EDIT: Is it just me or is this normal for QHD or display of this size to exhibit scrolling blur. Whilst browsing using chrome or XDA app anytime I scroll I find that nothing is crisp it seems to be blurry until the scrolling comes to a stop. With this type of quality display I expected better, or am I just being too picky? Anyone else notice this or have the same issue.
The display is QHD (2k) nor UHD (4k). Also there is no scrolling blur for me when I use chrome or XDA. Did you change anything in the phone?

My bad, lol... I haven't changed a thing. Adaptive brightness set at default ambient display switched on. No other changes, not rooted ATM, just stock??
I just got one with project Fi and coming from an HTC M8 I see the scroll blur. Makes me wonder about OLED TVs.
I've never seen this issue. Are you sure it is a display artifact and not some kind of rendering / performance improvement for scrolling in stock?
I'm using a custom rom.
What you could do is try and record your screen using an app like this...https://play.google.com/store/apps/details?id=org.mistygames.screenrecord. If the issue doesnt appear on the video but does appear to your eyes, then it is the screen. If it is on the video, it is your software.
Like I said, never seen it myself, though that doesnt mean its not there,

All TV technologies, when new are inferior to previous technologies that they replaced. The previous technology has always had time to develop. For instance, LCD TVs are pretty good now, but my 2006 and also 2009 LCD TV's have terrible motion "jerk". I still use that 2009 TV.
OLED have only been out what? 2 years on TVs? Yeah I wouldn't necessarily buy a 2 year old model.
If this issue is a screen issue, it's worth noting that the screen on the N6 is old OLED technology. It is not up to date, like the Samsung Note 4.
hello community
I bought my tab s T805 a few days ago and yesterday watched "The Strain" on it.
Everytime when a black part (hair, clothes etc.) moves, there was a caudate behind.
Very annoying if there are more black objects and the camera moves...the whole picture looks unsharp.
Seems like it´s a comon problem of AMOLED Displays, because my Note 3 shows the same behaviour.
Anyone else noticed this problem?
Maybe it´s only the display of my tablet...
what app do you use for media playback and whats the source? own blu ray rip or purchased online etc?
I use Plex, Video is H264 rip of the blueray.
The Plex server streams the video to the tablet.

Yea, I've noticed this a lot. Doesn't matter if it's a game, movie, or static image. Any deep black spots will "smear" across the screen a bit.
Damn...beside this problem, the screen is really great!
Maybe I send it back and get an alternative...
As far as i know, only TabPro and Note 10.1 (2014) also have the same resolution.

Good article. I disagree with one thing, though I've never heard of OLED described as holy grail of motion blur. It's the holy grail of black as the pixels can shut off completely. But as for motion it is pretty much in same boat as modern LCD. LCD now has very fast pixel response too (not as fast as OLED), but because of sample and hold it has motion blur. Ditto OLED.
Even the $25,000 LG OLED uses sample and hold and has some motion blur. So yeah don't expect great motion in your $400 tablet.
I though Samsung had fixed the motion blur or at least improved it by not fully turning off the pixels so it take less time for them to respond, so it`s not jet black more like dark, dark, dark grey
John.
Interesting side note. There will likely be a specific need for low persistence OLED displays for virtual reality applications in the future. This is an excerpt from the Oculus Rift website:
Low Persistence OLED Display
DK2 uses a low persistence OLED display to eliminate motion blur and judder, two of the biggest contributors to simulator sickness. Low persistence makes the scene appear visually stable, increasing the potential for presence.
Some facts about the OLED's used in the Oculus Rift:
http://www.oled-info.com/oculus-vr-shows-new-hmd-prototype-low-persistance-oled
Oculus' DK2 uses the Galaxy Note 3 AMOLED panel, overclocked for lower persistence:
http://www.oled-info.com/oculus-dk2-uses-galaxy-note-3-amoled-panel-overclocked-lower-persistence
I have been unable to see any motion blur on my T800, though i mostly watch animi, i do watch movies as well.
John.
It's easily testable with a black image with some dark details on it like this one. If you even gently move it around in an image viewer many of the details will simply disappear.
Are any of you with this issue using power saving mode? I found that the slower refresh rate in powersaving mode does cause some screen issues.

just came out today,? is will their be a mod to put note 8 120hz or im i going to hear the magic words ...no its hardware thing?
Um ... why , 2k screen at a 120hz would take some power. Plus with small size really wouldn't be worth it. High fps really only matters in shooters on pc. On a phone there are too many weak links to make it good for games that would call for 120hz..

