Hey guys, I bought my iPad Air last monday, and as it is my first iPad I have some doubts concerning the buttons. So I've used my iPad within a case from Monday to Friday, but as the case was really bad overall I decided to trade it back. However, as I started using the iPad without the case, noticed that the my lock button and volume up (mainly) are a bit loose. Nothing to really worry about, however it is noticeably enough so that if I flick my finger over the volume up, it makes a distinct sound. The lock button, isn't as bad, but is noticeable enough for it to sway a little from left to right. So now I'm facing a though decision: Should I try to trade it or should I keep it as my screen is really good and I've read some reports of strange yellow and greenish tints in some units. What should I do? Is it normal on the iPads? I'm only worried about it because I've had some problems in the past with my lock button popping off on my iPhone 3 from extended usage.
