[Q] New Lag Problem

I've been using my Note for a long time without any of the issues I have read about. Until now. This past week there were several updates to applications, including one that allows apps to send things to OneNote, which I had been waiting on for a while.
Then I was using Mazec3 inside NoteAnytime and while I was writing, things just froze up momentarily and my handwriting was all screwed up. I suspected the app, so I switched back to the Samsung pen input, but I had the same issue.
A device reset seemed to fix it mostly, but I have noticed that while playing CandyCrush, I get a momentary freeze.
The original hesitation seemed to be when the device was converting the handwriting to text (or to suggested words) and adding the CandyCrush issue in seems to suggest a bogged down processor.
Has anyone else had this issue and/or know how to fix it?
Thanks,
PNCguy

Mine is doing the same thing. My google keyboard keeps crashing. I uninstalled it and it's been performing a lot better.

Same here. Especially noticeable during video playback. I watch videos all the time on my note and this just started the other day. Thought it had something to do with my SD card, so I put the file on internal memory. Same issues, any ideas?

Not impressed with lag

I'm not sure what is causing lag, but my Note 4 had enough of it to be concerned.
Sending SMS and messages via hangouts is brutally slow, just as scrolling through Google Now and within the eBay application.
I have a little bit of stutter in touchwiz, but that isn't near as bad as the app stutter. Wondering if this is something to be concerned with.

only reports of lag I have seen are @

I have not seen any myself, this thing powers through anything I have done so far.

Same here, my phone runs butter smooth with animations set at .5 and forcing GPU rendering. Gotta love that Adreno 420
OP might have a bad device. Try replacing it to see if that fixes the problem. Very few people have reported lag and it seems to be no more then any other device.

I want to point out that I had the same issues you mentioned. I went ahead and performed a factory reset since I just got the phone and I hadn't done much to it. It solved my problem and I'm not getting any more app stutter from sending messages through hangouts.
It happens, man. Initial setup of the phone could go wrong, especially when you load on a ton of apps at once. Might not have been your fault; it could've been the devil that loaded all that carrier bloatware on it.

No lag here either, I've been running a media converter on it 24 hours a day for the past few days to change a lot of my formats to mp4s from mkvs and even with that running in the background, with encoding being one of the more CPU processing hungry things you can do, I can play GTA:SA on it without issues.

I was actually lagging pretty bad past 2 days. I enabled ART and let it go for a day thinking it would get better. I restarted it the second day hoping it would help. Finally disabled it an hour ago and its working as expected... Guess there is no real point. I'll just hope we get 5.0 before the years over.

It was good for me before, but wowee. Thank you for the tip.
I feel the power!! So much of a difference that makes

Yeah buttery smooth here. I've disabled all the ATT apps via managing applications and ALWAYS use Rechild Task Killer - by far one of the best app killers I have used over the years since Tmobile G1, Note 1, Note 2, Note 3, and now Note 4. It helps despite what anyone may think.
Also, as other have mentioned, tap your build number 7 times to enable Developer Options Menu in Settings - General. From there, you can disable animation transitions - I always set all mine to 0/No animation because I don't need animations and that speeds things up a lot.
All my texts/MMS are fast along with browsing and internet - HUGE difference compared to the Note 3 (everyone was right- that phone had the worst WIFI imaginable - I was rooted and had the same setup as I do now on the Note 4). I have my MOTO 360 connected with bluetooth always on. I use Textra as my main sms/mms app. I'm really happy - battery life is excellent compared to my Note 3 because Android Wear eats a lot. I also have 1W weather widget on refreshing every hour. I have location on power saving mode so only Data and Wifi pinpoint my location instead of GPS (this is just common sense - GPS kills your battery so don't choose the TOP high performance option).

Wow, what a huge difference. Thanks!

thats odd because I dont get any lag. The only thing I noticed is once in a while, when opening Hangouts, the GUI gets stuck at a blank screen and I have to back out and enter in again. The other issue I noticed, which doesnt happen often, is that the network gets stuck in a certain speed (i.e. 4G or whatever), when I know I should be getting LTE service. If I toggle airplane mode, it switches to LTE and works flawlessly after that. Its almost as if the modem has a hard time switching networks.

Well, it looks like my Hangout lags is back after I got a ton of auto updates today. I probably shouldn't have left auto-update enabled. There's probably an incompatibility with one of the apps so I'm going to hunt it down. Other than that, the rest of the phone is quite smooth.

UPDATE: The problem is clearly the hangouts update itself. I uninstalled the update and disabled automatic updates. It's running smoothly again.
So the problem with hangouts appears to be the most recent update. Uninstall it and you'll run off of the stock version that shipped with the device. until they've fixed the problems.
The problematic build is 2.4.78234730 (Oct 22, 2014).

And no problems with sending messages?
I've cycled installing and uninstalling it a few times to verify that it was indeed the problematic version for me. It could very well be an incompatibility issue still, but I'm not experiencing problems with other apps... aside from Instagram being awfully choppy when cropping photos for upload.

touchwiz always lags. the lg g3 has significant lag to.

