I felt the same way about my S3 for a long time until I finally flashed tasks AOKP with ktoonz kernel.

For reference, I think the size of the stock rom on the s4 is somewhere around two gigs as opposed to tasks AOKP which was around 500 or 600 MB's.

I haven't even activated my S4 yet because of the frustration I know I would endure when switching between apps, or texting, or pretty much doing anything.

My S3 is RIDICULOUSLY fast now so I have the utmost confidence that once the Verizon phone is out and the ROMs start rolling in, all the lag will be gone once you get away from TouchWiz.

[edit] Task I see you lurking around the S4 boards. I don't know what it all means, but I LIKE it!!! :D

This poster on a Rogers S4 claims he received a factory update that help the performance of his phone...

http://xdaforums.com/showpost.php?p=40960338&postcount=72

Maybe AT&T will push a similar update to help with performance issues.
[AT&T Samsung Galaxy S 4 General] slider2828:
Try Seeder from market. Developed by entropy and just uncheck shut down when screen off and effects to moderate... See if that helps you guys.
[AT&T Samsung Galaxy S 4 General] Mrkrackie:
The only thing I have found to fix this issue is to turn off air view, smart scroll and air gestures. Thus defeating all the new features but removing the lag.
[AT&T Samsung Galaxy S 4 General] MoReNitO303:
How do you do a hard reset?
[AT&T Samsung Galaxy S 4 General] composi:
Forced GPU, animations to 0.5x, disabled all features using motion or eye control, then pulled battery (in that order)... huge difference. Even my keyboard was smoother. Thanks to everyone for the suggestions. No I'm not rooted but I have disabled useless apps. Sucks that I disabled all the gimmicky features that I was actually using but looking at my HTC One the lag on this phone was unbearable.
[AT&T Samsung Galaxy S 4 General] iceman4357:
Settings->accounts->backup and reset->factory data reset.

WARNING--it will erase everything.
[AT&T Samsung Galaxy S 4 General] Bataga:
No lag here. Must be you
[AT&T Samsung Galaxy S 4 General] composi:
Lol really? Its prettt clear that he's not alone, otherwise this thread wouldn't have been replicated 3 or 4 times already. You got a good phone, not all of us were as fortunate.
[AT&T Samsung Galaxy S 4 General] delon97:
Turn off all air gestures and switch the lock screen effects to none, you will be amazed at the speed difference.
[AT&T Samsung Galaxy S 4 General] Bataga:
Never experienced any lag on any device and these threads are annoying to me.
[AT&T Samsung Galaxy S 4 General] AllTheWay:
I returned my GS4 today due to the lag. I don't think a top of the line phone sould have to turn off the feautues and animations on the phone to make it work.

I might think about picking one up again once they fix the issue.

I remember when the first GS phone came out and it also suffered from lag issues as well. Took Samsung a couple of months to fix. In the mean time the HTC One looks enticing.
[AT&T Samsung Galaxy S 4 General] ttnuagmada:
Sadly, this thing feels barely any faster than my Inspire 4G. It lags out hardcore if I try to type more than a couple of sentences in landscape mode,.
[AT&T Samsung Galaxy S 4 General] RMXO:
I have no lag what so ever & have all the features turned on. Only thing Ive done is root, frooze apps I don't need & turned down animations to 0.

[AT&T Samsung Galaxy S 4 General] Skizzy034:
This is like the iPhone 3g being faster than the iPhone 4 when it had just come out. Or the BlackBerry Storm having less lag than a Z10. It just doesn't make sense. Btw in the experience I had, S3 > S4 in the lag department. It actually even felt snappier.

---------- Post added at 12:07 AM ---------- Previous post was at 12:06 AM ----------

Turn the animations back to normal the let us know. The One I'm using right now is at the normal settings and it flies. Let's compare.
[AT&T Samsung Galaxy S 4 General] RMXO:
Set it back to "1" & no lag whatsoever.

[AT&T Samsung Galaxy S 4 General] datrumole:
Even when i got the phone and everything was stock, i didnt notice the lag. But i hate touchwiz so i got away from that as fast as possible. I cleared out every widget from the screens. disabled all the non-sense gimicks (air gestures, eye nonsense....so pointless, i personally don't know why they bother) turned animations to 0, disabled nonsense apps, downloaded boat and maxthon (still can't deiced which i like better), downloaded HoloLauncher HD, holo lock screen, fusion messenger, and called it a day. phone is smooth. Just traded in a SlimBean GS2, and this is buttery compared to it.

And for those complaining about the phosphor lag/poor scrolling on the text. i firmly believe that's either a touchwiz or application issue. If i set my fusion messenger to a black background and white text, i do not see the level of crap that get's lagging behind like the text when i'm in the awful touchwiz settings menu (also white text black background), night and day.

Simply put, the one is a great device, the GF has one. i've played with it from time to time, i hate touchwiz more than i hate sense. the one's display side by side definitely grabs your eye more, bluer whites usually does it, same thing happens when people see a jacked up LCD tv next to a plasma, but in the end the plasma always wins. when all is said and done, and sense is stripped from the one, and the touchwiz is stripped from the 4, and i'm running as close to a bare bones ASOP rom, i'd prefer it to be on a bigger OLED screen, with a sensible button layout (physical home button i could care less about, reversing the back button throws me off), expandable memory, replaceable battery, and over all repairable phone (as i do know at times stuff breaks), i'll stick with the 4, because eventually the hardware will win out, esspecially love the 4 when that aluminum one is all banged up, and so is the back of mine, and i simply snap a new fresh one on

I would also consider returning for a replacement since you guys are within the 14 day return window.

