Hi all

I know there have been some other threads with touch screen issues, but I'll say from the start I don't have any Bixby remapper or anything similar.

I bought an Samsung Galaxy S8+ (G955FD) a bit over a month ago. Though it was purchased via eBay, it came completely sealed and brand new. I have started recently (last 3 weeks or so) some weird touch screen issues. Mostly when pinch-to-zoom, long-presses or even regular scrolling through a feed (especially when doing it slower). Below are a bunch of examples showing the behavior and I've been wondering whether anyone else experiences anything like this, or I should definitely RMA it? I've done a few factory resets and the issue has not been fixed.

PS: I am currently in discussions with the seller since it was posted with 1 year warranty, but it seems it's going to take me forever to get it fixed or replaced besides I'm afraid they will say "no issues found".
