iPhone 5s with LG bluetooth headset
I have 2 sets of LG headphones, 700 and 730. On IOS 7.0.2 the headset would play music, but the pause, skip fwd, and skip back did not work (beeped, but no other response). Though I did not see mention of this bug in the release notes, IOS 7.0.3 corrected the problem.
