LG G4 rumor round-up: leaked images, performance, price and release date

The LG G4 rumor mill has been churning information at full speed ahead of the expected official announcement of LG's new flagship. We already have an official announcement date: it's April 28th, and in anticipation of the big unveiling, it's time to start rounding things up ahead of the big launch.

LG G4 rumors so far agree that it will bring improvements a few key areas: build materials as all teasers suggest LG will offer a genuine leather version of the G4 in addition to the more traditional plastic model; the camera, as the new G4 is expected to feature a fast, f/1.8 lens sitting on top of a 16-megapixel camera sensor; and a brand new user interface in the form of LG's UX 4 with livelier, fresher colors and Android 5.0 Lollipop as the base.

What else will we see in the LG G4? And could it steal the thunder from the hottest phones right now: the Samsung Galaxy S6, the Apple iPhone 6, and the HTC One M9? Let's find out.

Design and display

Initial rumors about the LG G4 having a very slightly curved screen, seem to have turned out true, but don't expect a curve as noticeable as the one on the LG G Flex 2. Instead, the G4 is expected to feature a very subtle, 3000mm radius curve. This will likely not have any huge ramifications to usability, so it's just an interesting visual touch.

5.5-inch Quad HD display, but increased color gamut seems like marketing fluff

LG has also officially released a brand new 5.5-inch Quad HD (1440 x 2560-pixel) LCD display panel right before the G4 unveiling, boasting about it being "a quantum jump in terms of key features, including color gamut, brightness, contrast ratio, touch function, power consumption and thinness." What does that mean? LG explains that the screen will have a 120% color gamut, a 50% higher contrast ratio (supposedly, from earlier model) and it's 30% brighter than most other displays. We don't have the tiny details, but it's worth remembering that adhering to color standards is what makes a display look actually great, and in this train of thought, having a 120% color gamut than the standard 100% is not something to brag about, as it will make for inaccurate, overblown colors. It seemed like such marketing fluff was in the past when companies like Samsung bragged about having wider color gamuts (the Galaxy S6 display, for instance, now adheres to the standard 100% sRGB color gamut, which makes its colors look truly outstanding), but unfortunately, the G4 seems set to take a step backwards in this regard.

We've also seen LG advertize an 'IPS Quantum' display, all seemingly marketing terms for the aforementioned features.

Most importantly, the expected dimensions of the LG G4 have leaked out as well. The phone will be slightly taller and wider than the G3 (take a look at our size comparison below for the actual numbers).

5.86 x 3 x 0.39 inches
148.9 x 76.1 x 9.8 mm
5.47 oz (155 g)


5.76 x 2.94 x 0.35 inches
146.3 x 74.6 x 8.9 mm
5.26 oz (149 g)


5.45 x 2.79 x 0.35 inches
138.5 x 70.9 x 8.9 mm
5.04 oz (143 g)

No fingerprint scanner after all?

A fingerprint scanner seems like an inevitable feature of modern day flagships by Samsung and Apple, as the two companies have integrated full-on payment systems dependent on that new scanner. Other phone makers like LG and HTC seem to ignore those new developments and simply do not provide the option for a fingerprint scanner.

Early rumors out of Korea suggested that LG might change that course with the G4 and the company was even rumored to be working on a phone-based payment system of its own breed, but latest leaks show that the LG G4 will not feature a fingerprint reader. Even if LG is planning on rolling out some form of a payment system, those plans will likely be pushed further down the road.

Performance: Snapdragon 810 or Snapdragon 808?

LG G4 rumor round-up: leaked images, performance, price and release date
We've been hearing about LG working on its own system chip for years now, but it seems that early rumors all agreed that the LG G4 will run on Qualcomm's Snapdragon 810.

The octa-core Snapdragon 810 is a 64-bit chip using four Cortex A57 high-performance cores and four Cortex A53 energy-efficient cores in a big.LITTLE setup. Those four cores, however, tend to get really hot, unless you cap their performance. And if you do, you lose a lot of the performance gains.

Hexa-core Snapdragon 808 might be a safe bet to avoid overheating problems

Skip forward to recent days, and we have the first leaked benchmark runs of the LG G4, where it is - surprisingly - listed touting a Snapdragon 808 system chip. The Snapdragon 808 is another SoC in Qualcomm's all-64-bit new lineup, but rather than having four high-performance (and high-heat) Cortex A57 cores, it features only two of them along with the four battery-savvy Cortex A53s. The GPU in the Snapdragon 808 is the Adreno 418, a graphics chip that is 20% faster than the Adreno 330 found in the Snapdragon 800/801, but still behind the Adreno 430 and Adrenoe 420. Overall, though, it's clear that the Snapdragon 808 should be a bit behind most 2015 flagships in terms of pure performance. Good news is that this suggests that the LG G4 will also continue LG's tradition of being more affordable than top-tier phones like the Galaxy S6.

