Duel of smartphones: Galaxy A5 (2016) / LG G4
....... Let's start this duel the most important element of a smartphone display. The Galaxy A5 and LG G4 do not play very much in the same court. The Samsung in mid range sports a reasonable slab 5.2 inches while the G last year embarked a massive 5.5 inch screen. We do not départagerons both moving on this, as the size of a smartphone is a matter of taste. In terms of raw results, the G4 takes a slender lead over its fine display with its definition WQHD (2560 x 1400 px) and 534 pixels per inch, against the 424 ppi Galaxy A5 conferred by its Full HD screen. That said, you have bionic eyes or specific needs to see a real difference. On the colorimetry plan in hand, the Samsung mobile comes off more sharply with a Delta E of 1.8 against 3.3 of the G4 - though, again, the difference is imperceptible to the eye. The temperature is also better on the A5, as the latter reaches 6900 Kelvin 7845 K against the LG mobile. But where Samsung really widens the gap, it is with the Amoled technology A5 face the screen IPS G4. So even though the G4 enjoys an excellent contrast ratio of 1546: 1, it does not compete with the virtually infinite contrast A5. Another advantage of AMOLED, ghosting is virtually nil while the G4 it reaches 18 ms. The touch delay is more or less equivalent, with 87 ms on the A5 against 100 ms on the G4. The A5 thus wins by a short head, especially through the adoption of AMOLED, beautifully mastered by Samsung since a couple of years.
