I have a Sony Xperia z2, and I think since the lollipop update I am unable to either move files from my internal storage to sd card or even download them directly to my SD card. Please help me solve this issue. whenever I try to move a file from the internal storage to sd card it would say sth related to a software issue. Please bear in mind I m not talking about moving apps, only files like images, videos, songs etc. Please help me out. Thank you.
