Hi, first of all I love my SGS2, this is my 3rd android phone and I couldn't be happier. This phone is great. BUT... There's one thing that's bugging me. Every rom and kernel I've tried have the same problem. Lag. I'm NOT talking in games or the loading of applications, because this phone FLIES through those tasks. It's small areas where there shouldn't be the smallest amount of lag i.e. scrolling and the homescreen. I hope someone could shed some light on this for me. Everyone talks about how great this phone is and how there's absolutely no lag. Well have you used an iphone. Their like butter. We've got a phone that ****s power and they've got weak hardware in comparison. What gives?
Thanks for reading...
ive noticed if i have the phone plugged into a different charger, ( non oem samsung) there is alot of lag on the phone, its almost impossible to type cause its so annoying! lol its weird cause i thought it was the rom and tried flashing a few roms and it was all the same! found out it was because i was using a htc charger instead of the samsung one. weird cause its the same charging specs and a micro sd cable is all the same!!
Yea I've heard of that. It's indeed weird. I think there is something about it in the manual as well if I remember correctly (yes I read the manual for once!). Any ideas on the home screen/scroll lag?
I'm only on 2.3.3 ROM stock, and it's been great so I don't find the need to flash to other custom ROMS yet
The Touchwiz homescreen for me is buttery smooth. I mean, I've loaded alot of widgets on the thing and it's still smooth
ADW Launcher Ex homescreen scrolling is laggy for me though. No idea why, as the rest of the functions fly (ie app drawer scrolling, app opening, etc)
i also feel there's a tiny lag sometimes... don't know why... btw,i'm using go launcher
I'm also on stock 2.3.3 now and I think I'm going to stay with stocks for a while. I've used different launchers including ADW Launcher Ex and Go launcher Ex but they all have lag at some area. @rantzzz have you used an iphone before? how would you compare the homescreen to our S2. @sept20 can you please look under the battery and see where your phone was made? I.e. mine was made in korea. Thank-you.
Comparing the iPhone homescreen scroll and the Touchwiz 4.0 scroll on SGS2, the iPhone is much much smoother
But the stock Touch wiz 4.0 isn't a slouch also. There is a noticeable fraction of a lag when you swipe, but nothing too big
Thanks for confirming rantzzz. Yeah that fraction of lag when you swype is what I'm talking about. I also experience something similar in my apps drawer. I just can't figure out why Samsung couldn't have optimized something so small and argumentatively most important since it's the portal to everything you do on your phone! Maybe they will fix this in a future update or possibly in ICS.
Well i noticed if i use the 2x4 weather widget i get lag scrolling, shrinking it down and i lost the lag. I dunno if this will help you guys but worth a pop.
I get the lag no matter what, 100 widgets or no widgets. It would be interesting to hear if it helps anybody else though.
OP, Can you give us a full list of all software installed on your device, because I've NEVER seen lag on my phone. I've used TouchWiz, Launcher Pro and have finally settled on Go Launcher, and this phone makes the iPhone 4 looks slow and tedious, so I can only suggest that you have some software that is causing problems.
Edit: Okay, it doesn't make the iPhone 4 look slow. But it is clearly faster and smoother.
A list of software is pointless because I'm experiencing the problem at absolute stock. Whether it is my stock vodafone rom or a stock custom rom. If you wouldn't mind johncmolyneux could you please look under your battery and see where your phone was made? Also what rom and kernel you are using? Thank-you

I have to disagree here, my mate has an iPhone4 and compared to my GS2 it's definitelty not as smooth,my GS2 is much faster too and the display whilst good on both phones is definitely better on mine even my mate (relucantly) admitted that.
Scrollable wallpapers and live wallpapers kill the smoothness. Have a stationary wallpaper that doesn't scroll as you swipe and you'll see how smooth this baby is.
iPhone's launcher seems smoother because it doesn't let you install any wallpaper that'll slow down the homescreen.
I believe it is smooth. My friend (Iphone 4) user actually used my phone and he said that it was smoother and faster than his Ip4. But then again, actually at that time I just purchased it like an hour before. So it was really stock brand new and I have not actually installed anything yet.
I think the word 'lag' is misleading. Lag would actually imply that when you swipe the screen that it takes a moment to react. Do you really have that problem? I do not. The only time I could say I have with lag is the home button reaction speed - which isn't lag, it's because of the voice activation feature.
HOWEVER ...
What I would say is that slowly swiping between screens is far from buttery smooth - I would describe it as slightly juddery. If you swipe fast you barely notice, and if you scroll through the dots it's beautifuly smooth and impressive! BTW I've had 3 different firmwares and casual screen swiping has been equally unsmooth on all..
My question to all is... If you casually/slowly swipe between screens, do you find the animation smooth or a little juddery?

