When on a call every time I get a notification not only does the phone vibrate (which I want) but it produces a loud electronic hum through the earpiece (Like Doooooooo). So loud in fact that I have to remove the phone from my ear. The few times I have kept it there and endured the pain it completely blocks and overrides anything the caller is saying. Is this normal for everyone or do I have a "special" phone? Is there a fix? The obvious workaround would be to turn notification vibration off. However, I keep my phone on silent 99% of the time and need that vibration to alert me of emails, texts, etc. It would be a giant pain in the ass to have to turn that off every time I answered or made a call. Any thoughts?
