Cannot move to Micro SD

[Pieter15]

I put a micro SD card into my phone a while back and everything was working fine.
But a since couple of weeks I am no longer able to move anything to my SD. I am still able to read stuff from it like photos and music but I cannot write to it.
I tried using a different SD card but it still doesnt work

can you recall what you might have done recently before the problem started? (installed an app maybe?)

try to reformat your sd card again ( in device or via computer) make sure it has fat32 file system

if still not working try to software repair using Xperia Companion
