1. Has anyone bought an iPad Air 2 this year that was manufactured this year recently from factory, and if so does it still have the vibrating speaker issue like older models? @ Med to full volume where it shakes whole iPad? 2. Also does newly made iPad Air 2's have the problem still where you can see your fingers pressing or holding the backside through the screen making purple halo circles when holding tightly or with a firm grip? 3. Does iOS 9.3 run smoother on iPad Air 2 than previous versions, and how is battery life from full 2 day usage? (My iPad Air gets 13+ hours) Thank you! Wanted to get iPad Pro 2 but with 2gb ram and battery no bigger than air 2, it's going to drain the life out of its small battery with a display that always auto adjusts with multiple sensors and powerful cpu and gpu when utilized to the max.