LG has set a precedent with last year's flagship G3 sporting 32GB of internal storage (twice more than the usual 16 gigs), and we expect this good tradition to continue in 2015. We've also heard rumors about the back cover of the phone being removable, which could mean that the phone will support expandable storage via microSD cards.

Interface: a taste of Lollipop with a brand new LG UX 4.0

In order to make full use of the 64-bit Snapdragon 810, the LG G4 has to run on the latest Android 5.0 Lollipop, and - of course - it does. The system is said to be overlayed with LG’s updated UX 4.0 custom skin.

LG has officially unveiled the new UX 4.0 before the announcement of the LG G4, so we now have all the official details. The flat style of the interface remains, but it has become a bit more colorful. LG promises some big changes, and the one we're most excited about is the improvement to speed: UX 4.0 should run smoother, a change that is particularly needed given that the LG G3 had a noticeably stuttery performance.

LG also introduces neat new features like Quick Shot that allows you to double-tap on the rear home key to start the camera swiftly from any app and even when your display is off. Inside the camera, you now have not only the all-auto mode, but three modes: Simple, Basic and Manual. The manual is the one we're most curious to see (hopefully, it gives control over shutter speed and ISO for a full manual ride).

As a whole, UX 4.0 learns more from your routines, making the Smart Notice smarter, and the information is far more relevant. So, if you are a runner, the notification will offer the weather forecast as well as additional tid bits like, “Perfect time to go for a run.” Unique customizations continue from there where the UX 4.0 will also assign a unique ringtone ID for every caller that is in your favorites list.

Here is a summary of the new features in each version of LG's user interface:

VersionMain FeaturesUser Benefit
UX 1.0Quck Memo, QSlideEfficient management
UX 2.0KnockON, KnockCodeGreater convenience
UX 3.0Gesture Shot, Touch & ShootEasier and simpler usage
UX 4.0Camera Manual Mode, Smart NoticePersonalized user experience


The LG G4 will feature a 16-megapixel main camera with a fast, f/1.8 aperture lens and an 8-megapixel front-facing camera. LG emphasizes the wide-aperture lens and all the light-gathering advantages that it brings, so we're looking forward to the G4 being a great camera for low-light shots. The 8-megapixel resolution of the front cam is also above most of the competition, and while resolution is not equal to quality, it does suggest higher amount of detail. LG boasts that the selfie cam features an ultra-thin IR filter to keep infrared light from entering the camera lens, and sets expectations for images with "more natural and accurate colors."

Three new modes in LG G4 camera

The camera can be started from within any app (even the lock screen) with a double tap on the rear key, and it packs a simple, basic, and manual modes.

As a quick flashback, the LG G3 arrived with a 13-megapixel camera with optical image stabilization, and with the rear-positioned keys, using it was quick and easy. The same ease of use will be preserved in the G4. The quality of the images on the G3 was very good, but a step short of excellent: detail was a bit smudged and images tended to have a slight yellow-ish tint, and those are two issues we hope to see fixed in the new LG G4.

LG G4 battery

The LG G3 was not a stellar performer when it came to battery life, and the chief reason seemed to lie in the demanding Quad HD screen that was much more taxing on battery life than previous, 1080p displays. In the G4, LG is expected to use a 3000mAh cell, the same size as in the G3, but hopes are that the company has worked out some of the kinks of Quad HD and optimized software to run with less strain on the battery.

LG G4 price and release date

LG G4 will be unveiled earlier this year, on April 28th

The LG G4 announcement date is now officially set for April 28th when LG will hold events in six of the world's largest cities: New York, London, Paris, Istanbul, Singapore, and Seoul. It's interesting to note that company executives confirmed that LG will follow the G4 up with another high-end smartphone in the second half of the year.

The LG G4 actual release date in stores is not clear yet, but we'd put an informed guess that it will be around a month after the unveiling - in late May or early June.

The LG G4 price should also follow the example of last year’s model, and this means that the G4 would be more affordable than the Galaxy S6 and iPhone 6, its main rivals (we expect a price of some $100 on contract, or around $550 off contract). Some reports, however, do claim that using genuine leather would make the device more expensive than before, so we could see a heftier price tag on the leather version, in particular.

Okay, now I feel better about the G4.

Let's hope the increased size is due to the fingerprint scanner but still maintains the same 5.5" screen size.

To be honest though, I really hope they improve upon the overall quality of the design. The G3 has a great design, but I know they can do even better, especially with the back of the phone.

...... LG’s mobile chief Cho Ju-no. The executive also revealed the news that this year, LG will follow the G4 up with another high-end smartphone in the second half of the year....

i think this would be the REAL DEAL!

i dont feel better about it that crappy 810 powering a qhd display is going to have horrible performance.

