LG G4 First Impressions
For the original German preview, see here.
The product manager's presentation of LG's new G4 flagship smartphone was strongly focused on the new cameras. The invited guests - including us - had the opportunity of getting an impression of the prowess of the South Korean manufacturer's 5.5-inch top model at the event. The engineers have apparently poured heart and soul into the field of photography. Multiple optimizations have been made compared with the former G3 that also excelled with good camera equipment. Ambitious photographers will be pleased about the manual mode that gives the user full control. More about that in the course of this preview and naturally in the in-depth test report coming soon.
The screen has also been modified. Although its size and resolution are the same as in the G3, LG now speaks of a "Quantum IPS" screen that is allegedly absolutely superior to the screen in the G3, and especially in terms of brightness, contrast and color accuracy. It was already obvious that it is very bright at the presentation.
LG's new premium model is to cost 700 Euros (~$761). However, its removable back cover is genuine leather. The phone costs 50 Euros (~$54) less when plastic is enough. Micro-SD is presently included as a bonus on early pre-orders.
First Impressions
No question: LG's G4 stands out from the current trend of absolutely flat premium-range smartphones comprised of glass and metal. We find that good. The laterally and longitudinally curved casing has considerably more height at 9.8 millimeters than all flagship rivals, but it is extremely pleasant to hold - particularly when it has been ordered with the genuine leather back cover. It might cost 50 Euros (~$54) extra, but it is worth every cent. The plastic cover is also in the box. LG's G4 is not only an eye-catcher with the leather cover, it also has an extremely high-quality feel. Of course, leather is more susceptible to scratches than, for example, sapphire glass. However, it will tell its own story in the course of its service life. Anyone who has ever owned a raw leather product will know what the author means. The weight of 155 grams is also within limits. Overall, LG's G4 makes a relatively compact impression despite it 5.5-inch screen. Apple's iPhone 6 Plus is, for example, almost a centimeter longer at the same display diagonal.
LG's G4 not only looks good and has a pleasant feel, though. Its stiffness is also decent, and the removable back cover enables replacing the battery. LG is now alone with that in the premium range and proves that high-quality feel does not have to exclude a removable battery. The SIM and micro-SD slots are also under the cover. The latter theoretically supports cards with a storage capacity of up to 2 TB. For the record: The casing of LG's G4 is the best of its kind - and it is out of the ordinary with its leather back to top it off.
Cameras & Multimedia
The cameras are probably the most interesting feature of the new G4 - at least according to the manufacturer. However, even objectively, the South Korean company has put a lot of effort in this aspect. Not only has the resolution of 16 MP on the rear and a "selfie suitable" 8 MP on the front increased considerably compared with the precursor. LG has improved both the lens size and the maximum aperture to f/1.8. Then there is the optical image stabilizer OIS2 that can now correct deflections of up to two degrees on three axes, a manual mode with extensive settings, and helpful control options. For example, the front camera shoots four selfies in succession via hand gesture. If it has to be fast, double tapping the rear-sided volume down button immediately triggers a shot - even from standby. According to LG, the entire procedure only takes 0.6 seconds. We can say after a few tries: We believe it. More information about the technical innovations regarding the cameras will be published in the in-depth review.
A first look at the image quality: Some pictures were shot during the G4 event - indoors in rainy conditions and approaching twilight. However, the light-sensitive lens shows its prowess here. The pictures are still exposed perfectly and also sufficiently focused in the normal size. Graininess is first seen in extreme blowups. The colors look natural and in no way overly gaudy. The image quality even improves visibly in bright surroundings. They are more dynamic, and the level of detail is higher. Thanks to the high maximum aperture, it is also possible to tinker with the focus. In any case, we are curious about the other features of the cameras in the G4.
Display
A glance at the screen's tech specs suggests that LG has not changed anything. Why should it? A WQHD screen should suffice. In fact, both the size of 5.5-inches and the resolution of 2560x1440 pixels have not been altered. However, the screen is a completely new generation from the South Korean manufacturer. The marketing term "Quantum IPS" conceals a panel that is to display improvements in all key specs, owing to a modified production process. We could convince ourselves of that in a short time. The brightness, black level and contrast have been improved considerably compared to its precursor. All rates are on a high level. The brightness of considerably over 500 cd/m² is easily high enough even for outdoor use. Unfortunately, the G4 dims the brightness after a short while of heavy usage - a condition that we also criticized in the precursors.
The color accuracy of LG's G4 is slightly worse than that of the G3. The shifts in the grayscale level and mixed colors in relation to the sRGB reference are still somewhat too high. However, that will not adversely affect everyday use. LG's G4 covers the DCI color space (Digital Camera Initiatives) by 98% according to the manufacturer. Since this color space is shifted a bit more to blue and red in contrast to sRGB, it at least explains the deviations in color accuracy to some extent.

