5S Gyroscope/Accelerometer Error?

I have an iPhone 5S and iPhone 5 - both read the same level when placed on the same table; not one degree difference. I did read the Gizmodo 'sky is falling' article about it and they showed gross differences with their typical snarling & gnashing of teeth with regard to any Apple issue. It would be very easy to manufacture a bad reading and of course one needs to use the calibration feature however to quote Apple support site, "you shouldn't rely on it to determine precise locations, proximity, distance, or direction"

I'm an Apple fanboy and I am having the exact same problem that Gizmodo is reporting. Just because you dont have the problem does not mean it does not exist.

Make sure you are updated to 7.0.2 then charge the battery for atleast 90 minutes with the screen locked and do not disturb on.

I've updated my 5s to 7.0.2 but my gyroscope is still off by 3 degrees.

Hope they can get this fixed...

Apple's official response to this is to backup your device, erase/reset the phone and restore from the backup. Then turn on DoNotDisturb, plug the device into a charger, lock the screen and leave it completely still for a minimum of 90 minutes.

UPDATE: This fix had no effect. Apple have agreed there is a fault and are replacing my device.

I had this problem on my 5s 64G. Just received the replacement and it has the same problem. Sending that 1 back as well. Not a good sign. 2 phones, both faulty. I wonder how many of the new iPhones are faulty. People may not be checking for this fault, so are unaware. Has anyone here had a replacement that is good?

.. agreed, everyone should be checking for this fault. It's only covered for 12 months under Apple. I'll post back here again when I receive my replacement.

.. so I attended the Genius Bar at my local Apple Store to discuss this further and obtain a replacement iPhone. I was told that this hardware issue is 'across the board' and a replacement would simply reproduce the fault. I was assured that a system wide software update is coming to address the gyro/compass issues.

Some research online has also produced some interesting information, namely that Apple switched suppliers from STMicroelectronics to Bosch Sensortech in favour of a less power consuming component not realising that the new part had a bias of (-/+).95 microgravities (the STMicro component has a bias of (-/+) .20mg) and it's this that is causing iOS7 to falsely interpret the sensor data.

Crossing my fingers for a firmware fix or I fear that my 5s will be returned to Apple.

Fixed for me in 7.0.3 released today. Readings on my 5S agree with those on my iPhone 5.

For me 7.0.3 did not fix the problem. The readings are a bit better, but they still aren't 0 and don't match my iPhone 4S. One side actually got worse and went from 0 to 1. Currently I get -1 on the back (down from -3) and 1 to 2 on the sides.

7.0.3 didn't fix the issue with me either, Morac. Better, but not fixed.