Mine was made in Korea and I'm using stock ROM (XWKE2) that has been rooted.
I've been so happy with stock ROM that I'm not seeing any need to put anything custom on it.
Hope you find the cause of your problem mate, because your phone is definitely not living up to its possibilities! Any chance of a video of your lag?
Im using launcherpro and i dont feel any lag while scrolling in the homescreens :S

Launcher pro reminds me of one que I had- when i was using villain rom 1.4 lite, the launcher pro that came preinstalled didn't have any lag, but when I installed launcher pro on villain rom 1.4 (full version), i felt laggy app browser... why is it so? its also true with adw and go launcher... only thing changed now is that villain rom 1.4 days are gone with release of villain rom 2.0...

Does this sort out the huge font in the notifications? If not, can you change that please?
this is just the a task bar theme for now will do more tonight, just wanted to release the taskbar theme since there were a few threads on it will do all the icons and have it done in a few days, also will do the notifications at some point in my bust week.
so far loving this theme, any chance that you will also change the clock and the settings page to look like stock honeycomb too?
Woohoo! Now I can update. I can't stand the TouchWiz theme, looks like I'm going backwards in technology.

The bar icons, the clock, and the settings page are probably the only things holding me back from sticking with the TW ROM.... I put Calkulin's deodex'd version a few days ago and was back to the vanilla 3.1 in a matter of 10 minutes! It really looks horrible and needs to be reverted!

I think it's humorous that people think there were so many improvements from ADDING stuff to the vanilla 3.1 that shipped with the 10.1.... show me 3 people who have had better Quadrant scores after adding a new UI, because I really didn't see it for the 10 minutes I had it on my Tab before going right back to my backed up stock ROM.
And yes, if I overclock my stock 3.1, why WOULDN'T I want to keep it over this silly UI upgrade???

I don't have a ton of apps on my tab, but I get better performance with stock Android than the TW update.
The only improvement I see is the browser. I can use dolphin to fix that, and the new look is very unappealing to me. I also get better home screen performance on standard honeycomb.

1. Stock quadrant scores are around 1500. Touchwiz quadrant scores are 2300.
2. With touchwiz, the galaxy tab 10.1 is now the only honeycomb tablet with no keyboard lag in the browser. Samsung fixed something in the webkit engine or something. Stock honeycomb on the galaxy tab 10.1 and every other tab in existence has the lag.
3. The samsung Widgets are fantastic.
The killer feature for me was fixing the browser lag. I can now finally type on sites like XDA without wanting to break my tab in half.
But the point at my previous post was that I was shocked that people who remove touchwiz because they dididnt like some icons and colors. This is a computer, not a fashion accessory. Did you buy a tablet to do stuff with it, or for it to look pretty?

