Until two weeks ago, I could pair my S4 with car audio via bluetooth and listen to music, and use the Track UP/DOWN buttons, volume UP/Down control etc in my car steering column. But after the recent update by Samsung, the car volume UP/DOWN works, but not the track changer!!
The same music album, in another phone works well with the car audio with all functions. So it is not the car problem but the Samsung S4 update problem
Has anyone experienced the same problem?
is there any solution?
Samsung people are of no use at all when it comes to these issues.
