Hi guys, I read through a lot of the forums here and on some other pages as well. Not that I am looking for any problems, but it's better to find out about any issues earlier than later. So one can check the phone right from the start. I did not really find any real issues so far. 1. Yellowing / Spots / Dust / Circles Few people seem to have a little problem with their displays (yellowing, dust spots/little spots). But only few people mentioned it and I guess that with over 4 million units there are always some which are not perfect. UPDATE: More spots and pictures of "circles": http://forums.macrumors.com/showthread.php?t=1783991 2. Wifi / You are holding it wrong One user (now one or two more) so far mentioned an issue with the wifi reception, when holding the iPhone in landscape mode. Anybody else has this issue?

Some users say, that they can press down the display at some parts (corners) and it moves a little bit up and down then. They already contacted Apple and will get an exchange. - People who read about it, tried it on their iPhone 5 / 5S and few found the same thing. Users on Macrumors mention the same thing: http://forums.macrumors.com/showthread.php?t=1783930 No issues yet: - Battery time: Of course some people complain about battery time, but the phones need some full charges and some time to adjust, before one can complain about it. - Box: Be careful when opening the box. Quite some people seem to drop the phone: http://forums.macrumors.com/showthread.php?t=1783949 - Heat: iPhone 6 heats up and is noticeably warm during heavy using. Few people here (see below) and in Germany mentioned this so far. Somebody mentioned as well the iPhone's 6 screen feeling quite hot. - Minor Scratch: In a German forum, few people report a minor scratch between display frame and body (higher resolution) Please keep in mind that a lot of the problems evolve from the "old" backup of your old phone. So if you have any issues you might want to try to reset your phone and give it a fresh start to make sure everything ist fine.
