Add independend angle level calibration for landscape and portrate modes.

[Michael Skolsky]

Is it possible to add independend angle level calibration for landscape and portrait modes?
It looks like accelerometer in my tablet (Lenovo TB-8704X, Android 8.1.0) gives some systematic error.
After angle calibration in the landscape mode portrait photos are non vertical and vice versa.
At the example angle is calibrated for landscape mode.
