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

      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.

          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 ?

              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.

                  It's available at Amazon via Prime, which means it can be tried and returned, at least in countries that have proper Amazon coverage. (No offense intended to those of you who live in Lower Eastern Slambovia!)

                    KM Yes it's very difficult to know what smartphone that i can use,unlike on computer where i know i can use all computer that out before 2010/2011 because of intel driver,if only we can use "standart vga driver option" on smartphone.

                      Gurm honestly i am not yet decide to buy it because it's quite expensive for me,i am already ask my friend who know about amazon and he say after tax etc the price become 2 times origiinal ,it think it's not about the hardware (smartphone) but it's software (Android OS) if only we know what cause of headache on smarthphone,like on computer because of intel driver.

                        it think it's not about the hardware (smartphone) but it's software (Android OS)

                        It can be either or a combination of both

                          ensete I think it's about software for me because if i playing a game (nds and psp emulator) on the smartphone i don't feel headache but if i am browsing,chatting,checking email,watching video on the same smartphone with same setting,i feel headache.Maybe because GPU,If only there is a option to always activate gpu.Have you try to playing a game on your defect smartphone ?If you haven't,i hope you can try it for 5-10 minute because it's click with your symptom,i have read your past post about you using a same monitor on PC but using different software (driver) make you eyestrain.And maybe everyone in here can try to playing a game too on the smartphone,If everyone have the same symptom with me than we can find what cause of this problem and can make a software or application on android that can eliminate this problem.

                              hansennn If everyone have the same symptom with me than we can find what cause of this problem and can make a software or application on android that can eliminate this problem.

                              Honestly I think that's a fools errand. It could be any number of issues and each thing could effect any individual differently.

                              My strategy has always been try devices until I find one that works, when I do buy 3 of them, and never ever upgrade.

                                I can't tolerate my iPhone 6s anymore. I have made good progress in my eye health by avoiding problematic screens, and the iPhone 6s is the worst screen I own, giving strain within a few seconds. Now I only use it to answer phone calls. No texts or emails. It's a big problem. Is the OnePlus 3 my best bet ATM? I know there is no sure answer but what should I try next? I'm pretty desperate and willing to sink some cash in to resolve this issue. It's insane not being able to use a phone when I'm trying to conduct business. Thanks.

                                  degen Have your eyes been really strained recently, like through over-reading? I know that even your garden-variety eye strain will often come with a bit more photophobia than usual. I wonder if you're more sensitive to the backlight after.

                                  Have you tried NightShift on your 6S+, keeping it on all the time, and brightness at 0%? It's helped me with my iPhone 6S+

                                    I am using the lowest brightness and Nightshift at warmest setting. Still hurts bad. This phone doesn't trigger garden-variety eye strain like my good screens do. It's awful and has been there since I got the phone, although I tried to deny it because it's the best phone I've ever owned otherwise. I came from an HTC One m8 which was comfy to use and I seriously regret trading it in. With this condition I've learned that if you have a good working setup, don't change anything unless you absolutely have to!

                                    degen, have you tried the skinomi matte screen protector recommended by... uh... I forget who in a different thread? You and I have similar issues, and I find that the screen protectors - at least on iPhones - do help quite a bit. Not enough for me to trade in my One m8 but a bit.

                                      degen Have you tried adjusting the white point and reducing motion? It made a difference for me (not game-changing but more comfortable than default).

                                        Gurm That was me 🙂

                                        I can say for iPads at least, the matte, anti fingerprint, anti glare Techarmor screen protectors completely, 100% cured the eye strain I get from them. I have only used Skinomi's on Android devices.

                                        I would try the Techarmor protector for the iPhone

                                            Just wanted to add I tried LineageOS (Jan-31-17 or slightly newer) for some days on the OnePlus 3, and it is currently not usable for me. Burning eyes after prolonged usage. I tried to search for the reason and found out that the color profile is reset every reboot to a color-altering profile. Must be a bug.

                                            This further confirms my observations about color profiles, which I mentioned in an earlier post. They introduce eye strain when they're active.

                                              I have now Oneplus 3T (Oxygen 4.0.3) since last Wednesday it's fast and great phone but I will return it.
                                              3T is way better then any iPhone and it seems to be like LG G2 without bluelight filter, but even with my filter which work wit my LG G2 - 3T is making eye strain. Maybe in log therm it should be better but I have to send it back in 15 days.
                                              I haven't tried CM13 or other software to not have problems with return. Changing colour temperature, night mode or sRGB is making me much bigger eye pain then default colour profile.
                                              So for now I will stay with my old G2 with bluelight filter, this I can use whole day without strain.

                                                tomek Don't use any blue light filter apps. Like you noticed with sRGB mode and those other color settings, it seems that any app that changes colors, including "blue light filters", will cause eye strain.
                                                By the way, did you make sure to set the brightness to at least 68/255 (to prevent PWM)?
                                                Those two things are absolutely necessary. Not using any color apps, and making sure brightness is >= 68.
                                                And only use Chrome as web browser.

                                                    This lines up with my ICC cure on my monitor. It seems color profies have a lot to do with whatever we are experiencing
