Willyman's device isnt defective. Same issues here. Here is scrolling quickly through youtube for me. I'm on t mobile not rooted. Really tempted to root and try that fix.
[Galaxy Note5 General] scudzilla:
Here are two SS i took. First is finger flick scrolling, the other hold scrolling.
[Galaxy Note5 General] Chord_Hugo87:
if you are having this issue, root your device and try my build.prop to see if its fix the situation, I need more tester to confirm that it works.
[Galaxy Note5 General] sparksjordan58:
Wow
[Galaxy Note5 General] Willyman:
I seems to have at least something to do with RAM management. On occassions, Facebook or Youtube will scroll fine. If I remove the cache it stays fine. But when I close the app from the multitask window and open it again, it will stutter the worst.
[Galaxy Note5 General] mrlynch:
Out of interest after they reset your phone yesterday did you try it out before you did your restore? I imported all of my data straight away with Samsung smart switch so never tested a fresh install. I keep toying with a factory reset them setting everything up manually just to rule out any old phone data being the issue.
[Galaxy Note5 General] Willyman:
Not really, they had me fill in my gmail on the spot so it immediately started downloading and restoring.
[Galaxy Note5 General] mrlynch:
Ok I think it's the only option I have left to try, especially now my Swype keyboard had started lagging and taking a second or two to appear.

It looks like we're in the minority so I think it's going to be a case of finding a spare few hours at some point.

One quick question, are you using a custom launcher?
[Galaxy Note5 General] Willyman:
Yeah. Nova.
[Galaxy Note5 General] mrlynch:
Same, I just tried switching back to touchwiz and it seemed a lot smoother initially - although the bars are still spikey. I don't know if it was just going through a "smooth" phase as its done this for some periods of time before. I'd be interested to see if it makes any difference for you?

Also, I am going to be reflashing the firmware using Samsung Smart Switch, this guy put a video together showing how to do it as his S6 Edge was rubbish out of the box and reflashing the firmware in one go (rather than installing the OTA update) solved it.

https://www.youtube.com/watch?v=y8AZyalTf5Y#t=31
[Galaxy Note5 General] Willyman:
Well that's essentially what they did in the service centre yesterday. I tried it before myself and it had no effect.

Let me know where you get with keeping Touchwiz though ;)
[Galaxy Note5 General] mrlynch:
I've just finished a complete flash overwrite using the method above and manually installed and re-setup everything (rather than using a restore), i'm leaving it on Touchwiz for now. So far the results are promising but i'm going to see how it goes over the next 24 hours. I'll try and post an update tomorrow, hopefully with some screenshots.
[Galaxy Note5 General] mrlynch:
So 24 hours later and I am very happy with the phone. The entire phone just seems so much smoother and browsing is now enjoyable again. I've attached my latest test on YouTube.

[Galaxy Note5 General] Willyman:
I tried that before. When you did it, did it completely wipe your device?
[Galaxy Note5 General] yakuzlin:
Odd, the smartswitch application on PC does not work for the Rogers Note 5 (SM-N920W8). When under Device Initialization the Latest Version line shows nothing, Current Version line shows OGD for PDA, Phone and CSC. When I try to proceed, it says "This device's version cannot be updated"
[Galaxy Note5 General] mrlynch:
Yes it completely wiped the device and then proceeded to install the latest firmware in one go. I'm wondering if my problem was the OTA update that came down the day I first got my phone. With this method the OTA update is part of the firmware file that gets flashed so no chance of the update causing issues.

Another potential cause could have been using smart switch to copy my old phone data, these migrations have so much data from the old phone these could also be a source of the problem. With this in mind once the format and install were complete everything seemed really smooth so I manually setup the phone.

The other theory is it was just a bad flash from the factory.
[Galaxy Note5 General] Willyman:
That's what's so bizarre. I've tried flashing it with stock firmware before. Both via SmartSwitch and Odin. It would change the firmware, but not wipe the device. No idea what was causing that, I even made a thread about it but no one had the answer.

Either way, they did flash firmware and wipe it a the customer centre and it didn't improve. I will go back there tonight.

