Galaxy S23 Ultra CAN HURT YOUR EYES

I discovered that have migraines from new ips displays. So i think that there some another problem, except pwm. For example realme c 55, honor 8a etc – like welding to my eyes.

I am returning an S23 because it hurts my eyes.
I was stunned to find your video.
Thank you for your cleear explanation. My eyes are still ok.

Does it happen on iphone as well ?

I hate samsung phones. They have always hurt my eyes. Samsung tablets are the same. Whether Samsung tablet or phone, Samsung devices always cause my eyes to hurt. I don't even think about Samsung phones or devices when I am thinking about buying a phone. There is something about samsung devices that my eyes cant endure.

Companies are keeping this matter secret for their own benefit. The cost of manufacturing OLED screens is low. People do not understand this matter.
Anyone who suffers from migraines or depression should change their phone to the iPhone 11 and will see their health will improving

I will publish a study soon on the reason for the large number of suicides in South Korea. One of the reasons is the large amount of depression caused by AMOLED screens.
because South Korea only has AMOLED screens for all device !!!

This poblem has been solved by Chinese screen factory.I don't know why western world look down on eye health.Eyes protect has been the most important feather in chinese smartphone.2K+LTPO+non-flicker+low blue-ray+10bit and good color+low power = chinese flagship smartphone

Hello from Russia 😂

My eyes hurt and i got head ache dang it guess what I just got

i wonder why top tech channels like mrwhosetheboss or mkbhd don't talk about this issue. it's a huge issue. i don't want to believe that they were paid to keep their mouth shut on this. also, if anyone looking for a good LCD phone, take a look at the REalme 9 5G SE. I am using it for about a year, and it's a great device with snapdragon 778g and 6/8 gb ram. camera is not that great, but the performance is amazing

I have an s23 ultra... and my computer monitor is a huge oled.. i can stare at my monitor all day no issues. I check something on my phone for 5 minutes and suddenly i cant read anything on my monitor for a couple minutes..

But the screen does not flicker the way you are showing it.

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... 🤦‍♂️

I was so happy to buy the s23 ultra and now I am very sad because of that reason! ☹️

So there is no solution to that? No App that changes that or anything else? 😕

we need mini-led smartphones with high pwm and some advantages of the Oled screens

Although to be fair, voltage regulators are just really fast PWM. But it can cause the display to malfunction at a lower voltage (like CPU).
But you can use "Extra Dim" setting on newer android version to avoid this (it reduces the pixel values instead of using the brightness control)

I had S 21 ultra and I wanted to change the phone, but I knew about PWM, and I understood why I always felt so bad. And although the desire to buy S 23 was great, I took Nothing phone 2 And what was my surprise when I felt that I had no fatigue in my eyes, because this phone does not have such a large PWM although it has an OLED display.

I found this video because my phone is making me feel like i am car sick with a headache. Not a great feeling.

5 days with s23 and handed it back to the store. my eyes couldn't stand it

Thanks

The only solution is to choose the smartphones with an IPS display which is hard to find nowadays when it comes to flagship devices.

I recommend the Xiaomi 13t series

👍👍👍

Pwm values for

S22U =240hz
iP12 pro = 245hz
Oneplus 9 pro =200hz
Pixel 7 pro =240hz
Nothing phone 1 = 120hz
…….
…+
+

But s23u in 240hz destroy your eyes 😂

Its not proved yet

I really need help, i use to have a galaxy A52s and i never had eye strain before, now i upgraded to a s23 and after a month is killing my eyes, sometimes i see a bit blurry everything, so i need to stop looking at the s23 screen for a few minutes and my eyes feels better again, now i need to replace my phone again T.T but which one? The A52s and this s23 supposedly are 120hz oled screens, but they feel way different. Now i need to chose the right one, to upgrade

A few months i have been abusing 😅 s23u and i have no problems whatsoever. Top feeling, always.

I actually have a problem with amoled screen flickering , I get headaches after using only half an hour , so Honor 90 with 3840 hz pwm dimming is a solution for me , but I doubt that 3840 hz Pwm dimming technology actually works in reality ?
Plese reply

Even I was a die hard fan of Samsung and already had used 4 Samsung phones in last 8 years . But just 5 months back I got affected with headache dizziness and eye straining even after a few minutes of phone usage.And my doctor suggested me to change the phone . I bought 14 plus afterwards and now am freed from all the hallucinations and headaches. I had opted out 14 pro models considering even it may cause some sort of eye strains. PWM least for 14 plus

Екрани отвратітельні остані роки, ДС дімінг чомусь видалили (хотя дайлиб можливіст. я готовий пожертвувати кольорма) за 2 роки користування айфона з олед попортив очі, треба цій проблемі зробити розголос для компаній щоб добавили ДСдіммінг

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.
😁

I have made this new list might help :
honor 90 3840Hz only start’s at 22% brightness
honor magic 5 pro 2160Hz only start’s at 22% brightness
zte z50s pro 2160Hz with complete DC dimming in developer option

Xiaomi 13 Ultra, Vivo X90 Pro and Honor Magic 5 Pro use great PWM.
1920 Hertz and 2160 hertz.
😁
Better than Samsung.

Як же я охуїв (здивувався), що в тебе є англомовний канал!

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.

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.

I have using s 22+ same happening with me too much head pain after using continuously for 4 hours previous I using Samsung a 30 it can’t be happen with it . Upgradeing to flagship gives me a problem and waste my money .

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.

I've been having this problem since I got the a 54 from Samsung then I got the s23 ultra and it got even worse a lot of headaches my eyes are super tired which phone u suggest thanks

5 months using s23 ultra, My eyes always got tired. Now going back to iPhone, no more problem. 😢

wtf samsung

Its been few days since I got my s23u. And Im noticing that my eye keeps hurt everyday. I didn't know the reason, then I started searching on web abut s23 display. And found this problem. I think im gonna switch.

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.

So, would it be better to buy midrange or flagship Xiaomi or OnePlus phones?

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.

说实话！由于利益驱使，iphone放弃了几乎历史最好的lcd手机，s23U，我一切都很满意，尤其照相、跟屏幕显示，虽然12g运存稍显不够用，对于它的价格，但是可以容忍。但是最后我仍然不舍的退货了，因为240hz的pwm对我的眼睛非常的不友好，没办法，期待把s23u的屏幕换成iphone8的lcd屏幕，如果再没有厂商这么做，我就要自己生产啦！！！！再创一个lcd的辉煌品牌！

Thank you for explaining great video i didnt have any problem with 12pro max 13 pro but s23u give me headaches feel me eyes dry and itchy . Why does it happen all of them have oled display..

I'm suffering from this headache, and I found one post about this in Twitter. I like your explanation but I hope we can find a solution about this 😢, I'm not sure if changing the phone will solve the issue. Ultra 23 is great phone and I enjoyed the experience but this flickers and headache 😑.

If you care about your eye, trust me don't use dark mode, I'd suffered this issue 4 years ago when dark mode were very good alternative for battery saving. If you reading text with dark mode, your pupils will works harder to keep try to focus on every fonts.
