Usable Smartphones?

s_u_ I am still using Xperia XZ1 and have no problems at all.

Is this the 4k phone mentioned by @tfouto ?

What is the Max, the bigger screen version of the XS, which was called Plus in earlier models? Have you tried the XS standard size? For reasons which are unknown to me, overall I noticed the larger screens give me considerably more eyestrain.

That should be bigger version of XZ1 which is XZ Premium. I belive both of those devices use same type of screens.

I have also tried X and had similar problems. But, yes Max was the worst. However I believe the problem is not PWM. I feel like there is a problem with the light those newer devices emitting. My eyes and head hate that creamy, smooth bright light coming from those screens.

PWM is absolutely 100% not the problem for me. It might make a bad display worse, but it isn't the problem - I can spent literally days staring at heavily-PWM'ed screens with no issues.

Buy a OnePlus 3 with Paranoid Android 7.3.1. For whatever reason it does not have the software eye strain issue.

KM I so wish OnePlus phones worked on Verizon in USA.

KM Does the OnePlus 3 use PWM? Are there any special settings that need to be applied to avoid eye strain? How long will that ROM be supported before an upgrade is required?

I am considering buying this phone. Why does not it work on a certain carrier? Is it a matter of bandwidth? I thought that depended only on the geographical area! Thanks!

KM

diop PWM only below brightness 65 out of 255. Special settings: set brightness to 65 or higher, don't touch color profiles or night mode. Standard profile out of the box is OK. No support anymore, final ROM version. At least the KRACK WPA2 vulnerability is fixed. It officially still gets updates from OnePlus, so there's hope they'll fix the eye strain issue in the future, though I wouldn't bet on it. Shame that it doesn't work with Verizon.

KM Maybe you already answered this question. Have you tested Paranoid Android on more recent One Plus phones or other brands? Eventually, does it still run smooth on your eyes, or the hardware/software combination makes a difference? Thanks.

OnePlus 7 announced with DC dimming as a option.

No idea about the "software" eyestrain issue.

JTL If it is genuinely PWM-free with that feature enabled then that certainly is one link in the chain removed.

How are OLED displays on the bluelight spectrum as opposed to LED?

Will anyone here be picking one up to test?

Gurm

AGI you can generally make calls on any network, but the OnePlus devices do not support enough of Verizon's LTE bands to have full functionality and activate as a Verizon phone.

The only brand-new OnePlus 3 I found on eBay costs about USD 1500 🙈

AGI I have installed it on a OnePlus X, but that's even older. Didn't use it for too long, not thoroughly tested, it's just a backup device.

We tested this mode more in depth and were still able to identify flickering that remained at a quite constant level of around 60 Hz.

Seems like a technology requirement. The PWM-free Galaxy 7 Edge Kernel has it, too. So they probably just do what @Wootever once did, a software change.

Noteobokcheck or someone else with an oscilloscope should test 🙂

Maybe I should write them an email.

Taken from NotebookCheck review of the Xiaomi Black Shark 2 with DC dimming:

Due to the OLED display, Pulse-Width-Modulation is used for brightness control. As soon as the display is set below maximum brightness, the screen flickers at a frequency between 81 and 245 Hz. A range that could be bothersome to sensitive users. Xiaomi came up with something in this regard, namely an option that is quite hidden within the settings and is called "AMOLED low brightness flashing protection". This can be found within the display settings, in the sub-menu corresponding to color reproduction. This option should reduce flickering at lower brightness levels. We tested this mode more in depth and were still able to identify flickering that remained at a quite constant level of around 60 Hz. The amplitude becomes flatter with the increase of brightness. It's feasible to think that this mode will lead to fewer complaints due to its more even flickering, albeit at a lower frequency. The response time of the AMOLED display isn't impacted in a negative way by this.

Hey, one thought. My Samsung Galaxy on5 stopped working in February. I tried to resurrect it via Odin without success (I got recommendations from a forum of Samsung nerds, so I quite sure I did all that could be done). Basically, the phone turns on, displays the Samsung and model number logo - sometimes it has gone a bit further and showed the T-Mobile carrier logo (phone is unlocked though) - and gets stuck. Any chance to install Paranoid Android on it??? I had no problem at all with this phone till an update on May 2018. I would love to test a different OS. Anyhow, I have nothing to lose. What do you reckon?

AGI

@KM Looks like the answer is no. Only some brand/models allow switching OS?

AGI That ROM was created only for a few select devices, unlike major ROMs like LineageOS. But the reason it works so well is probably simple: I think unlike others the Paranoid devs simply didn't copy the display changes (perhaps the default color profile) OnePlus had done to their public source code at some point (transition to Android 7.1). So it is doubtful the ROM would help with other devices. Worth a try for sure, but yes, your Samsung is not listed.

'Paranoid Android is a custom ROM aiming to extend the system, working on enhancing the already existing beauty of Android and following the same design philosophies that were set forward by Google for Android Open Source Project.'

I understand they have Google's "approval". Is that why installing Paranoid Android does not invalidate the warranty? At least for a listed device?

Have you ever mentioned to them your issues with Android and asked why Paranoid Android is easy on your eyes?

KM Worth a try for sure, but yes, your Samsung is not listed.

There is no worse scenario than an already "dead" phone. Besides, I paid only USD 150 including 50 bucks of credit for that phone new. Samsung wrote me to ship it to the US for repair. Non-sense.
What shall I download and try to install in your opinion? And would I have to use Odin? Thanks.

It was never approved by Google.
