Just went from HTC EVO 4G to Droid DNA. Been loving the speed, the sharp screen, and lack of dropped calls (Sprint to Verizon.) Only one issue thus far (besides the plastic charge port tab that I simply ripped off,) is I quite happily used SyncToy 2.1 to run files from PC to EVO or vice versa. Problem is on DNA, the Ok button is greyed out when I'm on the desired folder. Already saw the SyncToy and MicroSD thread. On my DNA Settings >Wireless and Network>USB Utilities>, the USB mass storage is greyed out. Anybody have a clue? I really like ST as I can copy source to target folder, rather than auto sync. And I can use USB cable, rather than fool with the cloud.
