oi.. as title says - after opening the app on Vivo android with 8 GB RAM it shows folder menu.. when i tap on my books folder (600 epubs) it froze and then closes. When testing the menu - if i open it before taping on books folder - works..
there are no plugins installed, basically this is after fresh install.
I was really excited about using koreader, now in dispair.
Any idea what to do?

*EDIT* everything works except opening my books folder ...