Hz (refresh) is not the same as fps (framerate)...
And higher refresh rate actually makes everything smoother, including simple animations, etc. For example, I have a three monitor setup (2 x 60hz, 1 x 144hz), and you can easily see the difference just by moving the mouse cursor. Much smoother and easier on the eyes.
Razer includes a 4000mah battery...if Samsung bumps up the Note's battery capacity again in the future (and/or introduces further OS optimization for increased efficiency) then it could mitigate any additional draw in power. Personally, I think a Note 9 or 10 with faster refresh would be sweet

...I was replying to the other post (that I quoted).
Yes it can be done, the Razer just did it. Not likely on the Note 8 though, but can't really say for sure. I do know that the refresh rates of some monitors can be overclocked, but it only works up to a certain point (much like ram or processors). So even if it were possible to increase refresh on the Note 8, I don't think it would be anywhere the Razer's 120hz. Happy to be corrected if I'm wrong though.

i dont think the note even running 60 fully,its could be cool if their 60hz mod like the qhd 60fps,i think the note 8 exynos can handle 60hz or 120hz,that software not hardware

Just found this article which explains a lot:
https://www.androidauthority.com/120hz-displays-the-future-or-just-a-gimmick-782717/
Sounds like the refresh rate on the Note 8 could theoretically be increased through software alone, but that it would likely introduce issues such as screen tearing, etc. In contrast, the Razer's panel (for example) has hardware technology to reduce or eliminate these types of artifacts. So I'd say yes it could techically be done on the Note 8 to some degree, but even then the results wouldn't be great. Better to have the hardware that makes it work right and delivers the desired/expected visual experience.
OLED is not able to do those high refresh rates yet.... Its hardware
Even if you got it to work it would absolutely kill the battery and if/any games even are optimized for 120 hz is another story.

You can see the difference if you have the video/game that uses it otherwise it's number theater . I would venture most folks couldn't tell between 60 and 144 unless it was in action. 24 to 60 yes, but beyond 60 is splitting hairs. Also on the small form factor of a phone, with the control latency of a phone not sure tour getting bang for buck . I am aware that Hz and fps are different ,just as I am aware that using different refresh rates in a triple monitor set up is just asking for problems as well. To me it's just the same as THX speakers on a phone or Dolby Atmos on a phone, yes they're there but it's more like a gimmick because of the small form factor. I am also biased towards pc gaming , and could not imagine playing any serious shooter on a phone, just like I couldn't do it on a console either(but at least consoles have the horsepower now).
My biggest fear is this catches on and Samsung ditches it's Amoled displays for LCD just to get the specs for the next phone.

No as I said you can see the difference just moving a mouse (or watching movies, etc). Also, no issues at all in a triple monitor setup with different refresh rates, so long as you know what you're doing. Obviously if you try and play a game on 3 monitors at once with different rates then you're asking for trouble lol. Anyways, moot point now as OP's question has been answered.
Animation in android
Can the animations and UI in android currently even run at 120? Are they not rendered at or around 60fps?

I wouldn't put too much credit in this article. They seem to be sort of talking out of their asses on this.
Adaptive display technologies reduce screen tearing yes, but their main benefit is the reduction of resources. Allow me to explain.
Your free to correct me if I'm wrong but this is my full understanding.
When a screen displays an image it has to get told to display an image. However, it's not quite as simple as the CPU saying, please display an image.
The screen will continue to display an image until it's told to Change to a new one (think of when your PC freezes. This is why the image can sometimes freeze. The display adapter has stopped sending new images to the monitor).
So what happens when your computer is creating a new image, 1000x a second? Well, it would tell the display to "display" 1000 images in a single second, even though it's only capable of let's say 60 (this is where 60hzcomes from) this creates the tearing effect. To combat this there are controls we can use, Such as vertical sync, where we can just Pull an image from that 1000 image pool when we want to display a new image. For example, your phone might tell android, since it is running at 60hz to just pull a new image from that pool once every second. We could also limit the software to only create a new image once every second as well to combat this. The problem with these is they require CPU cycles. And they have an impact on the memory, with the frame buffer holding that 1000 count image pool. Ideally went want the CPU to only worry about creating an image when we 'want' one. So that it can move on to the next process in it's Queue.
With adaptive display technology, we can 'sync' these two numbers without creating a significant performance impact, and because we have synced them the overall smooth transitions require less motion smoothing, or blur effects that alot of movies might use to help create that clean look (This magic is why movies at 24fps look fluid). When it comes to Android, 120hz vs 60hz would most definitely be noticeable, so long as UI transitions and the OS itself had animations that could display 120 different frames. Currently I think that it does not. Also, let's be honest, until the hardware starts supporting it, android won't support it. We are starting to see that support now, in the Razer phone and in some Sony phones.
I am unsure of the currently refresh limits of OLED. I do know however that OLEDs response time is faster than that of LCD. Response time doesn't directly effect refresh rate, That would be the job of the display controller, or whatever that strip is called haha. Response time is important though as it'll determine the quality of the images being displayed at higher refresh rates. Which would be the significant factor in whether you would want your display running at 120hz or simply 60hz
Also... Before anyone chimes in, with "you can't see more than 60 frames per second" your wrong. Don't bother. Sorry, but you've done zero research.