I did a factory wipe, disabled all the bloatware i could, forced gpu rendering and changed animations to 0.5x and honestly, it ive been good to go. i did all this to my dads note 4 this morning as well but he said he hadnt experienced any issues yet with everything kept stock

GPU rendering is pointless. I tested the other day. The speed was exactly the same for opening and closing apps, etc. The drawback, if you have flash video enabled and watch any video, shows, movies, etc. - it will be laggy/choppy with this option enabled.

Might need a master reset. I just purchased this phone yesterday. The first phone they gave me reset itself almost 30 times on its own despite me master resetting like 5 times. After the second master reset I didn't load any apps and the issue still persisted. Went back and had them give me a new one. All is well now.

might have spoken too soon. Hangouts works fine after the latest update but i do notice a second or two lag when trying to open the keyboard or open a chat. Its not enough to really complain but it is noticeable.

Noob quesion.. Can someone please direct me to where I go to force GPU rendering on the Note 4? I can't find then setting anywhere. I've been out of the Android game for a while so I greatly appreciate the help. Really like this phone, but the lag on even simple tasks like Facebook scrolling is leaving much to be desired.
(Disregard finally found out how to enable Dev Options.. Man I got a lot of catching up to do.)

Music apps getting killed in the background

Hi all,
Enjoying my Samsung Galaxy Note7 for the most part, but I am experiencing one extremely annoying issue.
I play music on my phone a lot, all of it streaming from either Apple Music or Pandora. On the Huawei Nexus 6P both apps work flawlessly (on both MM and N Preview), never cutting out whether in the foreground, background, screen off, whatever.
On the Note7 the apps seem to be getting killed or otherwise stopped for no apparent reason, even if they are the only apps in the switcher.
Anyone else experiencing issues like this? It seems to be worse with Apple Music, but as I say it has worked flawlessly for me on the Nexus 6P (as well as a few other recent Android devices for that matter).
So far searches have proved fruitless.
Thanks, Mitchell

Yup, it has happened to me a few times also when using Spotify. App doesn't close, but randomly stops playing my music and restarts the song when I tab back in to press play. Coming from an iPhone, I've never experienced this issue.

Sounds like the same issue. If I reopen Apple Music for example, the app opens immediately where it was, but the playback bar at the bottom is gone. When I click play on the stream I was listening to it restarts, same as you.
Similarly, coming from the iPhone (or even other Android devices), its frustrating to no end.

Are you all on Snapdragon or Exynos? My Snapdragon Note7 has the opposite problem. Music apps won't kill when I want them to and when I walk back in to range and my Gear reconnects from 3G to BT Pandora starts playing. Even though it shouldn't. My office isn't amused. I bounce between Pandora, Play Music, and Slacker and never had any of the issues you're describing. And I use them through Android Auto and would know if they weren't picking up from where I last left them.

I've got a Exynos N930F

Remove the apps that are being killed from the "App power monitor" under Device Maintenance - Battery.
You have to scroll down and click on the "Unmonitored Apps" and add the apps you want.

Thanks for the suggestion, I've just added them to the list and will see how it goes!
Interestingly, FB Messenger, WhatsApp and Android Auto were already in the list.

Sadly it didn't work, music stopped again this morning after just a few minutes

Audio slightly out of sync when using streaming video apps

Hello to everyone!
I just purchased today the Samsung Galaxy Tab s4, and coming from the Nexus 10 I was astonished by the speed of the device ?
The only thing that bothers me a lot is that whenever I try to watch YouTube, Vimeo, Netflix, Facebook videos or any other streaming video app, the audio is out of sync slightly from the video. This happens only when using the tablet speakers or wired headphones, but not with Bluetooth headphones. On Bluetooth the audio sync if perfect. Also playing locally stored files on the tablet itself, the audio sync is perfect regardless of using speakers, wired or Bluetooth headphones.
I've searched and tried everything I could find (latest update, clear app cache, restarted multiple times, disabled stock anti-virus, force gpu rendering on developer options) and nothing works!!
Has someone else had these issues? Can someone please help me, is there any suggestions? Maybe an app or setting for audio latency adjustment? I'm willing to flash a custom rom on the device (been using LineageOS on my Nexus 10) but can't find anything for Galaxy tab s4.
Thank you!

Any answer someone?

I'm having the same problem, would like to see a solution, because it drives me crazy!!!!

Just replying to say that I have the same issue and it is beyond irritating!

I haven't noticed this at all

No issues here. All in perfect sync.

I already contacted my countries Samsung support about this issue. They said they will investigate it and contact me.
I hope this can be fixed because I basically can't watch videos with that delay.
Also I have an audio latency while watching stock videos stored in the tablets memory.

I'm sending my tablet for service tomorrow, but I've read a lot of horror stories... I hope that I don't end up in one of them

damn, I wonder If I should do the same... I wonder how many people just do not notice it, because delay is very small...

