Mine is going back. The yellow tinge is severe on mine. These pics don't even begin to replicate the dirty white instead of bright white I see on my screen.
The picture above is of my new ipad mini 2 on the left, which i purchased release day and received today, and my ipad Air, both at 100% brightness. The Mini looks like it's been sitting in an airport smoke room for a year...
Not too mention, the new Mini's colors are nowhere near as vivid as the Air or previous Retina ipads.
Half-trillion $ company and their screen gets beat by Google and Amazon in color tests reported by the media. Disappointed.
