I use two pens, but they do not work well.
Make sure that there is enough space between the two pens at multi-touching.
There is a screen touch malfunction such as slow or
inaccurate responding.
Make sure that there are no foreign substances on the screen surface.
Check whether the screen is broken.
Make sure that the product is not exposed to direct sunlight.
When the product is turned on after turning off, do not tap the screen because touch
calibration is performed for 5 seconds.
