Hello, dear friends.

The reaction of touch is bad recently. I feel that reaction got worse when I applied the liquid crystal protective sheet. I feel that the position of the finger and the position where the touch is reacting are misaligned.
In such a case please check the state of multi touch with this application.
You can test how many points you react with the touch position.

If you react slowly when you touch it, you may have to fix it by trying a smartphone restart or memory cleaner etc, so please try it before repairing it.

By the way, when trying with a few terminals, it seems that most terminals will react up to 5 fingers.
