@bb052609 @7f2d5fda @c0d5fe1a This is an iPhone with a Lightning port? If so, I had the same issue and was able to remedy it by using a $10 cleaning kit I got from Amazon. https://amzn.to/46cxIIe for that.

I'm pretty easy on my phone, but that slot gets stuff in it. This is apparently a common issue, according to YouTube. 

 @ce37034b @7f2d5fda @c0d5fe1a Thanks! I used a plastic dental pick and pulled out what looked like a small amount of fuzz, and it has worked twice now.

So with six days left on the warranty, I'm trying to decide whether to call it fixed or send it in for repairs.
