Resolve "Gimbal Lock" problem by using Quaternion for rotation

[craftercis]

I love this tool!

Just a quick question: In the first screenshot, that's how I want it to start when the user holds the phone vertically. Currently, it starts like in the second screenshot. When I place my mobile on a table, it looks like the first screenshot. Do you know how I can fix this?

If I have a Gyro rotator and a rotator attitude on this cube with a max offset of 30 on the Y. My phone starts at -30. I want this to be 0
