LG Optimus 4X HD Review

Interface and Functionality:

LG Optimus UI is the name of the company’s Android interface overlay, and with Ice Cream Sandwich it comes in its 3.0 iteration. Thankfully, Optimus UI 3.0 hasn’t gutted the simple functionality of the Android Ice Cream Sandwich interface much, just replaced the stock icons with LG iconography to make the UI stand out, and added a few widgets of its own. Speaking of widgets, that Yahoo-branded weather one LG puts by default hasn’t received any design update, and it still as crude and rectangular as ever, taking points off the interface appearance. That’s a minor quibble, though, you can always get a slicker one, or replace the default launcher altogether with something prettier. More annoying is the lack of arrangement settings for the icons in the main menu. If you are used to arrange your icons in a scrollable, instead of paginated view, tough luck. If you want to arrange them alphabetically or by most used, no joy as well, you get to do it manually. The only option present is to condense the icon size so 30 instead of 20 of them fit on one screen. Oh well, you have to hit the Play Store again for a different launcher.

Yet you can now unlock the phone by dragging anywhere on the display, and the phone will show the underlying homescreen in the meantime. The four shortcuts at the bottom of the lock screen can be customized as well to take you into any app you please after unlocking.


Android 4.0 comes with a nice on-screen keyboard, but in this phone LG has somehow made it even better. It has put the brakes on the overzealous stock text prediction and has crammed the suggestions line a bit, so as you are not utterly annoyed when typing. Moreover, since the phone is narrow enough, one-handed typing is easier than on most other big-screen Androids.


There are a couple of new features that are worth mentioning, like Quick Memo, which has a toggle in the notification bar, and allows you to quickly doodle a note with your finger anywhere on the current screen, or on a portion of it you specify, and save it for reference, or leave your scribbles right there as crude reminders.
There are a lot of other media playback and camera feature enhancements, too, which will be paid special attention to in the next sections of the review. Overall LG Optimus 3.0 UI doesn’t muddle the stock Android ICS interface much, yet stacks a number of new features that make life with your phone easier.


Processor and memory:


Four cores humming along at 1.5GHz and a fifth “companion” core that kicks in for the mundane tasks like standby, music playback or interface navigation - you guessed it, it’s the 4-Plus-1 architecture of NVIDIA’s Tegra 3 processor.

The chip powers LG Optimus 4X HD pretty well, there is no lagging or hiccups, plus you get to play the specially optimized for this silicon games from Tegra Zone, a few of which like Shadowgun come preinstalled. The handset sports the usual 1GB of RAM, and is loaded with 12GB of user-accessible internal memory (16GB total), plus a microSD slot for storage expansion, which takes card up to 64GB in size.


Quadrant Standard AnTuTu NenaMark 2
LG Optimus 4X HD 3742 11184 52
Samsung Galaxy S III 5335 12016 58,6
HTC One X 4848 11024 47,4


Internet and connectivity:

The browser on the LG Optimus 4X HD is very smooth, with no hiccups while pinching, scrolling, tapping or panning around. Needless to say, it also supports Adobe Flash, so you can rest assured the full Internet experience will be upon you.

LG has introduced a pull up menu at the bottom, which allows you to zoom in and out by holding the center key and tilting the phone back and forth - an interesting to try gesture, but too skippy to be used on a regular basis.


As far as connectivity goes, the handset is loaded with 21Mbps HSDPA radio, Wi-Fi, Bluetooth 4.0, A-GPS, FM Radio, DLNA managed by the Smart Share app, and even NFC chip in the back cover, which takes a good use of LG’s Smart Tags, three of which - Car, Sleep and Office - are included in the box.

The device itself is very impressive and all, but most critics are on the software/support side at least with previous devices a user had to wait a very long time before a software update removed bugs/improved stability etc

in India samsung users hardly get any soft update.so we should consider this fact unless its a gingerbread.

I hope they prove me wrong. I have been a critic of LG smartphones for a long time. I really hope this ones succeeds, We need another Great competitor out there to mix up the the constant dominance of the "Big Guys"

Looks like an awesome phone. The third contender is in the ring! Your move Motorola, Apple and Sony, where is your HD Quad Core beast?

Well we can be sure that Apple's "Quad Core (processor) beast" is not coming anytime soon!

