iPhone 5s accelerometer/gyroscope/compass values incorrect

Do you know why the other thread got closed?

 

So people should just keep this problem to themselves since the other thread closed down?

 

lol no I was actually curious why it closed because I contributed to that thread.

The other thread was shut down because of a certain user or 2 that was derailing it. This is a clear problem affects gameplay for games and apps that use the accelerometer. Xplane for instance the plane drifts to the right big time on my device. Plus or minus 1 is of for allowable tolerances but not 4, 5, or 6 many of us are getting. Don't let someone tell you its OCD and is acceptable its not at least for people who use this function.

 

iPhone 5S Gyro issues

I posted this in another thread and a mod immediately closed the thread for some reason unknown to me. Is anyone else's gyro not working correctly on their 5S?



Left iPhone 5S
Middle iPhone 5
Right iPhone 5

Also, this is really weird... None of the compasses are reporting the same direction.



Anyone else experiencing this?

 

As far the compasses all different, are they all set to true north or magnetic?

Mine 5S is off only 0.4*…….

 

I have no idea honestly, where is that setting and what is the difference haha

 

The compass is off on all phones because you have them all together. The magnetic field from the electronic components will throw it off.

 

5S accelerometer is messed up

Mine is 4 degrees off on the tilt function and the compass is also slightly off. Anyone else having this problem?

 

How do you know its 4°?

 

Yep. Just got mine today and same deal with the orientation. I have to lift the corner for it to zero out. This is on a known level surface.

 

Yep. 5S on left, other two are iphone 5

 

Yup, it must be because mine is of only 0.4*…….

 

The 5S might actually be more accurate due to the M7, which means the iPhone 5 devices could possibly be showing an incorrect reading. Just a thought.

 

I can just visually see that mine is also in error. I guess if could give some numbers to back that up if needed. My 4s was very accurate. This level seems sloppy and loose. It does make me wonder two things:

1. Since the new M7 motion chip has a lot to do with running numbers for rhe gyro, might bad data in from a gyro that's off by significant amounts result in bad numbers on the output side?

2. Is this a software issue and easily fixable, or is this a hardware issue that might not be so easily fixed?

Update: I leveled it against a Stabila smart level. Seems it's off by 4 degrees. That's unacceptable and a significant amount- especially in light of this phone being touted as such a motion device.

 

Would be more valid if there were a leveled level tool in the frame too!

 

Because when I place it on a flat surface it's always 4 degrees off

My 4S with ios7 was accurate

 

Are you also seeing a jittery/jump effect when you unlock the phone? As per this thread - http://forums.macrumors.com/showthread.php?t=1643977

Could be a software/hardware issue with the motion sensors.

I'm also seeing the same thing as you with the gyro being a bit off.

 

Yes, as mentioned in my thread it's about 4 degrees off level

I wonder why that other thread got closed. It seems that this is a widespread issue

 

Dunno why it was so suddenly closed. Apparently It went "off the tracks" so let's try to keep this thread on the tracks!

I went to apple.com/feedback and submitted it as a bug item. Maybe if others do likewise we can spur a fix for it!

 

-3 here :S
