I downloaded a pdf file from facebook group. but when i was to open the file i noticed that it is not typical red coloured icon pdf file. it's the same size of a regular pdf file but had a question mark icon. I tried to open but then my phone replies that type file isn't supported.
Please say how can i open that file.
NB.- I am a 'Redmi note 8 pro' user
