It's an interesting forum here. Got it by searching for answers for a special e-reader which someone brought to me to repair it (Kobo Glo HD).
I read books myself on a really old reader, a BeBook from 2009. Still happy with it. My wife uses a Sony reader for about ten years now.
Hope to find answers and to learn something here. Thanks!
Oh, English is not my first language, so sorry for mistakes maybe I make
