Curious if anyone else had this issue. I was using my iPhone the other day surfing with Safari on EDGE and then all of a sudden the speaker let out this really LOUD constast high pitch sound. I tried exiting Safari and it didn't go away. So i tried to lock the phone, but it wouldn't lock. I had to hold the lock button to power it off, but before I could slide my finger to power it off, it stopped. The sound went on for a good 30 seconds.
It's been fine for the last few days, but I am curious if anyone else has heard this noise?
