I seem to be having intermittent issues when trying to make a phone call. I have had problems where the headset doesn't work if I put it in AFTER the call is started. I also have had problems where the headset is in, but when I make a call it defaults to speaker and is stuck on it. I've tried to make a regular phone call(with no headset or bluetooth) and it defaults to speaker and refuses to switch to anything else. I also had a problem tonight where the headset was in, but the microphone on the phone was still turned on. I've had issues with bluetooth headset sound quality (not on my end, but from whoever I'm talking to). Not to mention issues with pairing (its paired, starts a call, but fails to stay paired). I am wondering if this is isolated to my phone or a bigger problem. Anyone else experiencing any of these issues? And, slightly differently, I've had issues where the sounds (like keyboard, on/off, etc.) stop working. Usually after using Siri.
