iPhone 5s accelerometer/gyroscope/compass values incorrect

The only reason I know about the issues are because I came here. If I hadn't seen this thread I wouldn't know there's a thing wrong with my phone because my battery life is great, nothing is crashing, my GPS works, messaging works, phone calls work, swiping works for incoming calls, multitasking works, and I can play word games and solitaire with no problems.
I never used the compass on my 4S and I had the phone for two years--I don't plan on using it with the 5S. I don't play games or use apps that rely on anything affected by the sensor issues. I'm guessing this is the case for most people and that's why it's not all over the national news.
Mine is -6 flat, -5 right side, +2 bottom edge

I guess if that represents the view of most then Apple are really wasting their time with the M7 features.
Irrespective of what people find acceptable a product should perform as advertise. Simples !
I completely agree with you! I was just giving my opinion on why I think we aren't seeing this all over big media outlets. Nothing more. I don't blame people one bit for being upset and wanting returns/refunds. I'll be taking mine back for a full refund if it turns out to be a hardware issue due to resale value at a later date. I still have 10 days to return the phone if the issue is not resolved.
I stated this elsewhere but the only reason I bought this phone knowing the existing issues is because my contract was up on the 4S. I wanted to give the 4S to my son and have it squared away before he's stationed overseas for three years--he'll be able to get a local carrier's SIM only plan without getting roped into a contract. I went ahead with the 5S purchase hoping it'll be a software fix.
So you have to hold your phone something like this for it to think it is level...
Have you tried making a panorama photo?
Yeah, that's correct. Well, to clarify, I need to do that when holding it landscape. In portrait, it works fine.
Can anyone help me In testing pano pictures that illustrate that the sensors are off? What should it be doing? Also does it only affect pano or normal pics too? Thanks
Mine is -3 on the right side and 1 on the left side. Next to my 5 which 0s out perfectly...
What is everyone doing with this? Returning? Waiting?
Edit: it seems to be affecting my panos, I have to almost point the phone downward

I returned my 5S to the Apple store yesterday. I'm going to hold out for 2-3 weeks and see what happens. I really hope this gets resolved in 7.0.3.
just out of curiosity, to the people who got service replacement as opposed to retail units, are the model numbers the same between old and new.
it seems that service units have different model numbers, I thought the serial numbers had a different prefix.

Same number, same factory. Looks like when they made my faulty one they just pulled some off the line and stuck it in a white box.
People, stop worrying about the white box units and ignore the scaremongers saying "omgodzzzz, they is made from old bits of dead chickens". White box units are the same, just without the bits and bobs.
There is at least one scenario by which this could be fixed by software, even a standard patch applied to all phones.
Apps (even Apples Compass app) do not make direct calls to the hardware, they get their data via the OS (e.g. the CMAttitude Class in the CoreMotion framework returns various numbers relating to the phones attitude). There are several reasons for this, but one is that the hardware itself in this instance needs calibration i.e. fine-tuning so that we know that a particular hardware reading equates to e.g. a perfectly horizontal phone. These calibration data are probably held in some non-volatile memory, and are set as the phones come through the production line, with each phone getting its own specific calibration data written into the NVRAM. The OS is then supposed to take the raw hardware reading, apply the calibration data from the NVRAM, and then give the calibrated reading to the app.
The problem we are seeing could be due to an iOS7 bug such that it either fails to apply the calibration data or it reads the wrong bit of the NVRAM so it applies an incorrect or zero calibration. If such a bug was fixed to make the OS apply the calibration data correctly, the results returned to the app would then be correctly calibrated again.
So all our phones may have the correct calibration data sitting on them but an iOS7 bug means these data are ignored and the OS is giving uncalibrated data. Because different phones have different calibration values, different phones show different incorrect values as a result of the bug. Occasionally, the raw values need only a very small or no correction, so these phones show the correct value.

Were all being delusional if we think 1) Apple is going to admit to this and 2) they will then issue a software fix, because without a global calibration in the settings menu a simple patch isn't going to work, and knowing apple after they just redesigned ios 7 they aren't going to do that. Lets come back to reality guys its just luck if you get a decent one or one that isn't horrible and you can live with. I will probably return my 5s and use my 5 sadly.
5s space grey 16gb here. Mine reads -3 on its back, -1 on each side
Went to the apple store for a genius appointment on thursday (Montreal). The genius seemed to be aware of the issue as he himself said he knew most of the 5s had this condition. He said they couldn't replace my phone as this was almost guaranteed this was software related and that a software update fixing this would surely come out soon..
He said he didnt know when the update would come out but that it should be fixed within one month.. He and another genius proposed to do the 90min do not disturb thing. I told them that i did do it and that it dit not improve at all.
The genius then admitted to previously exchanging other phones that had a similar issue but that were off to as much as -40 degrees!
So anyways I left, pretty annoyed that they couldn't do anything about that and headed downstairs to test the display phones. First of all we can see that they were all off at the exception of the only 4s on display. One of them was even -58 degrees off, straight out of calibration!
These pictures were taken with my 5s, and you can see how the gyroscope affects the orientation of the first two pictures. They were taken with the phone almost flat horizontal in the air, but still definitely in portrait mode instead of landscape. They display as landscape pictures.. The third pic was taken at an angle that was clearly landscape, so that one works..

I would be very surprised if Apple doesn't fix this via a software update. Apple fixes bugs all the time. I doubt they'll blatantly ignore this one.
No, a simple patch COULD work if it is an iOS bug that is incorrectly reading the calibration data (see my post above yours).
Otherwise, as you say, it would need a global calibration, which could be added in the settings menu. Why does the redesigned iOS mean they would not do that

Adding a calibration setting would require acknowledging there's a problem, which they have yet to do.
Even if it is added, I doubt we'd see it before iOS 7.1.
Reading the last 10 pages or so it seems like the problem is mostly on the C3 serial version while the D serial (foxconn) seems to be ok. Is this correct ?
Shit0la! I have a DPN space grey on the way week 39. Hopefully it will be perfect.
