[Q] lags, high cpu and assorted sluggishness

I am using CMYLXGO's NAND stock Desire HD build. Its great. However, I am having so many lag issues. I seem to be one of the few that is experiencing this with the build so i turn to some of you to see if you have had similar issues with your phones.
Problems:
1. when auto populating apps (like using installer, uninstaller, managing applications in the system tab) the phone will take forever to pull up all the apps , the screen will cut off (because the screen times out) and when I hit the home button or any button to cut the phone back on it stays black.
2. every action makes the cpu run high. adding a widget to the home screen (apps populating issue again), changing screens really fast and other assorted minor processed.
I have stopped auto sync
I do not use auto rotate any more
I do not have any rogue processes for the most part
I don't understand why I seem to have these lag issues. Everyone else talks about how fast and fluid the build is. I am under the impression that with the build NOT being run from the memory card NAND would add to speed. This is not happening for me. If anyone has any idea why this is happening. I am convinced it is something on my end but I don't know where to start. I am open to suggestions.
I have 2.15 radio, 16 gig class 2 memory card.

Hmmm, not sure but have you tried another ROM similar to see if it does the same? You can also go into MAGLDR and wipe dalvik cache. I used this ROM and all was good for me. I have sense been using this one which is also working very well.
http://forum.xda-developers.com/showthread.php?t=976384&page=1

every version of this build has been tried. That is the part that gets me. differnt kernels don't help either. i have even used SetCPU and overcloced to try and get through some of the lag. it works, but it is only when I play games not when I need to perform uninstall or widget selection for the home pages. I use SeePU which is ususally shows my cpu strain in the bright orange (for high use). most of my processes/actions raise the cpu use to high levels. I never really operate in a green (or low) usage level no matter what the action is. I would really like to capitalize on the speed NAND is supposed to offer.

Personally I would try something else (a totally different ROM) and see if you are still getting the same results, maybe even revert back to a windows mobile rom just to see if you are still getting the hang up. Last option would be to restore your phone to stock and start over, reinstall HSPL 2.08 new radio, etc...etc...

do you use an app killer?

yeah. but i did not at first. however, it is needed to stop some of the rogue processes. android.process.acore comes to mind.

I personally think this is one of the most stable builds around. I would rarely experience any lag, and if I did it would only last for seconds.

Believe me, I know. Everything is working in his build. GPS, MMS, easy to install - the works. This is why i really want this to work properly so I can use it, without the hiccups, as my daily build. It has to be something with my phone but I can't figure out what it is yet....

On Cmylxgo's build, the first time I loaded it, I had the laggy and unresponsiveness you described for the same reasons. What I found is that rebooting the system to off/on a couple of times when I first loaded the build, addressed the first initial lag and unresponsiveness. After doing a couple of reboots, I found the build as smooth as everyone says it is. I am now trying the GL Core v11 kernel and it gives an extra 300 pts to the Quadrant Score and seems to be a bit quicker than the Rafpigna 1.8 kernel that comes with the build. Also, standby battery drain seems to be a bit better with the hourly peaks at half what I see with Rafpigna. If rebooting a couple of times doesn't do it for you, I know trying another build which may not have all the bells and whistles as Cmylxgo, but it is worth a try to see if it makes a difference. For me at least Cmylxgo's stock Desire (HD)2 build is much faster and smoother than any of the MDJ SD builds I was using.

(xoom 2) XOOM 2 10.1 Freezing & Reboots – A SOLUTION!

