I'm posting this here as I've been unable to get any advice from Kobo.help or the regular Mobilereads Kobo forum. Hopefully someone here may have a solution for this problem

My Kobo Touch (2 years old - N905B) has recently started to freeze while I read. After a few minutes, it responds to the string of instructions that I had given it while it was frozen and then functions properly until the next freeze. I believe this only started after my recent upgrade to firmware 3.8

I guess it can be better described as "slow processing", makes me feel that the problem has to do with memory buffering (but I'm no software expert).

I've tried:
logging out/in,
Pin hole reset,
Factory reset (several times)
Deleting all my books, except one new one, to see if the problem is being created by a corrupt file
Downloading a new book to see if the problem occurred there (it did)

To my surprise I found that increasing the size of my font stopped the problem for a few days - but then it started again

FYI my wife's Kobo Touch (same vintage and same books as mine) doesn't have this freezing problem, but I've read (on Mobilereads Kobo forum) that some other readers are having this problem.

Does this sound like a problem with the SD card? I would appreciate any ideas as this is getting very frustrating.

Thank you
