Usable Smartphones?

richiesuk

Hi all,

My story is the following:

My eyes generally light sensitive and in the past I could easily notice if a crt monitor was run by 60Hz, ppl thought I am a weirdo

85-100Hz was ok for me

Since using mobiles I had no issues with LCD. Screens.

I have a huawei p20pro which has 238 pwm, and it makesy eyes tired by end of the day a bit.l and also it's an ancient device and wanted to upgrade.

I had no issues with iPhone 11 iPhone 12 mini btw.

My wife bought a iphone 14pro and after 5 salec I felt dizzy and my eyes were really strange, never felt this before.

Also I had honor magic 50 pro for 2 hrs and I had the same feeling. Packed and sent it back straight away. Never mind they super eye friendly screen, 2160hz pwm, etc . Didn't work for me. Could it be because LTPO?

Thanks

richiesuk try an ips screen.

A second hand Mate 20 Is perfect.

richiesuk No, you are not weird!
Humans are able to perceive CRT flicker (and flicker in general, be it single strobe from CRT's or multi strobe such as PWM dimming) very easily, especially till 75hz, which is the cutoff.
What you've experienced on the phones you've mentioned is called PWM, which is a form of strobing used to modulate brightness in smartphones.
The only way to avoid this is to opt for a modern LCD smartphone (the list above by Vividblu is quite decent), as all OLEDs inherently suffer from this design flaw. This is not fixable through a software update. The panel itself implements how brightness dimming is done, so it'll take a few years till OLED becomes usable for people more sensitive to PWM.

Hello Richiesuk,

i have exactly the same issue. In my experience until 2020 I only had problems with my eyes. From 2020 my eye problem disappeared and I got headaches/dizziness from screens. I have tested 20+ screens, also some before 2020…and I dont believe the PWM theory. I think the manufacturers installed a "trick" by software to compete on the most "in your face screen". Most vivid colors, etc.

I think there is no other option to wait until a new wave of phones comes out, and maybe they are ok, for which reason it may be.

Aquila unfortunately I want something newer. Tonhave good speed and camera too

Hello.

And none of the mobiles with DC dimming feature would be ok/helpful?

Thinking to try xiaomi 13.

Thanks

richiesuk I've tried amoleds with DC dimming.

Didn't make much of a difference for me.

I've had good luck with Sony phones the colors on these phones are very natural, I used an Xperia XZ1 which has no PWM after 25% brightness and at 24% brightness and below the PWM is 2358Hz which i found tolerable. I upgraded to an Xperia 1 IV in September 2022 which has an OLED screen and 500hz PWM but doesnt bother me. I cant use Xiaomi phones their color profiles really are just bad on my eyes and i never liked the way the colors looked on those phones either.

Abeabe Sorry to hear!

Is the dizziness severe? Does it happen instantly or after prolonged use?

Abeabe

Vividblu99 Its a mild dizziness but it gets stronger and stronger and by the end of the day if I used too much this Realme x50 5g, I feel super mega dizzy.

I've been playing around with the smallest width settings again in developer mode. If I set this between 475 - 500, the text and icons/images all shrink, but also become a lot more clearer and comfy.

I've tried this on a number of lcd phones, and it seems to be helping me further. Might not work for everyone, especially if you have hyperopia. But it's worth a try.

I always assumed smaller text/icons would cause more strain. This doesn't' seem to be the case with me, surprisingly.

Hi, how about this: Honor Magic 5 Lite 5G

Anyone tried this?

richiesuk

Hi all,

New xiaomi with IPS screen.

Vividblu99

richiesuk Hopefully this will be rebranded under Poco, worldwide! Although it's unlikely to be released in the UK ;(

RulerofNothing

richiesuk Yes very interesting because it is with the Dimensity 8200-Ultra, DDR5 RAM and UFS 3.1 way more powerful than my Realme 9 Pro. When it arrives like his predecessor as Poco X4 GT here i will try it. But with the X4 GT i had no luck and there Xiaomi was also speaking of a LCD display with DC Dimming.

For Honor Magic 5 Lite 5G, from:

https://www.notebookcheck.net/Honor-Magic5-Lite-5G-Review-Thin-smartphone-with-thick-battery.718950.0.html

"Due to its high-frequency PWM dimming at 1,920 Hz, OLED flickering as such is actually not a problem — this is the same technology used in the Magic5 Pro. Nevertheless, we measured a constant frequency of 60 Hz with the oscilloscope, which could be a burn-in protection."

What do you think about it?

Anyone care to share their thoughts on these videos?

@Dok123

Watch these video's to get an example & idea of the PWM on the Magic5 Lite 5G.

Thank you, so it is not so good.

I was considering Motorola G73 5G, but I'm not sure for the low brightness level of the display.

I was also considering to buy Realme 9 5G, waiting for the release of a better usable smartphone.

Vividblu99

Dok123 I tried the G73 5G. Couldn't tolerate the display. Instant eye strain.

Realme 9 5G is a cheap & safe bet. But yes, it's underpowered, but it'll do a decent job for casual browsing/surfing the net, social media/youtube etc.

Vividblu99

Abeabe That is definitely not a good sign! Have you got any other handsets you can use instead?

It seems the x50 5g is definitely not the phone for you.