This is ridiculous, but since I'm bored, I'll play along.......
Prove it - saying Quadrant scores are X doesn't mean anything to me. I said that in the reply, but you just told me what you thought they were. I ran Quadrant on mine stock and it did 22XX, so I don't know where you're getting this 1500 score..... I got that with a deodex'd and OC'd Captivate, a single core PHONE.....
Two words (that have already been said above) - DOLPHIN BROSWER.... I don't use Dolphin because I really don't see any lag that everyone else is talking about. I have a 4GHz OC'd Quad Core PC, so it isn't like I don't know what a fast electronic device is.....
Widgets..... seriously? so THAT'S what's important on this list? You're talking about comparing this to a fashion accessory (which I agree it's not), and you're talking about widgets??? Really? This is NOT a computer, btw.... my Dell Inspiron Duo tablet IS a computer. A 10.1" touchscreen computer running dual boot Windows 7 and Android 2.2. THIS, however, is something that should work quickly, which I feel it really does already, and look attractive. If you didn't want something that looks attractive, you should have saved your money and bought a Transformer - cheaper looking screen, thicker and heavier device, and you can OC that thing and have all the widgets you like without having to worry about people "complaining" on here about this being a "fashion accessory"
And look at this, I'm not the only one who thinks so:
This update brought some new widgets called Live Panels along for the ride, and honestly, what can I say about them? They're widgets. They have the same look and feel of the other features in TouchWiz UX, but using them is purely optional. I opted to [stay] with the widgets that I was using prior to the update, as I found Live Panels to be much too large for my taste.
From an aesthetic aspect, one of the most drastic changes that came with this update is the Settings menu. It shed its sleek black-and-blue Honeycomb look for a coat of white and some new cartoon-y looking icons. Much like the updated Calendar and Email apps, it's not bad, just different.

They also say all the same things you were saying about the speed improvements and what not, but I'm not interested in making something function faster than it already is while losing the form - you're a car guy, it sounds like, so what if you junked up your Evo X while making it faster? You've already got a fast car, so why not making it look cheezy AND fast at the same time? Yeah, I wouldn't do that with either of my performance vehicles, I don't know many that would......

1) The speed improvement on touchwiz is undeniable... I'm sorry, but Touchwiz is WAY faster and a hell of a lot less buggy. On stock 3.1 (again, right out of the box) I had my browser crash no less than 20 times during around and hour of browsing. It also soft booted 3 times during this period. None of this has happened on Touchwiz. I did not run any quadrant tests, but immediately after installing touchwiz I noticed the speed improvement. No scrolling/transition lag, etc.
2) Dolphin for Tab did not fix the typing lag on 3.1 - Right out of the box I installed it any tried it out. It lags as bad as the stock browser.
3) Why do you care if he like the widgets? If he loves the widgets, that is reason enough to go with Touchwiz
Not it may seem like I am defending Touchwiz. In fact, overall, I really dislike the changes. What I am saying is, touchwiz is, in fact, faster than stock honeycomb. However, the redesign is absolutely terrible. Honeycomb went from modern and sophisticated, to blocky and cartoonish. I would absolutely love the speed and bug improvements without the new UI. As much as I want to go back to stock 3.1, the bugs are forcing me to stay with touchwiz.
EDIT Just ran some benchmarks:
Stock 3.1 Honeycomb: 1448
3.1 Honeycomb Touchwiz: 2267
Like I said, Touchwiz is faster
+1 to better quadrant scores with TW. Stock was in 1500s, TW 2200s and TW plus pershoot's kernel hit 2800!
But seriously,can we get back to the thread title: stock theme for TW. Many including myself would find TW rom + stock theme the ideal for the moment.
I mean, with roms and themes and all, it is for each his own, and this thread is about stock theme for tw.
Will it be MIUI, Cyanogenmod or something else? Share your desires and maybe devs will listen
Definately MIUI.
Using it on my EVO 3D atm, and I loooooove it!
Definitely Cognition Rom
Will be happy to see custom ROMs, but as long as they incorporate the awesome samsung features
I am only looking to put ROMs on this phone that are proven stable - and keep the features of the SGSIII intact. I don't want a phone that needs this workaround to get a feature to work.
I hope BootManager PRO works for this phone because I do like to keep several ROMs at hand at once. I really love the ICS blues and I have seen some amazing things evolve from a stock AOSP 4.0.X ROM over at the GNex forums. So we just need to wait and be amazed with the features that will be introduced to the world of Android via this phone's development section
Kernels on the other hand - this is where I am mostly concerned. We know pretty much NOTHING about the way a quad core kernel should be dealt with... These will be the main subject of my attention as we get into early development stages.
We shall see what some of our amazing developers who have proven they make kernels their bi***es can do with a new kernel. I am also interested in the kernel that Samsung has developed for it and how exactly this works in our favor here at XDA.
The main point is while most ROMs can be considered close... Kernels will be quite different and will be everyone's main focus - making our quad core beasts run with optimal battery life!

