Have you tried card in another device or reader? Sometimes cards go read only before it brakes completely.

Yes. I tried. I checked the card and it's ok and totally writable

That's interesting ... There are 2 ways to do that : 1) is root u're device ( if u have twrp is pretty easy to do that ) and install a terminal ( let's say termux from play store ) run termux with these commands : tsu ( wich will prompt u to grant root access )
Mount system RW: mount -o rw,remount,rw /path-to-your-sdcard ( this is for read and write )
Mount system RO: mount -o ro,remount,rw /path-to-sdcard ( and this is for putting back read only )
But u have to do that after every restart/reboot/boot

And 2) way it's even easyer : after you root u're device go to google play and install sdcard fix, run it and enable it root rights ( it will ask for root just agree to that ).

How to root with twrp: TWRP menu, choose Advanced/SuperSU and follow the easy instructions.
But we need to see what version are u running on u're phone first, Miui v ? Beta - Stable? Go to setting - about the phone and make a screen shot ( print screen - both at the same time : power + volume down ) and uploaded so we can see..
