Help Gravity (or Magnetic) Sensor out of calibration

[armin3000]

When I hold my phone vertical (portrait or landscape) to take panorama or photosphere photos it's out of alignment and I have to downward it to the earth to adjust the horizon line to the middle of screen! In another word if I hold my phone in ~80° its sensor behave like it is in 90°. Attached photos shows the problem. I have rooted my device with official 4.4.2. I couldn't find any helpful guide about how to initialize or calibrate accelerometer or G-Sensor. rotating phone in 8 path, rotating around all 3 axises, restarting device didn't help.
Please help me how to solve this issue. I don't want to reset factory device right now. I've access to all system files if needed. Thanks

You can calibrate your orientation sensors.

Check out "Bubble"

Go to the menu, follow the prompts - hope this helps!

I had tested similar apps like bubble level, GPS Essential, GPS Status, Compass, .... I also tested this one now, No difference.

Your particular phone may have its sensor mounted at an angle to the chassis - slight manufacturing defect.

I'm probably wrong - but that's exactly what it sounds like - and if so, nothing you can do with sensors to correct it.

Or you're living in a house at a big angle from true, but I doubt that.

You mean it's a hardware problem?! It was working fid before but I don't know when it start doing like this! My device is rooted. Doesn't it help? I did a reset factory now but problem exists

Yeah - if you didn't drop or bang or sorta crush your phone to change the sensor positioning and it worked before then it's possible - but very likely NOT a hardware problem.

Rooting ought have nothing to do with it either.

What happens if you turn the phone 180°?

 

[armin3000]

As I remember it has fallen 2 times 1.5-2 feet! New photos are showing what is happening exactly. I also tested what you suggested.

I'm still not sure which physical sensor is causing such problem, Gravity, Accelerometer,etc.
