If the device supports pan-tilt-zoom(PTZ) function, the reasons for rotation are as follows:
Automatic rotation function: Your device may have the automatic rotation function enabled for motion tracking. When you change the orientation of the device, the screen will automatically rotate to adapt to the new direction.
Sensor malfunction: The accelerometer or gyroscope on the device may be faulty, causing it to mistakenly detect continuous rotation. You can try restarting the device or performing a software update to fix the sensor issue.
Improper handling: Sometimes, accidental finger touches or improper device holding positions may cause the screen to rotate. Try to avoid touching the edges of the screen with your fingers and keep the device in a stable position to reduce the occurrence of accidental screen rotation.
Device reboot: The device may undergo a self-check process and rotate during startup after a restart, power outage, or network disconnection.
By checking the possible reasons above and taking appropriate actions, you should be able to resolve the issue of frequent screen rotation.
