Please help: My N9600 dual sim is screen lagging - Samsung Galaxy Note 9 Questions & Answers

Hello dear members,
Here is my dilemma:
Bought the Chinese N9600 variant dual sim Note 9 and I am experiencing some serious lag/stutter on the screen
when I close any apps, i.e. Messaging, Contacts, Whatsapp, Phone Dialer etc..., only when I set the screen resolution
to WQHD 1440. At FHD 1080 everything seems to be snappy. When I changed the battery mode to Performance I saw a little
improvement, but the stutter is still there. I hear from different owners of Note 9 that they are not experiencing
the lag, and I myself tested different Note 9s from friends and everything seems very fluid at WQHD right out of the box
without changing any settings. The funny thing is it got worse after PIE Update.
Done Factory Reset about 6 times, tried installing the apps one by one to see if a particular app was introducing the
lag, cleaned the system partition cache but nothing helped. Right now my phone has very minimal apps installed
and no Widgets. Went to a Samsung Service Center in Canada everything checks out, both hardware and software.
Is anyone else experiencing some serious lags at WQHD? Any thoughts? Solutions? At this point throwing my phone
out the window has crossed my mind.
PS forgot to mention I am using it in Canada on Fido Network and I got the PIE update a few days ago OTA.

[Q] Two notes - one smooth , one laggy is this possible

I purchased a note from amazon last week . when the phone arrived the screen had the banding issue so I re ordered a replacement
The smoothness of the banded phone was really good - yes the home screens lagged a little however the new phone which arrived today has a real lag .. it doesnt seem fluid when moving between home screens , the apps tray does seem smooth ..... i have HD widgets on my home screen, my email app and message app widgets and couple of contacts on direct dial
It just doesnt seem fluid as it should be with a dual core 1.4 .....
Is it possible for the processor to be faulty or am I worrying about something which will be changed on ICS .... I know I am looking hard for faults as I want the perfect handset at the price ive paid ...
The screen on this one is perfect as far as I can tell (ive decided some apps have the banding not the screen) I have decided its perfect because a HD film is out of this world .
What do you think .. if im happy with the screen and everything else .. is the lag something which will go over time with firmware update
Thanks in advance
HD widgets make the screen transition laggy(only on that page).. just try removing it./..
I'd say its fully possible with faulty hardware similair to pc with fault ram. Me and My friend have the same issue, my note is fully tweaked and he is on stock rom NO tweaks. He never experiences the 1-3 lag that i've described in my topic so yes I think there are faulty units, since In my case even when reverting to stock the 1-3sec lag is there, yawn!
Were they both running the same firmware?
Did you upgrade your Firmware OTA (Settings -> Phone Info -> Software Update)? If no, do so. The current firmware is WAY more responsive.
Its probably possible everyone goes on about lag here but mine is smooth always, the only time it lags is when I first get on the homescreen after boot up after a couple of seconds though the lag disappears.
There are a lot of lag complaints on the note, Im yet to actually see one though so Im guessing it could be a defective part.. why not try to hardreset the phone and see from there?

Touch issues / Sensitivity issues after Nougat update

Okay so I wanted feedback regarding this whether someone else is experiencing this or not.
I have gradually observed during the last few days that a lot of my touches to click have gone unresponsive in Nougat. Initially it was something that I hadnt quite noticed but slowly the trend became obvious. Now dont get me wrong, this would happen a few times here and there with lollipop and MM as well, but the rate is far higher now on Nougat. Especially when typing on the keyboard this means mis-spelled words, missed letters, and accuracy is far worse now.
Has anyone else observed this or is it just me?
Just got my xcover 4 with nougat installed i have the same issue.
The sensitivity is low and i need to press a bit higher finger force to respond.
Even with sensitivity (glove mode) set to on things get worse.
I'm seeing the same thing. What is strange is that I'll see the button highlight/depress, but no action occurs. This is on multiple apps.
On what device/OS?
Sprint Note 5 on Nougat
Did you try gloves mode? Does it work?
the same for me on 920cd and the same iusse using S pen
I contacted samsung Greece about the existing problem.
I reported the problems me and you guys have and the tech support told me that your problems exist because you did not factory reset the devices before upgrading to nougat.
Anyone tried to contact samsung about the problem?
They dont know anything about it.
facing same issue screen lagging in note 5 sm-n920s also tried custom rom but still lagging in typing and scrolling on facebook
I have the same problem on my xcover 4 here!!
When I run the the touch screen test, touch screen responds well, but when I want to write a message or to scroll the home screen Its very annoying. It looks like software problem.
please help
Hi guys.
I have 2nd piece of Xcover 4 SM-G390F (first was change by seller for new one) and had the same problem. First 2-3 days all work perfect.. I have installed my applications, work perfect for two days, but after this... --After wake, display react only in centre area, 1 centimeter from display border no reaction or react on xxx touch. After few seconds (20-30) display react on full range, but with lags... So... I go for support to Samsung official at CZE.
Support tells me, that they don't know about this problem, that I'm 1st who has this problem... And some other bull... about unofficial sell and any other. So I post them IMEI and they let me know, if my distribution is official or not, and we'll see what next. They recomend me to go to service center, where somebody looks on my SM. So I see tomorrow.
ROM - official Android 7 Nougat from start using (not updated from other version)
Deleting apps - no effect
Safe mode - no effect
Factory reset - no effect
Apps to calibrate screen - no effect

Note Taking Lag with s-pen?

