The camera occasionally froze, also a times makes a buzzing sound, but works fine. It doesn't do this all the time.
A week or two ago, I got a message that moisture was in the port, but it wasn't - hadn't even been near liquid for multiple days. I think a factory reset fixed this issue. While it was saying moisture in port, it wouldn't allow wired charging so that concerned me at the time, as I prefer wired because it's quicker.
A few days ago - this issue alarmed me but thankfully it's gone now: as I was driving home, out of nowhere, the phone decided it would start typing a bunch of 888's almost like you leave your finger on or keep pressing 8. 888888... I would delete the 8's and do a voice message, or get into an email, but the 8888's would start up again. Then it wasn't letting me keep windows open. I would pick a folder on my home page and an app, it would open for a moment, then close it altogether. Samsung had me wipe the cache - which helped but the 8888s came back. So I did a full on factory reset and only brought back a few apps at a time. That reset was done I'd say several days ago and since then - no more issues. Typing now with a bluetooth keyboard and not a problem.
I'm used to Samsungs having quirks here and there and as long as they are not long lasting or multiple quirks arise within a short period, I'm fine. Absolutely love the phone.
