Why 360 photo in Google Street View is supported only in phones with gyroscope? I got few phone but all without gyroscope. In all of them, Street View app says:


  360 photo capture is not supported on this device.


Why gyroscope is a must, are the gravity &amp; compass not reliable to make 360 pictures?

Update:

Both gravity &amp; compass have (x,y,z) components and I know both have some drawbacks:


gravity sensor is affected by acceleration (motion).
compass sensor is affected by metals and sometimes get locked is a direction. (move device in 8 path to free it).


Also:


gyroscope has little drift with time (may not affect in this case)


Anyway, are these enough reasons to drop phones without gyro from 360 photo capturing?
Basically 360 photo is a set of photos on a large canvas. gyroscope tells us the orientation of phone. inside the 360 photo viewer module the orientation is mapped to that large canvas with different photos. so when we look around. gyroscope tells operating system about the orientation of mobile and displays respective photo on screen.
