yes it is on. do you recommend keeping it on or disable ?
anandtech review went up today, a really good read for those interested in the technicals around these new phones.
I personally really like the True Tone and much prefer it on than off but if you're not used to it I can imagine thinking the screen was a bit funny as will often look a bit warm more than not.
Give it a go with a day on and day off and see how you feel. The screen is too cold for me when it's not on
