[Q] What causes S-Lag? - Galaxy Note 3 Q&A, Help & Troubleshooting

We all know what I'm talking about.
Have a Galaxy Nope 3 (N9005), stock ROM, go, for example, in Settings -> Connections, and scroll up and down. Chance is, you will see it stutter.
After flashing a multitude of ROMs, AOSP and TW based, I find the stock one most stable, so right now I'm stock, rooted and Wanam-ed.
What exactly causes the legendary S-Lag which causes a device with a quad core 2.3 gHz processor to stutter, and can it be removed without rendering the ROM unstable?

A bad rom or kernel causes it. Tested it out on MultiX 1.5 with kk-Xplorer 1.6 kernel and I dont have it. Then again, i tweaked my kernel and rom to my liking, if you just mass install everything, you will get lag.

Zero lag here, xxuend3, stock kernel, some apps, games disable from startup with android tuner.
Note 3 rooted knox 0, bootloader locked, my last Samsuck crap. I want freedom.

Legendary S-Lag = TouchWiz.
On AOSP no ROMs lagged for me, and I tried practically all ROMs available. The worst case are RR's..
On TW based ROMs, a bad experience means a bad governor from your kernel, for your device. Meaning that your device has a specific governor it likes, and to adjust this use Trickster Mod Kernel Settings available on the Play Store. Also heat dispersion and the kernels ability to scale frequency under high amount of load may cause problems, as the higher heat (theoretically more load) hence stutter and graphical latency.
All clean, stock, custom ROMs play nice because they removed a lot of Samsung's default list of S-Apps, which does free up process load on the RAM and processor. As said before TouchWiz plays a big part in lag, however I'm not saying it's not good. The S5 ports all are great but that's because people actually spend the time recompiling broken/useless code from Samsung's source code. Alexndr is a good example - where he started from 0 to 100 recompiling literally all of Samsung's permissions.
This is why people like debloated ROMs.

(Discussion) EI20, EH09 , EH03kernels, lagfix, heap, memopt and perf tweaks

A lot of controversy and heated disagreements have developed around these subjects so out of respect for devs and members I decided to open this thread.
I have run every iteration of TW rom with stock kernel that has ever been released for this phone with the same results: after a few hours or days of heavy use the phone bogs down to almost a halt. In addition, performance was always less than remarkable.
There have been significant improvements in eh 09 and ei 20, either of these could be my daily driver, but the problem still persists.
Comradesven, imoseyo and djp952 have provided us with custom kernels that are full of the features we love: Bln, voodoo sound and color, voltage and oc options, flashlight, zram, etc.
It is my contention that these kernels + the memory optimizer+other tweaks take this phone from average and dull to snappy and exciting, performing better in every aspect but perhaps paying maybe a little price in battery life and in some cases stability.
I've been accused of giving uneducated and biased advice on the subject. I experiment with this stuff on a daily basis, and my opinions are based on my observations and my phone' s behaviour. Other than the phone testing way higher on any benchmark I ran I don't have any solid proof of what I'm saying

When your phone gets bogged down is all of your ram used? (I've personally never seen mine past 325 no matter how hard I try, because the default android task manager is doing it's job I assume.)
I have had zero problems while running this setup with TSM res:
-Latest imsoyen with recommended settings in setcpu, along with the default zram values
-Dalvik heap 64M (or higher)
-permissions file
-Im not running voodoo lagfix, however thats for reasons other than performance
Do a full data/cache/dalvik wipe before flashing all this, and don't flash anything extra like xix. Also don't change any settings in setcpu, and don't use any task killers. (manually using the samsung task killer shouldn't be necessary)
I'm not saying this will work, this is just my control group because I personally have had success with it. If you give it a go post the results and we can go from there.
Also, do you have any apps from the market that always run in the background? (like tasker or widgetlocker lockscreen)

No, it gets bogged down right after ram usage exceeds 302-304mb. It's like the android low memory killer cannot keep up with the demand or doesn't act fast enough. I do run widget locker though.
Here' s what I'll do. I'll turn off the memory killer and widget locker. My heap is already 64mb. I'll set up the zram at the default value and run it until tomorrow.

Alright well mine does not get bogged down when at those ram values, however I did end up turning widget locker off because of weird lag issues. Would make sense if it's caused by an app.

