Think I might have stumbled upon a solution of sorts: I had problems connecting my Gear 360 camera with the Gear 360 (New) app on my Samsung S6. No help from tech support, as usual. So, after bumbling around, I thought I'd

1. Uninstall Samsung Accessory Service (in the app manager).

2. I also uninstalled the Gear 360 app.

3. Unpaired the Gear 360 camera on Bluetooth.

4. Re-started everything.

5. Re-installed just the Gear 360 app on my phone.

6. Attempted to re-connect the Gear 360 camera from within the app.

7. I believe this would trigger the app to automatically install the proper Samsung Accessory Service app.

8. The app started to connect properly to the camera.

Now, the app still isn't impressive but at least that got the camera to connect to the phone app.

Good luck.
