The Build number on your Android phone is in a different place on every phone, but it's easy enough to find. That's right: seven times. After a few taps, you'll see a small pop-up alert telling you that "You are now X steps away from being a developer" with a number that counts down with every additional tap. After the seventh tap, a message will appear telling you that "You are now a developer! Some phones will include a general message about tinkering with your Android phone, but you can simply tap OK.
While many of the options are strictly for developers, including things like USB debugging and bootloader unlocking, you'll also find things such as high-fi audio codecs, notch options, and CPU usage among the toggles. Experiment at your own risk. While Google used to require a factory reset to rid your phone of Developer options, it's easier to jettison now. The screen will gray out, and once you leave, it'll be gone from your phone.

To get it back, you'll need to follow these steps again. As a result, black color is indeed black, and other colors are more straightforward to control without using complex filters and color control technologies such as Quantum Dots and Nano Dots.

In general, higher brightness is preferred to read the screen content on a sunny day or bright environment.

Higher brightness leads directly to better image quality in widespread situations. Frankly, we think that the company was right all along because ultra-wide is just so much more useful than a 2X zoom which equates to moving forward by about 3 feet. With LG V40, you get it all: standard, zoom and ultra-wide lenses in the primary camera system. We really wondered if LG or Huawei or Nokia would be first to market with this, but now we know: LG kicks the door with the triple rear cameras and we could not be happier about it. This is what we wanted all along: excellent classic camera capabilities, couples with ultra-wide and zoom.
In bright daylight, 16 MP cameras such as the OnePlus 6 can capture a bit more details, just as our technical analysis below predicts.
We noticed that the LG V40 has a slight disadvantage for background details sharpness. LG has also increased the color saturation and contrast a little bit by default to make images more appealing. In low-light photography, we pitted the LG V40 against the leading low-light cameras all tests shot at 5 LUX brightness. To achieve this, the V40 uses a larger aperture, and some image processing but without going overboard.
For some reason, the iPhone XS was a little off with the color balance, giving a warm tint. The Galaxy Note 9 has a slight advantage in low-light with an image that as a bit clearer and less noisy. V40 also has more image processing. You can look at the cropped images below and zoom on the details:.

Note that LG has an extra-bright mode that also uses Pixel Binning, and the image above was shot without it. Pixel Binning would bring the resolution down to 4 MP, but it can be beneficial under extreme low-light conditions. The Huawei P20 Pro easily outclasses both competitors.
Although the LG V40 zoom photos are still much better than less expensive phones, the battle for supremacy at the high-end is difficult. P20 Pro aside, the Note 9 has a great mix of noise and details, while the iPhone has a bit more details but with too much noise. Note that this is an extreme zoom situation 10X to push the camera to its limits.
The more moderate the zoom, and the harder it is to notice these details. Because the LG V40 offers so many different focal lengths, the company has included a real-time thumbnail review of each lens in the camera app. Just tap and hold the lens selector at the top, and the preview will kick in.
What a neat feature, we love it! The 12 Megapixel resolution should not be used as a general proxy of photo quality, but on a sunny day, it could be a useful metric for photographic detail and sharpness. For example, on a sunny day, a landscape photo with a higher megapixel count could show finer details. Also, the physical size of each sensor pixel is essential. With higher megapixel counts, sensing pixels sensels may have to be smaller.
Each obtains less light information and in dark situations, it is better for the overall image quality to gather more light with fewer but bigger sensels than the opposite. It is a balance that needs to be found. Today, 12 Megapixel seem to be the best sensor trade-off between sharpness, low-light and autofocus performance. The presence of an Optical Image Stabilization OIS module on the primary camera increases the odds of capturing sharp images in daylight, and brighter images at night.
OIS helps to achieve better image clarity and higher low-light performance by offsetting minute hand-shaking motion.

OIS makes it practical to leave the shutter open longer to gather more light more prolonged exposure. Optical and digital stabilization are completely different, with digital stabilization suitable to improve video recording smoothness. This handset supports Electronic Image Stabilization EIS , which is specifically designed to stabilize video recording from excess motion induced by hand-holding, walking, running. Road vibrations or drone flight turbulence could also be offset by this technique. Certain video formats such as extreme resolutions or frame rates may not be compatible with this device EIS capabilities.
The auto-focus of the V40 camera is based on Phase Detection technology.

Then it got integrated into the camera image sensor. It works by adding specialized AF pixels sensors that would tell if specific points in the image were in-focus. This method is swift and the AF capabilities work well in most cases. AF performance is more or less proportional to the number of hardware AF sensels. Typically this number can go from dozens to hundreds of Phase-Detection AF points.

Fortunately, the mobile design team has listened to user feedback and came back with a brand new, more powerful, dual-lens selfie camera. The 8 MP selfie camera comes with a standard 26mm focal-length comparable to the main rear camera. The secondary 5 MP selfie camera has a wider angle 21mm and should decently in bright light situations. The main advantage of the dual selfie camera is to add a more accurate Bokeh mode background blur, or portrait photography.
LG also lets you change the blur amount after taking the shot, which is always nice. The battery capacity of the V40 is mAh , which is very good in general, and slightly below-average in its own category. Battery life is one of the most sought-after features of a handset.
