Mine has froze twice on me now. Few days ago (after I paid to remove ads) I opened my KFHD cover and it was stuck on a screensaver, I opened and closed the cover again and again. Touched with finger and nothing. So I had to hard reset and it took many tries to finally get it going again.
The first time I think it froze up because I kept hitting page turns and it wasn't responding. Think they may need an update
