Smart Connect doesn't recognize bluetooth connection anymore

[Vins282828]

With SmartConnect, I used to turn on music and mobile data when my bluetooth car device pair my phone.

Working well until last the last Android Update (I think...).

But now, Smart Connect doesn't recognize ANY bluetooth connection (tried with headset or earphone recently).

I have to switch manually the event myself and so SmartConnect see that the bluetooth device is connected and then launch all the actions I want.

What I have:

Sony Xperia Z3 Compact (D5803)
Android 5.1.1
Build 23.4.A.1.232

Already tried to uninstall SmartConnect updates, no effects.

Thanks !

2. Find and tap Settings > Apps.
3. Swipe to the All tab.
4. Find and tap on the app.
5. Tap Force stop > Clear data.
6. Restart the phone

Does it work while on safe mode?

If that doesn't work then repair the phone with Sony PC Companion.