I just wanted to share with you my recent issue & solution to the XOOM 2 rebooting issue.
Now to give you an overview of my situation, I purchased the XOOM 2 10.1 UK back in January 2012.
I use it almost every single day. No surprises I was getting random screen freezing followed by reboots every single day. Most days twice!
Now I was hoping that when the update happen back around 2 months ago that it would solve this issue. It never.
In fact my freezing & reboots were happening more frequent.
Basically within 5-10 mins of using the Xoom2 it would reboot.
Some days I just wished I could throw the dam thing through the wall.
I rooted using Dan’s method. The only method. & tried various ways to solve the issue.
NOTHING worked.
In fact, I was convinced that my rooting & installing things that should not be there was making the reboots worse.
So I cleaned up my Xoom 2, went into recovery, wiped cache & cleaned data & rebooted.
This still did not work.
Then I tried task managers, cache cleaners & even paid for that system panel app that logs all apps & usage.
Nothing worked; I was still getting the reboots. Everyday.
So after looking over many Xoom 2 forums & with many issues and complaints about this issue, I was close to selling & getting an iPad.
I was convinced it was hardware.
Then I tried this way:
1. I rooted.
2. I installed ADW Launcher & made default.
3. I installed SetCPU
4. I installed Titanium Backup
5. I froze the stock ‘launcher’ – (whatever you do – do not un-install any app, you CANNOT update Xoom if you do)
6. I changed CPU from ‘hotplugmoto’ to ‘performance’ 1200min 1200max
(I know you might think this uses lots of battery but I found not)
7. Set up setCPU profile for ‘screen off’ I use ‘on demand / 300 to 600’
Battery over night on this setting did not go down by 1%
8. Rebooted.
After 4 days of constant use & trying so hard to get the Xoom to freeze & reboot – I can’t.
This method works.
I have surfed using ‘Firefox’ while using ‘Currents’ while using ‘Google+’ while downloading files and steaming music via ‘Google Music’. I have open every single app & been quickly switching between them all trying to over load the system.
Nothing will freeze or reboot my XOOM 2.
What I can get from this is that the Xoom 2 works perfectly.
With the high CPU set, it is so fluid and lag free. It works almost perfectly now. It also means the hardware is absolutely fine.
Maybe with newer firmware updates in the future this will be sorted naturally.
I makes me think something with the high CPU means a bug in the processing won’t make the Xoom freeze & reboot.
Until then this method works for me and I can’t see why it won’t work for you.
If you are having this issue I hope this helps.

I messaged you on the Motorola Forums, but I think they may take it down since they don't like talks about rooting.
But thanks for posting this, I will give it a shot.
When you changed to performance 1200 min/1200 max - I'm guessing you also checked set on boot? right?

Yes i ticked set on boot. Make sure you have a screen off profile otherwise it will be running at max all the time.
Hope it works for you.

Hi,
I froze some bloat before and uninstalled flash 10.3 cause flash streaming online videos didn't work 4 me (neither 10,3 or 11,x), then installed flash 10.2 and all starts to work ok but still 2 or 3 reboots for week.
Also seems that "memory booster" app helps when some apps starts to freeze and u can finish em and free some mem.
So now i'm trying setcpu and then i will do launcher trick
Thx a lot!

Vanpeebles, Did you switch launchers because you think it will help the reboots? or because of personal preference?

List of frozen apps
List of frozen apps 2 months ago without issues:
App used: Ultimate Backup
Amazon Kindle (I dont use it)
Citrix Receiver
Drippler Motorola DROID Xyboard 8.2
Drive
Fuze Meeting
Google+
GoToMeeting
Servicios de estadisticas de dispositivo ("Device statistics Services")
Twonky
Good luck everybody!
Now i'm not expecting ICS, this is working almost perfect. Let's see setcpu improve.

It does seem that the source of the freezing/reboots is the Motorola Launcher. Since I switched to Go Launcher HD I've definitely seen less freezes.

Hi
I switched launcher on personal preference but to be fair I have had no freezes now for 5 days
So I'm not messing now if it ain't broke.
The reason is I did this is I read 1 post on another forum that someone changed launcher &, this helped him.
So wether launcher or high cpu I'm not bothered
To finally have a working tablet is such a huge relief!

Thank Vanpeebles,
I did everything you said and now hoping for the best!
Either way, I'm loving ADWLauncher Ex..... sooo fast and snappy!

Thanks my Xoom 2 is running great again!
Also add this warning. Do NOT remove the Launcher2 app if you do then your Xoom 2 will never boot again and the is no current way to fix this because of the locked bootloader.

That's my question, why do you even need to freeze the stock launcher if you've set adwlauncher as the default.. like what's the point of that step of freezing the stock launcher, it shouldn't impact performance.

No he is right, because the stock launcher takes a big bite out of your RAM around 100MB. And even if you do have another launcher running that stock launcher always seems to be in the background on my tablet.

