Re: QC 35 II connecting issues
@MatteoB729Your latest reponse indicates it may have something to do with your S9. Now try it on another S9. If it is the same problem - it is a generic issue. If not, it is something specific to your particular S9. In the first case, it may have something to do with the version of your Android operating system or it could be an outstanding incompatibility which could reside in either the S9 firmware, the Android operating system code, or the QC35ii firmware and the way it interacts with an S9. In the second case, you may be able to update something on your S9 to make the issue go away.
Check out the other posts here again as over the last few months I have seen other S9 users having issues with the QC35ii. The frustrating thing will be unfortunately, if you can't update or change something on your phone, you will need to depend on one or more of Samsung, Google and/or Bose to make changes to their stuff and in the best of situations that could be slow to materialize.
