X HDLG has introduced some interesting features with the cool video playback application in the 4X HD smartphone. When the video is playing, you can zoom-in or zoom-out of the video without any Interruption while the video is being played. You can even pause the video and do the same without affecting the HD video quality. Watch a short video that shows the video and picture qualities of LG Optimus 4X smartphone:The Phone in 4X HDAt the end, this is a phone even though it allows you to do a lot more. What I care most in a smartphone is, it must be a "phone". The phone works really great in Optimus 4X HD and I never had a dropped call in my few days of testing. Sound clarity is excellent and works well even with speaker phone.LG Optimus 4X HD hands-on review - conclusionWith all top of the line features and stylish design, LG Optimus 4X HD is a great smartphone, all set to give a tight competition to the leading smartphones like Samsung Galaxy S3 and iPhone. LG has set the price correctly by making it below the price of Samsung Galaxy S3 price.
