Sensor Calibration Auto rotation?

[Guest TitiD21]

Hello,

After a poor start, phone ended up in "factory mode" in the Korean language I guess.
After several manipulations to exit the "mode", phone restarts with "factory reset".
So reconfiguration and relocation program OK
By cons, management of self rotation is completely screwed up.
How can we re-calibrate the sensor and which sensor?

Thank you in advance
