randomboolean You say that PWM does not affect you because you have an old Acer which has flicker and the Galaxy S4 which had an OLED screen and thus PWM affected you. Have you figured out what does affect you?

      ryans No, sorry. I am so confused now as I have "resurrected" my old Acer from 2011 (I installed windows 8 vs windows 10 and installed very old drivers) and tried it for a couple of hours and unfortunately it also gives me blurry vision... Of course no brain aches, no migraines, no eye pain, but still if compared to my external CCFL monitor, this one is not good. It did not for over 5 years 🙂 So I think I damaged my eyes for good and now even good enough monitors give me strain. So I am still testing both with phones and laptops.

      Tomorrow I am receiving Oneplus X 16GB. I hope it will be as good as my Lumia 930 (both have amoled displays). Unfortunatelly Oneplus One (with IPS screen) is not too good for my eyes. With Android 5 gives me blurry vision after 20-30 mins.

        So OnePlus X gives me terrible headache and eye strain (worse than Oneplus ONE with IPS screen). I installed original Android 5.1.1, Twilight app, set brightness to 100% and dimmed the display with the app. The specifications of the phone are the same as on Lumia 930, so I assume there is something in screen that gives eye strain. I am not sure what else I could try. These phones are already outdated and they are unusable, so going "back" in time would mean buying only used laggy, unusable phones.

        So we are stuck on 2013-2014 without the solution for the future. 🙂 I think eventually we will need to go back to basics and buy Nokia 3310 (2017 edition). One of my clients are still using old phones, and when asked how do you check emails and everything he says - I don't, I just phone everybody, like on good old days. He is over 60 years old so he is used to it. Not a solution, but more of a bahaviour change. For example amputees cannot walk or write, we cannot look at the new screens and use new devices.

          randomboolean Those brightness apps that dim the screen colors by using overlay permissions make my eyes hurt, too. They probably add one extra layer of composition. Maybe it's the same thing that makes color profiles unusable for me on these devices.

              I would agree about trying to avoid screens whenever possible however for most office workers this isn't a choice. Many employers are now giving work phones/tablets to staff as well.

              Most office hardware is (thankfully) 5+ years behind so it's not an issue.... yet.

              However once smartphones/W10 machines/LED becomes compulsory (because all the old equipment has died) this does pose a real issue, unfortunately it seems to a very small minority of users.

              I'm still OK with my iPhone 6S, I don't use it for hours on end but it is far more comfortable than any modern PC monitor/GPU.

                  diop I also use an iPhone 6S+, and it's been the most tolerable cell phone I have used since my old iPhone 3GS

                    KM Hmm did not know that these apps might do more harm than help us. I will try to root the phone and install f.lux and change to other drivers. Let's see if that helps. But this phone is hard to flash and root, have already bricked it for 2 times...

                    diop Exactly my thoughts. Thats' why I am thinking buying as many "outdated but new unused" devices(still possible to find unused 2014 phones, etc.) as possible and future proof ourselves. The technologies does not change so rapidly, so we might wait for new eye strain free devices for over decade.. And this is really bugging me as I am a IT project manager and I am almost unable to do my daily duties due to this problem. It is easier for programmers as they do not have so many meetings with so many different clients and devices. Sounds like I need to change careers 🙂

                    It's really strange how differently people are affected as iphone 6s is unusable for me, but many of you huys report it is good for you. What OS version are you using? I think there might be different manufacturers of screens so it might be you got a "good screen".

                          Maybe it's enough to stay out of the PWM range. Set brightness to roughly 50% and PWM should be off. I think the exact brightness value for the OnePlus X where PWM turned off was 80 (out of 255) or slightly higher. Don't try too many things at once. I'd stay away from any apps.

                          Most probably. After having read on the Apple forum's Macbook Pro eyestrain thread that some iPhone 4 are usable while others are bad, I kept buying iPhone 4 and 4s until I found ones with usable screens. The difference was like night and day and still is.

                              The Nokia 3 and 5, Moto G5 and Moto E4 were all causing me eye strain. Finally I found a phone that doesn't hurt my eyes not even with low brightness set.
                              It is the Samsung Galaxy J3 Duos (2017)
                              Hopefully this can help other people who are looking for a phone that's comfortable on the eyes. Good luck everyone !

                                randomboolean I received a brand new iPhone 6S+ less than a month ago, after Apple accidentally broke the battery compartment while attempting a battery replacement. The new phone works just as well as the old phone (with longer battery life of course!) I did notice some small unrelated alternations though. The sound and even feeling of the vibrate feature is different than my last 6S+

                                  michiel The Samsung J3 uses a Samsung chip instead of the Snapdragon. Since it's a Samsung chip, the display is probably very closely matched, and probably has stellar driver support in the stock ROM. The chip is an Exynos 7570. It's also got a 720p screen.

                                  Interestingly, the S8 also uses an Exynos chipset, but it uses the 8895 and has a 4k screen...

                                      Also it does not use Amoled. It has a PLS TFT LCD display. I am also testing and it seems I can use it. I was lead to this after using Samsung Galaxy Tab E which does not use Amoled as well and it is fine for my eyes.

                                          Peter Definitely going to try it. But it comes with Android 7,0. Doesn't it bug you at all? By the way where are you from? We already noticed that screens differ per country/region, it would be nice to buy it from your country.

                                              I am testing a friend's J3 which is is bought sometime ago from Amazon.co.uk (UK resident). I am still testing it, when i visit her and play with the phone for an hour or so, it does not bother me. Can i check something within the phone that it would be useful to share?

                                                  Peter Thanks, I just received the phone and will let you know how does it go for me. If it gives me eye strain it would be nice to compare the android, build, kernel, etc. versions between my device and yours to check for differences. If it gives me eye strain I will return it.

                                                    I wish someone would make a phone with decent specs that uses one of these less offensive chipsets and screens. My dad has the J3, it's an ok phone but certainly less powerful than I'd like. I also briefly used a Samsung Galaxy Prime and that was also fine but again the chipset was garbage.

                                                    There was a trend of people making stripped-down phones, for example HTC had the mini for a while which was a 720p screen with a decent processor and less storage (but a MicroSD slot remedies that).

                                                    randomboolean Android is version 7. 'Less' means that I get strain after about 30 minutes, but no migraines, just that the eyes get tired. Significantly there are no migrainous symptoms like nausea, etc. for about that much time. On increasing the brightness to say 20%, mild symptoms do appear after about 10-15 minutes, though not as severe as they do with other phones so far. It's hence possible to get some quick work done.

                                                        Devotee I tested the phone yesterday and get the same feelings. No headaches, but still blurry vision after 15-30 mins. Might be a good enough option just for answering/calling people, reading quick mail, but no prolonged use(youtube, email writing,etc.). I will still return the phone as they shipped the wrong color and will think about this for couple of days.

                                                          Did anybody tried Sony Z5. There was stated here that Z2, Z3 and Z3+ are good enough for our eyes, and XZ is terrible. The Z5 is produced after Z3+ and before XZ. As far as I understand all of them have the same matrix. But Z5 has fingerprint scanner and I would prefer this model. Is Z5 still OK for us?
