I'm actually having the exact problems you all are having with the pitch sensor, ever since I moved to DK28. Right now it is annoying, but I am hoping it will be resolved when DL11 is released. If not, it looks like I'll have to call Sprint and have them get me a new phone, because some programs don't work correctly right now.

I noticed this problem while using maps, my compass seemed to have East and West swapped (but North and South were fine). I used the calibration tool in the Settings menu under "Display" (horizontal calibration), but I put the phone on the table upside down (hanging off the edge enough for the "calibrate" button to be in reach).

Not ony did this fix my compass, it seems to have improved the auto rotation response time dramatically

Wow...that seemed to help a ton. The games are off, but I don't really play them anymore so no issue. Sky map actually works now. The auto rotation is much better also. Thanks.

Edit: This fix works. I also started my game prior to doing the fix paused it and did the calibration. The game works great now.

Thanks! This seems to have fixed problem. I'm not exactly sure which part fixed it for me so I'll just go through what I did. I placed my phone face down and did the calibration in display settings, but then my phone wasn't switching to the correct orientation, so I rebooted my phone to see if that would help. It didn't. So I then did the terminal emulator calibration and now it's fixed. So, that makes me wonder if it has something to do with the calibration utility in display settings having some settings that are flipped around.

Woah... that worked. For whatever reason, it actually worked. Hmm...

Wow!

I actually tried the upside down trick once before with out success. Thought I had some results this time... then added another step. Voilla!

1. Working on a rooted froyo ROM. Upside down horizontal calibration from system/display/settings/display.

2. Reboot. (Not sure if that step is needed)

3. Connectbot su system/bin/sensorcalibutil_yamaha

At this point, sensor debug showed no success. Pitch and roll both limited to 30 deg.

4. Settings/display/autorotate. Uncheck.

Back in sensor debug, every thing checked out.

Anyone think it's still fixed if you enable autorotate?

I agree that the calibration in display settings seems to be the problem, sensorcalibutil works fine right-side-up. But sensorcalibutil didn't seem to fix the orientation lag, so it's possible that the display settings' calibration is correct, the internal compass I installed upside down, and sensorcalibutil has been modified to compensate... but I doubt it, the hardware should work no matter what the orientation, so a software problem in the settings' calibration is more likely the cause

I've tried everything in this thread and I still can't get google sky maps to tilt up, above the horizon. Anyone word on EB13 resolving this particular issue?

no matter what i do, pitch is never a positive value in sensordebug..

THANK YOUUUUUUUUUUUUU!!!!!!!!!!!!!

I was just about to return my phone for a replacement because I thought my compass hardware was broken, but no, I only needed to recalibrate my horizontal sensor upside down! Thank you SO much. You, sir, are a genius!
