Guys, thank you for you replies and proposals.
Unfortunately, as my phone is running with Android 4.4 and blocked by Samsung to update to a more recent version, I cannot install and use Musicbee Wifi Sync as advised because it requires Android 5.0 minimum.
An alternative would be to use an apk of an older version of the app but I have not been able to found one. Do you have any advise?
I was under the impression preview and sync are working fine, it's just that the profile gets reset every time the phone connected to MB. My thought is that once the profile is created, if they don't have to plug the phone in again, it won't be an issue. Or at least less frequently.
Sorry, psychoadept, I don't understand what you mean!?
What is happening is that when I connect my phone for the first time, MB is creating automatically a device called GT-I9195. Then I configure the different options, and proceed a sync. Everything goes fine.
The problem is the next time, when I connect my phone, MB is creating a NEW device called GT-I9195 with by default options. So, I have to reconfigure all the options. If, I do that and proceed to a new sync then MB is not recognizing the previous sync and database on the phone and re-sync from scratch creating a huge mess on my music database on the phone.
I would add that MB is creating automatically a device whatever is plugged on usb port. So regularly, I have new devices created with the names of the usb keys I am using. Is there an option to avoid MB creating new devices automatically?
Thank you very much for your help!
