Usable Smartphones?

hansennn

KM Thank you very much for your reply,actually i have not buy OP3 and after googling it,it use a cyanogen os right ?,i have asus zenfone from my company i think i want to test it to install cyanognen and use screen protector from ensente.because op3 for me is not cheap and if i buy it and failed,it's hard to sell it again in my country for this brand.Or can you give me list other than op3 that can you use without headache even an old type smartphone is alright for me because i can search in here for second hand device.and want to ask how to disable dithering in android ?in windows we just use standard vga driver but in android there is no option like that

KM

hansennn OK, I first thought you had an OP3 and wanted to know my settings for it. I think the main reason the OP3 works for me is the type of display it has. I believe they have a return policy so you could send back the device within like 2 weeks. It runs on "OxygenOS", a custom Android version made by OnePlus. CyanogenMod runs on it, too. But currently they are in the process of switching to "LineageOS" so at the moment there are no official downloads available anymore.

I have not found any other device that works that great for me. The closest is an old iPhone 4 which is not perfect but still very usable for me. But: There are different versions of the iPhone 4, and you won't know if you have a "good version" until you try it. And: It is totally unusable if you upgrade it to iOS 7. I think the chances of finding an iPhone 4 that has a good screen AND is still running iOS 6 are very, very low nowadays.

Others here in the thread had luck with an HTC One M8. But it's eerily similar to the iPhone 4: There are good and bad versions of the display (no way to know it before trying) and if you upgrade it to Android Marshmallow it might cause greater eye strain...

KM Would be very interesting to understand how a new operating system version can cause eye strain. (I emphasize that I'm not saying it isn't possible - could be my case as well, as when my Z2 was Lollipop, I did not get any eye strain but now it seems I do.) But the science behind it would be good to know. Interesting that the developers are so deeply hidden that nobody has any contact to anyone who knows about what the developers actually have done in the new versions. It should be as easy as some developer bumping into this kind of discussions and pointing out "oh yeah, we implemented temporal dithering slightly differently in Marshmallow"

KM i think i will find htc m8 second hand so i can test it before,in my country it's almost imposibble to buy something from outside of my country so if i want some device i must buy from local shop that doesnt have return policy but sell it again with price form almost half of new price even if i just buy it for one day.have you test using screen protecor suggest from ensente ?do you feel headache or migraine after eyestrain ? actually i don't have any eyestrain(if it mean red eyes or tire eyes) or teary eyes) just headache and become migraine if using device for long time and if ican choose i will choose eyestrain over headache because headache migraine is such a pain for long one day.Recently i have my asus zenphone got rooted and install pimp my rom,i disable surface dithering option but it still make me headache,some says in other forum that pimp my rom just fake app or placebo effect,have you using pimp my rom ?

Maxx I'm pretty sure that the changes that are happening are overlay/composition related, which we affectionately refer to as "compositing". Basically how the display builds output for the screen has changed. Maybe it introduces some kind of flicker. Maybe it pushes the display harder. Maybe it changed the color output slightly. Whichever it is, it's well noted in some versions of iOS, as well as Marshmallow on the HTC and now even Windows 10 Anniversary.

KM

hansennn I did not test any special screen protectors apart from normal clear ones which probably don't change anything at all. I tested supposedly 100% blue light blocking glasses recently, but they didn't help. I also get headaches over time, when I continue to use problematic devices. First eye strain, later small headaches.

