My iphone 6 when used in the bright Florida sun, dims it screen in one quick step. It goes down to what I estimate as about 85% of full brightness. Not a gradual decrease, just boom, 85%. The auto brightness is set to on and the slider scale shows full but the screen is much dimmer than full. I've gone in to the genius bar where they just replace the phone(3rd device). A few days ago with non-polarized sunglasses on, I saw the screen quickly go dim, then back to full several times. Re-booting brings the screen back to full but thats a pain.
Anybody here seen or heard of this?
I'm going to try with auto-brightness off today to try and reproduce it.
