I couldn't find anything online regarding this issue so I was wondering if anyone else experienced it? When using a wired headset to listen to music or talk on the phone, if I jangle the chord near the bass the phone goes haywire. It dials the last call (or hangs up the current call I'm on), launches the music player, and launches Google Voice app..sometimes cycles this several times. I've tried this with multiple handsets and headphones. Anyone else had this issue?
