Galaxy S23 Ultra CAN HURT YOUR EYES

[@ChristianGolca]

Thank you for explaining this in such great detail! I haven’t been able to use any smartphone with an OLED display because of PWM. Not only do I get eye pain and headaches but also terribly dizzy. My current and only smartphone that I can use is the iPhone SE since it has an LCD display.

[@allkindsofthings1497]

Bright, vivid colors can be a strain on the eyes. On iPhone: First set the phone's brightness to 100% (to compensate for the next step which make it darker), Then go to Settings, Accessibility, Display. Set the Reduce whitepoint setting to a high value. This reduces the intensity of bright colors. Myself I use 95%. If you find it too dark you need to use a lower value than 95 %. This brings brightness back.

I'm more afraid of pulse width modulation

[@TopShelfRippin]

@@LizardKing-io9vithe op's comment fixes the pwm, for the most part.

[@allkindsofthings1497]

It is not only PWM. I find that I get problems with screens (both phone and computer) when the colors are too vivid and exaggerated. I just found this today and am testing it: From Android Settings, tap Display, and then tap Screen mode. Tap Natural (or Basic). Don't choose Vivid. Also under Settings, Accessibility, Display there may be some setting affecting color. My Android phone is old so can't check it now.

Thanks for the explanation. I actually like the Samsung Galaxy S23 Ultra before until I figured out that it has this major flaw, which is a low frequency PWM dimming and its a BIG problem because not all people are suitable for such phones with displays like this. I have a Xiaomi POCO X3 NFC from 2020, it has an IPS LCD, BUT... it has a 2358Hz High frequency PWM dimming at low brightness levels and I've been using it for years now but haven't experienced migraines or anything. I hope Apple and Samsung will use high frequency PWM dimming in their future phones.

One comment said this problem goes away when you turn on the extra dim function on your s 23 ultra. Is that true? I want to buy it but I of course don't want to hurt my eyes!? 🤔

[@FX_A12]

​@@loveistheanswer5924No, it doesn't go away. S23U user here. You either try to get used to it or change the device. You won't really be able to tell if you're sensitive or not unless you buy the phone and use it. Also I'm just sensitive to most of the newer screens in general for some reason so I might get used to it, time will tell. I had the same issues with my 12.9 inch ipad pro with mini led but I got used to the screen, so who knows 🤷‍♂️

[@EllisKaiXOXO]

I tried recording from another phone but I couldn't see the flickering. My eyes would only hurt if I would play mobile games for about 18 hrs without rest - not limited to S23. So I didn't get it why my teammate (iphone user) asked me if my eyes don't hurt yet one time that he had to stop playing when we only played about 3 hrs. Perhaps it depends on different person and the best way out of it is to give your eyes rest. I think it's not only on S23 Ultra or smartphones.

My phone were a Redmi Note 10 5G. I used lot of IPS LCD display on any phone (Nokia 3 2017, iPhone 5, Samsung Galaxy Note 10.1 inches tablet and actual Redmi Note 10 5G). I prefer LCD display to AMOLED or OLED, except if it's 90 or 120 Hz.

Samsung is pissing me off. I love the brand but they're starting to treat people worse than Apple

[@exscape]

Bit of an error around 3:16, but it doesn't change the main point of the video at all. The frequency doesn't change when you dim down with PWM; the pulse width does (hence the name, Pulse Width Modulation). The frequency is constant. Basically, at 100% brightness the screen is always at max brightness, but at lower values, it rapidly switches between max brightness and a lower value (possibly even having it entirely off). The lower the brightness, the longer the screen stays at the lower brightness every cycle. So it might be 50% on/50% off at a mid brightness, and 10% on/90% off at a low brightness setting. A lower pulse width is generally more annoying than a higher one.

[@deschubby183]

No pain and no fatigue after using it for extended period. Is it because S23 using Dynamic amoled instead of super amoled (A15, S7)? or because samsung using higher pwm frequency default to reach peak brightness their galaxy s23? This is so annoying.

Just bought Galaxy S24, can confirm that the problem exists (to my big surprise and disappointment). My mother does not see or feel any difference, but I feel like it is painful to use when compared to my iPhone 6S (IPS) or even to my older Samsung Galaxy S4. The latter I haven't used for a few years, but don't remember any flicker problems like that. S24 review on notebookcheck website says: "Samsung uses the PWM modulation type including screen flickering to regulate the screen brightness. In our measurement with the oscilloscope, the amplitude curve is very uniform across the entire brightness spectrum and fluctuates constantly between 240 Hz and 480 Hz" (which should be better when compared to Pixel 8 or budget galaxies like A25 or A55 [120 Hz to 240 Hz]. It seems like the advertised 2600 nits of S24 comes to its disadvantage (possibly), as you will tend to lower the brightness even more which will produce even more flicker (?). My head does not hurt, but my eyes react immediately with fatigue. Terrible. Also white balance is off on S24, when compared to iPhone 6S, colors seem yellowish at least with 'Natural' color profile.

I used S22 then tried VIVO X90 pro and again (because of the dimensions) s23. With s22, huge migraines, few days with Vivo, everything okay, then two days with S23 and again migraine :-( so I have to use some of the Chinese brands with high PWM or even DC dimming ( what I know, ,,small" Xiaomi 13 use it)

[@graham1155]

Dark mode helped, I still returned the device though

[@yazouruaim694]

Why?

[@graham1155]

@YazouruAiM two reasons mainly, the first being that the screen is one of the worst for pwm flicker. Secondly, the cameras, after extensive testing there are too many issues, shutter lag, yes this can be improved, however, at the expense of focus. Faces are very often over processed and fake. There are far better options available for the price

@@graham1155 thanks to your opinion, but i think screen is not actually a problem since there's more Millions of user that didn't complain it's just probably a rare case or something, idk.