Yeah but won't freezing the launcher (or changing its name to launcher2.apk.bak) cause problems if your tablet faces a failure and the adwlauncher crashes?
EDIT: I guess titanium backup unfreezes apps if you do a wipe so the best option is to freeze the stock launcher (NOT uninstall it and NOT rename it)
Sent from my Motorola Droid Xyboard 10.1 with Verizon 4G LTE

Over 1 week now and not 1 reboot.
I can't answer these questions on the launcher?
All I know is this works for me, I have had not 1 freeze or reboot, so the stock launcher can stay frozen.
(it may have absolutely nothing to do with it, but I really don't care)

Hi after several days over GO Laucher EX (or HD "Tablet version but less customizable") with Setcpu 1200 1200 performance and etc....
only 1 reboot when several web pages were opened on stock browser with flash videos etc.
I've noticed that now when apps stops to work it goes back to home instead of reboot except that time.
Almost no free ram and that's seems to be the clue..Stock launcher doesn´t free enought memory
And battery drains suddenly stopped.
Super happy man . More fluid launcher, more customizable, and also wifi starts to work better when comes back from sleeping
Thanks for not to give up!

Have to say... this solution seems to be working very well. I'm running set CPU in conjunction with auto memory manager set to "aggressive" and AdwLauncher Ex!
Using many apps that in the past would give me reboots, but now they are working flawlessly.
Thank you very much for this awesome contribution!

I'm Xoom 1 user and also having annoying reboots you described here. Most of all it happens when watching movies or iptv in player.
But isn't setting cpu frequency to 1200min will force cpu run at 1200 not less all the time? It probably may overheat the cpu and sounds dangerous.

When its in use yes, but you also set a second profile to turn down the cpu to a lower value when the screen turns off so you don't drain battery and cause overheating!
So far - I'm running this method without any problems, no noticeable battery drain or extra heat in anyway!

I'm currently running on stock kernel without ability to scale over 1000. Tried to set to performance governor only, but failed and got regular reboot during usage. Will try your method.
Seems to be it's operating system problem. Don't understand why motorola still didn't resolved it, including that fact that problem also present in first Xoom model.

Worked a bit around with your solutions and stabled on the following:
Stock launcher frozen;
SetCPU profiles:
Screen ON/unlocked: Governor OnDemand (1200-800) with Noop Scheduler
Screen OFF: Governor standard hotplug (800-300) with noop scheduler
It looks like moto_hotplug governor doesn't work quite well but I also noticed some glitches on systemui.apk. Whenever you turn your screen on and unlock doesn't show smooth you must turn off screen and try again... if you unlock with a laggy unlocker the whole system will be a mess.
With those setting I'm not having reboots, just some lags here and there; battey, however, lasts much less due to ondemand governor.

XXLRG, German ICS tests with several setups

Hello all,
Following XDA for years, but wasn't posting that much. My apologize for that, trying to give my contributions now
So, to start, hereunder, a sum up of my recent tests over last German ICS rom, Stock XXLRG.
======================
This is the second version of this post, taking in account various comments so far.
Firtsly, this is aimed to share my feelings about my own experience. Hope this could help anyone in anything. Nothing more
Accordingly to Roy_W, I provide which I will call my "test phase" description at the end of post, as simple infos for you to better make your opinion according to your own use. It is not about precise calculations & results, but about comparing the same things.
Hope this helps.
======================
Tests
1. Stock LRG + Stock Kernel, No root
2. Stock LRG + Stock Kernel + Root + remove some samsung apps.
3. Stock LRG + Speedmod 3-7 + remove some samsung apps
4. Stock LRG + CF-Root LRG + remove some samsung apps.
Impressions
1. In my opinion, do not use this setup. Rom feels very laggy, many little freeze here and there but the must annoying is the battery drain and heat while wifi download.
I think this is due to screen ON + heavy download (1GB+, games like Max Payne or Nova)
Pen is not well reponsive also.
Note : Except in test 3, there should be no difference with pen responsiveness between 1,2 and 3. but that was the case to me. Dunno why ^^
2. Starting to feel better, due to the removal of some Samsung apps (Rooting should not have this kind of effect .
Complete list of removed applications at the end of this post.
The phone is more responsive, lesser lags, but other things from test 1 (battery drain, pen responsiveness) remains the same.
3. Very good setup.
Lags are mostly gone, and Pen responsiveness is far better.
Don't know if Speedmod have done some special work for that, or is just due to his overall tweaks. I think it is also related to Samsung S-Suite updates. (look at test 4)
Good battery, feels like it could be better but mostly due to Samsung Roms than kernel. With normal use (sms, few calls, internet, XDA app , new review, some always active sync like Weather, Gmail, Talk, ...), you can easily achieve 2 days (48h) before running out of juice.
Also lesser memory consumption in idle (maybe related to samsung apps that were removed)
But, bluetooth was not working and since it is a must have for me, I needed to go to test 4.
4. Currently in test. Don't have my bluetooth headset with me, so this test will be updated tonight or tomorrow for feedback about battery, bluetooth and other.
So far, overall responsiveness of the phone is ok, but not as good as with Speedmod.
Maybe a placebo ( ), but I always felt that Chainfire's kernel is behaving a little better than stock one even if the only difference is root rights.
Also lesser memory consumption in idle (maybe related to samsung apps that were removed)
Samsung Removed Apps
Always doing this since my GS. It always make the system smoother to me. Can't tell about battery save.
- All Hubs (Reader, Music, ...)
- All apps related to hubs. (Zinio, Press reader, kobo...are examples of ones eating too much storage space).
- the big one : Samsung social Hub (2 apks)
- All stock live wallpaper (storage space eater)
I did not removed the Kies apps, since there were never launched, do not bother me and was having some weird warnings about missing apks while trying.
I advised to keep All Share (which is functionnal and useful for cross hardware connection) and Samsung Apps (but deactivate sync from app settings)
Go also for setting, and deactivate Wifi sync for system updates (About Phone -> System updates).
I did not test NOTECore kernel which has good feedback (3.1 version) because of the bluetooth not working.
Test Phase
Mostly due to my work, I have quitely the same daily use.
- Kernel were flashed the morning, at full charge, with cache/dalvik cache wipe.
- Only 3G, no Wifi/GPS/Blutooth. Auto Brightness, no added/removed apps (except for tests cases above).
- Betterbattery stats, stock battery monitor and Go power master for battery monitoring
- Facebook sync off (for battery save)
- Gmail sync on
- Google+ sync & Instant Upload off (for battery save)
- Weather sync every 4 hours
- Samsung apps sync off (for battery save)
- 1h call
- Gtalk & Whatsapp always connected
- No Flash installed (feels like I should mention this)
- No kills or memory clean
- Fixed wallpaper (for battery save) & lesser lags for screens transitions and opened drawer using NOVA.
What I take into account while making my opinion about battery :
- screen on time versus battery lost for the same period of time. Having used different 720p androphones, I have my own appreciation of that.
For 2000mah full charged batteries in my use with full stock, 2-3h screen on time is really bad, 3-5h should be considered as a good average, 6h+ is a dream.
GNote has a 2500 maH battery, so I have my expectation and maybe that's why I feel bad battery bahaviour when it won't hurt you at all.
- if apps were differently used by me according to their respective impact on battery
- if the basic services of Android are stable towards battery (custom kernels often reduce that )
- any wake locks
- if battery seems not affected by side-effects like mentionned above, then wait for one week of use before stating.
What I take into account while making my opinion about smoothness:
It is about shutters between screens transition, apps transition, feeling about time for the usual apps to be launched, multitasking...nothing more that a simple user feelings
Bests

thanks for the tests... but we prefer the wiping tests... just kidding...

thanks for the info,
which method do you use to remove these apps please ?

Haha..only wipe caches & dalvik from speedmod and CF kernel. I won't take any rosk from stock kernel
For system apps removal, jusy need root and titanium backup
Sent from my GT-N7000 using xda premium

CF-root and stock kernels are identical. No tweaks. Nada. Just root and Clockworkmod recovery.
So, how can the phone lag with stock kernel and be OK with CF-root ???
Placebo ?

Maybe related to the init scripts. For sure the main thing is the root with this kernel but wihin these tests and also for all samsung devices I had with Cf, it were always behaving better.
As I also said, should be related to samsung apps removal, especially the hubs.

