connecting my bluetooth speaker to the Moto G it is not possible to control its volume (speaker is Philips SBT50). I can move the BT volume slider back and forth but the speaker volume doesn't change and it is much to loud.
I remember the same case using a Nexus 5 some time ago, but with the KitKat update to 4.4.2 the issue had gone. They described an issue with the bluetooth stack which caused that error. Perhaps the bugfix didn't find the way into the Motorola version of KitKat 4.4.2!?
For the Nexus 7 (2012) with KK 4.4.2 the bt volume control works great.
Is this a known issue for Motorola? Is there a bugfix/workaround available allready?
