Also, Spotify app was reported to capture connections and even reconnect to devices. Don't know if it still does it and if it's related.

Hi, we don't do any magic in nRF Connect. The same method is used. Make sure you don't have nRF Connect (or any other app) with GATT server configured and not disabled running in background when you connect/disconnect from your app. Then the nRF Connect could just connect to it as well and your disconnect won't actually disconnect the physical connection as it is still being used by the nRF app. Just close the nRF Connect with the Back button instead of Home to make sure it's properly closed.

When you disconnect, remember to call gatt.close() when you get the onConnectionStateChanged(state: disconnected).

Also, I highly recommend using the BleManager class from nRF Toolbox. Or at least checking it. github.com/.../BleManager.java
