reaganry I certainly agree that an ad-hoc thread about the general concept of the usability of smartphones over almost a decade is not the most productive way to discuss and organize such information

      I managed to try the Oppo find X8 (not Pro) international version.

      straight away gave me bad feeling, caused a bit of nausea, even worse than iphone 14 pro 🙁

      I have had another success with an older phone I had lying around that I tested, it was an old Moto G8 Pro, it caused significant eye train, I activated developer options, and disabled HW rendering, and it actually made it usable. So if you ave an Android that causes you issue, it's worth a shot. I an 2 for 3 trying it.

        moto g55 not good (same as g54 and g75). Not mine feedback, but from sensitive users.

        Report on Poco x4 gt. I bought a Poco x4 gt to see if it is good for my situation of eye pain and eye fatigue etc, all problems caused by ledstrain. And well, after some configurations the result was that I got a 70% improvement in eye fatigue, it's not perfect, but I can use it for 10 minutes, 10 minutes in which I do everything I need to with a smartphone.

        The next step is to save money to buy a Xiaomi 14 to see if it solves my problem.
        I don't know if my report is useful, but if it helps someone...

            JOSEUISLEY someone on the tg group said the xiaomi 14 dithers on every color mode under a microscope. Oppo X8 does too. OnePlus 13 I think does not. Btw if anyone is curious all flagship Xperia phones use a 8+2 frc panel. One of the newer motos I think it was the 50 ultra but supposedly does not dither on vibrant color mode but does on all of the others which is weird

                jordan Really, whoever can try it and return it so as not to lose money. I believe that in our situation everything is valid. But the Xioami 14 I'm curious to try.

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

                  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.

                      qb74 I definitely think the phosphors are part of it. I think the light emitted is far from natural and that the colors are way to intense. Most devices are using pfs/ksf if they can display wide color gamut.

                        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.

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