Seems like this may have sorted itself out.......I'm thinking it may only be an issue whenever I update MM on the PC and/or my phone. FYI......wireless synch is taking forever now. I recall having this issue before and asking about it. I tried searching for it but can't seem to find the answer/fix. Do you recall that?

Updating shouldn't be an issue as the device has a device ID stored (in the MMA folder).

Will do! Does the PC look at devices as "new" devices when the MM device software is updated?

Send a debug log from MMA (from About screen) after sync.

4.1.3.1708 and 1.0.6.0285

Which exact version of MMA and MMW?

I've noticed recently (last two releases) when I synch my Galaxy S5 my PC is recognizing the phone as a "new" device and adds it to the list of devices. This causes me to have to go in and recheck all the music I want synched on the "correct" S5 internal/external storage places listed in the Available Devices window. Is this a bug or am I missing a checkbox somewhere?
