Nexus 6P on 240fps Flickering / Blurry / Pixelated

Hi Folks,
I really couldn't find any thread to my issue... So I started this one... I hope this is okay.
I got my N6P yesterday and so far I love this device.
But something is very weird for me... When I take a video with 240fps the result is very pixelated, Blurry and Flickering
I uploaded a video I took on YouTube... Could somebody please tell me... Is this normal?

Or do I need to give it back?
Thank you in advance for your replies.
Regards
Jay

Me and my brother have this issue on our 6Ps as well

The graininess/pixelation is from the low light. The flickering is from the light source itself. Mine do the same thing in my living room where I use LED lights. It has to do with the fact that the lights are actually flickering very quickly, too fast for your eyes to see. When the video is recording at such high FPS, it can see the flickering of the light. Using different light sources will help limit the flickering, such as filming outside or with constant light from a different type of bulb.
Here is a video shot with my 6p outside in the late afternoon with the sun partially set, but still a lot of natural light: https://goo.gl/photos/caUHhnVCFR2AoSu68
Here is another one shot in a house lit with fluorescent (or maybe LED) bulbs, which show the grainy picture from low light, and the flickering: https://goo.gl/photos/nM4K6NGZbRJwTd776
Both shot on the same Nexus 6p, both normal.

Display issues

Hello guys, suddenly I'm having display issues on my k20. I've attached a link to the video, when i pull down the notification bar, look how the blacks are loading a bit late. When i turn off dark mode, i see no issues like this, it's just the beautiful display again. Even i had same issues with my dark wallpaper. Please check, if you've same issues. I'm really concerned about it. Also, this maybe screen flickering but when i increased brightness, the issue didn't disappear, it was still persistent but at lower levels.

That's normal behavior for amoled displays.

1st: If this is the display problem, how can you expect we can see this on a screen capture??
2nd (probably because of the 1st): I can't see anything wrong.
3rd: I have no display issues at all.

Can't you see that voilet-ish colour instead of black when I'm swiftly moving the notification bar? It's clearly visible in video, you might want to check again.

Nope, watched it at least 5 times, on my PC and my 9T. Can't see anything peculiar.

I can not see anything wrong or violet at all. Am playing this on my computer at 1080 resolution and 0.25 playback speed and there is nothing to see.
If your screen is faulty, we are not able to see it on video you have shared with us of course

DAMN IT! Even i see nothing from my laptop
I think I'm having screen issues, only when its dark mode, else the screen is working absolutely fine!
I need to get to the service center ASAP! :crying:
Edit: Guys can you try doing the same and look if the issue is persistent in your screen too?! It would really be helpful for me.

It's normal for OLED panels, some are better, some worse. My phone has it too. No need to go to the service center.

I too have it brother. Dark mode has it normal mode doesn't. It can also be noticed if you open youtube and scroll back and forth quickly. The blacks seem to be spilling or streching. I saw that on your video and I don't know if it is normal or not but i too have that and wanted to ask someone about that.

People are claiming this to be normal, but after searching a lot i got to know these kind of issues come after 1-2years, not in a week or month. So I'm trying my best to replace my device or get the screen changed. I don't understand why Xiaomi is keeping the colours to pure blacks when they know their displays are facing smearing issues. I hope someone just changes that pure black colour to very dark grey colour, system widely. Some developer tested(on OP7 pro) the battery consumption difference with pure black and dark grey and it turned out that, dark grey consumes only 0.067% more power than dark inky blacks. I'm humbly requesting developers to change the colour, or at least have an option for the same.

My display when there is low light, the brightness is set to low and the image I see on the display is darkish I can see a vertical line at the left side of the display, is this normal or should I return It?

It's normal for Amoled screens (from first day of use). Just search for Amoled black smearing and you'll find a lot of videos and articles. S10 has it, iPhones have it too.

I have faint vertical lines on the right of the display when the brightness is low which is how I normally use it. I also have black smearing on pitch black to dark color transition. I think thats normal, it doesn't really bother me all that much.

The best way to reproduce this issue is turn off brightness to minimum and turn on reading mode to max. Then you'll see delay of displaying some colors (mostly gray)

My k20 has this issue and it's annoying that after paying for a flagship killer, we just got a cheap display which is not just low in quality but has these issue in dark mode which i think most of us use. Interestingly when i record this from screen recorder,it doesn't show up much but the same can be seen visually. So, this is definitely an issue that redmi is trying to let go.

As you "record from screen recorder" you do not record from the screen as you may like to think. You capture the video signal BEFORE it gets to the screen. So any imperfections caused by the amoled screen do not show up on a screen capture.
Anyway, this is a normal weakness with all amoled screens that I have seen.

It is soooo annoying when in dark mode at low brightness, I feel like I couldn't stand it anymore. The worst experience of display usage ever.
Maybe with DC dimming update that might happen someday, the issue won't be as intrusive and pronounce as it is right now. But whenn???
UPDATE:
So I found a workaround for this issue with an app. It's called Screen Balance. Basically it adds a filter overlay on your screen (ineffective on notification panel, because android restriction). Set it to either flourescent or flourescent (warm) at 15% strength minimum, and both brightness and contrast at 100%. You won't see perfect black anymore, but very close to that and no smearing effects visible unless you're really trying to.

I've bought Mi 9T Pro and have the same issue (also see it in your video). Did you fixed that?

Screen defect alert. Check you phones!

