3:Ater that close the Gimabal Para Settings screen at ones when the calibration begin.
With that X mark on top right corner.
When i let the Gimbal Para Settings screen open till the calibration was ready
i always get an Tilt horizon.
When i close the screen fast, its always fine i tested this allot of times and it seem to work for me
