I’ve changed and iPhone 6 battery and after closing the LCD back in place, a blueish dot appears a cm above the home button. while the screen is still lifted (not yet seated with the frame), this blue dot does not appear, only when it is properly seated with the frame. I’ve checked that there are no loose screws running around, and cleaned thoroughly any ideas?
This is a pressure spot caused by uneven surface. You must reseat the dock of any high point. You will find something that you have missed
