Yep, the PWM dimming is a problem for me too. I'm actually surprised that most people don't see the flicker. In addition to actually picking up distinct low frequency flicker at the lower brightness settings, it makes the image on screen somewhat unstable if the phone is moved relative to your eyes. It's kind of the opposite of sample and hold motion blur, in which moving images on screen appear blurred because there is no flicker. The screen is constantly turning on and off, so when you move that screen through your field of vision the elements on screen (such as text) cannot be tracked easily. It kind of looks like the image is randomly broken up.
The Note 3 was the last Samsung OLED panel which didn't use PWM at 100% brightness; The modern panels flicker even in "boost" mode, though it's fast and much harder to detect.
Totally agree.
It's been an issue for a long time... and the new PWM management (geared and engineered to satisfy VR applications) is no better...
See this in XDA forum. Proof is in the pics that the members took of note4 screens using high shutter DSLR. Look at page 6,7 for the pics and info on the new PWM protocol.

And Samsung wants us to put this 2" away from my face for VR? No thanks.

Actually, all of Samsung's OLED displays are still Pentile, even the Note 7. "Diamond" configuration if you want to get technical, but it's still just a variation of pentile. I'd agree with the general consensus that they still look great, but that's a lot of processing work done to maintain a resolution that you will only see on green pixels.
"At a high level this is a 5.7 inch 1440p Super AMOLED display that is made by Samsung with a PenTile subpixel matrix that uses two subpixels per logical pixel in a diamond arrangement."

Not thrilled with the PWM flicker either, but that's a separate issue.
This
And for you guys who are interested, (posted previously) regarding Amoled and The SUBPIXEL arrangement...
I took the time to take some pics of a new s7 and note7 when I was at Costco and here they are, labeled.
I call the issue "pixel hang"... The printing industry will call it "miss-registration".
Pls look at them with an open mind. And let me know if you can see/understand what I'm referring to.
The Google search bar I always refer to:
Look at the pixel hang/miss-registration
Pictures taken with my iPhone with a macro lens...
Do you see the pixel hang/ miss-registration?
This pixel hang is apparent on ALL hard edges, on ALL displays using the "sub-pixel". Pentile or Diamond pattern amoleds BOTH have it because of the SUBPIXEL.
Below is an example of "colour registration" they in talking about.
Then, here's the iPhone's regular Rgb IPS lcd close-up... Notice NO pixel hang/miss-registration.
Because the ips lcd displays DONT use the SUBPIXEL arrangement, there's NO pixel hang... Here's the same pic zoomed in: absolutely sharp, great looking edges.
Next photo is of the LG G4's IPS display.
As you can see in the Amoled screen close ups, the pixel hang is very apparent.
Without the macro lens, you can still see it. I can see it, can you? You have an S6 - look at the hard edges, and you will see what Samsung has been feeding people.
Now pls keep in mind, I know that Amoled screens have advantages like HDR capability because of its high contrast/Colour gamut, infinite blacks, etc
But this is a disadvantage I cannot overlook. I've always noticed it since the Gs3 and Gs5,6,7 have gotten better because of the higher res... But still noticeable.
..
I hope that when the Amoled screen is implemented into the iPhone, they find a way to NOT use a SUBPIXEL design.
Anyways,
Displaymate does have good reviews, measurements, and factual figures- yes, BUT This is an important issue (plus screen flicker) that Displaymate has forgotten to note in their reviews, therefore, their conclusion may not be accurate.
