Burn in

No, after the warranty runs out the max brightness stays the same. It's just that if it burns one day after the warranty, your SOL. What's so hard to understand?

Samsung all they care about is making a phone that will knock your socks off with the best display on the market to buy it and that they set their tolerances on their phones best they can to make sure it lasts throughout the warranty period so that they don't lose money having to fix/replace parts.

It's not neglect if a user wants to max out their display... the person could have bad eyes and need a phone at max bright... Samsung set the max bright and auto bright so should be no issue. But yeah a user should maybe know that doesn't help in longevity maybe... that after the warranty he keeps doing it, you're increasing the chance of accelerated wear.

But you spend 1K on a phone and it burns in months because you want to set it bright? Come on.

Oh I understand I was kinda being sarcastic in my first statement. You said "Samsung sets the max brightness level so they do it within tolerances of the screen they feel it can handle at least during the warranty period" which makes it sound like it was just during the warranty period they set those tolerances for. But yeah if it's something odd like the OP stated then I can see that being an issue. Like I said if someone wants to use max brightness and keep the screen on for long periods of time then go for it just know that it increases the chance for burn in and decreases the displays longevity.
 
Id have to say a comma phone should be able to handle some serious brightness for at least a year or two. Especially with somewhat normal use including you tube and maybe gaming. Its ridiculous I have to worry about scratches, dropping my comma phone and updates, yes I know protect as best you can....... but burn in.......I say BS.
 
Here are a couple photos

I have note noticed any burn in and I hope I don't get it. My Note 8 had a pretty noticeable burn in.
 
Update. I contacted Samsung support and at first all they wanted to do is replace the screen. I wasn't happy with that option so option 2 is a refurbished phone. What are some of yalls recommendations?
Try and get savvy on auto brightness techniques and so forth to help you for preventing this occurrence in the future.
Edit just saw your pics. Looks like manufacturers defect and not screen burn in. Download display tester and use the #8080 gray background. Then reduce the brightness , it should show those defects up better. It's apparently the glue holding the screen in place from what I've seen elsewhere.

I downloaded the display tester and here's my findings. One is at 100% and the other at 50%.

Seems to be not related to screen burning. I've seen others with this issue elsewhere. It was apparently the glue holding the screen or something along those lines that was defective. Also, does this show all the time or when battery is at a certain level?
