Display issue on my iphone when its on low light mode or night mode.

That could be a display issue if it does not appear in the photo. You can try powering the phone off and back on again. If that does not help, I suggest that you contact Apple Support for assistance. Use the link at the top of the page.

I am having the same issue. chat support told me to do factory reset. still happening. trying to get genius bar reservation. have to go through chat. no appointments to be seen online. i guess because they are limiting in person.

it's a pain because i've had to contact them twice now and the chat guy has to get a supervisor to make an appointment.

Posting a photo, especially one that small, does not tell anyone what the display issue. You need to explain it.
