LG Optimus 4X HD Review
The dual noise-canceling mics on the LG Optimus 4X HD did a good job taking out the ambient fluff while we were talking, and the other party said they could hear us loud and clear enough. On our end the sound in the earpiece was just average - neither very strong, nor overly clean, with a bit of an echo, but we could tell the speaker’s voice and didn’t have trouble hearing them fine two notches below maximum volume.

A new SiO+ technology has been used for the battery, says LG, and the change occurred after the handset was announced. This allowed the capacious 2150mAh juicer to pack more lithium ions in less space, making for the compact body it’s in. The battery is quoted for the way above average 11 hours of talk time in 3G mode.

In our daily grind with the handset we did notice that the screen seems to consume much less energy than the 4.5” HD one on the Optimus LTE, for example, but power consumption in standby is pretty significant with Tegra 3, compared to the Snapdragons. Thus despite the large battery you won’t be able to squeeze more than a day and change with power use.


The LG Optimus 4X HD is undoubtedly the best Android smartphone that the company has produced to date. It covers the geeky ground with a quad-core Tegra 3 chip, large and vivid HD display and the latest Android 4.0 out of the box.

The design is simple and pleasant, with a few welcome twists that make the phone a looker from the prism-shaped sides and easier to grip. The handset is more compact than its main rivals this Android season, despite being crammed with the same high-end innards, making it easier to operate with one hand. The only complaints are its preset screen brightness management and the funky camera focus, so hopefully these will be addressed with the first software update.

The new LG Optimus 3.0 UI is an improvement over its predecessor with a number of new features like Quick Memo and a very functional lock screen. Video playback is vastly improved with the new Media Plex features like live video zoom, and the camera module has been given new abilities like the Time Machine precapture. Nothing groundbreaking, but coupled with the light and quick ICS, the UI overlay feels sufficiently enhanced.

Whether or not LG’s best Android effort to date succeeds will be the market’s decision, as it stand against some pretty hefty opposition. The HTC One X has very similar components, but more stylish unibody design, yet all is for the sake of expandability, as it has a sealed battery compartment and no memory card slot.

The Samsung Galaxy S III also sports powerful silicon, but is with a more distinctive design and a slightly larger Super AMOLED HD display, not to mention the better camera. Yet the LG Optimus 4X HD offers the most flexibility out of the three flagships in this price range with its regular SIM slot, removable battery and expandable memory, so if that’s your thing it’s an easy pick.

Software version: IML74K

LG Optimus 4X HD Video Review:


  • Most compact of the Android flagships
  • Carrying regular SIM and microSD slots, plus a removable battery
  • Handy new features like Quick Memo (note taking), Media Plex (video playback) and Time Machine (frame precapture)


  • Fiddly camera focus
  • Automatic brightness adjustment only works from a preset baseline

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

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.

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. .

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. . .

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

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
