Mines the same as your video. I don't want to change it yet as I may get a worse screen or battery. I figure I'll phone in for a replacement some time in the year and send a video showing the noise like yours. It's clearly not right on a £600 phone
Oh If you turn it over and tap it goes away right?
Thanks for taking the time to post.
I can understand not wanting to chance a replacement but the way I see it is if there's something wrong with the replacement like a bad screen or hardware issue, at least it'll be a symptom that verizon can't just say "is normal" like this one... not to mention, I'm going to check the phones side-by-side when the new one comes and make sure it doesn't have any issues right out of the box.
I will be purchasing an applecare+ warranty when I get my new one and I'm going to bypass my carrier (verizon) for support/service. I am letting verizon try to make it right this time... but they're one of those companies that's getting so big, it's starting to degrade customer service.
Interesting yours is EXACTLY as bad as mine is though...
