I just finished setting up a galaxy s7 edge. I connected the phone to my computer (Windows 7) using the charger cable. Attempting to transfer files crashes explorer. Sometimes I can't even see the folders in the phone, sometimes I can. I did manage to transfer a small file once (211kb). Usually the green bar on the address bar just loads for a very long time before crashing explorer. Also I can't use explorer during this. I pulled down the notification bar and selected the USB media transfer option, it said MTP. I tried all the other options as well. On my old phone (galaxy s5) I was able to simply drag and drop files to transfer. Is that no longer the case? Or is my phone defective? Does windows 7 not support MTP file transfers? Any help would be appreciated.
