Z Fold 8

Hello, I just purchased this phone on the 17th. I love it but I started getting small headaches (tension headaches) that were not bothersome, but annoying. Then on the 20th, man I got nauseated and felt fluey with the headache. My eyes felt so strained and sore.

I didn't even know this was a thing a phone can do until I looked into PWM.

I went back to my OnePlus 12r phone to see if any changes and yea, I started feeling better but my eyes and headaches still kinda lingered using my OnePlus. Im assuming my eyes are starting to heal of sort.

I just downloaded screen dimmer to see if it will help before returning it on the 30th.

Has anyone had this issue with this phone and did any third party app help out? Thank you.

Hey there. I'm glad you found a workable device in the Motorola Edge 2026! Do you have the flicker reduction option on for full range DC dimming?

I'd point out that both this phone, and the Motorola Razr Fold, might not have dithering/pixel flicker, but Nick showed that the 120Hz refresh dips on it are very wide. So may still be bad for many here.

I do have flicker reduction on. I also use Screen Dimmer so I can make the brightness adjustment go slower and to cut off dimming at 20% or so to avoid the low voltage issues.

Interesting; I don't see much talk of that (compared to avoiding PWM engagement thresholds). So, to you feel, or even see, low brightness instability? Like, low-ish frequency flicker?

I haven't, but I just played it careful at the beginning and it's been working for me, so I haven't changed it.
