Various iPhone 5 users have complained about a lens flare that affects photographs when the device is pointed towards the sun or bright lights.
Apple posted a support article on its website, advising users to reposition their camera when taking pictures.
Now a green glow is reportedly appearing from the edges of the screen on some devices.
The problem was first reported by The Register: “This time a green glow described as a plasma bleed from the edges of the screen is appearing on some of the new handsets.
The green light is momentary, and appears on the unlock screen just after the iPhone has been “woken” from a longish sleep.”
The publication writes that this issue is most likely connected to the hardware, not the software, as it is described as a “sort of warming up” issue.
Apple has yet to comment on the subject.
