Like every other budget Samsung phone, there is no ambient light sensor on the Galaxy J2 ( 2016) , an omission I have already complained about in a recent post. Samsung does, however, let you change the display mode, similar to how you can do it on costlier Galaxy devices.
There are Adaptive Display, AMOLED cinema, AMOLED photo and Basic modes to choose from, with Basic being the most accurate and also the most yellowish. Don’t bother changing the display mode though, as you really need to be on the default Adaptive Display option to get the best out of the J2 ( 2016) ’s Super AMOLED panel.
