C'è nessuno che sa creare kernel che può testare quello che dice??Regarding vibration, this needs to be tested by someone who has the phone and knows how to build the kernel and make a boot image.
The driver for the vibrator is located here: https://github.com/arco/samsung-kern.../misc/vibetonz
The file of special interest is tspdrv.c where's there's some values that can be changed. I'm particularly thinking of the following:
#define VIBRATOR_PERIOD 87084/2
#define VIBRATOR_DUTY 87000/2
But it might also be some other values there than these that affects the vibration.
Btw, to build the kernel from my sources with the correct config for ICS, use ariesve_defconfig.