So far, overall responsiveness of the phone is ok, but not as good as with Speedmod.
Should be related to various tweaks, and ChainFire always aimed to provide his kernels, with Root and few tweaks.
I had GS, GS2, and CF kernels were always really nice for those looking to a Rom not too far from Stock, but with some performance tweaks and root.
Also lesser memory consumption in idle (also related to samsung apps that were removed)
BUT, having some troubles with NOVA with this setup. Several freezes, and needs to restart the launcher.
I think it is related to root access which needs to be set again coming from Speedmod to CF. Will keep you informed.
Samsung Removed Apps
Always doing this since my GS. It always make the system fly

Got to be honest I disagree with a lot thats written here.
Point 1 :- Why shouldn´t we use this set up??You might have or had problems but a lot of other users don`t,me being one of them.I have had NO laggs,my battery doesn´t heat up that much with WiFi,nothing freezes and the battery life is 100% top,all what you did in Point 3 with usage I get in Point 1 plus a few hours more.
Point 2 :- Once again I disagree,I´ve had no problems what so ever,only rooted for a few extra apps and removed NONE of the Samsung apps,still fast and smooth.Battery life still top,even upto 3 day usage depending on what I´m doing.
Point 3 and 4.....can´t say anything about these points because I won´t go this far,why should I ,everything is super fast,no laggs,a lot less battery drain:good: no need for any mods.(bluetooth also works )
Maybe I´m one of the lucky ones with a good Note :laugh:but this report won`t help me,maybe a few with problems.

Hi I think you don't agree wih my report cause of different perceptions between you and I.
Battery perf is linked to what is acceptable or not for both of us and also from various comparison through many flashes since GB.
And for sure, Linked to the type of use we both have.
It is the same for smoothness. I must say I am very sensible to lags and freezes even milliseconds one For instance, I am so maniac with it that I can detect a lag in a movie while no one noticed around me.
Plus, you can tell about many things to explain mobile OS perf and I will not accept this since I can not accept that a phone running a spec near to a PC ones, suffers such perf issues.
The best example is the smoothness experienced with my nexus with Jellybean against ICS. It is day and night.

Thanks OP for the comparison :victory:

Good initiative from OP for the comparison. Each person use the Note in a different way and will have different results surely from OP. But the main point of this thread was to give us a basic idea on the different setups OP has used. Thanks!

Thanx for making thread with detail study, thogh i can not be agree with many of statements.
Here something i like to say
- There is nothing much difference between test 1 & 2 except you have Root and removed some applications.
So does it mean
*Rooting can improve performance - I dont think so
*Removing application just making space on system ROM, so does making room on system ROM, can increase performance? I dont think so
many application you have removed may not be activated on start, naturally that doesn't have any relation with performance, b'coz it just occupy space not RAM
Now some application which may have enabled on boot, even that gives you temporary extra RAM, As android itself have LMK(low memory killer) which auto kills background applications which is not in used - LRU(least recently used), and when there is enough RAM available, even you exit from applications it remains in background for quike reopening, that is basic android mechanism. So if your aim to remove some application to make available more RAM, it won't be fulfilled, b'coz that application will be replaced by recently used application by users till android system dont sense as RAM is full. (you ca test it - when you have many applications removed, sure you will have much free RAM on boot, but if you look again after 15 min of play with device, it will be again full, same as who dont have remove blotwares, so wat benefits we got by removing those?)
Yes atleast i can say applications which was running in background for some time can consume little juice, but if you believe me, my experience is it can save maximum 3-4%(of full cycle) nothing more than that. But performance? I dont have any logic to believe it.
-I can't comment on test 3, as i have never used any custom kernel, and leaving your opinion untouched.
-Again between 2 and 4
yes you have also not tested much, but somewat if your opinion goes in favor of 4 (as you said in 1&2 responce is not good but in test 4 you saying it is OK) then if i am not wrong chainfire himself said, his kernel is complete stock (minus mmc_erase_cap command +root+su binary+CWM)
so in that case your opinion may not be placebo?
Anyway dear don't feel bad. appreciate your workout, but some points which i said dont favor me to agree completely.
Regards

I think my note must have been XXLRG when I got it but after trying to do some rooting things and bricking it, then finally loading XXLR1 (ICS) It is working great with no lag or freezing what so ever. Also have scored up to 4050 on Quadrant!

I have to agree with this post. I didn't recognize any of the problems stated in the 1st option. I am currently running stock everything after having tried several different combinations of ROMS/Kernels.
There is also a lot of missing information in relation to what exact tests were performed and how they were measured : Whats apps were running at the time, were Wifi / GPS / Power Saving active, what was the state of the battery, how was "lag" measured, what brightness setting was used, Was a good 3g station nearby or was the telephone continually searching for a stronger signal, etc etc etc , The list could go on eternally.
As for anything batttery related, I do not understand how tests can be performed that have not been run over a relatively long period.
There are far too many parameters and options possible, that it would appear that the tests are merely personal interpretation.
I appreciate that you have taken the time and effort to do the testing but I am not convinced that the results can be treated as anything other than one persons thoughts at a given time.
I think that you can only perform these kind of tests when they are performed "identically" on a device that is reset from scratch and that the tests performed are measurable with precise calculation rather than the human eye/sentiment.

Can the results be reproduced, is there any possibility that the results could change, would a third party be able to reproduce the same results ?
Unless of course detailed results and calculations are actually available, in which case it would be very interesting to be able read them.

Hi Dr. Ketan. Again, thanks for your guide, test 1 & 2 was done following it
Do not worry, I won't feel bad about your feedback, as for the previous one.
For sure, I think you and Chainfire knows that type of things better than me (no needs to tell why ^^), just reporting here my feelings over my tests.
*Rooting can improve performance - I dont think so

Think the same.
*Removing application just making space on system ROM, so does making room on system ROM, can increase performance? I dont think so
many application you have removed may not be activated on start, naturally that doesn't have any relation with performance, b'coz it just occupy space not RAM
Now some application which may have enabled on boot, even that gives you temporary extra RAM, As android itself have LMK(low memory killer) which auto kills background applications which is not in used - LRU(least recently used), and when there is enough RAM available, even you exit from applications it remains in background for quike reopening, that is basic android mechanism. So if your aim to remove some application to make available more RAM, it won't be fulfilled, b'coz that application will be replaced by recently used application by users till android system dont sense as RAM is full.

Removing samsung apps does not affect that much battery, but smoothness. I certainly wrongly express myself.
Maybe CF kernel has nothing to do with it since I was always flashing this and removing the hubs (especially the social one) together.
But fore sure, since my galaxy S, even on the S2, and now on the NOTE, doing this does increase system smoothness.
I do not know that much about Android memory system managment, but the first time I've done this was because I was sick about seeing these services running in background, even without ever launching them once and it does consume memory.
Yes atleast i can say applications which was running in background for some time can consume little juice, but if you believe me, my experience is it can save maximum 3-4%(of full cycle) nothing more than that.

I believe you without any problems
You know the deal, 1% here and there...at the end, it saves some battery.
I will update my post, but I can now say that Speedmod provides better battery than Stock/CF, looking at my battery stats for today.

I have to agree with this post. I didn't recognize any of the problems stated in the 1st option. I am currently running stock everything after having tried several different combinations of ROMS/Kernels.
There is also a lot of missing information in relation to what exact tests were performed and how they were measured : Whats apps were running at the time, were Wifi / GPS / Power Saving active, what was the state of the battery, how was "lag" measured, what brightness setting was used, Was a good 3g station nearby or was the telephone continually searching for a stronger signal, etc etc etc , The list could go on eternally.
As for anything batttery related, I do not understand how tests can be performed that have not been run over a relatively long period.
There are far too many parameters and options possible, that it would appear that the tests are merely personal interpretation.
I appreciate that you have taken the time and effort to do the testing but I am not convinced that the results can be treated as anything other than one persons thoughts at a given time.
I think that you can only perform these kind of tests when they are performed "identically" on a device that is reset from scratch and that the tests performed are measurable with precise calculation rather than the human eye/sentiment.

Many good hints in your posts.
For sure, I've made my tests with some knwoledge about that, and trying to be in the same scenario each time.
I will update my post towards the parameters activated and other you stated.

Thanx
yes custom kernel may have improvement, b'coz that is made for that purpose, and we know developer adds some tweaks to improve performance. though i have not tested it, i can be agree on that point. but i have not make review just b'coz i have not used.
Regards.

Phenryth,
I look forward to your results, the basic idea of what you are doing has the potential of becoming a very interesting article.

These are tests without any statistical significance.
So in the end your heart or gut decided.

Everyone has there own view on how their phone should perform. If you are happy with it then there is no need to change it. If not then this guide provides some tips on how to improve it.

To me for the first time ever since the ICS was introduced the 1- setup is absolutely the best I have tried, and I did try all four of them including removing Samsung bloatware.
The touch response is super sensitive, the pen works not just perfect but it also marks when in a diagonal position something never happened before, my one and only complain is the same one since seven months: the lag which comes when opening the Contacts application for the first time ,which is absolute outrageous other than that I am satisfied.

[Q] Note 4: Performance Issue

Hi Guys,
I am a new Note 4 user, I've had note 2 before. Recently I have used Z3, OneplusOne and S5, which in my opinion other than the S5, the phones were smooth and laggieness was non existence. I have since changed to the Note 4 and immediately I have realised that even in the kitkat (currently running lollipop) that the phone lags when changing between the programs, turning on the camera, or even after a picture has been taken it takes a while to get to respond. Hardwar-wise I believe the Note 4 is very respective and I can only blame this on the software. I have since upgraded to lollipop and I must say the performance is no different than before. Could anyone tell me without rooting and installing a modified rom, is there a way to increase the smoothness of the phone? it is because of the bloatware? how to de-bloat? or is it just how it is?
Thanks
Patrick

the better is a clean installation and after that come back and report any issue's

Thanks vagenrider but this issue was already apparent when I first used the phone right out of the box and noticed the lag.

hi,
I can say this,
that i had my Note4 (N910F rooted, stock Rom.) since October 2014 till now.
Overall i had little or no "lag" of note. (apart from Recent button plus an setting issue.. minor )
Over this period of time, if i found/noticed a bit of "lag" and i found culprit, causing the problem, I would uninstall app,
i also noticed, so far that it has always been a 3rd party (badly coded.. or on lollipop the app was not "playing" nicely.. etc etc)
So overall.... when i was on Android v 4.4.4 or now on Lollipop my device has been working fine.. battery use, been good, very, very smooth
So all i can say, if you have issues it is either you have a faulty device or an app/combination of apps causing lag.or setting issue
I have stated this, in many of my post that i have following devices.. on hand
Note 4, Note 3,Note 8.0 (tab) Note 2 and they all running fine..( 100% satisfaction)
Bottom line
is that i think i am in a good position to state that my Note 4 compares 100%plus, with my Note3(which is a very very, good device, smooth no lag, etc etc)
Above is just my opinion and i hope that you can sort out your device
Good luck

I am having the same issues with my device. I've had it with both lollipop and KK. I've had multiple ROMS (all stock). I've done fresh installs, cleaned cache, disabled apps, and completely run with none of my apps installed. All the same issues, as you've mentioned. I'm thinking of returning my note 4 if they don't fix it by 5.1.1 or August. This device cost way too much for these kinds of issues... :-\

About debloating:
Without root you cannot really debloat the rom. You can only try to holding every app you don't need and drag&drop on touch wiz launcher and drag&drop it to "app details". New window with details will be prompted and you can delete or deactivate the app. This is everything you can do on stock to debloat.
About the main problem:
Also here without root and custom rom I could only suggest to try following:
Go to Settings app.
Scroll down to device information.
Tap few times (I think 5 times shoul it be) on build number to activate developer options.
Go back to main screen of settings, scroll down to developer options and open them.
So from here you can try to change following values:
- Force GPU rendering
- Turn off hardware overlays
- lower values for animations (all three) or just set them to zero if you don't need them. That gives really bounce speed (but mainly just for eyes, it doesn't really chages overall performance of device, just little bit maybe)
The nagtive thing of GPU and harware overlay is little bit higher the battery drain then usual.

Thanks for that!! I've just done the above, will use this setting for a while and see how it goes.

Hi Guys, after applying vbaschen's suggestion I believe the phone has improved in terms of window changing and smoothness in operation. Battery discharge hasn't affected me that much given the battery has always lasted an entire day of heavy use and I plug it in everynight. I would recommend this quick mod. Thanks again vbaschen.

Right on. I was going to recommend reducing the animation values as well as that is usually the case. Hope it helped!

