Its not quite like that with Oled/amoled, I believe. You have pixels that light up in a different way to Lcd.
Think about what you've asked, if you have " burn", that burn would assert itself upon and over any content that you are currently watching.
Consider that you opened Samsung Notes, and chose making a new note, with a white background, anything " burned" should be "ghosted" over your current white screen ,I believe.
Long time ago, I'd do silly things like, find test settings that displayed an all green screen, or, all red, or all blue, just a full screen of whatever colour you )chose to display to test your pixel purity.
But you know, I was tempting fate, because if there were any dead pixels on my phone, they must be where I couldn't notice them and I was happy. Now if I'd found any, it would have made me unhappy with what I were blissfully happy with, thankfully, there were none.
Similarly if you are happy with your phone, embrace that.
There are, mixed amongst public consumers, on any popular public perception/opinion forming tech website, operative from competing rival tech companies that embed themselves, to give negative takes and stories concerning products that it is their job to stop succeeding. A phrase you could use is... a negative PR department.
They start a story, requote it somewhere else, then have someone else agree that they have the same problem, and it becomes a well know circulation.
Years ago I had that happen over Samsungs first watch, the Gear S, it was "Woe" for everything. Yet, I still have my watch today, no burn in, the strap only broke 2 YEARS ago, and it still has its original battery in it. No cracks, no damage.
Similarly many years ago, a particular super store brought out a tablet for next to nothing that competed with apples 8 inch "i" thing.
The Asus cheapo had more ram, a better screen and many other better upgraded faculties, at more than 200% less price. You could not get the cheapo's for love nor money, it was bang, out of stock.
Out of stick or not, amongst all the desperate people buying them FOR THEIR KIDS", it started.
The internet became full of apple justification. How the "i" was superior, how the battery would fall out of that Asus,and all the other negatives that were spewed across the web.
Guess what, I still bought one, I still have it, it still charges to 99%, and not one of the negatives took place.
It would be a pain but, I can photograph both watch and tablet to substantiate.
What I'm saying is, there ARE genuine problems with tech pieces, and every model on every production line, from EVERY manufacturer has them, it's just that if you look for them you're going to make yourself miserable.
If you, ( Anyone.) has a problem, it obviously NEEDS addressing, but trying to discern real problems from fake ones can be impossible, and wearying, espescially if you haven"t got the problem.
So its best to just enjoy our phones, come on here and look for missed features, learn and help each other, and be aware of certain mistakes that other poor people have made in saving me from doing the same.
Also hopefully if we can all be bothered to engage, when its needed, by BULK, we can try to apply customer pressure on Samsung where it may be needed,to provoke change, or indeed sometimes reversal.
I'm a very fortunate person in that currently, most, if not all, the major problems I read of on this helpful site, do not appear to affect my phone, but, I do take singular care of it in going through every setting when I get a new phone, charging between 10 and 80%, and I have not yet updated since 6.1.
I' ve also turned off quick charge and don't leave the phone to charge overnight, just don't seem natural to me.
Anyway thank you for your reply, and to all the other people on here who post such interesting problems and solutions, bless you all
