Good evening. I said bottom button (near the USB socket) ....
I looked at the forum and saw that some thought that the collections of over 100 ebooks make problems. I had collections > 200. I've upgraded my collections (on my computer, in Calibre) for going under 100. Currently, on the K5, I have created 15 collections. 1 is empty. Many many books are out of collections. I find the crash log:
