I am using a 7" LCD (800*480)display(RGB interface) with cap touch (I2C interface) and the touch controller used is HY4635 and IMX6 SOLO processor is used. So the response of the touch is not very accurate and when the values are read in terminal window most of the time it shows wrong (X,Y) values like out of bound.
Only some times there is the response . we cannot do the drag operation but once in a while just single touch will respond that to very slowly .
Can anyone please suggest whats the issue?
Any driver changes that need to be done ?