I'd like to see a CM9 hybrid\tablet mode rom with per-app dpi capabilities that comes with a free high class escort.
I will use any "rooted" rom that is stable enough .... so far we don´t know is it possible to change bootloader.
Cyanogenmod of course
Probably..... stock rom, bloatware removed (will keep all the good stuff), custom kernel and custom themes
Sent using TCP/IP
CheckRom 100% the most popular and best ever ROM for the SGSII no other ROM comes close, i still use it and have used nothing else for a long time, SGSII ICS ROM's still nowhere near as good as CheckRom although i hear CheckRom ICS will be landing shortly for the SGSII although ill be selling my phone and getting the Galaxy S3
Slim ICS, as don't see much need for all the extra stuff apart from eye tracking to keep the screen on, S-Voice functionality goes in one ear and out the other, NFC not for me, Social tagging can leave me alone, shame the screen is sub standard to the SGS2.
Still loving my SGS 1 but am due an upgrade so may as well get this, hopefully the GPS is not as ****e as the SGS is. ended up buying an iPhone 3GS just to use with TomTom.
Now if you could give me TomTom on the SGS3 then you'd be talking.
Definitely checkrom with a new kitchen. And if we can get a siyah kernel then its over!!!!!!!!

I have tried a lot of latest roms based on XXDLIB JB. For some instance if you open your settings and open a field in your settings, you can sense that when opening that menu, opening takes swiftly a sense of lag, slowness...Not always though, sometimes I open the menus in the settings and the run perfectly smooth. And just trying after a minute, it kinda slows.
I even tried using Custom kernels with that, yet same result. Is it a kind of defect from Samsung's touchwiz rom? Any solution?
Does turning off animations help at all?
Settings - Developer Options, set window animation scale, animator duration scale and transition animation scale to off.
This happens to ma, and is much more noticeable when i open up the dialer, with a second or two pause, with just the bluish bar at the top (where your keypad, logs, favourites and contacts are). I have animations down to .5, but the problem still persists when i have animations off...
The Samsung based DLIB ROMs that I tried all had crap performance compared to earlier ones, so I went back to a DLI4 I think it was (before moving on to AOKP).
Then its with everyone, this is probably my last samsung device. Im moving back to the Nexus line, I bought it for the sake of a better hardware, and here is ? Nothing that special. As well as that we're not capable of running AOSP roms smoothly because of their Exynos close-sourcing thing....What a shame....I have owned S1, S2, Galaxy Note, Galaxy Nexus, and now the S III. Never used Their Touchwiz Rom anyway, always with AOSP; and now with the devs unable to do anything with Samsung's policy, it's better to own a Nexus.

I feel you man. I feel you. On every single XXDLIB rom! No amount of flashing of kernels, mods, etc. fixes this! I also bought the S3 because of the wonderful hardware it offers, only to know after having bought it, that it's lacking proper support by Samsung.
I'm hearing a lot of gossip about an upcoming nexus. I to am feeling switchy-switchy I think? =\
But if it's LG, as the rumors suggest, I don't think I'll feel so 'switchy' anymore.

My bets are on HTC Nexus 5 A 5 inch rocking screen ! And a NEXUS ! That would amazing ! Purely amazing. Especially that I still suffer today from screen sizes ever since I held a Note, my S III 's 4.8 is average for me hehe ! I would SO LOVE a 5 Inch screen Phone!
So I've seen this word thrown around a lot since switching to Android from my old iPhail 3G (yes, I actually lived with that horrible laggy device for ~4 years) and in comparisons between Android and iOS (which I'm not trying to get into here). I've also read lots of people saying Jelly Bean was supposed to be 'snappier' compared to ICS. I wasn't sure if they were referring to lag as in fps or a delay in reaction. My Note II is currently stock 4.1.1, but I'm definitely noticing some delay in games, such as Air Hockey, between moving my finger on the screen and the paddle moving in the game, for example. It's quite noticeable in apps like Maps too. I had the Galaxy S III for a short time before I decided I wanted the bigger (and better specs) Note II, but not long enough to make any comparisons. My question is, is there a way to increase the snappyness without doing anything too dramatic, such as flashing a different ROM, etc. Or will a ROM like beanstown106's Jelly Beans help? Or is this a problem that is inherently part of Android operating system/devices? Thanks in advance.

