Noticed it today on a 7-month-old laptop. Annoying.
What baffles me is that I don’t recognise anything I use as having the same UI as the faint lines that have appeared on my screen. An area of pinstripe on the left, then columns of buttons on the right. No website or app I use looks like that.
Plus, my screen is configured to turn off after 3 minutes. It’s never left on 
I’ll send it off for Samsung to take a look at it anyway. It almost looks like some BIOS diagnostic type screen.
My iPhone also has OLED burn in, which sucks because I thought Apple once claimed they “solved” burn in by using algorithms to have the pixels constantly shifting to avoid it.
I’m lazy, but I do need to engage my Apple Care and get it fixed before it’s too late (my iPhone 15 Pro Max) as it annoys me periodically.
It’s sad, but I know the always on display is what caused my issue. I use the screen black with green text.
It’s weird. My last laptop, another Samsung, was OLED too, used that the same way for three years and had no issues. 
they swap it out, 'cos it’s annoying. Especially editing photos.
Samsung has gone off to be looked at. Now forced to use our MBA for a few days 
I’m gonna take your momentum and use that to propel me to get my iPhone fixed this weekend.
Good luck with your MBA; hopefully it’s Apple Silicon at least
Yeah, it’s an M1. It’s fine, I just prefer MS!
I’ve had burn-in on most screens over the years. One of the worst was a 22" LG wide screen monitor from the early 2000s, I used to play an MMORPG and the inventory windows burned into the screen and were visible when using the desktop and productivity apps. It would fade away again after a few days. In the end, I ended up putting an old 17" LCD on the computer and using it exclusively for the inventory windows when playing.
My first iMac, a first generation Intel 24" suffered as well, with the menu bar and Apple logo burned in (or long persistence of several days of non-use before they faded away again.
Although I can’t say I’ve noticed it on my current MacBook Pro or the 42" LG 4K display I use.
I’ve seen it at work on displays we used to show info in the buildings, but never on laptops before.
So it can go away after a few days? I’ve sent it off now anyway, wonder what they’ll say.
I finally made the appointment. Tomorrow I’m going to the Apple Store. Hopefully I can just walk out of the store with a new display on my current phone
Aaaaand 3 hours later: my phone was repaired for free!
Did they swap out the display panel?
Yeah. My phone had the same nicks & little scratches as it did prior to repair. But brand new front pane.
I didn’t get a chance to ask Apple but I wonder if having my phone repaired impacted the water resistance rating. I shower with my iPhone(for music!) pretty often, I was impressed when the water detector in the SIM tray wasn’t tripped. I don’t go out of my way to submerge the phone, obviously. But my phone definitely has been under water before. I once took it swimming with me to take some pictures of myself under water
I’m a bit worried maybe when they opened the phone (and presumably changed the adhesive) it impacted the IP68 rating. I suppose I’ll find out because I have 0 intention of changing my behavior
Looking hopeful for me, too. Just got this update…
‘A Samsung Expert has inspected your device and ordered the parts needed to complete your repair.’
I’ve found Samsung pretty good with support. No stores near me, but you raise a ticket, a courier turns up next day, they start work on it next business day and it’s back with you the following day, unless there is a wait for parts.
Laptop back, all fixed.
It was a faulty graphics card, according to the paperwork. It’s integrated, though, as it’s a Snapdragon PC
Anyway, the problem has gone away. Nice to have the OLED screen back, hard to go back to LCD on the Mac (although battery life is worse because of it).
