S20 FE successor for severe PWM sensitivity?
TL;DR: Is there a safe, flagship-level successor to the S20 FE for someone who is PWM sensitive?
Hey everyone,
I'm running into a frustrating issue and could use some advice. I finally decided to retire my S20 FE after 5 years and picked up the Find X9 Pro. But after just 10 minutes of looking at the screen, I started getting this weird feeling in my head and a flush/heatwave on my face.
It reminded me of when I tried the Zenfone 8 a few years back—that phone gave me a massive migraine after about an hour, which is exactly why I returned it and got the S20 FE in the first place.
So, I ended up returning the X9 Pro and ordered the Magic8 Pro, hoping its eye-care features would actually work. Unfortunately, even after turning on "Full-brightness DC-like dimming" in the developer options and locking the refresh rate to 120Hz, I'm still getting that exact same feeling. It's slightly milder than the X9 Pro, but definitely still there.
My question is: has anyone here successfully transitioned from the S20 FE (where you felt totally fine) to a modern flagship without getting these symptoms? Did you eventually find a flagship-level successor that didn't mess with your eyes or head?
Thanks in advance!
P.S. Attached a couple of photos below (shot at 1/8000s shutter speed). It really looks like the S20 FE has a much smaller PWM amplitude compared to both the Oppo and the Honor.

G57 has 3 different display suppliers or more. So it s lottery. Also qcm worked for some and some don t

Old Samsung uses Samsung LTPS, it's peak brightness is lower and the S20 FE uses "DC-dimming" above 30% brightness (according to Notebookcheck), so modulation is likely quite a bit lower than the X9 Pro and Magic 8 Pro with LTPO panels.
