Hi, I have exchanged my brand new iPhone 6s Plus 3 times in a row. 1st was damaged Display with some dead or stuck pixel. the 2 other I exchanged had the following weird phenomenon. If you hold the phone between your fingers like a sandwich near the mute switch and volume buttons und you push a little bit harder it comes a lot of air (burst) out of it (between display and rear shell) and a chemical smell like glue. It also makes the noice like from a Perfume Bottle. (NO JOKE) Does someone else have this issue. My iPhone 6 Plus didn't have this issue. Gonna exchange it again. All devices were C39 which unfortunately had the Samsung Chip in it.
