Hello,
Thanks for the elaborative answer. My comments:
1) It would be good to provide also another shortcut to 'de-compatible mode' then a series of steps. This compatibility mode and how to reverse it isn't described in the OCR manual
2) I am trying to OCR a children Chinese book with a printed characters, quite a medium size (not tiny or small sized). Focus has been used as well. What I notice is that the OCR when it seems to get it correctly, it kept on changing from recognising correct text (or most of it) to some random within the same second or two. It is quite hard to press pause when the time is right, since trying to reach pause button will cause the phone to move slightly and the recognition will change.
I will try OCR a still text but the live on is really useful.
Lastly, OCR would recognise some characters even though in that area just a empty white space.
PS: I'll try to take picture to illustrate my issue when I have a bit more time.