I just got the Note9 512 8gb version. When taking notes I get an annoying lag or delay. Is this normal? I thought it would be super smoother. Also the delay time varies a bit too. Its like sometimes letters I write show up late and I'm already on the next letter. You have this happening? Especially when writing fast
I rebooted and cleared cache in storage maintenance. Thanks for feedback.
EDIT: I FOUND OUT THE ISSUE - GO TO PAGE 2
On the Note8, there was ZERO lag when writing. I write constantly on here and have never seen lag once. So I doubt that's normal on the Note9.

Damn! I mean Good! I mean damn my phone has lag taking handwritten notes :/ I wonder if its another feature that is turned on or another app interfering. But I havent installed much....
I've taken loads of notes in the week or so that I've had the Note 9 and never noticed any sort of lag whatsoever.

I did online support with Samsung.... we factory reset and I believe it fixed the problem. I still have to do a full restore though... hope it doesn't come back!

After my restore... the lag is back. ITs back :/ and I'm not sure if changing phones would help
It is not lag. It is called input latency. And the people claiming there is no latency on note 8 or 9 need to watch closer and see some demos of input latency. I skipped the Note 8 for this among other reasons. If I had to guess the input latency is about 15ms ±5ms. Pretty damn good. If you write fast you're going to notice it more.
Lag, latency, stuttering and frame drops are all completely different things. People are just using adjectives to describe their experience when things are more technical. It is kind of like many people don't understand lower case and upper case B's when talking about megabits and megabytes per second or giga-. Latency is a big deal for online gaming and steam link. That is why the hard core gamers will use Ethernet instead of wifi for gaming and the same for steam link. That 40-100ms or even more saved is a huge deal. It is obvious when you use steam link over WiFi and then go to Ethernet.
As far as the OP I don't know if you have a legitimate case of input latency or your expectations are too high. As I mentioned there are many videos to show input latency. I believe Microsoft has one of the better ones with a demonstration board that can dial in the input latency demonstrating over 100ms, ~50, 10 and 1ms. When under 10ms starts happening on every phone is when it really becomes game changing for not just flagship owners but people across the world that use these marvellous mobile devices. iOS used to much smoother for years than Android but input latency was still a thing. Now iOS and Android are competing head to head as far as latency, scrolling, frame drops and lag. It has become something Apple could not ignore anymore even though their SOC has been more powerful than Qualcomm and Samsung the last couple of years. All that power and it was dropping frames, scrolling janky, and input latency was noticeable despite their claims. Features have been put aside for iOS12 and focus has been put on performance. As you can see Samsung did this with Oreo and the Note9. The note 4 input latency was horrible but the phone was still ahead of it's time.

After we did the factory reset it worked perfect, I could not replicate the delay I am complaining about.... if it was what you are saying, wouldn't I see it all the time? I could not recreate the issue at first, only till after I did a restore of my data did the problem come back. If I handwrite... sometimes its a one letter delay.. or even 2 letters will appear after I write or once in a while 4 letters!! so that is like a stutter.
Have you tried clearing the cache data in the storage maintenance menu? That might help
Note 9 factory software is lagging much than s9+.
Hope samsung will resolve lag issues soon

Yea I tried that and also factory reset. Like I said... after reset I couldn't recreate the problem until I restored some of my backup. OR it may only seem to happen in certain note views... as far as I know there are 2 view screens ... it seems to have less 'lag' in creating new note right away. The edit screen with the default lines on the "paper" the view is a bit different and that is where I get the most lag it seems when I write.
So I just got my replacement. Before I did my restore I tried notes. I was SOOOOO relieved as note writing was perfect... no lag.. no delay.. I could write smooth.. awesome!!!! BUT . I did my restore and my problem is back! What the hell is going on? ^%$ . So now I will factory reset, AGAIN, and just build up my phone without a restore :/ and see if I can get around this problem. Will report back.

I found the problem! And reported it to Samsung. Can you recreate this issue on your phones?
So my backup settings had option for Accessibility > Vision > Magnification > Triple Tap Screen to magnify if this is turned on = I get wicked lag while writing notes. Its not that I am triple tapping getting a bigger size either. Just something with the gestures while writing is interfering with Accessibility Magnification settings. Turn the setting off and all is good.
Can anybody confirm?
Samsung 9 is not available in my country right now. Hope this will available soon, I am waiting :cyclops::cyclops::cyclops:

The problem is that you are importing your notes made using the old S Note app onto the new Samsung Notes app. There appears to be a compatibility issue between the two. Which Samsung never addressed.

