I was watching some videos on my new iPhone 6 Plus and noticed a stuck red pixel. The weird thing is that the pixel will change to all other colors except when it's a dark color, which is when it's stuck as red. I also noticed when the screen brightness is turned to 100%, the pixel operates as normally then too. It's very weird. Do you think it's worth trying to get it replaced? I could try and keep the brightness always at 100%, but it's starting to hurt my eyes. I'm hoping it fixes itself soon but I also don't want to swap my phone for a worse one, with bigger problems. Thoughts?
