Usable Smartphones?

K-Moss

Anyone tried a Nokia 3.1? It has no PWM at any brightness levels, and can be obtained cheaply unlocked. How about the Moto G9? It also has no PWM.

I've checked the contrast ratios for the Nokia 3.1 and Moto G9 plus and the Nokia is over 2000:1 and in my opinion it's too high. The Moto G9 plus is around 600:1. I have an LG monitor which is 600:1 and it's really comfortable to use. The Moto G9 play is well over 2000:1 and I wouldnt recommend it but that's just my opinion. Hope whichever phone you choose K-moss is good for you.

I find that any phone with under 1000:1 contrast ratio and pwm free works for me.

I currently use the Honor 20 and it's great. Just use notebookcheck website for reviews as they measure pwm and contrast ratio.

Just make sure to go into accessibility features/accessibility/ turn off advanced visual effects that adds shadow and blur

This shows the Moto E6 no PWM.

This shows the Nokia 3.1 no PWM.

As you can see, though both are no PWM, the Nokia looks like it has a much clearer display signal. Any thoughts on that being noticeable in everyday use?

K-Moss

Is the difference because they are using a different time scale? It looks like that may be what is causing the difference in visual appearance. Time on the bottom says 20.00us and on the top says 5.000ms. 20.0V on the bottom and 500mV on the top.

Any thoughts?

K-Moss You can see the scope view of the first image is much more zoomed in (time scale) compared to the second.

This is a all a science and not an exact process.

While everyone is different I personally had issues with the iphone SE2, it would give me eye pain and headache almost immediately on pretty much all settings.

I get the same symptoms with the Iphone XR.

Neither of them have PWM, I used reduce white point on each of them but symptoms still persisted.

I am able to use an Iphone 8 / 8 plus / Ipad 2018 without issue ONLY if I enable reduce whitepoint to the first setting, otherwise I get similar eye strain / headache issues. Without the reduce white point its like all the colours are still too bright even with a low backlight.

Problem SE2 and XR even with the 'lower' brightness colours visible on the screen when using reduce white point still caused the symptoms.

Thank you - interesting XR didn't work out. iPhone 8 would work but battery option over time == almost useless

Iphone 11 with reduced whitepoint to 55%, reduced transparency and increased contrast works for me. (It has 0 PWM also).

I used the Moto G 5G which has pretty much the same screen, mine had PWM when it should not. Even at full brightness I could not use it and I could not detect PWM with my other camera at full brightness, I did make a posting about it on here somewhere.

Even devices that dont have PWM can cause issues. They must flicker in other ways.

More likely that flicker is not the trigger

Is there a confirmed list of phones that are suitable then? It seems even in Wiki we don't have a definitive list.

I'm looking to buy a like-new Honor 8X. Anyone have any problems with this unit?

DAVEGEO

Just checked the contrast and it's 880:1 and black level over 0.50 so I reckon it will be very good and comfortable. Maybe have a look at one in a phone shop if possible. I have no problems with my honour 20 and had it for a couple of years now

Can you confirm if the Honor 8X is still compatible with Google Play?

DAVEGEO

K-Moss

Judging by some of the reviews I've seen it isnt compatible out of the box but you can install with a workaround but I wouldn't be happy with that. As an alternative I've bought oppo A72 phones for my in laws and they are a great phone with contrast at 913:1 and black level 0.55. I've seen them after I set them up and the screen is nice and comfortable and large. Also has Google play as standard.

Have a look

Any recs for phones that aren't huge? Anything over 5.5 inches feels to big to me but everything out there seems to be 6.5 inches or more. I don't want to hold a roofing tile up to the side of my face

In my opinion, you don't want to hold any cell phone to your head. I always plug in ear pieces with a mic or else use a bluetooth device. Given that, the bigger size of 6.5" and larger helps productivity when using the phone as a mini computer.

I don't use headphones or airpods or anything. 6.5 inches, to me at least is to large to hold comfortably in one hand or fit in a pocket.

Although it is a very limited mobile phone compared to today's alternatives I can use OPPO A52 with full ease.

Dropped using several phones including Apple, Sony, LG etc. models. Now hopefully I may find a phone with the same screen in better specs.

Leaving this info here since it may help someone as well.

I dropped and cracked the screen.

So I bought a new A52 one from another vendor. Unfortunately, apparently they don't have same type of panels. Brand new one is not comfortable to use at all. There is this new type of LCD panel which is more smooth, yellowish and buttery. Those ones cause problems as well as OLEDs. I have two devices same brand same model same year production holding completely different screen panels.

New tech screens getting more frustrating and expensive for me.