I can tell you that flashing beans ROM made absolutely no speed difference whatever over my previous debloated/rooted stock ROM (and I didn't really expect it to)
One thing is, it is noticeably laggy when running the inferno galaxy live wallpaper, but pretty much instant response with regular WP.
The "snappieness" in individual apps is really down to the app itself combined with phone specs.
Poorly coded apps may have lag.
High end apps may push the hardware harder and cause lag.
I would bet its mostly the former when it comes to the Note 2.
Samsung also put touchwiz on these phones, which does affect overall performance to some degree. If we get the ability to remove much of it in favor of AOSP versions, then it should perform a little better overall.
The differences between iPhones and Android... is that Apple focuses on user interaction over all other things. So this means they will sacrifice performance in other areas to ensure that user interactions are kept smooth, or at least keep the appearance of smoothness. For example, iOS will stop loading web pages when you start to scroll the screen, so the CPU can focus on smooth scrolling. This means that the page will never finish loading if you keep scrolling around on the screen. Android does not do this or these kind of things. The new "project butter" implemented in JB is designed to help smooth out the interface and user interactions, without sacrificing performance in other areas. Its not perfect though, and it requires good specs and more power than the iOS way of "one thing at a time".
Great response ty very much. I guess next question is will we be able to get those AOSP versions later on or are we SOL in that department?

Depends on which version you have.
I am on Verizon, so my device is locked down, other versions are not.
This device is also unique in the fact it has a Wacom stylus and functionality, so that must be considered.
Often times, you can swap things out without too much issue. AOSP lockscreen instead of touchwiz lockscreen... AOSP launcher instead of touchwiz launcher... without too much trouble. Problem is, underneath the ROM is still touchwiz... or at least that is how it worked on HTC Sense phones. (this is my first touchwiz device) HTC do a lot of work to the underlying framework which meant wholesale replacement of everything wasn't possible, so it depends on how much Samsung changed Android to put touchwiz on it.
Basically they "DE-Touchwiz" the phone and do some background tweaks for added performance, plus they "de-bloat the ROM. (they remove all the unnecessary crap that the carriers and Samsung put in, that served them some benefit, but not benefit the users) The advantage of this method is that you can keep much of the functionality of the stylus.
Another method is to use a ROM based on stock, but tweaked and de-bloated. This usually retains all the functionality of the device as it came out of the box... but the performance is usually only a little better than stock, and less than one where the AOSP stuff has been put in. This method does allow you to keep most of the stylus functionality.
As far as straight up custom ROMs based on AOSP...
They usually offer the best performance for a given device, having no extra crap, and being tweaked for performance... But you will lose most if not all the stylus functionality. Some ROMs may have limited stylus functionality, but they have to put that in themselves, meaning more work on their part.
As far as performance gains... I can only speak of HTC Sense devices with sureness. Where pure AOSP usually had significant improvements to performance/battery life. (mostly due to how extensive Sense is, touchwiz may be better in this regaurd) "De-sensed" ROMs where they removed all of the Sense stuff they could and replaced with AOSP equivalents, had good performance increases. "De-bloated" and tweaked but otherwise stock ROMs had some improvement.
But as was said, the stylus functionality is something that must be considered when looking at ROMs
After using AOSP ROMs quite extensively in both of my two Galaxy 3s, I have no desire whatever to run those type ROMs in my Note 2 (and lose things like pen functionality).
I could never see any performance difference whatever (except maybe in useless benchmarks) between a completely debloated TW ROM with all the features working perfectly and a buggy AOSP ROM in my G3s (and I tried every G3 ROM available at least twice).
Posters where constantly claiming this ROM is PERFECT when discussing any AOSP ROM but two posts later someone else would post "can anybody get NFL Mobile to work??" The next post would say "that has never worked in AOSP but I never use it anyway so who cares........"
Good call. I'd rather keep most functionality

You could go into a store and try some of those games out on a DNA. Hopefully some are free so you don't have to put your google account in the play store and then clear the data. The DNA's gpu is much faster. It sounds like it's the app coding though. I don't have any input lag with on screen buttons playing GTA or N64oid, and emulators are pretty heavy on the processor.