I'm sure the Xperia's with the s4 chip can rival the quad cores out there, with Sony's knack of producing the perfect optimization with their phones, i don't see an issue here

You guessed it... Apple's iPhone(Y) 5 will be quad core 800Mhz bwahaha... like their Original iPhone 4... 800mhz while the rest of the competition was 1GHz+. Consider Apple's Quad 800Mhz vs Samsung's Exynos Quad 1400Mhz which is the fastest chip around at the moment. :)

What will you do of clock speeds??. have dinner with them. The main thing is that the device should go smooth and Apple achives that Aim, and also lower clock speeds help save battery and Apple definitely suceeds in it

Thanks for the review. Its nice not to see any physical buttons. I'm guessing this isnt heading to verizon anytime soon?

Not having physical buttons can be a rather pain in the arse. One thing about being able to unlock a device on your desk at work by pressing the button is amazing. Not having to fumble around the top or sides... or in my previous Motorola Atrix's case bloody underneath... bad bad choices in functional form.

I mean it is rectangular? But this is how I wanted the SIII to look!

So far this is the one LG phone I'm interested in, The design is somewhat attractive to my taste. Now let the 3 way Royal Rumble between the Samsung Galaxy SIII, HTC OneX & LG 4X HD commence. .

8. Tjey007

probably the 3 best right now.for me s3 > one x >4x.

9. XiphiasGladius

Posts: 813; Member since: Aug 21, 2011

Hard to say on to which will come 2nd, to settle that would be like a coin flip, but s3 is arguably the better of the 3 in my opinion. LG's fall out was the waaaay to late software update of their flagship phones. Hope they straightened out that factor this year. . .

one x beats 4x but sIII smashes one x and 4x

Excellent phone. Great competition!

will this phone sell? yes of course it will. why? it is cheaper than the S3, has a regular SIM card slot (which removes the hassle of having to change the SIM card), expandable memory and removable battery. as the article said, among the 3, the 4x is the most versatile, and i'd take this over the GS3 anyday. this looks so much more nicer

Nuff said.

Awsome got more score than Htc one X. But its not about the score in the end personal preference is what matters. Continue your great work LG!

Finally!!...LG is listening...I would totally get this over the S3. The S3 is a great phone but it has too many features that I probably wont use on a daily basis. So this is the winner IMO between the One X and S3. I'm guessing it's cheaper that both and pretty much has everything. The 2 things to fix would be the annoying migraine inducing auto focus during video capture and timely updates. If LG can fix that then they definitely have a winner. They might also want to improve their marketing. I guess that's 3 things they need to fix.

Have read a couple other reviews and this one. The phone is nice on its own, but when compared to other top flagships, it will probably be in fourth or fifth place. There's very little reason to get this phone other than for its design and maybe its compactness, which I find quite enamoring. It's a shame that Samsung's Korean rival still hasn't got their smartphone battle plan in order and instead is just content with poking it's head above the clouds to glimpse the view without actually breaking through. The all plastic design follows the same faux-leather texture back which I have never liked and now there are TWO prominent chrome rims sticking out. If it was a solid metal maybe, but it's undoubtedly some cheap breakable and squeezable plastic that you have to hold onto. LG hasn't touted any polycarbonate or such, no kevlar, or glass, so materials don't sound too enticing. LG may also win awards for their LCD tech, but why does the HTC One X have a more impressive screen with the laminated glass and painted on look? Other reviews have mentioned this, but the LG screen has a comparatively thick sheet of reflective glass that you can clearly see in the video tour. Coupled with the thick and unpleasant black border that gives it an old phone or budget phone vibe, the results are not very impressive. Then there is the simplistic UI with large, stretched looking fonts and icons. It looks more like a 800x480 budget display and single-core Froyo innards than its actual 720p goodness and quad-core ICS freshness. Changing the fat looking font and its size, as well as making the icons more compact and less stretched out looking, decreasing the size and increasing the number on-screen, would improve the look and feel drastically. Ditto for transitions. Why LG cannot understand these basic basic concepts, I do not know. The screen brightness issue also seems like something more suitable to an early prototype than a retail product. The camera doesn't really look better than their old 8MP ones. Actually, it is similar to the HTC One X. They both lack shades of anything, losing significant detail, and instead opt to smear everything in solid colors, giving pictures a cartoony look. The One X oversharpens more and is much darker. The Optimus 4x brightens far too much. Both are more like instagram pictures than real ones. Then there is the video capture. Audio is quite stellar sounding, and the framerate is smooth, including exposure. But the video has the same cartoony shadeless solid color look of the still images, and if it wasn't obvious from the videos, a very serious issue with focusing. A quick search through youtube will find that this is not an isolated incident, and all video exhibit this epileptic refocusing eye dilating problem, which happens every few seconds. How something so blatantly broken like this got rubberstamped and tested by so many people is probably the 8th wonder of the world. Neither benchmarks, battery life, nor performance is a
