The tablet supports connecting to a computer and an Android device, and the two modes are used in different ways.
The factory default is the computer model. If you encounter the situation of "drawing a vertical line horizontally" or "drawing a circle to become an ellipse" during use, it means that it is currently in another mode of use. You can switch between the two usage modes using.

❄Please press and hold the upper and lower buttons of the scroll wheel on the tablet for more than 5 seconds at the same time to release your hand (if there is no scroll wheel, please choose any two buttons), and if you see the indicator light flashing quickly for a few times when you release your hand, it means the coordinate mode switch successfully.
(Please note: You can use this method to solve every time you encounter a problem with the line drawing direction)