Hey guys, just bought the Mi 9 after the Galaxy S7, and sometimes scrolling is really laggy on some more complex websites. It wouldn't annoy me that much but my S7 was much smoother when browsing. Same on different browsers and on the Mi 9SE too. Any fix or Chrome flags for that? Other apps, such as Facebook are smooth as butter.
I guess ads cause this, but I can't make them all filtered with Adguard, it also makes WiFi slower. Thanks!
I also do come from an s7 and whilst the scrolling is still choppy on the mi 9 in chrome, it was definitely choppier on the s7 for me, my s7 being relatively clean. If you're not into chrome that much, you could just use the mi browser as it's way smoother but probably with less features.
As hard to believe as it may be, I kinda like it being a bit choppy because when the scrolling is perfectly smooth on this phone like when using facebook I notice a lot of blur and that annoys me a lot
I've just installed Bromite browser, seems much smoother now. Have you tried turning on DC dimming? Maybe that would help with the blurring effect.

DC dimming definitely doesn't make it better and might even make it worse, though I'm not completely sure as I have used it for about 15 mins. The only ways to decrease motion blur would be to decrease pixel response time and/or increase refresh rate.

For how long you have been using the MI 9? I switched a month ago, and there may be some blurring there and there, but it's not that annoying for me. I was more annoyed by the browser lagging. However Bromite browser makes it more usable.
I was really disappointed by the night shots first, but Gcam makes much better snaps than the S7 did.

Been using it since the 26th of july. The blur is a bit more pronounced than what I see on a true flagship like a note 10, problem is that even on those 1000$ phones the blur is pronounced because smartphone manufacturers never made it a priority to improve it, at least not the ones that still make 60hz phones.
I'm disappointed by pretty much everything the camera does, haven't tried gcam yet but that still wouldn't change the fact that using stock app this phone takes meh pictures all around.
I've kinda led your thread into the off-topic abyss and am sorry for that

No problem, it's a solved issue.
Really you are? It's not that bad. I mean it's not that easy to use as S7's camera was, as I could take perfect pictures while walking etc (I guess because of the OIS), but it makes nice pictures. MIUI is which a bit unfamiliar for me, but at least I can theme it.
I guess you should check the GCam thread, it really improves many things with the camera.
Ok so I've had the X5 Pro since launch and while on paper it's spec spells awesome device something I cannot live with anymore (And also they're just ignoring users for updates to fix the issue) Repeatedly I've asked support to add a fixed 120hz refresh rate option for those that want a smooth scrolling experience all the time because the fact is some of us are sensitive to the jitters that are constantly happening with this screen because of the refresh rate constantly dropping to 5hz 5fps is the most annoying thing to me.
I get it I get it's to save a little juice on the battery but for those who don't give a **** about 10 mins difference in battery give them users an option to fix the refresh rate at 120hz all the time!
It's pissing me right off the amount of jittering in every app you scroll with because the second you take your finger off the screen or scroll in the opposite direction the micro stuttering rears it's ugly head, Samsung and Google have a fixed option whether in the main settings or the dev options but not Oppo and for £1k device I'm afraid it's junk to me, I've had 3yr old devices smoother than this and it's just not acceptable.
The fact it has still not been addressed with an update after all this time just goes to show they DO NOT LISTEN to their users for what needs fixing.
Rant over, Some people probably don't even notice this issue or they simply just don't care but imo shelling out this much for a flagship device of 2022 that scrolls and jitters like a 5yr old device is just rubbish in my book, I won't be buying anything from Oppo again, I hope in the future these companies start to listen to their end users before these companies that are trying to compete in such a heavily filled market destroy themselves before they even start to get a large customer base, Forget the apps that force 120hz like the Chinese app it doesn't work properly all the time and it is not a solution for a lazy manufacturer that can't be arsed doing it themselves.

If you're unhappy with this device, for god's sake please don't replace it with the more expensive Galaxy S22 Ultra exynos version which I owned before seeing the light and buying this device
Oh I don't intend to, I've had an exynos variant from an older model previously and regretted it lol, I won't make that mistake again, If I was going to get a galaxy next time it would be a Qualcomm variant.