I've got a weird bluish green glow just below my speaker grill.
NOTE: IT IS NOT MOTION SENSE
I've used motion sense and can understand why you think it's related, but it is not, I can assure you.
It seems like a manufacturer defect. It's there all the time. Even on the lock screen. It does not show up in screenshots and I did a factory reset to see if it would go away. It did not. I need to find others with this issue. Go in a dark room and look at the very top of your screen. You might see a discoloration that does not go away and even shows up with your ambient display.

Dude, I saw it too. That's a light line designed by Google. It's also an indicator when wave hand to switch track.

Yes, it is the motion gesture light for when music is playing, or when a call is incoming. One can always disable motion gesture if they find it bothersome.

Yeah. Like I said, it's not motion sense. It's there even when it's disbabled, on boot, on the lock screen. I have a replacement coming soon. Just watch out for it. I can't be the only one

Yep I've got it. It's like the top of the screen has some light leak that on grey makes the screen turn green.
Used a screen tester to confirm it. In the UI it looks almost intentional but it's pretty apparent.

Really very little light bleed on mine. I would't have noticed it if I haven't read this post.

Wow. that's annoying looking. No light bleed here. Sorry to see you're having issues :/
Totally get were you're coming from. I had a 4K TV with some light bleed and even worse clouding issues when watching HDR content. Once you see it, you can't unsee it.

just got mine nothing like that either. All is good here loving it :good:

Download https://play.google.com/store/apps/details?id=com.gombosdev.displaytester
Switch to 18% grey (18% for all 3 sliders) and lower brightness (swipe in between the bars up and down) to about 2-3%

I can see a slight green shadow on top... I thought it was intentional, but now I realize it's not.
Please report here what you finally do.
It's something I can clearly live with, it's very slight, and I can't see it in daylight, but obviously I don't want. Maybe I'll keep it some weeks and see how all this evolve before I place a RMA request.

Screen issues when watching video at low brightness

Hello guys, this problem is more noticeable when watching videos at low brightness (>50%) in a dim environment. Shadow details in dark scenes are completely blown out and take an unnatural oily greenish hue. Like a pastel painting.
If anyone intends to replicate it, first make sure you're in a dark room. Bedtime with minimal ambient lighting should be the perfect situation (if you're the type who's relaxing watching movies on their phone before sleep). Otherwise you won't be able to notice the problem easily. Then, make sure you're watching a dark scene since the problem is only apparent where there is shadow.
A good example is the opening scene in Blade Runner 2049 with K and Morton having a conversation in a dark house.
This issue manifests with all common apps. Netflix, Amazon Prime Video, YouTube, Google Play Movies.
I used to have the exact same problem with my Galaxy S9 when it was just out but Samsung eventually issued a software update after a couple of months that fixed it. So this has to be software related and not an actual problem with the screen itself.
Google should be made aware though.
There is also an XDA topic describing it with photos too so you know what it looks like:
https://forum.xda-developers.com/galaxy-s9-plus/help/colour-blending-blacks-problem-t3765385
Is there anyone who's already experiencing it with their Pixel 4? Should be the same with XL.

I checked on those sources and I don't have that issue.

It only shows up at extreme low brightness like < 15%. But every OLED phone I've used suffers from this.

Camera issue needs to be reported ASAP

UPDATE: Check link for video
https://youtu.be/ucS8Jv49t-0
And this is a Brand New sealed box Galaxy Note 20 Ultra!
I need help to report this issue to Samsung, i cant find any reference online, tried with my GN20 Ultra and my wifes as well.
Alright, heres the issue. In a very dark room, when trying dark mode with the ultra wide lense, 50% of time after a long processing time, photo comes as a white noise with lines, i will post some pictures, and trust me i can make this happen anytime. So far it only happens with the ultra wide lense using dark mode on a really dark environment like stated.
Ok so now after uploading some photos i realized while zooming happens the same, wtf!
Can someone else please give this a try and report back!

I would say these Pics are enough as reference.

Can you try with your N20U?

I could not replicate.

That could be hardware (the banding indicates that)... if it persists.
Noise should be more or less evenly spread out.
See if lower temperatures alter it.
Try clearing cam data and clear the system cache from the boot menu. Do a hard reboot.
My thought is it will still be there...

Just tried as you suggested, not happening on my Ultra (SD).

Did you try in a completely dark room? Dark mode enabled and ultra wide lense?

UPDATE:
I went to Best Buy and exchanged the unit, now i have a "brand new sealed box" Galaxy Note 20 Ultra, i went home, went to the closet, really really dark, dark mode enabled, using ultra wide lense, out of 5 shots, got 3 with the same strange noise!

Possible RF interference?
Any RF sources nearby ie a router, nearby radar, radio antenna etc?

Nothing, i just did a screen recorder, so i can sort of prove whats happening, but idk if i can upload videos here! It keeps happening, but like i said, dark room, as soon the sensor sees any sort of light it will give me a pictured as expected, grainy, or dark but a picture!
This is crazy, and i can do the same with my wifes GN20 Ultra!

Grainy is normal, prominent lines are not.
In a perfectly dark room you'll see random background noise from the cam sensor it's self; this is normal.
If you cool the cam the noise level will decrease and increase as it gets hotter.

If it captures ok low light images... I'd say don't worry about it.
Play with it and have some fun...

It was not completely dark but I just tried again in a completely dark room and just got a normal black picture. I'll try a couple more times later incase its not consistent.
