Dear All I have two Ipad Air 2 (Wifi Only) 64Gb models in my family out of which one was purchased just a month earlier before the second one. However i noticed that the brightness levels are different for the two ipad airs. Where the one purchased earlier is slightly on a lower brightness side. I tried to check it both ways by keeping the brightness on maximum level as well as minimum level and the earlier purchased ipad air's brightness was found to be lower in both the cases. However the brightness is difference is very minute and it can be seen only if you observe very minutely and therefore not a glaring difference. Also the white screen on my earlier purchased ipad doesnt exactly look white as on the newest ipad. It does not even have a yellow tint or anything of that sort. But the white looks a little dull. Both ipads running on same ios 9.1 and have the same Model numbers. Also i havent used much my earlier ipad in that one month as i was very busy and have used only once or twice in a week for just half and hour or so and for the rest of the time it was switched off. If that makes the difference since i havent used it to its capabilities and the other ipad has been on since it has been purchased. As i said the difference is hardly noticeable like just 1% may be not much but is it an issue?? Or is it just in my mind!!! Guys please help!!!!! Thanks!!!
