iPad Air 2 pop noise video: Apple pls watch and fix
I was able to reproduce the noise twice in a minute. Battery fully charged. Will check later whether it does it with battery partially charged.
iPad Air 2 Wi-Fi, iOS 8.1
Apple does not participate here except in a very limited capacity and only to respond to users who have asked a question and not gotten any help at all after 24 hours. There have been a bunch of discussions about the iPad Air 2 and this popping noise problem. Search the community and look for one of those current discussions or make an appointment at an Apple Store and ask for their help.
Your iPad is still under warranty, so if you need to, return it and get one that works properly.
