I am trying to get the maximum brightness possible out of my iPad air so that I can see it better outdoors in direct sunlight. I have turned auto brightness off, and moved the slider all the way to the right... BUT whenever I swipe up from the bottom of the screen and adjust the brightness that way, the screen is MUCH brighter when I put my finger on the slider, even though the slider is all the way to the right...? Just to clarify - the slider is all the way to the right, but when I put my finger on it, the brightness bulb lights up and the screen is much brighter, but I can't get it to stay that way. As soon as I lift my finger off, the screen dims again. I have tried this with auto brightness ON and OFF, but generally I leave it off. Any tips on how to get the MAX brightness possible from the iPad air? Thanks!
