Touchpanel made of glass. I have broke it once. So its probably glass protection foil.Got a Note 10.1 8010 on a fleamarket, just to check what's possible with it today. By now, it has replaced an Lenovo with no AOSP support anymore. It's a great work, many thanks for it. Until now, it works fine without reboots.
The only disadvantage is, that the screen seems to have a screen protection foil on it (with some bubbles), but i cannot peel it off. Or is the touchpanel made of plastic?