Just for my understanding: you never see those large spikes in the GPU anymore?
[Galaxy Note5 General] Willyman:
Update

Received notice of a new update today. So downloaded the new firmware from Sammobile, flashed using Odin. Again... it didn't actually wipe my device. It just updated the firmware. Still did a complete factory reset afterwards and setup as a new device (so no restore). Only installed a bare minimum of apps to try out and compare (Facebook, Youtube, ...) Same same... bad scrolling.

I'll go back to the service center today and discuss getting a replacement. At this point I'm more and more getting the feeling it's a hardware problem on mine. If the problem should have gone away by flashing firmware, it would have by now.
[Galaxy Note5 General] rlsroufe:
Its software, not hardware. I was having same issues, but rooted my device and flashed arter97 kernel and enabled f2fs and now scrolling is MUCH smoother. Feels like a completely different phone.
[Galaxy Note5 General] Willyman:
So how come for some people it seems to get better when they flash stock firmware?
[Galaxy Note5 General] rlsroufe:
I don't understand, firmware is still software. If it was a hardware issue, it would persist no matter what firmware you flash.
[Galaxy Note5 General] Willyman:
Sorry, I should have made myself more clear.

I'm not denying that software/firmware can cause bad scrolling.

But I've done the same steps as +mrlynch in this thread and have not seen an improvement at all. So I was wondering if besides the software issue, there is a potential hardware problem also able to cause this problem.

An other thought: are some firmware variants running on F2FS and others not?!
[Galaxy Note5 General] mrlynch:
The only time I see large spikes is when i hit the end of the screen (either top or bottom) or when new content is being loaded. The YouTube app loads more videos each time you scroll and each time this causes some delay as the content loads, if you scroll down until the videos stop loading and then try it then there are no spikes on mine.

All of the phone menus are silky smooth and most websites are spot on, even media heavy sites like the Daily Mail are really smooth although XDA for some reason (I think all the adverts) can be a bit hit and miss.

Overall though after 2 days I am so glad I took the time to start over again, the phone is now working how I expected it to.
[Galaxy Note5 General] Willyman:
Apologies if it sounds like I'm a broken record, but I just want to make sure I get it right. When I close Youtube (true multitasking view) and then open again, scrolling is bad. If it was still open, of course it's better. When you did your screencap, was it already open or cold booted?
[Galaxy Note5 General] mrlynch:
From a cold boot if i scroll down on youtube i will get spikes as the content loads, as soon as i scroll back up there are no spikes, and if i scroll back down there won't be any spikes until additional content loads again.
[Galaxy Note5 General] Willyman:
Yeah, that's what I thought. Similar behaviour here then. The update today seems to have made a small improvement actually.
[Galaxy Note5 General] Willyman:
I've just discovered something utterly bizarre:

Scrolling in Facebook and YouTube is smoother when the apps are in split screen view. If I open both apps side by side the scrolling is smoother than when I open the same apps individually... Maybe there's a clue in there to explain why the issue exists in the first place.
[Galaxy Note5 General] Willyman:
Just checked: exact same story with chrome.
[Galaxy Note5 General] mrlynch:
Maybe it's because a smaller amount of media is visible when scrolling? What happens if you resize the window so it takes up 90% of the screen, does this impact it?
[Galaxy Note5 General] Fightoffyoredeamons:
I had the same thing happen to me on my Tmobile Note5. Is there anyway to completely wipe it?
[Galaxy Note5 General] Willyman:
Nothing I've tried on mine has made it work like the guy explains in the video. For me it just updates the firmware without wiping the device...
[Galaxy Note5 General] lp1527:
Super frustrating problem - I have it all over the place in my one-day-old N5. Twitter App is by far the worst - unusable. Have wiped, etc. and problem remains. Don't think we should need to ROOT to fix this crap! Makes me miss iPhone (sadly).

If anyone has suggestions for non-root fix, certainly appreciated.
[Galaxy Note5 General] DNK01:
I'm using my gold Note 5 for two days now and I don't have any major problem with scrolling. I use Firefox browser and its buttery smooth. I also checked Spotify for any lags and didn't find any problem. Facebook is fine but not great. P.s: just downloaded the native twitter app and its horrible almost unusable.. sadly. But I always thought it was a bad coded app anyway so use Fenix instead and you'll be fine. Otherwise this is a very good phone I definitely recommend if you're thinking of buying. Cheers.
[Galaxy Note5 General] ambervals6:
Turn on force gpu rendering if you have scrolling problems.

