What do you use to edit PDF on your phone? - Lemmy

Dear Lemmings, I deal with several PDF files on a daily basis. I’m still struggling to find a nice FOSS app to edit my PDFs on my phone. My common needs are : - OCR the content - merge pages - delete pages - reorder pages A bonus would be: - edit content - fill form, print / send to email Do you know one which is able to do this? Many thanks
