Lined up against my apple box separating my iphone 4 and iphone 5s pointing directly south, here are the readings. I did this because the stainless steel band and/or other parts of the 4 were affecting the compass when lined up against each other. I might go over to a buddies and use his iphone 5 to take pics or video. Lets keep this thread civil and on track. Please present facts only. Trolls need not reply... There are now quite a few article's about this issue: http://www.cultofmac.com/247282/iphone-5s-compass-off-base/ http://gizmodo.com/the-iphone-5s-motion-sensors-are-totally-screwed-up-1440286727 http://www.macrumors.com/2013/10/03/calibration-on-iphone-5s-compass-and-level-appears-incorrect/ http://9to5mac.com/2013/10/03/iphone-5s-sensors-providing-inaccurate-readings-for-some/ http://venturebeat.com/2013/10/03/a...ed-up-and-so-are-the-games-that-rely-on-them/ http://news.cnet.com/8301-13579_3-5...-motion-sensor-malfunction-may-be-widespread/ http://www.forbes.com/sites/tonybradley/2013/10/04/apple-iphone-5s-sensors-are-jacked/ Both Compass's set to magnetic north: iphone 5s reads: 165s iphone 4 reads: 179s <--- Reads correctly compared to the compass in my cessna Swipe from right to left to get Apples level app: iphone 5s reads: -4 degrees iphone 4 via iHandy level reads: 0 degrees level 2 different Johnson levels used as well. 24" and 48". I had to raise the level until the bubble bottomed out in the glass to make the iphone 5s read zero. Have you tested this? I have contacted apple support and they suggested replacing the phone. At this point, I'm going to wait it out as I can live with this defect until I know the problem has been fixed. I spent 34.99 oh a front and rear film protector that I will have to eat when/if the device gets replaced. OCD does not alloy me to use any device naked. What are your results? good or bad... If yours it out of spec. I suggest reporting this to apple directly to get this problem resolved quicker. They said that they are monitoring feedback in real-time, at this time www.apple.com/feedback Ok so that calibration procedure had no effect on the invalid data from the senors. 7.0.2 update had no positive effect as well. Sensor-Gate is still lurking... 7.0.3 seems to have corrected the problem for a lot of people.