No I fixed my particular problem ! I explained above. It has to do with the Accessibility > vision > tripple tap magnifier interferes with notes if turn on. Doesn't matter if its an old note app or new note being created. I thought something like you at first, but no my issue is this bug. And it is a bug. Turn on "Triple Tap" on your phone and create notes and report back to me how crappy it feels .

Just tried it. I can't seem to replicate your issue

Note 9 you turned on triple tap magnifying? Your new notes are all smooth? Weird I have 2 notes in front of me today .. both factory reset and I can recreate the issue. Both are the 8 GB 512 version unlocked us phone.

Guess it must be a bug that affects the US variant. As I am using my company's Exynos variant and everything is super smooth.
I just recreated the issue on my new S4 I got from Korea. So that is 3 devices I tested on. Try turning on tripple tap mag. Then write a note writing fast.. example try. The word THIS lot. The IS will ghost and delay thus screwing up brain to write neater etc.

Anyone else having these issues ??

I have just had to factory reset my phone after just 3 months of use. Coming from being a heavy nexus and pixel user I always noticed little Samsung animation stutters when navigating the UI... Even open and closing the app drawer stutters when swiping up and down which I'm very surprised about for a phone with this amount of power and all the praise it gets from reviews. Don't get me wrong the phone is still snappy but I'm very sensitive to animation frame drops.
As time has gone on I've noticed really severe frame drops even when unlocking the phone to the home screen using the finger print scanner and even using the finger print scanner started to not work and could take 2 or 3 presses before it would unlock the phone and even then it would lag and take a few seconds to actually open the phone once it had recognised the fingerprint and made the unlock sound
So far since resetting it has been better but I wouldn't want to keep resetting every few months cos Samsung can't make a decent UI. Has anyone else experienced these types of issues or am I just unlucky???
I have the phone scheduled to auto reset once a week to keep it fresh but that obviously didn't help.
I turn off animations. Also, get off the Samsung Experience launcher, which helps a lot.
I'm sensitive to that stuff too and this helps it all go away.

Thanks I'll try using Nova launcher and see if that helps.
My fingerprint scanner gets laggy sometimes too. It's odd. Because it never happened on my Note 8.
I've got a 512GB Note 9 coming in the mail (hopefully tomorrow), so I'll see how the 8GB vs my current 6GB Note 9 does.

I've got the 8gb one. Never had a laggy fingerprint scanner. Weird!
I have the AT&T version with unlocked firmware installed and have noticed no lag using stock launcher.

My 512GB Note 9 didn't arrive today. It got misdirected in the mail...again. Apparently, it has left the Kansas City distribution center three different times in the last 12 hours, but hasn't actually gone anywhere.

LOL! Maybe! It finally arrived at the local post office last night, but it's not out for delivery yet. Nor is it showing as expected to be delivered today. Usually by this time in the morning, my packages are showing out for delivery. It's all so weird.
I must admit my Samsung note 9 is edging towards 1 of my worst phone purchases.
Fingerprint sensor isn't as great as what I thought it would be nor is the biometrics unlock.
Wifi calling has pretty much stopped working since a few updates back. On EE UK.
Only get wifi calling with volte turned off.
Constantly missing emails and texts for some reason I dont seem to get notifications come through. So I would open my text messages app and notice texts from hours earlier which didnt notify me in any way same with emails which didnt come through but yet sat unread in my emails app.
Definitely not as smooth as my previous Oneplus 5 cant see how because it has Samsung ui on top it should be expected.
The S**t thing is I bought it on the upgrade programme so paying monthly.

Wow. Sounds like you got a bad device. My fingerprint sensor gets laggy sometimes,. Ut I don't have any of those other issues. Maybe try a factory reset?

I don't know then. I'm sorry you've had so many issues. The Note 9 has been a great device for me.

Question Random lag after update on QHD 120Hz

Hello,
I've updated to coloros12 and i wasn't able to change the wallpaper of the phone, so, I decided to do a factory reset
After 2 factory resets, (one trought the recovery and other from the menu) I've found that phone have some lag during some animations, like swiping to show all apps, navigating trought apps, also on twitter when you scroll on the main feed, specially when i open twitter after many hours it lags as hell (like an old slow phone)
so, when i got the phone a month ago it was very fluid but now i don't know if something got broken or if it's a software issue
All this happens having QHD enabled and 120Hz
Does anyone have the same issue? is this a bug? is there a dffefrent way to do a new factory reset?
thanks for all your repplies
Not sure if my phone has the same issue or similar. After the update to android 12 when the phone is set to Dark Mode and going through the pictures in Gallery the screen lights up and it feels like is flickering, also feels a bit slower. When in light mode everything seems to be working fine. Is no difference in FHD+ or QHD and at 120Hz
I'll open another thread for this.
Edit: The problem seems to be isolated and is only happening when using the Gallery app at 120Hz, the screen flickering starts and the gallery is very slow. I've installed another gallery app and seems to be working fine.
