Great info, I have a moto 5g stylus but have looked at trying to use a boox palma for most things
Usable Smartphones?

The worst ones with out a doubt are the Samsung Galaxy S21 and S22 Avoid at all costs the best for me and several of my friends are the Redmi Note 8 and Note 10s.

Does anyone here have a spectrometer or spectrophotometer to test out what color gamut modern LCD smartphones employ nowadays? In particular, in form of a spectral power distribution graph.
I'm curious whether the anecdotes of KSF/PFS & QD backlight causing eyestrain from desktop displays transfer over to LCD smartphones.

From this article, it seems that the LG G3 was the last LG phone with a old YAG phosphor W-LED backlight.
KSF/PFS panels became mainstream from 2014 onwards, I assume most LCD panels are WCG (wide color gamut) nowadays.
I think this might be a far bigger culprit than the witchhunting for dithering (FRC) implementations.

Asus gl702vm LCD laptop
Daylight dc1 tablet rlcd / tlcd
13t xiaomi amoled
Dell up2715k LCD which is the same panel as the older 5k iMac. I believe this panel uses the gb-r led backlight

This is great, interesting to see the SPD of a AMOLED display, thank you for sharing.
It reminds me of the graph of QD-OLED desktop displays.
I'd love to see a few smartphone SPD's collected in a spreadsheet, so we can start recommending different technologies to different potential eye strain concerns.
Other ones I could find:

Collecting this data, along with measuring G2G response times would be great for troubleshooting eye strain concerns.

JTL FWIW, I've found the posts from @Vividblu99 (and some others) to be very helpful. He generally lists the phones that he's tried and how well they've worked for him.
If we did start a new thread, maybe we could enforce a format something like:
- iphone SE: gave me headaches within 30 seconds of using it.
- iphone 15: usable for 10 minutes
- ...
This wouldn't be perfect. For instance, the same model doesn't always have identical hardware or software. And what works for one person might not work for another. But I think I would find it much more useful than the last year's worth of the current thread.
jordan I actually have to view the meters screen through a phones camera because the lcd on it bugs my brain.
I have to do the same thing when I need to do something on my son's phone. It's a pretty useful trick.
GregAtkinson it sure is! thats how I have to look at my moms phone if she shows me something. lol (iphone se 2020)

after years of trying devices without luck i got a honor 70 lite (as recommended by forum members) and it worked for me ,i recommend this phone for very sensitive people because it has no pwm and no dithering , the screen is a basic tft panel

I just got the new Bigme Hibreak Pro and it's a major step forward for e-ink phones:
I mainly use mine as a pocket reader and web device, but it reduces my iPhone screen time to almost zero.
I reviewed it here: https://www.reddit.com/r/ereader/comments/1j2tavy/bigme_hibreak_pro_pocket_reader_review/
No temporal dithering? All the mediatek devices I've used have all dithered.
I don't know, but when I've used devices with temporal dithering (e.g. macbooks) on e-ink screens the results have been very poor. Until it's switched off.
The optimisation on the Hibreak Pro is excellent, so I doubt this is an issue. They claim it is 'zero flicker'.
Clokwork Considering the device is Play Protect certified, what additional security concerns would there be if only using Play Store apps?
I’m not an expert on this, but I’ve seen comments suggesting that with Play certification, the CCP security risk is lower than that of the routers and networks the device connects through.
Security is good, but be realistic too.. The Chinese don't care about nobodies like us. Americans however, would add all of us to their databases.
