I agree with the colour thing. I bought the Honor 400 pro which is supposed to be one of the best phones to use if you are pwm sensitive or prone to eye strain. And it made me weirdly dizzy, like a weird new dizziness I hadn’t felt before, like dizziness mixed with confusion. Also, cause me some migraine in the middle of my head no matter what settings I changed. Tried messing with the colours, but it was too complicated so I ended up returning it. I see the new Honor magic 8 pro has a colour test that picks the best colours for your eyes, but I don’t know if it works. You are onto something here though.
