Hi Jack, I tried your suggestion but the touch screen is still acting 90 degree shifted. the main lock screen should open by a horizontal swipe but it opens with a vertical swipe (and hence everything else after that is 90 deg shifted)
The s3c_ts.c (samsung SMDK6410) file which i am using for touchscreen had this as original settings: input_set_abs_params(ts->dev, ABS_X, 0,800, 0, 0); input_set_abs_params(ts->dev, ABS_Y, 0,480, 0, 0); I tried a few changes like ABS_X=240, ABS_Y=320 result:-touch sensitive area decreased to the top 25% of the screen, still 90deg shifted ABS_X=480, ABS_Y=640 result:-touch sensitive area decreased to the top 50% of the screen, still 90deg shifted ABS_X=600, ABS_Y=640 result:-touch sensitive area decreased to right of screen, still 90deg shifted ABS_X=480, ABS_Y=800 result:-touch sensitive area decreased to the left 50% of the screen, still 90deg shifted in all these the 90 deg shift is still there. can u pls suggest anything else i can try.
