240Hz PWM on Galaxy S23 series destroys your eyes and causes migraine. The most expensive brands, Samsung, iPhone, Google pixels have the worst PWM. On the other hand, Chinese brands have 1920Hz, 2160Hz, that is unacceptable.
Oled are quite slow compared to regular LED, meaning they cant flicker as much. Some laptop backlight can even flicker at 10khz The best option is to have DC dimming on 101 nits and up and to have 360-720hz PWM on 100 nits and lower. Brightess matters lower brightness PWM would definitely reduce eyestrain... going full DC is not an option as it result on very bad grey scale performance Big brands will probably never try going high 1920hz PWM because its inefficient, worse color and probably lower brightness
For everybody who read this, check notebook check pwm list, most of chinese brands lies to you about hight Hz, they have hight only on low 30% brightness in normal 2 times less than samsung s24 or iphone 15
I tried an app called OLED saver, you choose and it keep the phone brightness at a higher level pushing the PWM to be higher then it applies a filter on top to control the brightness, honestly it was an improvement on my S22 Ultra. But the best solution is to get a Chinese flagship phone the PWM is insane and using OnePlus, Realme, Xiaomi phones never gave me any headaches or eye fatigue.
As for the first point I figured out putting the screen brightness to the max and using 'reduce white point' as I have an iPhone is kind of working, but it's a trip to activate! I wonder why apple also doesn'thave a separate toggle from the control center for activating Night Shift and the fact it cannot be permanently put on, smh... I'm definetly getting a flagship chinese phone in a few months, it's going to save my eyes from dryness and eye fatigues.
@@mariocabaguiojr205 call me a paranoid but I'm 100% sure that it's a worldwide plot to ruin people's eyes, brain and health. Nothing will change, believe me.
PWM should be banned goodness. I don’t want to go through all of that . I just want one without it. Anyhow I just got a new phone so I’ll be keeping it until this nonsense is properly solved
Only solution I found was to swap out the OLED with an LCD on a used iPhone 13 (or any iPhone.) Makes no sense to buy new if you’re going to remove OEM parts and replace them with third party parts. Outside of faster battery drain it’s been fine. I’d recommend buying the Plus variant to counteract the higher battery drain wish I would have done that.
Love the iPhone 15 but after three weeks I had to go back to the LED IPhone 11, I was in serious agony. Just hope the manufacturers do something about this.
I am not sure why I felt eyes strained when I used galaxy S22,I didnt' know the reason. but I had to switch to an another mobile to get out of this pain. so I switched to an apple, I feel much more comfortable with this one, maybe my problem is not PMW. now I really miss android system and really go back to one.
I have switched from huawei p30 lite (lcd display) to the Samsung s22 ultra and after using the Samsung for few months i started to feel the display is not comfortable on the Samsung phone unlike the huawei And now after watching this video i finally understand why😢
Last year I had returned my IQOO Z7 pro because of the headaches caused due to PWM. Since then life is like hell, I'm unable to use LCD display phones too after using them for long time, don't know the reason for it. Maybe I have become extra sensitive to even slight flickering. I have purchased Moto Edge 50 pro now after looking at its pwm frequency and DC dimming options. Lets see how my experience goes with it🤞🤞
Hello, my previous phone was Galaxy A71 and I had it for 4 years and the PWM rate was 240Hz and I had no problem with it. I bought Galaxy A55 for a while now, which also has a rate of 240Hz, but I have a little problem with it, eye strain and a little headache. What do you think is the reason? what is the solution
I bought an OLED Steam Deck and instantly on my first gaming session I got headaches and felt dizzy. I had to sell it at a loss. I use my iPhone 12 a lot at night and I do not get the symptoms. I also got this before with certain CRT monitors back in the day.
What a the current best smartphones with a good pwm rate? Should I sell my s24 ultra just because of that? The s24 ultra has 480 pwm rate. Is this very bad?
If it does affect you badly then you might have no option to sell it depending on your presence. But you have to move to chinese manufacturers or nothing branded phones. But then overall they are no where as good as Samsung Google or iphones in other areas
@XTechByJoinTheAvid Thank you very much for the answer. 🙂👍 I would not say that it effects me negatively. But also if it does not effect me negatively isn't it bad for my eyes? That is what I worry about!
