Camera comparison: LG G3 vs Samsung Galaxy S5, Galaxy Note 3, iPhone 5s, LG G2, Sony Xperia Z2, HTC One (M8)
So, it turns out that the LG G3 has no troubles with taking photos in a low-light, indoor environment. Details in such images are plentiful, and the digital noise is within the tolerable limits, visible only once we zoom in. Colors are accurate enough even when the LED flash has fired. The dual-tone LED setup is bright and fills the entire frame with light from up to several feet.
This is also a case where the Xperia Z2 performs almost as well as the LG G3. Sony's phone captures details really well and its flash has a very natural tone, despite being of the single-LED kind. The LG G3 outperforms the Z2 only in the darkest scenes with its superior detail preservation.
Then there's the iPhone – an all-around great performer. Again, having just 8MP to work with, it struggles to provide as much detail as, let's say the S5, G3, or the Z2, but nevertheless, we are quite happy with what we see. The iPhone's indoor images look very detailed given the camera's resolution. Color-wise, we do see a boost in warmness and brightness, but in this case, there's nothing too worrying about this. As for the phone's flash, the True Tone LED flash produces warm light that easily lights up the scene, but it fires only in very low lightning situations. Scenes that aren't dark enough to force the flash to fire may end up quite noisy and low on detail. Take a look at our low-light sample in the studio to see what we mean.
Photos from the Samsung Galaxy S5 and the Samsung Galaxy Note 3 have plenty of detail, there's no denying that. Where the two snappers fall short, however, is color accuracy when the flash is in use. Their images are clearly colder than those from the other phones, which renders them somewhat unnatural.
Indoor photos from the LG G2 look quite good, rivaling those from the G3 when it comes to details. But that's valid only as long as there's a good amount of light available. As lights get dim, the presence of digital noise becomes apparent and details also suffer heavily because of that. The G2 has a strong LED light that won't throw color fidelity out the window. It won't fire, however, unless light is really scarce. That's why you might need to force it to fire on certain occasions.
Due to its lower camera resolution, the HTC One (M8) can't provide as much details as the rest of the phones being compared. Color accuracy also leaves lots of room for improvement – colors are dull and lifeless, with a pink-ish hue in darker scenes. On the other hand, the HTC One (M8) took the best-looking photo in complete darkness, with very natural colors and scene filled with light.