Just want to add to the list, noticed the same and posted on a german forum - but no one even responded there. Maybe no one realizes the issue.
It is best described, as if you have connected bluetooth headphones, which always have a slight delay when watching video. It's not much, maybe 0,3/0,5 seconds.
Please keep us informed about what samsung did and wether the issue could be resolved.

Yep me too
Is subtle, but is there
So I am pretty sure is a software issue
Or many many units are wrong....

I opened yesterday a same topic on Samsung's official forums.
ice0cold, Dedusa23, q173242 and hardpike, if you can write on that thread also maybe it is helpful, someone may see it from Samsung. You can find the link below
https://eu.community.samsung.com/t5...g-streaming/m-p/694759/highlight/false#M25430

I have to say that I did notice this short after buying it.
But yesterday I checked and now seems ok
I did check amazon, netfliz and one movie with mx player
All good now

what about Youtube? I'm still having the same delay.

I thinkni still seeing a slight voice delay

I'm in the USA and have same issue...
I bought my tab S4 as an open box from Best Buy. Audio is slightly out of sync, behind video in most apps. YouTube is the worst, but in Amazon Prime Video it seems perfectly in sync. I went to a different Best Buy and looked at the demo model. Same sync issue as mine! Next time I visit the store I bought it from I will check their demo model.
Hopefully it's not a hardware issue because Amazon works fine. Could be some underlying Android video API causing the problem....one Amazon doesn't use?

Recent update.
I took it to a Samsung service point and they are deniyng the problem.. They say they don't see anything wrong hardware wise and that the delay is so slight that is barely noticeable by them.. I'm going to wait a couple of months and if nothing changes with a new firmware update I'm going to sell it and get a new one. Samsung honestly I'm very pissed with you and your representatives...

I just noticed it again, when watching Netflix.
I haven't noticed the issue in other applications. Will have a look.
My former tablet is the first Tab S 10.1 and this was never an issue.
I will try using BT-Headphones, wich i did not yet try.
Also, I will look at different Apps, but Netflix is most annoying.
It is probably a good idea to submit an error report to Netflix.

Question Pixel 6 pro screen glitch

Hi, anyone has this issue with pixel 6 pro. It only happens on video from YouTube and very intermittent. Does not happen to the same video. Have not seen it in full screen or on other apps. Very strange bug or is it hardware issue in which case I should get a replacement

I'd suggest to use safemode and see if it still pops up then, in that case I'd contact Google. Of course you could always try a factory reset, but that's a heckload of trouble and wasted hours...

The hard part is that it happens only once a day or so that I struggle to capture it. So I'd probably have to run on safe mode for a long while, I'll see if I can get Google to replace. Cheers

I've never had that, I'd RMA that if I were you!

I definitely had that happen last week when I was watching Youtube! This was after a factory reset too so I wasn't sure what was happening. Same exact thing, lines flashed across the screen just like yours. I have not seen it happen since or perhaps I haven't been watching enough videos on the phone since.
Have you contacted support, and what did they say? I'm kind of scared to contact them with all the outsourcing now and other stories I've been seeing about them not being as helpful as they used to be.

I'm not sure but am wondering the same thing. I was not able to get a hold of Google support but will try after the new year. If the OP can see it happening randomly I bet it is happening randomly for us too but we haven't caught it again. It looks like those old CRT TV's. I unfortunately was not able to get screen recorder open in time to capture when it was happening.

There is no need to record your screen. you can send google the op recording
I hope google will fix this phone.. I guess that is what you get for being a Tensor early adopter.

I just had this happen too for the first time, happened to quickly to get any recording of it. Also on YouTube as I was adding a video to my watch later. Are you using Vanced by any chance? Maybe it's just the software glitch with that?! Hope there's no hardware fault going on here...

I am using the regular Youtube app since I pay for premium. I don't think its related to any app as the OP said it also happened on other videos.

Also have this happen to me somewhat often (once or twice a day), but it's only ever in the youtube app. I'm using the YouTube vanced app and It's never happened in any other app.

Interesting.....let's hope a fix is on it's way at some point...

Have you guys noticed a graphical glitch in Google photos? When in landscape and the video is paused and you scroll up from the bottom of the screen for your settings, a glitch appears!
It was first mentioned in Reddit.

I've had the same thing, but it appears at the bottom of the screen (it's happened a few times, maybe 5 or 6) - and for mine it was about an inch high. It was really odd - never seen a glitch like that before. usually you can tell if it's the display or software but this was very similar to op's - and it stayed for like 10 seconds. using Brave Browser, not watching a video (pixel 6 pro on december build)

YES YES YES! Thank you for the post, OP!
This wasn't an issue till about five days ago and it only occurs in the YouTube application! It's difficult to reproduce, but usually having a video running, opening the comments section then successively minimizing and maximizing the video (in Portrait mode) can trigger this error.
I suspect it has something to do with a change in refresh rate, since this particular change causes just that.
It's not annoying to the point I have considered turning the phone back, but it's mildly concerning especially since the first time it occurs, you're unsure whether it's a hardware or software issue.

Same here with YouTube Vanced in the exact same Spot, never seen in another app

Try newpipe instead. Hint: no ads
