If the handle of the Boyueda S3-11 or Q7 Pro wobbles up and down, you can adjust the small screw inside the handle. Loosen the screw by turning it anti-clockwise, making small adjustments each time—approximately 90 degrees at a time—and adjust it gradually. Please note: you must loosen it by turning it anti-clockwise; do not tighten it.
Please refer to the video below for guidance on how to make the adjustments.
