I recently had to factory restore my M8 due to it constantly rebooting. After my factory restore, I can no longer move files (pictures and videos) to the external SD card. I had the ability to do that prior. I also lost the ability to transfer files from my internal SD to my computer. Can anyone help? . The transfers just hang and then fail. I am stock. No root. I should also note that I tried reformatting the SD card. I moved all the pictures and videos to the internal storage so I wouldn't lose them and could not move them back after reformatting.
Have you tried to move files to another computer?
Give more information. How are you trying to move files to your externalSD? Using your computer or using a file explorer.
You shouldn't be able to write files to your external Sd because of Kitkat's new permissions.
There is a workaround if you have root