Performance
Unlike the premium range contenders, LG does not use the latest top model of its SoC supplier. That would currently be Qualcomm's Snapdragon 810 with eight cores. The Snapdragon 808 is installed in the G4 instead. Although it utilizes the big-LITTLE design like its big brother and fuses two processing cores, it only has two powerful Cortex A57 cores in contrast to the four in the 810 model. The four energy-saving cores, type Cortex A53, are the same. Qualcomm's Adreno 418 is integrated into the SoC, which also cannot compete with the bigger 430 brother. This decision is somewhat incomprehensible especially when considering the extremely high resolution, and even more when LG's statement that the waste heat could not be controlled has been contradicted.
Our first benchmarks also show that LG's G4 is inferior to some comparison devices in almost every sector. LG's 4 can only defeat its precursor and the soon to be replaced Sony Xperia Z3 in the synthetic benchmarks Geekbench 3 and AnTuTu v5. The premium models from Samsung and HTC are beyond reach. It looks similar in the graphics-driven tests. The G4, however, still has an edge on Apple's iPhone 6 Plus in 3DMark 2013 Ice Storm Unlimited. The GFX benchmark also locates LG's G4 behind the leading group. The off-screen results still look very promising. However, the reality is on-screen, and the Adreno 418 struggles quite a bit with the high resolution.
The performance of the internal flash memory is a plain and simple "very good." Only Samsung's Galaxy S6 (Edge) plays in its own league here. The browser performance is also impeccable although our sample lags behind the leaders. Subjectively, LG's G4 proved to have an absolutely sufficient performance after the first few hours of use. We will deal with high-requirement games in the in-depth review.

Energy & Battery Runtime
The battery of LG's G4 is removable, which is very good news. The lithium-ion battery can also supply a relatively high amount of energy with 11.55 Wh or 3000 mAh. In contrast to the precursor, the power requirement has changed slightly. Although the G4 consumes less power than the G3 in both maximum idle and during load, that is the opposite in the partial load sector. We therefore presume that the real-life battery life will be a bit shorter. The G3 was not an endurance machine, either.

Preliminary Verdict
We were very anxious about the test of LG's G4 in the run-up - and we still are. The South Korean manufacturer's new flagship could in fact keep most of its vaunting promises. Primarily, the superb camera equipment that will again have the opportunity to show its prowess in our extensive tests.
LG's G4 is well on the way to becoming the new camera reference among smartphones. Both hardware and software are well-conceived and their implementation is first rate.
The casing is also unmatched. The interplay of selected materials, looks and functionality are simply balanced. Lighter and thinner smartphones naturally exist, but none fit in the hand as comfortably as LG's G4 at present.
LG slightly slows down in performance. We believe uncompromising performance is not always the most important thing and the Snapdragon 808 seems to be a good choice... if it did not involve the somewhat weak GPU that will still have to show its capabilities. It is also very annoying that the screen's brightness is again visibly dimmed after a few minutes during games or benchmarks - which has likely developed into a bad habit at LG.
