How To Learn And Set The Left Touch Screen Button Function ?

Sometimes when touch screen can not work or can not work properly when you receive the head unit, pls do not worry, that is not quality problems, just do as below, then this issue can be solved :-)

Customer's problem:

Thanks for getting back to me, I did get everything working...

But I am having an issue, the buttons on the left are not responsive. The power, home, volume, gps and back buttons. I have to tap them like 10 times to work once. I bought the device off of amazon just a few days ago.

Let me know what I can do or try.

Thanks Mike
