Hi, I am new to Xiaomi and I do not know where to post a request so devs can see it and try to fix it. It seems that MI2S touchscreen has some accuracy problems when a handwriting note taking app is used. It is not able to drwa circular and diagonal lines with accuracy. Since its screen is great in accuracy and responsiveness, could it be "just" a driver issue? For additional help, I kindly point you to a related thread.
