Do any good file servers exist for Android that do not require root? Ideally, it'd be nice to just be able to have an SMB share, but the only app I was able to find for this (Samba Filesharing) requires root.
I'm currently using FTPDroid, but it's pretty slow (I'm getting about 200 KB/s downloads on my n600 wifi). Are there any better options?
I'm using a Verizon Galaxy S3.
