I’m in the same boat as you regarding phones. My sons are computer nerds though, and could probably tell me a lot. Maybe I can ask them tonight after work.
Or maybe some computer and/or medical experts here could clue us in. But I’ve looked up articles about computer monitors and seizures, and it definitely is an issue for people with photosensitive epilepsy.
Assuming you'd post about it, do please ping me to whatever they might have to say .. thanks.
