I’ve been researching it. It’s talked about a lot for the X. Apparently because the screen is a retina sensitive oled screen which is great for crisp beautiful images, but can burn an image if it’s on for a long time, if the brightness is set high.
It says somewhere keeping Auto brightness turned on helps this not to happen. Yet it’s not highly publicized, in fact it’s hidden deep in info touting how great this particular screen is!
The only warning about auto brightness I’ve seen over and over is it saves battery life.
Its absurd and I’m furious!
I have this burn now too.
Naturally the keyboard image will be on for a long time if you compose lots of notes, emails, or are a writer!!
Apple should warn us while we tap away on the keyboard, "Caution, keeping your keyboard on for an extended period can burn its image into your screen”
But of course they wouldn’t do that because everyone uses their phone to write! That would be like saying you have a "not very smart” smart phone.
Instead they hide the info in a happy-What a wonderful screen you have-article that nobody reads. Now let’s see if they replace my phone.
