My iPhone 6 has developed a very annoying fault over the last couple of months. There are a 5 white stuck pixels (although it actually looks like holes in the screen and the backlight is shining through). It essentially looks like someone someone has stuck a small screw driver through the screen (although nothing has pierced the screen and the glass is fine). It is almost certainly a hardware fault and I don't have applecare +. Will I have to pay for the repair or is this a common issue that Apple know about and will replace FOC? Thanks in advance!