I went for a completely different solution: the Note 4's Snapdragon cpu has the bad habit of heating up very quickly. Two or three minutes of heavy usage (gaming/emulation, or worst: piles of file operations, e.g. media scanner) make it shoot up to 85° C. To prevent serious damage, the cpu is then automatically scaled down to extremely low values, which results in abysmal performance. When I first unboxed my N910F and inserted my old sdcard, the media scanner went haywire because my sdcard was faulty (works alright in my old Note 2, but the Note 4 is picky). The phone quickly got too hot to even touch, ran sluggish as hell (AnTuTu scores between 24000 and 29000), then shut itself down. :crying:
After I had replaced the sdcard, things got better, but only when I didn't put too much load on the phone: 52000 AnTuTu points in the morning (first thing to do with the cold phone), but getting worse steadily until I couldn't score more than 43000 points.
Now, after a lot of fiddling and tweaking (Kitkat, Lollipop, Stock, Custom, CM 12.1), I finally settled for (Lollipop) Emotion Revolution R8 ROM along with the Emotion nightly kernel (r17) and (most important) Synapse kernel tweaker. Instead of overclocking the blasted thing even more, I actually downclocked it one step (2572,8 MHz). The result: a rock stable phone that actually runs way better than with the higher (stock) clock rate. The cpu hardly ever scratches 70° C, and usually stays around 65° C even when I run demanding apps like PPSSPP, Dosbox, or Real Racing 3 (don't like that one, but it beats the s**t out of the cpu - 85° with stock cpu clock!). AnTuTu scores reach about 51500 - almost as much as with stock clock rate - but several times in a row now, with no performance hit. So, even though the peak performance may be one or two percent lower, I can run my phone for hours without any performance drops. Oh, and it's good for battery life, of course. :good:
So, if you're rooted, you may want to give it a shot. :fingers-crossed:

Smart doctor-conserve memory setting missing

Hello
After i updated to oreo i did a factory reset then i installed all my apps .I wanted to use the conserve memory in smart doctor (smart doctor->tap memory->tap three dots->conserve memory).This saved a lot of ram and battery.What can i do?

Oreo does already a preaty good job managing the memory. No need for that setting (even in Nougat there is no real reason).
You can use greenify for that, or even Servicely - https://play.google.com/store/apps/details?id=com.franco.servicely

Idk why but It got significantly slower since the update.The big problem is that is slower in the ui.Before the update hearthstone was lagging a lot but now everything with this phone is lagging.I honestly don't know what to do.Maybe the phone is faulty?

Check you backgroud apps... Maybe is one there that is using more resources.

Interesting... as far as I know on Nougat, disabling some crucial system apps (or even using adb to uninstall them without root) was causing this option to disappear. Yesterday I started disabling some bloatware on my Oreo H870 and I was like "hey, does this option already disappeared?" and yes... it was gone... so I proceed to disable more stuff
But you say that it's gone anyway... As DJPRMF mentioned - Oreo does really good job with memory management. You can also disable background activity for some apps so it's better than on Nougat in my opinion.

Idk but i think that is something wrong with my unit.I mean after the update and factory reset i started to witness freezing and stuttering and not in games because i even deleted them (hearthstone is just so laggy on my phone idk why) my phone froze in the home screen and in youtube. When i checked to see if there is a misbehaving app in the battery usage setting there was nothing everything was normal. I honestly don't know what to do.I can't send it on warranty right now because i need the phone. Any advice?

It's really hard to tell what's the real cause. I also have problems on Oreo but they're not that annoying (practically only related to battery life but NOT standby time which is perfect now). About the stuttering - I also can't say anything, I have absolutely no games installed on my phone.
Try enabling Developer Options (tapping build number 7 times on About Phone) and there is an option to see running services / active services (idk how it's named in English) which is old-style Android task "manager" where you can see RAM usage for currently running and cached-in-memory apps. Maybe you'll find something there?

I looked in that setting but all was normal.I just saw the apps like google and twitter,facebook and mostly things i know i use. The thing is that when i was scrolling to see the list of apps there the scrolling motion was just so laggy. I forgot to mention the battery life that dropped from 5-6 hours sot to barely 4 hours and it's not that i have stopped using it. Idk why this phone is behaving like this.I don't even have it for a full year(just 7 months).I honestly don't know what to do.I have a friend who owns a honor 7 lite and it runs hearthstone perfectly my g6 just lags in it.
