I posted a video when the X was first launched. About how the X gave me headaches. That video is STILL getting comments to this day from people who didn't know why they were getting headaches when using any device with Apple's OLED screens. There are also some Android users out there who have that problem. It's not just "a select few". These screens are very bad for a lot of people. That said, I will try to preorder a 12 Mini and test it out. In my previous test, it took two days for me to show symptoms. The 14 day return policy will come in handy. If the 12 mini doesn't work, I will be getting an iPhone 11. (Using an XR right now without problems. Also my home is full of LED lights, no problems either).
