Ive noticed that the screen on the iPad Air 2 is very dim when compared with the other iPhones and iPads that I have. Even at max brightness, it appears rather dim. I usually always use auto brightness on my iPhone 6+, but it is just way too dim on the iPad Air 2. Also, I know we used to be able to set the auto brightness levels by adjusting the brightness level in a dark room with auto brightness off, and then turning it on and going into a brighter room. This doesn't work now. I try that, but then I turn auto brightness on, it just goes back to "auto" mode not remembering what my preferred low level is. Help!!
