My iPhone 6 Plus which has 8.1.1 seems to be having issues intermittently with my Bluetooth speaker, which is a Bose Soundlink 3 speaker. I have made sure the speaker has the latest firmware, and I even done a factory reset setting on my phone. My issue I am having is that I will be listening music and it will just drop the volume in half at random times. Sometimes if I don't do anything for a couple of minutes, it will go back to the volume it was originally at. Any feedback would be much appreciated, especially if you have had the same issues and you found a resolution. Thanks!!
