thank you. for your reply.:good: Affirmative. The app you named says "gyroscope" from "STMicroelectronics". The graph promptly responds to movements.
EDIT: It seems like it's a fake/software gyroscope, derived from data obtained by the accelerometer and directional sensors. At least this is how it was with the P8 Lite from 2015, and I'd bet from the technical sheets around it's the same on the new model.
I tested the gyroscope on a P8 Lite 2017 with a YouTube 360° video and it works awfully on the X axis, making the video very jerky and almost not moving at all, while it works fine on the Y axis. Maybe the software solution is not complete, maybe it's a bug that will hopefully get sorted out.
