Holy Crap...I think just tumbled upon a possible fix for the aggressive yellow tone on the iPhone X screen (with True Tone ON) !!!

This is no joke. Try this. Go to Settings > Display & Brightness > Night Shift and slide the Colour Temperature slider all the way to the left (‘less warm’). The Night Shift setting btw is still OFF.

On my phone the screen immediately turned a normal colour...the way it is on my iPhone 8 Plus with True Tone ON. No extreme yellow tone anymore.

It looks like somehow the ‘colour temperature’ setting was activate even with Night Shift OFF!!!

Try it and let us know...

Btw can’t get the old yellow screen back anymore whatever I try now using the slider. Weird issue but very glad to have a normal and great looking screen again!

Give it as feedback to Apple/Report as bug :D
 
Worked as well. I saw your post in the other thread. First I thought it was a placebo effect, but staring at my terrible over blue PC screen at work and then at my X doesn't make the latter look yellowish at all.

That does seem to help but I think it is better on my iPad Pro...will compare later.
 
No effect as soon as you take your finger off the slider as this is the Night Shift setting and NS is still off!
 
I don't think this is actually doing anything to the screen itself. I think the brief flash of intense yellow from having your finger on the Night Shift slider is actually "resetting" your brain's setpoint for white balance.

Almost as if your brain's visual cortex is going, "Holy crap that's yellow..." *takes finger off Night Shift slider* "Ah, that's actually white now. Sweet."

This only works very briefly for me; if I then look at my desktop monitors and back at the iPhone X, it's right back to looking way too yellow with True Tone enabled.

Nope it did really work. No placebo here. Before the screen on my X was extremely yellow (the typical dark yellow you normally get with night shift enabled). After this change the screen now is normal true tone colour, as it is on my iphone 8 Plus. A massive difference, on my iphone X at least.

It seems to differ from phone to phone though, and maybe some will see their screen with true tone on as too yellow anyway, and expect more blue/cool white. This is not the difference I'm discussing here though.
 
Regardless what you may think this absolutely is no nonsense. Very happy the screen on my iPhone X is now as it should be. I have reported the bug.

For anyone...if it doesn’t work then at least it was worth a try.

It’s not going to work for some, and not for others. It’s all or none. And it is none, objectively.

If some people perceive a change, it’s not because the device has changed in any way. It’s the placebo effect, or the fact that they briefly saw a yellower screen, and are experiencing the rebound effect. Same as when you use nightshift for a period of time, then then it off, and your screen looks crazy blue.

This method does absolutely nothing.
 
You are wrong and ignorant to boot. Myself I have noticed this very clearly...the screen tint changed to the normal warm-white colour tint, and hasn't changed back to the overly yellow tint since.

I am no novice, nor am I a troll. Others have clearly have the same experience, while others don't. Therefore it may work, and it may not. Anyone can try...nothing lost, possibly gained.

Let's keep it civilised please, and refrain from generalising remarks.

Do I need to keep true-tone on or off?

Do I need to keep true-tone on or off after applying the night shift settings?

This applies to True Tone setting ON.

Just to reiterate...the True Tone setting is not the issue here. It's the overly aggresive yellow tint when using True Tone (compared to say the screen with True Tone ON on an iPhone 8 Plus), and probably caused by the Night Shift option automatically activated in the background somehow (although it seems to be set to OFF). I have already reported this to Apple.

Pretty cool.

I don’t off True Tone due to the extreme yellowing. With Night Shift manually enabled, you can basically adjust the True Tone yellowing.

Cool find.

Pictures please, before and after. I will admit it is not as extremely yellow as before but the yellow tone is still quite noticeable.

For those where it is making no difference at all, I would like to see those pictures too.
