Font size and accessibility options on Onyx Boox device

[greg_1981]

Hi,

Due to (verry) poor vision, I am tempted to buy a large-format ereader. Probably an Onyx Boox Note Pro. But I'm wondering a few questions :

> Are Android accessibility options available ? Maybe they are hidden but can still be activated ?

> Is it possible to choose a default font size, or do you have to increase the font size each time you open a new file, which would be very constraining ?

> Is the range of font size increase limited, whether in Epub or PDF?

> Is it possible to make the background of the pages slightly grey?

Thanks for your help, and sorry for my bad english.