Sent from my SAMSUNG-SM-N920A
[Galaxy Note5 General] daffie:
Good advice! It really does help...much better and smooth scrolling.
[Galaxy Note5 General] ambervals6:
?

Sent from my SAMSUNG-SM-N920A
[Galaxy Note5 General] Willyman:
It does seem to help. Any negative side effects to this?
[Galaxy Note5 General] rlsroufe:
Battery life. Running gpu more is more battery intensive.
[Galaxy Note5 General] daffie:
I've been doing a test today by using my new Note 5 almost continously (with the Forced GPU setting activated).

The result is almost 7h SoT and 14 hours battery life. That's not too shabby imo.

[Galaxy Note5 General] ambervals6:
Not really. Maybe 5 minutes less at max.

[Galaxy Note5 General] Willyman:
For those with knowledge of Rooting and modding, does this tweak for the OnePlus One have any relevance for the Note 5 as well?

Developer zephiK tracked down one such instance of lag-inducing code in the scrollingcache class of Android. He noted that some developers still have this option enabled in the internal config file of their apps which causes unnecessary slow-down when scrolling.

To alleviate this bottleneck, he created a smooth scrolling mod that universally disables the scrollingcache feature. The mod will be flashed through TWRP, so an unlocked bootloader is a must.

http://oneplus.wonderhowto.com/how-to/fix-scrolling-lag-apps-your-oneplus-one-0158164/
[Galaxy Note5 General] daffie:
I can confirm this...battery life with this option enabled is as good as it is without.
[Galaxy Note5 General] rlsroufe:
Yeah I used to do this. The mods zephik created for certain roms definitely showed a noticeable improvement in scrolling. When disabling scrolling cache was an option in roms or you add persist.sys.scrollingcache=4 to the end of your build.prop I see less of an improvement. Just added the line to build.prop on my phone and didn't see any improvement in the usual apps but I'm already rooted and running arter97 kernel with ram fixes so scrolling is already pretty good.
[Galaxy Note5 General] Willyman:
I'm really keen to try this kernel, but have yet to see any confirmed support for my variant. Did you switch to F2FS? Do you reckon this made a big difference?
[Galaxy Note5 General] rlsroufe:
Yes I did format all partitions to f2fs. I did it pretty much right after I rooted so I cant say how much it has helped but others have said they couldn't tell much difference.
[Galaxy Note5 General] FunkyMcBain:
This scrolling is ridiculous. I will abandon this device for this one thing. Who in QA would allow this
[Galaxy Note5 General] WizeGuyDezignz:
Cool, which phone are you gonna get?
[Galaxy Note5 General] FunkyMcBain:
Back to my Moto X that thing never once had this issue. This is a $1000 phone.... unacceptable.

I have to go through this thread because obviously I don't want to but honestly, this is really really poor software. I don't even have issues like this on an iPhone 4
[Galaxy Note5 General] WizeGuyDezignz:
So you are gonna go to an inferior phone just for scrolling that bothers you? To each his own.

In my opinion, the Note 5 is better than the Moto X in every single possible category. But if the scrolling bothers you that much then I guess you gotta do what you gotta do.
[Galaxy Note5 General] FunkyMcBain:
What does it say about the rest of the system when an 8 core 4GB RAM device cannot scroll through a page without stuttering.
[Galaxy Note5 General] DNK01:
Native apps scroll with almost no lag but some third party apps like twitter make your face turn red.
[Galaxy Note5 General] Fullmetal Jun:
My S6 has same dumb scrolling issues! Dumb TW software! You know what? Even my Moto E 1st gen on 5.1 has much smoother scrolling.

Came on your forums to see how the new/updated TW is, but they still can't get it right!!
[Galaxy Note5 General] DNK01:
For those who have lag issues just do a factory reset after that disable all the bloat with "Package Disabler Pro" or any other disabler app. The scrolling lag is almost completely gone on mine.
[Galaxy Note5 General] Willyman:
Tried all of that before. Didn't help.