On my (bad) HTC One M8 I disabled surface dithering. Not with an app like pimp my ROM but manually in Android's "build.prop" file. Didn't help at all. It was one of the most terrible devices I ever used.

babakkardan i get eye stain from LG G2 after a few minutes of use.

tomek

I got G2 and I use it with Blulight Filter and only this work form me, others from google store don't: https://play.google.com/store/apps/details?id=jp.ne.hardyinfinity.bluelightfilter.free , Try this with first green filter at 30% it work for me. Without filter strain after few minutes - with whole day nothing.

hansennn There is only one kind of Skinomi screen protector. I have used them for both the MotoG and the Blu R1 HD. Without the screen protectors I get eye strain within seconds of using the device, with the Skinomi on I can stare at them for hours with zero effect. Give it a try, it only costs like $10 or so off Amazon

Because the screen protector works for me I am not convinced that PWN or dithering has anything to do with the strain I am experiencing

hansennn

ensete today I try skinomi with my ZenFone ASUS but still make me headache but I think not so bad as usual,I want to ask in the skinomi box there is 2 screen protector,are you use both (double protector) ?because I use only one protector and I want to ask you use how many brightness level right now ?or you use blue filter application ?I saw your last post about your phone moto g after got update marshmallow,you have eyestrain,even after use skinomi with it you still got eyestrain?or maybe there's some setting ?sorry if I annoying always ask the same question,because I,m on despair

ensete

hansennn My box only had one protector. It's a rubbery kind of film.

As the time of my Moto G I was not using a Skinomi, I was using a Techarmor, and yes, the update to Marshmellow gave me eye strain even with that screen protector on.

My current phone has a Skinomi on it and I have blocked the Marshmellow update, so I cannot comment in whther or not it will help

hansennn

ensete what is your android is in your current phone ? And you use brightness level on your current phone ?

Gurm

I simply don't know what I will do when my HTC One m8 dies, since Marshmallow is unusable for me under any circumstances.

KM

Gurm If it dies, try a OnePlus 3 - I recently upgraded to Nougat 7.0, and it's still the same.

Gurm

KM Good to know. Thanks.

hansennn

KM excuse me i want to ask if this type oneplus 3 https://www.tokopedia.com/nyoto/oneplus-3-black-a3003-bekas/talk is same with your oneplus 3 type ?

KM

hansennn My model type says A3003, too. People say the successor, the OnePlus 3T, has the same display.

hansennn

KM I think i will get the same type with yours A3003,even it's second hand and it's still expensive for me and it's cost almost $300 for a second hand phone.i don't wannt to take risk to get oneplus 3T.Actually I don't care about spec or android os or screen size or etc,i just want to have a smartphone that i can use without headache.From your past post about oneplus 3,you just change britghness to make this phone usable right ?
(OnePlus 3 Usable when brightness >= 68/255 (OxygenOS 3.2x) or >=65 (CyanogenMod 13)
60 Hz low percentage flicker (lower than incandescent bulbs: https://ledstrain.org/d/21-usable-smartphones/169)
Not usable at lower brightness: 240 Hz PWM flicker
Source: Me in "Usable Smartphones" thread, https://ledstrain.org/d/21-usable-smartphones/144
I already read all of your post about oneplus 3 and there is no setting about dithering or blue filter application or setting at developer option etc

KM

hansennn Yes, I Just disable auto brightness and set the brightness manually. No developer settings. Blue light filters and Night Mode actually introduce eye strain for me.
I hope it works for you, too. I just wonder why OnePlus won't ship to your country, are you sure about that? I'd but directly on oneplus.net to be able to make use of their return policy.

hansennn

KM Actually i never buy something online from outside my country.I don't have paypal or something like that.and i already ask my friend that even if we want to buy something from outside of my country,the price will be 2-3 times of original price because of tax etc and it can take some months for arrival and the return policy only 15 days.I want to search second hand on the shop so i can test it before buy it but i never found it because it's rare and quite expensive for brand that not too commercial in my country like samsung apple etc so not many people buy it in my country or i want to install cyanogen for my current asus zenphone 2,i think it have same os with oneplus3.By the way is there in this forum beside you that can use oneplus 3 without headache ?

KM

hansennn I think nobody else here has tried it yet. Would be great if it worked for everyone. But of course, aside from the PWM part I can't really say why it's usable for me. There's the chance it only works for me. So yeah, there will be a risk in buying it.
