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.
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 fluffLG 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.
Images of the LG G4 leak
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).
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.
Performance: Snapdragon 810 or Snapdragon 808?
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 problemsSkip 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
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.
Here is a summary of the new features in each version of LG's user interface:
|Version||Main Features||User Benefit|
|UX 1.0||Quck Memo, QSlide||Efficient management|
|UX 2.0||KnockON, KnockCode||Greater convenience|
|UX 3.0||Gesture Shot, Touch & Shoot||Easier and simpler usage|
|UX 4.0||Camera Manual Mode, Smart Notice||Personalized 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."

LG G4 price and release date
LG G4 will be unveiled earlier this year, on April 28thThe 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.