Anyone found any proper solutions? It still bugs me a lot...
[Galaxy Note5 General] DNK01:
I'm afraid not. You can try to install custom rom.. or you can wait for Samsung to fix the issue with Marshmallow update. Cheers.
[Galaxy Note5 General] FunkyMcBain:
I have the exact same experience. After Package Disabler and reboot my lag is all but gone. Whatever the hell they had running in the background was ridiculous.

One thing to add, use Package Disabler Pro plus the 'basic' xml from the debloating thread. If it doesn't work for anyone maybe it some kind of crapware from the provider that you need to disable. The difference is night and day. Bonus is that battery life after that is ridiculous. With my typical usage I still haven't seen less than 50% battery at the end of the day.
[Galaxy Note5 General] Willyman:
Can anyone with a rooted phone try if this works:

http://xdaforums.com/showthread.php?t=2003062

Basically disabling the scrolling cache will reduce lagy and chunky scrolling. You won't notice a huge difference unless your scrolling through something your phone usually has a hard time with. Anyone that has Rom Toolbox would understand chunky scrolling on the first page of the app. So if you have the app, test it there. In general, icons will appear instantaneous and everything will run a bit smoother.

So here is what to do...

Use your favorite build.prop editor and add a new line.

persist.sys.scrollingcache

Set it's value to 3.

Reboot.

If you really want to make things extremely more responsive then adjust your vm.stat_interval. I do believe the default is 10. If someone could verify it before you change it let me know. Setting the value lower will increase the responsiveness of your phone a very good amount! Start at 8 and slowly work down. There is a chance you will become unstable so use caution. I can say I have set it to 1 (lowest setting) without a single issue.

Do not expect to increase your benchmark with this because it will actually drop a little. This is a perfect example of the whole benchmark debate. Your phone will be flying but quadrant won't show it.

Use the "SCOL" app to adjust vm.stat_interval and save your value. There is no need to reboot and the results of your changes are instantly applied.

Yes. It is most likely going to effect battery life.
[Galaxy Note5 General] rlsroufe:
Thanks for this. I tried the scrolling cache mod before and it didn't seem to help that much. Tried the vm.stat interval mod by itself and didnt seem to make much difference either. Scrolling is already much improved with arter kernel and custom roms with ram tweaks, but adding both together seems to added a bit more smoothness and really gotten rid of any remaining scrolling jankiness. Cool!
[Galaxy Note5 General] Willyman:
Wish I had seen this comment an hour ago :D

I brought the phone back to the Samsung service centre around the corner. They're going to do a full check of the hardware to see if there's any issues. One thing I found interesting of this most recent visit to the service centre: the guy didn't even question me about whether it was an issue or not. I showed him some examples and he said they would have the engineers have a look at it. Anyway... 99% chance tomorrow they say there is no issue whatsoever, but I guess it can't hurt to try.

Reason why I went back is because I've been reading a lot of the forums on the recent Galaxy family (S6 to Note 5) and it seems some people are really obviously seeing problems and others cannot seem to find these issues.
[Galaxy Note5 General] rlsroufe:
I think people's perception of what is smooth or not is very subjective. Some people also don't correctly distinguish between speed, smoothness and lag, saying the phone is smooth when it is just really fast or responsive. You often don't recognize how bad the scrolling is until you compare it to something that is really smooth or are really looking for the dropped frames and stutter. It is also complicated by being worse in certain apps than others.
[Galaxy Note5 General] Willyman:
They said they ended up replacing the motherboard. To me that says they also found something odd in their hardware analysis.

The performance seems better. It's still not perfectly smooth (compared to OnePlus One), but it's better than before. I would even say it runs cooler. I'll give it a few days to see if it's a placebo effect playing tricks on my brain or if it's truly better.
[Galaxy Note5 General] daffie:
I can confirm this tweak does work. Scrolling is much improved on my Note 5. Btw I already use some RAM management tweaks and have also set 'force GPU rendering' in Developer menu. Scrolling with your additional tweak is now very very smooth indeed! Thanks :good:
[Galaxy Note5 General] Willyman:
I'm a complete noob when it comes to rooting, so I have to ask... When I root the device it will void my warranty?
[Galaxy Note5 General] daffie:
Short answer is yes, although in many cases Samsung doesn't seem to be bothered and will provide help or fix phone under warranty even when device has been rooted. Can't give you an airtight answer unfortunately.

Further regarding smooth scrolling...

