Howdy. I just bought a second hand iPhone 6S and it comes with a weird stain where the arrows point. Do you think it's an issue of a burnt circuit or is the screen wet?
MacBook Pro 2011 - 2013 (GPU failure, Apple replaced with next gen MacBook Pro)
MacBook Pro 2013 - 2017 (Staingate, still using it)
MacBook Pro 2017 - 2018 Touch Bar (Speaker failure/muffled, sent in for warranty)
In my opinion, any recall by Apple or any replacement is not a cure or solution...