You are just biased or stubborn. The note 4 had no issues with that boring exynos or the regular 805 snapdragon. The 810 is better than both those, maybe not as good as the new exynos the S6 uses, but its a lot better than last years cpu's. It won't have horribly performance. The exynos will just run faster on paper, but in reality both will be fluid. Deal with it.

it has over heating issues and will under perform because of it. because the only way to over come the issue is to lower the clock speed of the cpu it will be no better than a 805 after that. the 810 is awful.

Clockspeed not, performance will. It's true, the 810 is bad but still way better than 805

It's a very big tossup as to which is better. Based on some of the battery benchmarks it appears tht the 805 might actually still be the better chip for a QHD display.

That being said it seems that the G4 will use an 808 chip based on the article, that has 64 bit support but in terms of graphics capability it will be behind the 805 chip. It does seem to be a better compromise give that the 810 seriously blows.

If this phone was a slight bit more compact and used a 1080 screen it would be much better. I'm really not sold on the 1440 on a sub 6" device.

The article makes it seem like it will have the 808 not the 810; pocket now also said that leaked info suggests an 808 chip.

I like more design of G2. I think its best screen to body ratio till today. Those slim bezels are awesome.
It is still phone with perfect size for me, just wish they went with side buttons not rear. I was never able to get use to those rear buttons.

The G2 was one of the best phones I ever used. Going from a G2 to a Note 4, I have come to appreciate the larger screen, removable battery and SD storage.

I hope the G4 has a 5.7" screen with thinner bezels than the Note 4. Beating the Note 4 camera will be a challenge.

It's called the Nexus 5. They had to shrink the screen to put the buttons on the side though.

I think this phone will be nice. But I guess I have to wait and see. So far the Note4 will do.

Not happy about the size. If it's true I'll have to pass. I prefer the size of the G2. I think that is perfect.

I will not buy a phone any wider than 70mm. 67mm wide is the "sweet spot" for one-handed operation.

If they have a removable back cover + uSD expansion, they will have a huge one up against Samsung. For a change HTC and LG will be more flexible than Samsung which has never happened till now.

Agreed S810 might be less powerful than Exy 7xxxx but a lot of last remaining goodwill towards Samsung has been taken down by their latest decision with S6.

I lost faith in LG... Don't get me wrong I had a great time with my LG G3, however, I noticed the infamous hairline cracked next to the USB and Headphone Jack... Thank GOD! I was able to return it, and get my money back on Amazon... I am glad that I have chosen the S6 for this year... So... NO THANKS!

Well, at least they've addressed the problem and are not denying it:

Things like these happen sometimes for all manufacturers, but as long as the manufacturer addresses the problem and corrects it then it's fine.

LG admitted it was a fault and you can get it fixed for free, what more do you want? Your loss if that happens to your S6 or other manufacture fault, coz Samsung won't man up and admit faults. HUGE RESPECT to LG for actually caring and fixing instead of blaming the users or saying there is no fault.

LG always trys to compete more against Samsung than Apple. If they wanna beat Samsung, they have to step up their game by putting their WOLED display tech into their highest-end models. LG could lead on resolution game on smartphones(not that Samsung can't produce em, they just don't put em on their individual and commercial smartphones, yet) but they have always shown their weakness a lot in brightness & color reproduction categories. I haven't used it myself, yet but I love the sound of LG's laser focus feature. But there's nothing to be greatly admired in G3's picture quality. Also, now that Samsung went metal, LG should follow that 'No Shame/Not Copying' trend. I know they have many good ideas and designs but they need to organize & execute em well together and truly put out only what consumers really want on their highest-end models that are directly competing against the highest-end Galaxy lines & of course apple. LG can't compete against Chinese in the lower-end market. They or anyone else can't compete against Samsung this year's soc battle. So forget about those two for this and next year but keep working hard on making their own soc design, at least. Premium feel and best screen in the market & critically much needed design's 'WoW' factor should give em a fair start.

1. These are just rumors.
2. The LG Mobile chief said the G4 will be radically different than before. Also, where is the new fingerprint scanner they were talking about?
3. The new renders are most likely a g flex 2 variant or some kind, as even the thickness is almost the same (9.9 vs 9.4mm).
4. There is no way LG would use the same design over again because the G3 changed quite a bit from the G2 and G2 from Optimus G, so we know that LG is capable and not afraid to change their designs up each year.
5. After seeing the S6 and the bad receptions of the M9, LG will definitely not risk pulling and Apple and HTC. They said this year they will strive for the 3rd biggest global phone manufacturer.

What's up with that pic? Are they going to really use leather as a back? Alot of the stories I've read from Moto X users about a leather back has been negative and most say they wished they went with wood instead.
