So I just bought a brand new iPhone 6S Plus and I'm curious if there are any known defects or problems associated with the 6S/6S Plus? Be it hardware/software or quality control etc. Also what else should I check or look out for that isn't "normal"? As I'm still within the 14 day window and can exchange or return it for another brand new device. Dead pixels? Does anyone have a website/app to check for dead pixels? Camera issues? Aren't people experiencing some issues with pictures being taken with the 6S/6S Plus? Performance issues? I've seen someone's iPhone 6S Plus was running a lot slower than the benchmark. What is the app to check how your iPhone is performing? Exterior blemishes? Screen issues? What else am I missing? Thanks everyone! Loving the phone so far!