Flipboard continues having a (small) issue with scrolling. I find the tiles to be refreshed continually when scrolling, and scrolling always has small hickups. I've had this issue with Samsung S6, Note 4 and now with my Note 5. Before using Samsung phones I didn't encounter this issue. Therefore I must conclude Flipboard and Samsung are not very much compatible :silly:

Hoping for a miracle of some sort which improves Flipboard scrolling smoothness....
[Galaxy Note5 General] Mandeep148:
This phone can become number 1. But scrolling kags irrirates me and taken this phone to lowest hardware phone..
[Galaxy Note5 General] daffie:
Where do we find the vm stat interval value...how do we change it? Cheers!

Send from another Galaxy (Note 5)
[Galaxy Note5 General] IIEtCII:
I want to get this phone , but the scrolling problem and RAM management irritate me .. Does debloating the device helps ?

Since my current device is not the best performer out there , I really want to upgrade to something that will blow my mind . and I don't intend to root my phone right away ..
[Galaxy Note5 General] Luca81:
I think I found a solution for the stuttering in 3rd part apps.

I use youtube and FalconPro (twitter) alot and the scrolling stuttering was too awful. I was going to sell this phone!

Today after the third hard reset in 6 days I found that the outdated youtube app was smooth, but after the update was sooo bad!

I downloaded from play store FalconPro and it was just awful.

So I uninstalled the apps, I manually downloaded and installed apk and magically the scrolling in youtube and FalconPro is smooth!!

Now I'd like to know what's wrong with Play Store....Is it bugged? Are Play Services bugged?
[Galaxy Note5 General] luciferiusXI:
I turned gpu rendering on and all works great.
[Galaxy Note5 General] Luca81:
It didn't work for me. I tried everything suggested here and in other forums but no solution.
[Galaxy Note5 General] Willyman:
How did you uninstall YouTube? Are you rooted?
[Galaxy Note5 General] Luca81:
No, I uninstalled only the updates from the app manager.
[Galaxy Note5 General] Willyman:
Don't know what to say, I'm stunned. That really seen to have worked. It's not perfect, but much better. No idea why. I do remember it being smooth after a fresh wipe and then it got worse.

I'm gonna try the same with Facebook.
[Galaxy Note5 General] Willyman:
By the way: what is a good site for the latest apk's? I installed some for YouTube and Facebook but playstore immediately afterwards gave me newer updates...
[Galaxy Note5 General] Luca81:
I don't know why playstore give new updates, the version I installed is the same: 10.40.58 for youtube

hello i got the same exact problem

i have same issue on my note 5 :( i bought it on 5-11-15 and i paid al ot about 600$ (64gb) so this is unacceptable from sammy , hear me out i had the htc one m8 it was nice and smooth on kitkat then came android l that's when i noticed the horrible scrolling and i thought it was just because of age and maybe because i rooted the phone so i bought the s6 after jon from techno buffalo said scrolling was smooth (lair) i dropped 700$ on the s6 right after he said that and surprise scrolling is chobby and laggy at this point i was defeated :/ went out sold my s6 and bought an iphone :( please don't judge me, i used the iphone for 6 months but i couldn't take it anymore i hated ios so freaking much being an android fan since 2013 that's when i got my first smartphone ... i went in to the store knowing that i might have the same issue with the note 5 but the iphone was driving me crazy so i got the note 5 and here i am sorry to bore you guys i'll upload some screenshots if someone replies to me
[Galaxy Note5 General] xantrk:
Having the same issues on my edge+. Any fix ? Or any sign that they are aware of this issue and will fix in marsmallow update?
[Galaxy Note5 General] Willyman:
I have yet to find a method that completely eliminates the issue. I've since starting this thread rooted my phone and installed a custom kernel, but even though this has improved things significantly, it is still not quite as smooth as my OnePlus one.

There is no evidence that I know of that suggests Samsung is aware of this. Also, I'm not even sure there are such dramatic differences between Lollipop and Marshmallow in terms of performance improvements. All I've read about are fingerprints integrated more deeply in the OS, Doze and a handful of other new features.
[Galaxy Note5 General] Willyman:
I take back what I said above! There appears to be a big improvement in the scrolling behaviour, at least at first sight using the flashed Marshmallow rom!
