Sarah... This sounds a little different from what I've been experiencing. I ve never used a headset so I don't know if it's related. This "static" happens occasionally when I end a call -- when speakerphone has been active on the call. And, thankfully, the problem hasn't seemed to increase in regularity over time. It's pretty much stayed the same since I first presented the issue. Doesn't happen on every call...and often I'll go a week, two or three without any such event at all. The sound doesn't last long -- 5 or 10 seconds, and since it only happens when a call has ended, whoever I had been speaking to during the call never hears it. I don't believe it has happened when I've been listening to music...either directly on my phone or when it's been connected via a Bluetooth speaker -- just after ending calls.