[@graham1155]

@@yazouruaim694 I’d have to disagree , have a look on KZbin for a video titles “s23 ultra can hurt your eyes” . This is a well known issue with Samsung oled screens, pixel 7 also. The slower the flicker the worse it is, the ultra flickers at 240hz. The purpose of pwm is how the screen brightness is controlled, which is a cheaper option to dc dimming found in other handsets. Some of the Chinese phones have pwm of 2000hz, which is far kinder to the eyes

[@FSWEB2011]

Best video about this topic. So well explained. I cannot understand how this is legal...in Europe there are tonnes of laws and prohibitions but something like this is not addressed... On a 1000 euros + phone this is unacceptable. I used and IPS phone until I purchased the s23u...big mistake. If i would have known (warning in the box, more youtubers explaining etc) i wouldn't have spent so much money... Unfortunately i didnt relate my eye issues with the s23u until it was too late, and couldnt return it. My (partial) solution: pump up the brightness to 60-70% during the day and avoid using the phone at night...and keeping it over 50cm from my eyes while watching. Battery time obviously affected and not being able to use the phone during afternoon-night....not good. Cant wait to sell it (at a huge loss) but there you go. Problem i see is that reviews not mentioning this and only mentioning the 'good things' are affecting peoples eyes... You might think 'I am fine' but you never know now how this is affecting your eyes....

[@VariantAEC]

Lol. I'm pretty sure if this were a real issue, at least a few million users would've reported it over the past 10 years. It has only become an issue because people are now aware they can blame their headaches on something... but many of those people are using displays with much lower flicker rates... so... Is Samsung (and any manufacturer using their displays, including Apple) good or bad? Is this really what is causing your problem, or is it just what you believe is the easiest thing to point your finger at today?

[@VariantAEC]

You literally explained that PWM is used to prolong the life expectancy of the diodes at the top of the video... then at the end of the video you act as if DC dimming is the answer... 🤦‍♂️

[@WrexBF]

What's the point of having a phone that ''in theory'' lasts longer but hurts your eyes?

[@VariantAEC]

@@WrexBF It doesn't hurt your eyes. Or maybe it does _hurt your_ eyes (even thought it really still doesn't hurt your eyes), but it doesn't hurt my eyes. So, I'd take the much prolonged battery life. Full disclosure: I can run my phone at 120FPS with surface updates being shown (the pink yellow flashing screen) with no issues and only a minor impact on the readability of on-screen content. Pretty sure most people can't deal with that at all. Sorry to say this but this so-calles constant power "DC dimming" feature still shows flicker to me. The S23U does use DC dimming over a certain brightness value, but the display flicker can also be caused by swapping the pixel content. Even when forcing low refresh rates (1hz) and max brightness there are dozens of sub-second flickers. This happens on all screen types. LCD displays with LED backlights using DC power for all facets of the display also show this phenomenon. LED lightbulbs with the circuitry to maintain "constant" brightness also flicker despite what is noted. Seriously, just film the surroundings of any synthetically 'well-lit' room at anywhere from 240 to 1,000FPS and watch how the light oscillates between full-bright and a more limited brightness value. Incandescent and fluorescent bulbs are the same way. Sorry that it strikes me as odd that you somehow know it's these new screens giving you headaches when literally >98% of artificial lighting is this way too. Shoot, even gas lighting halogen and sodium lamps and neon signage (as if fluorescent lights don't count as gas lamps) also oscillate brightness in accordance to the AC grid's frequency. None of that is somehow of any consequence to you though... right? It's all these new screen's fault. There are only a few truely stable DC lighting options... take the LED light on the backs of some phones... yeah, not all because not even all of those operate at full-brightness 100% of the time. Anyway. This new trend of disliking PWM is a joke experienced by no one. Literally all OLEDs and most mobile displays were PWM for more than a decade. That is literally tens of billions of phones, never mind PWM being used in every other display type for *FAR LONGER* in all manner of devices big and small after CRT was replaced which itself also flickers noticably (despite the fact that the electron beam updates pixels within a single frame at a far, far faster frequency than modern displays can currently). Disliking PWM is the new electromagnetic hypersensitivity craze of the mid 90s to early 00s (and is still alive today). The reality is, for people like me who actually can determine where electrical signals are originating from... this isn't at all a problem or even mildly annoying at all. When the power goes out things get quieter and darker in a way normal humans simply can't understand or ever experience. I can tell you that power outages are freaky and that's coming from a person that has only lived in any major cities for a fairly short period of my life. Mostly I've lived in less urban areas where the effects of the grid are still incredibly obvious to me... but what else would you expect when I can tell if there are powerful electrical storms hundreds of miles away? PWM is really being used in most displays. It's not an issue coming from someone that can see, hear, and otherwise sense a wider array of electromagnetic, (and probably sonic) frequencies as well as a much higher flicker fusion threshold.

I will switch to Xiaom next year if Samsung does not fix this! DC Dimming or higher PWM Frequency! Atleast 1920 Hertz! Xiaomi 13 Ultra now has it! But i hope Xiaomi also upgrades it higher. 2160 Hertz or even 3125 Hertz that is risk free. 💪😎💪 Honor 90 already has 3840 Hertz? Even better! Extra good! 100% zero flicker! 😱 But yeah! Samsung must fix this! DC Dimming would be very nice, but it looks bad. Colours look off. So higher PWM would be nicer. If they just could fix DC Dimming too to look better. 😁
