I have only had the phone for a couple of days and I am noticing a strange issue. When I try to move files on the phone to the SD card, it fails every time. I try using various file management programs to move files and delete files within certain applications and it fails every time. I have searched and a lot of people are saying this is a Kit Kat limitation but I had no issues with my Samsung Galaxy Note 3. I have a 32GB SD card in the device and my device is not rooted.
