I just installed the MINI App on a Samsung S6 Lite with the 1/24/2024 Android OS update, and I got the App to run OK, but with some difficulty because the Android OS is not responding “exactly” as before (as shown in the manual or on the web page).
First, I got my BT-210 paired OK (83 for me).
Next, I went to the MINI app SETTINGS, I got it set to SERVER:
Then I had difficulty to see the BT CONNECT screen as shown below (did you ever get to this step?)
I had to “BACKSPACE” several times out on the OS main tool bar in order to see the previous BT CONNECT screen.
Then if I tapped on my paired BT-210, I could see that the App is connecting to my BT-210, then I could see my RUN/EDIT screen
Then everything worked fine for me. So hopefully all this will help your progress.
