Hey all, So long story short: got a Samsung S7 edge last night at the local BestBuy mobile kiosk ($100 off smartphone sale) to replace my old iphone 5s. Wanted to try something new. Suffice it to say - it was defective so I said screw it and replaced it with an iPhone 6s 64 gb today. Fast forward about an hour and I noticed a loud buzzing/electrical sound while trying to make a call with the new iPhone. Made a few calls and everyone said my voice sounded staticy - and I could barely understand them as well. Brought it back to the store and the employee tested it by calling their phone. Surprise surprise - my phone started screeching during their call. Almost like it was feed-backing on itself. They replaced it without question. However, they said they've never seen this issue before. Just curious if anyone else out there has had it? The replacement phone still has a slight weird static/electric noise when i listen carefully (even outside of a call, just sitting on the homescreen with the phone to my ear) but other than that it seems fine. I also noticed my GF's phone has the same weird static/buzzing noise coming from it. So I guess that is a normal 6s thing? Anyway, just curious if anyone has experienced a similar screeching/static noise. Thanks!