I have Galaxy S7 and Galaxy A15. They don't give a fatigue to my eyes after using it for a long period. But my new Galaxy S23 hurts my eyes so badly after using for just 10 minutes. I checked S7 vs S23. They used different default pwm frequency for same brighness level. Galaxy S7 used lower PWM than Galaxy S23. Is there any relation between their new Dynamic amoled 2x (S23) with eyes fatigue issue? My galaxy s7 and A15, they both using super amoled, works fine for my eyes. This is so annoying. Expensive phone but it harms your eyes.
Bought an Redmi Note 13 Pro 5G. Can't use it, after a few seconds my eyes are in absolute pain. The sad thing is, I had no Problems with my Mi 9T Pro :(
@@XTechByJoinTheAvid Xiaomi 14 (but not T Pro and Ultra) has the Anti-Flicker mode like my 9T Pro. But the Xiaomi 14 cost 1000 bucks, and this is out of my pocket... 😐
iPhone 15 plus pwm - 60 hz 15 pwm - 306 hz 15 pro pwm - 242 hz 15 pro max - 242 hz this is according to notebookcheck I'm thinking of going back from iPhone 13 mini to iPhone 11 but I love my 13 mini so much. although I have no issues with its screen during the day. but at night something feels off at low brightness. like I don't get headaches but I find it annoying / unable to focus comfortably at low brightness.
Honor magic 6pro is good in market having around 4300 pwm,after using s24u, i got much headache and sleep distrubance so,i recently brought it, i need to test how it is helping me
@@viveksabharwal9027 Hi vivek, Definitely worth to buy if you are looking for eye comfort, I am so satisfied with the phone performance wise and eye health wise
@VYM, have you tried enabling the circadian display and setting the night sight to automatic display? I recently conducted a personal experiment, using the Samsung S24U for 15 days and the Honor Magics 6 Pro for another 15 days. Based on my observations, when using the Samsung device between 8:30 PM and 10:30 PM, I experienced difficulty falling asleep after turning it off. My eyes felt strained and dry, and it took me approximately two hours to finally get some rest. However, after switching to the Honor Magic 6 Pro, I noticed a significant improvement in my sleep quality. I was able to fall asleep within 15 to 30 minutes, and sometimes even while using the device itself. In my opinion, this particular device seems to have a positive impact on sleep compared to others. If you prefer not to use a smartphone, I would recommend considering their tablets as a secondary option.
@@Hemanth_321 tried everything. All options. Only Honor 200 and Iqoo Z9 felt little bit better, but still not IPS. So I'll be stuck with my Poco x3 pro till the next IPS display phone is released.
I use a samsung x cover 7 with lcd screen. But it still makes me feel a big sick. Like i havd been reading in a car. And my head starts hurting afther a while. Do you think you Can tell why that could happen with a lcd screen please?
It's maybe due to blue light emitting issues and higher brightness.. usually any smart devices will hurt if you use it in a long session. But BAD PWM is the worst of all in OLED
Yes your correct im currently using poco x4 gt and iphone 11 which is IPS LCD, im also had headache with pwm oled phones, hopefully they can fix this soon
I just returned a pixel 6 due to this and a LG oled tv a few years ago. I dont see noticeable flicker i just get eyestrain and pressure in my frontal lobe I have an accute sensitivity, but not to all for example im fine with the Samsung A51, Pixel 4 XL and Note 10+ using eye comfort setting. Anyway would love to learn a fix
Hello. things turned out quite interesting for me. almost every new phone gives me a headache and I can't sleep for days... The point is that I have the z fold 5, which many people say is very bad for pwm sensors. I have no problems with the z fold 5 phone... but now comes the interesting part, because I bought the Honor magic v2 phone, which, if I say correctly, uses 3850 pwm, but is completely Oled... well, after 15 minutes from this phone, I have a headache for 3 days... so I think this pwm thing means nothing... especially this blue light /eye care protection... Maybe just for me....but sadly not worked for me the Oled screen...same as the tablet s9 ultra....or s22 ultra....
Yes! PWM is Very Bad For Eyes, I used iPhone 13 Just 2 months, i got very eye strain, Headache also, i suddenly sell my iphone and Bought Realme 11 pro plus, 2160 Hz Now safe for my Eyes.. I like Apple but this problem.. Good bye to Apple and Many OLED Screen Androids
Look the PWM works at the hardware level.. where they use a technique through software to change frequency of the LEDs on and off cycle.. extra dim is a software filter on top of the UI
