Handsfree works fine for me. Perhaps a different set of headphones/switch? (UK phone, end of Sep. with v.I4 firmware)
Scenario 1)
- Music playing (single album, normal, not shuffle)
- Phone rings.
- Hit silver button on cord which stops music and answers phone.
- When call ends, do not mess with button. ( If the other person does not hang up, there could be a problem, but that's very rare. )
- Call ends on remote disconnect.
- Music automatically resumes.
- Buttons still work as normal.
Scenario 2)
Music, ring, button, chat...
At this point, if you hit that sliver button one or more times and attempt to end the call, you may end up sending signals to music player, such as 'set the player to party shuffle and go to next track'. Buttons work well after that, but at that point its too annoying, so you'll probably just pull over, change back to album, single and carry on.
But at least you stayed legal and the buttons work as expected.
Anyone else?
