Not sure if this has been mentioned but using WiFi transfer (or pro as I use it on all my android devices I decided to pay for it) is a great way to move watch faces, music or whatever else you want to move from one device to another. It works really well with the D5
Helps if I leave a link
Airdroid. Is the best solution. And it’s completely free
I would recommend “Share it” application. Super easy and quick file / folder transfer via WiFi between PC or a phone. Round watch friendly. And also can recommend “Solid Explorer Classic” as your file manager. There is option to manage your cloud drives too. Round watch friendly as well.
The free version did everything I needed it to. I paid to support the developer. I’ll give these other ones a try though, thanks for the feedback
Other thing is you don’t need a client, which you appear to on airdroid as far as I can see. This means you can transfer files to and from any device on your network ( or hotspot) which I find really useful
That includes D5 to D5 if your Lucky enough to have 2!
