Tell me, is it even possible in principle to determine the yaw angle of the device (yaw, rotation about the vertical axis) using only the accelerometer. How to do this using a magnetometer (compass) is clear to me.
- To do this, you must be sure that the device has two accelerometers in the xy - rjhdby reference plane

With one accelerometer in the desired plane (xy), this can be done only if you absolutely know exactly which point the device is rotating around. If the axis of rotation is unknown, then additional data sources, such as a gyroscope, will be needed.
Here is an article on how to determine angles using an accelerometer and a gyroscope.
UPD For Roll and Pitch, in principle, for a device resting or evenly moving, it is possible to build on the acceleration of gravity. For Yaw, this trick will not work.
