I use a Sony 64GB mSD (rebadged Samsung) on my Glo HD and it actually felt faster after mSD replacement.
Interesting. I did a benchmark of the Sandisk Edge (Crystaldisk) that came with the Clara HD and it has a random 4K write of 0.5MB/s, which in theory, going back to the home screen should feel slower when it is faster.

Perhaps you have too many books, a large base.

Or in vain did you change the sd card by choosing such a sd card, because of which everything began to work slowly.
I only have ~500 books on the device, though some books are around the 100MB mark.

I checked the database size and it's at 110MB.

I reckon so as well. Unfortunately, I don't have Samsung cards where I'm from and ordering them online plus taxes comes to twice the price of the product. My options were the Toshiba or a Lexar which was even slower (class 4).

The interesting bit is though that the device feels faster, navigating and opening books are snappier as well. It's just the going back to the home screen from a book the issue.

Do you guys reckon it's a cover image issue? Is it redrawing all the covers in the background when I switch to the home screen?