I also think that there are stability issues running all the other stuff rather than just the kernel. I pulled off adrenaline shot, vm heap, auto memory killer, and any other apps. My phone is now stable and although lag is still present, I prefer a stable phone to random reboots or freezes..

This is so hard to troubleshoot. I thought it was kernel related because I didn't start getting them till TKSGB 10-12(PWGB back then). But now you're reporting getting them on stock as well.
For me they don't appear to happen often, the only way I catch them is by checking the timers on CPU spy.

For those of you that wanna install the latest adrenaline tweaks v12, beware that it makes drastic changes to the low memory killer values. While the phone will run tip top it kills apps left and right. I got rid of it immediately

A trend I have noticed is quite a few folks are having lag and rebots on pwgb and tsm1.0 no matter which kernel or setup. I find it interesting nobody is reporting these issues on ei20 geewiz? I wonder what's different in dj's rom/kernel?
@Sendan. You were correct sir. Widget Locker was creating mayhem when ram got past the 302 mark. I purposely tried to jam up the phone while running a logcat and it turns out widget locker was making calls every millisecond. When running OS monitor it didn't seem that WL was causing any issues.
So basically I've been running without memory optimizer for a day with no issues. The ram usage now gets into the 315-320 range and is able to recover with minimal lag, not enough to warrant the use of akmo./me hanging my head down in shame
So now I'm oc again and trying to figure out what the best zram value is. Phone is running great

Nice thats good. As for other apps that may cause problems....widget locker uses an extremely large amount of ram, it might just be as simple as our phones specs aren't meant to run apps like that. I remember having the lag issues with cyanogenmod so it's definitely not exclusive to TSM Res.

I never had reboots on pwgb w/ tks 1006 kernal... 10/12 is when the reboots started for me just as laurenop posted. I tried akmo and widget locker and it seemed to do more harm than good. I never posted because these damn fascinates all react differently... the only main issue I had on pwgb was browser always shutting down and lag. converting the 1006 tks kernal back to rfs fixed the lag for me, but not for others. The same stuff goes on with every rom including mtd...Im starting to think it's more of a device issue than the rom/kernal combo because so many fascinates will respnd differently to the exact same setup...
i know this comment is a little late, since it seems you all have came to a answer on some slow down issues. But always remember to include apps as a cause for slow down, all apps are not created equal.
It drives me nuts when people say, I have tried every kernel, rom combination possible and it still acts this way. Or when they say I have loaded this on a few phones and mines the only one acting this way. Most of the "its the same" ends at Loading the rom and kernel, once you hand a phone over to its owner, and they install apps thats where it ends. Unless you can say you have the exact same apps as the other person, you can not say its the same.
This is the general rule I do, if i get some major issues, I go to stock, stock kernel and ROM, and Gapps and thats ALL, now I agree running a complete barebones system will suck, but if you have no extra apps installed and your still having slow downs, then you can blame it on the kernel or the rom.

I agree but the easiest way to know if it is a ROM or Kernel issue is remove all the other factors out of it.
Just like when troubleshooting issues in windows, one of the best things in the world is safemode or just removing all the startup items and services.

[Q] The best ROM for gaming

Hi guys,
first of all let me apologize for this stupid question. Personally I hate these questions too, but I have my device in service for 3 weeks, therefore I'm not able to continue with my research...
It's already a long time since I've bought my G2 (D802). Of course, the first thing what I've done > go to custom ROM ... (It's my habit since Xperia Arc S) I think that I was dissappointed of my new LG G2 even then. Games wasn't fluent and lagless as I supposed they should be. It was another good reason to go to the custom ROM. But unfortunatelly and surprisingly it was even worse. So I find another thing why is that so bad. In that time custom ROMS wasnť based on Kitkat sources (kernel), so I hoped that everything will be fine after developers merge source code. But the improvement has never become (in that form I hoped for) In that time I became reconciled that I will never play games on my G2 as smooth as on my iPad.
That's the reason why I'm looking for the best ROM for games. (I'm a heavy gamer)
So my question: Do you know any good rom for Gaming? Could you recommend me something?
I tried Mahdi. PA, Beanstalk, Slim ROM, CloudyStock, Pro, Flex, G3... But none of these ROMs is fine...
(I can't understand how can be Cloudy ROMs so popular (Nothing against Cloudyfa ) because they have too many lags in games !!! I think it's more laggier than stock...

