about lcd umi plus

epilog

Hi, I am from Indonesia
I accidentally dropped umi plus to an asphalt road
glass cracked due to hit the small stone, and crack extends to the other side
touch buttons are still working in some areas, but in the area of the crack does not work

I want to ask,
1. do I just need to replace just the LCD glass
2. or all of that glass LCD and touchscreen panel

and please recommend an online store that's providing the spare parts
Thank you for your attention

epilog

the problem is finished
I ordered 1 package of touch screen and lcd
duration of approximately 12 days delivery
and now, my UMI already using the new touch screen
function well as a new purchase
