Hmm, A kernel rebuild?
huawei_s7_kernel / drivers / input / mouse / msm_touchpad.c
#define TOUCHPAD_MAX_TAP_DIAMETER 100
#define TOUCHPAD_TOUCH_COUNT 16
#define TOUCHPAD_NO_TOUCH_COUNT 38
#define TOUCHPAD_Z_IDLE_COUNT (TOUCHPAD_NO_TOUCH_COUNT + 5)
#define TOUCHPAD_CALIBRATION_TIMEOUT (msecs_to_jiffies(200))
#define TOUCHPAD_BUF_SIZE 4
I think the touchscreen is here:
/ drivers / input / touchscreen / msm_touch-s70.c
Won't know until i get off work in 4 hours and rebuild back home later...