What's the definition of "lagless" for you, and what games are you playing?
First of all, you have to realise and acknowledge that this is a smartphone. No matter what, it's still a phone and it's not made for heavy gaming. Second, you have to realise that despite the fact that many developers (ie Gameloft) has a lot of experience with games, they're too lazy too optimize them even for the most powerful chips out there. The games utilise 100% CPU speed even if they don't need it at all, and then the CPU throttles down because it's becoming too hot. Logic/10.
Thirdly, you have to realise that the ROM is not what makes the game fluid or lag-free. It's the kernel.
Since the G2 (like ALL other phones) is cooled passively (it has no fan whatsoever), it's important that it runs as cool as possible to prevent overheating and throttling.
My advice to you would be the following:
Install your favourite ROM and a kernel you can tweak heavily (gpu/cpu). A good bet would be dorimanx.
Go to kernel settings, and chance max frequency to 1.27 Ghz or around that. Change governor to performance.
Change GPU to 450 Mhz.
Try playing a game =)
I used to play Asphalt 8 back when I first got the phone and I got about 30 FPS? Anyway it was smooth as butter, and I see no real reason why you want to put a custom rom on your phone. The good 'ol days where nothing was better than custom roms are pretty much over. Stock is just fine, root it, use a custom kernel if neccessary and use xposed. Will solve it.

Of course that kernel is the most important thing in performance (because of sequencer laws, etc...), but nowadays we have no (except render) custom kernels for AOSP/ CM ROMs, so my question was focused on a ROM → I connected it to the whole... (And furthermore each ROM has own kernel. + ROM can cause lags as well)

Unfortunately these times are gone, at least I think it. There were lots of updates, which increase the performance consumption (Simply they add tons of new features and stuff, but they ,,forget" to optimize that... ) I played this game, Dead trigger 2, Dungeon Hunter 4 and even simple games like traffic racer with incredibly high count of lags (And it wasn't lags in miliseconds → not always). I thought it was because of my current ROM (Mahdi) so I tried PA and then stock based ROMs (CloudyFlex, Stock) but nearly no changes) Therefore I think it will be the same on stock ROMs too, if it's on Cloudy ROM with heavily optimized kernel, system...

Thanks for this tip, I tried something similar but with UC to 1,9 GHz and I didn't set governor to performance (My device was incredibly hot in a while with performance governor), I didn't notice any bigger changes - I expected that lower frequency will cause even more lags and I was obviously wrong. For sure I will try your advice.... :laugh:

I don't like the LG's design of system, and I don't like xposed → it causes higher battery consumption and it ,,eats" RAM and performance (At least on my previous device )
i have 10 xposed modules installed and i didn't notice any additional battery decrease...
as for ram, as stated many times - free ram = wasted ram...
as for the thread - "what's the best this&that" threads aren't allowed on xda
i played rr3 and csr racing on this device and didn't notice anything wrong with the framerate (stock kk v20f, rooted with dorimanx kernel on default)
Oddly enough, I haven't noticed a major change in gaming performance coming from the S4 Pro. Asphalt 8 specifically is buggy, sluggish, etc on my LG OG & G2, but I don't care for android gaming since the apps aren't optimized (too many HW configs, whereas iOS is just SGX & Ax chips).
Transmitted via Geass
First of all, I like to say that we lacked similar threads, so OP started an useful topic. I would have stayed with simple dual-core smartphone, but I bought G2 in November for a reason, to try new games and so on, I woudn't have bought it if I needed a phone only for texting and browsing, like many argue like this. What I observed is that, 2,3 Ghz for a phone with passive cooling is a nonsense because after few minutes of gaming it will keep running like 1,5 Ghz and lower, hell what's the use of those 4 cores if a device would burn out. I never owned an apple product, but on my colleague's 5S, they run very smooth and fast with same graphics on a dual-core, so it all goes to optimazing and not using these ridiculous frequencies. I was expecting a lot from a phone like that, sorry for a long post.

