so first of all, copying to my s4 with mtp is slower than copying to my s1 with ums.
whenever i try to copy a video file, windows always asks me if i really want to do that because my device won't be able to play it (wtf?)
and some other minor quirks but still, enough for me to want to go back to ums
So things I tried (of course my devide is rooted):
SGS3 easy UMS, didn't work
sadly, su, setprop persist.sys.usb.config mass_storage, reboot didnt work either
so any other ideas would be very helpful
