Facebook File Download Problem


Sep 5, 2020
Hello. Can anybody help me?

For example I'm trying to download xyz.pdf from a Facebook group.

Everything works when I do it on my PC,

but on my Xiaomi Redmi Note 8, in the Downloads it's shown as xyz.pdf, but its file type isn't recognised (Question mark icon). Like that:

I can open this file with PDF apps. when I share it via WhatsApp, Gmail etc. the file is called downloadfile-xx.bin. After I rename it to xyz.pdf, it works.

Files downloaded via Chrome are saved correctly.
I copied the download link on my phone, and opened it on my PC and it correctly downloads it as xyz.pdf.

Why does this happen?
