I am having some bad software connectivity issues too after I installed and rebooted the mac with samsungdex. Now, the phone or mac does not think it can share files with each other, and the USB option to select file sharing, charging, MIDI, and etc does not appear on phone. The phone works with the same cable on another mac. But the mac with the samsungdex is now messed up for that usb connectivity with that phone, maybe all my android phones. I gotta test that. I removed the samsungdex from the mac and rebooted but the problem still persists. Bad, bad quality Samsung.
