If this is very important for you you can change it using Calibre or Sigil.
I do have Calibre, but most of my pdf files are scanned (include lots of images and words, like the series of was ist was for children). So converting the pdf into epub does not really help.
But i wonder how some android apps solve this problem. I used to have "Mantano" app in my handy, and it worked far better than i imagined. The words in the scanned files looked broken and fragile, but through this "Mantano", they appear very clear to me.
Is there also such a software to improve the reading of scanned pdf in M92?
