Weird OLED display (SX Max)
I just bought an iPhone XS-Max and with my glasses on - everything looks like a 3D picture when you are not wearing 3D glasses. Has anyone else noticed this?!
iPhone XS
I've seen some XS Max screens and, in my opinion, that's a beautiful screen (with or without glasses).
I didn't noticed any 3D effect on them.
To feel more comfortable, you could visit the shop where you bought it and look at some other XS Max screens, checking if yours is different / defective.
