[Android][Bluetooth] Metadata is not transmitted

[faberdb]

Hello, 

When, a couple of months ago, I connected my Samsung S7 (no brand and always updated) in my BMW X3 over the Bluetooth connection,  I thought I dreamt since I saw, for a few seconds, track and title appearing on the display of the car. After a stop and start, on the way, such metadata where not displayed anymore... 

And this happened until yesterday when, suddenly, title and track appeared once again! And I took a snapshot of that, this time! Another stop with my cr, restart and... once again no metadata once again! 

Where's the problem?!

Thanks in advance!
