This is a bug that has existed for a long time and was confirmed after I recently replaced the USB Hub with a new one. Turning the viewpoint during walking or sprinting while the phone is connected to a keyboard and mouse produces a screen jerk, which I used to think was due to a lack of power supply, but it's still there after I've accessed additional power, which I think is a bug because if you jump a bit while moving, the screen jerk goes away. But you know, needing to jump every time you walk to fix the screen jerk isn't a convenient way to do it, hopefully you guys can fix this soon. Thanks.