S4 overclock

I just put OmegaROM v42, 5.0.1 on my i9505 and I'm finding some games a bit laggy.
Running imperium 2.2 kernel.
There are lot of overclocking apps out there, just wondering which is the best/most stable of them.
I downloaded SetCPu but cannot seem to push the S4 past 1890mhz.
Can the GPU be OCed as well?
Firstly, the kernel needs to support overclocking.
Secondly, you can also do that from within the kernel tweak app (e.g Stweaks).
If it won't go past 1890 then it doesn't support overclocking.
The only 5.0.1 kernel that supports overclocking for touchwiz is Hulk-kernel as far as I know. Currently up to 2.1 GHz overclock.
It doesn't support GPU overclock yet. But from what I saw the dev might be planning to add that too in the next version probably.
Make sure you download the OC version.
Also, I don't know what games you are playing that seem laggy, but it may be caused by DVFS.

I was playing Relic Run and it seems to get laggier the more you play.
How to fix the DVFS issue?
DVFS or Dynamic Voltage Frequency Scaling is present only on touchwiz roms. I don't know if DVFS is rom related or kernel related, or if it is disabled by default on custom touchwiz roms. But there is an Xposed module to disable it. I don't know if there is any other way.

Why the huge performance discrepancies between Rom's ?

Bit of a general question here, but I am getting some really wacky benchmark scores. They're all over the place and id like to know if any of you guys have found a rom and kernel that just works.
I've tried quite a few custom rom's now both Lollipop and Marshmallow, and they've all offered underwhelming performance (Not much faster than my old 801 soc device).
Albeit for the exception of resurrection remix, of which gave me phenomenal in game performance and AnTuTu scores within the 7700 range. A HUGE improvement over stock and other custom Rom's. Unfortunately Resurrection Remix 6.0 is by far the buggiest rom I've loaded, soft reboots everywhere, no working camera and artifacts.
Any recommendations for a good rom ? or should I be focusing on kernels with say stock Oxygen OS ?
I would say stay on OOS so that you can use all Sensors (FP and LF) and give Boeffla Kernel a try. Gives me amazing performance and pretty good benchmarks if i configure the Kernel to give me max performance (i dont do this often because a Benchmark score says nothing). With a balanced setting on the Kernel you get good Battery life and a good performance for daily use.
Use stock with Boeffla, guaranteed stability and from what others have posted with their tweaks seems best option. Everything else looks too experimental or unstable.
just use kernel auditor and use these settings; govenor-interactive, scheduler-row, readahead-1024, in virtual memory dirty ratio-30, dirty background radio-10, swappiness-10, Z-ram-250, under entrphy read-128, write-256. you will hit over 90,000 on antutu with stock rom. I've used these setting with stock with stock kernel, skydragon and oxyslim. i prefer stock now, i just uninstalled the apps i don't use plus oemkitlog, oneplus telephony, com.codeauroroa.img
But why should you even bother with Z-Ram when you have 4GB RAM in this phone?
Doesnt make any sense for me ...

It is totally pointless in a system with 4GB (even 3) RAM, wouldn't add performance since CPU now has to compress/decompress data on the fly - but what I'm wondering is: does Android have ZRAM by default or is this added? If it's added, lose it. If you were running an emulator this would be a hit.

Heat issues on custom roms

So, I noticed that the phone heats up significantly more while using a custom ROM. All I've tried do it (purenexus, exodus, cm). Right now I'm running trupurexmm and it's fine, presumably because it's modified stock. Does anyone know why this happens, or can recommend a good 6.0.1 ROM that doesn't?
Thanks!
Sorry I can't make a recommendation, but I assume the reason the modified stock and stock ROMs run cooler is CM and various others most likely lack the stock thermal-engine config which controls CPU throttling and hot-plugging.

Is there a fix for this that you know of?
I'm running CM right now and have used two other custom ROMs. All of them run hot at first, there's a lot going on after flashing a ROM and it's CPU extensive so they will get hot. After the dalvik gets rebuilt and everything settles down the temps return to normal. All the kernels have thermal throttling of some sort otherwise the phones would self destruct.
My limited experience with CM on a couple of phones is that the CPU governor doesn't work. There have been numerous fixes recently that help but it still doesn't work as well as stock overall. Stock was a bit jerky, so there are a few cases where the CM governor might feel better.

Not that I know of.. maybe a custom kernel? Not sure if CM's kernel is configurable as far as changing CPU hot-plugging and throttling thresholds.
