The touch screen is unresponsive

i think the problem is sometimes it gets wet on my bag.. but its not too much..

i dont usually turn it off. i just used the sleep/wake button..

well, before, its touch screen becomes unresponsive already and all i have to do is press the sleep/wake button and suddenly its ok.. but the last time i put it out of my bag . the touch screen now is unresponsive ..

i have tried the reset.. and unluckily, refreshing on the itunes didnt work on my desktop, .. i tried to diagnose it and the error is 0xFFFFFFFF - i dont know what it means.. right now im trying the rice thing but its been a week.. it still stuck. :(

i hope.. repair would help.. or little cleaning ? does it need change parts?

yes its ipod 6th gen.. hmmm i assume the water damage .. sometimes my tissue wipes spills on my bag.. although i have the ipod on a pouch..

regarding the diagnosis.. i just press the sleep/wake button, volume up and down together , i just read the instruction on some forums over the internet..