While a lot of the features are gimmicks some are actually very useful.

Smart stay - (the best one out of all them)

Quick glance - (use this all time while it's on my desk or on a table)

Air view - (helps me dig through text messages fast and zoom in on some websites)

Air gesture - (I actually go in the gallery a lot and this makes browsing photos more fun and... natural? in a sense)

Palm motion - (use this all the time to answer phone calls and mute or pause music also use it to capture screenshots :)

Direct call - (I have to admit it's nice and very useful to just directly call someone while simply just moving the phone to your head while in the texting or contacts app)
[AT&T Samsung Galaxy S 4 General] Crwolv:
Have an LGOG,GNEX,HTC1 AND an Sgs4 in front of me and Tweaked right LCD cant hold a candle to the GNEX and SGS4 amoled technology screen. Total TRUE black(pixel is off) and white looks white. Even though lgog and htc1 white is brighter id rather not have an off white lcd gives out. Now its subjective because everyone has different opinions but this is my tiny opinion:) have a great day. If you own a GNEX or LGOG(optimus g) i will be releasing my camera mods for them in a day or 2 and believe me it will knock your sox off especially from what the chip in the lgog 13mp can do :) mods will be released in phones respective area.

[AT&T Samsung Galaxy S 4 General] ttnuagmada:
I did a Kies firmware restore, and while it did kill my root, my phone seems to be pretty much lag free now, even with the default stuff on. You can tell it slows down a little here and there, but nothing like it was. Landscape keyboard seems to work fine now too.
[AT&T Samsung Galaxy S 4 General] finnbass759:
root it, then delete all the unnecessary program.
[AT&T Samsung Galaxy S 4 General] raqball:
People have tried that 17.3 million times!

It does not solve the issue. I now have over 90 app / processes frozen and I am still getting lag on TW.

I installed Nova launcher and it's fast, snappy and lag free but *if* I dare change over to TW is a lag-a-thon

I really wish people would stop posting over and over and over and over and over again to root and remove the crap. We all have done that and it does not solve the issue..
[AT&T Samsung Galaxy S 4 General] yungskeeme:
I have everything enabled and not rooted. No lag at all
[AT&T Samsung Galaxy S 4 General] raqball:
Doubtful but ok....

If so, send it to a museum as it may be the only one on earth!

Every review mentions lag, the devices they showed at the Samsung event all displayed lag, every display model at 4 different AT&T store I went to had lag, and 14.7 million XDA users are reporting lag...

Ya, there is no lag... :rolleyes:

I'm thirsty... Think I will get some Kool-Aid... LOL

Have no lag so far... but this topic made me to go and check running processes...

After 1.5 years on custom SGS I777 seeing trashed memory by bloatware is SHOCKING...

Can't wait for custom ROMs
[AT&T Samsung Galaxy S 4 General] Earthdog:
For me coming from the Note 2 I think its Laggy (I am rooted and frozen tons of stuff) but I agree the issue seems to be in two areas.

1. Bringing up the keyboard is slow (and yes I have frozen all the keyboards) found Swiftkey to be the fastest.

2. The Samsung Email app is ridiculously slow. Unfortunately I can't seem to find a good email app for MS Exchange...

Still trying to decide if I keep it or go back to the Note 2. That .5 inches is a big difference however the added weight sucks.
[AT&T Samsung Galaxy S 4 General] Khalsa4G:
Yes, does anyone know a better email app? Samsung one is horrible. I can't access my business mail fast enough...

I'm using Swype + Dragon and it seems OK. I do notice lag when I swipe to unlock...kind of annoying. :(
[AT&T Samsung Galaxy S 4 General] pt409:
coming from the Captivate, then the HTC One XL, both of which I loved . . .

I agree with Earthdog on which areas are 'laggy'

However, I played with the One and decided that in the near future the S4 users will be happier.

I also have an Asus Transformer Infinity 700, and until CleanRom it was know to be a laggy beast. All the complaints were unfounded with the variations of that rom we saw a smooth running superior screen tablet.

so... I'm not worried here. All the talk of this piece of hardware being a pos or crappy just makes me snicker.:o
[AT&T Samsung Galaxy S 4 General] Khalsa4G:
SO looking forward to AOSP or CleanRom for the S4. Can't come soon enough.
[AT&T Samsung Galaxy S 4 General] Grant H:
For those with high batter drain and GMaps being one of the problems, clear your cache in GMaps and restart. Cleared out my battery drain. Also, my media service was running hard and draining battery. Reformatting the external memory card fixed this problem as well.

Sorry for being a noob but how does one stop media service? And clear out battery drain?

[AT&T Samsung Galaxy S 4 General] murphmar:
Hmm... I did a full restore from settings as some suggested that resolved lag. It did resolve most of it, most notably the stuttering when opening/closing apps (which I could recreate every time by opening Messages and closing, then Chrome and closing (chrome stutter on close) or the other way around). I started adding everything back 1 by 1 and it was all smooth.. until I added facebook and signed in. After that I could recreate the stuttering I had previously... I uninstalled facebook and it's good again now. I have youtube, play music (streaming), messages, gmail, g+, falcon pro, settings, camera, gnow, gallary, clock, play store, chrome all open right now using Nova Launcher Prime and everything is fairly smooth. Much better... odd.
[AT&T Samsung Galaxy S 4 General] sulpher:
Dunno wth you guys are talking about... this thing is even faster than my s3.. :eek:

Thanks for the helpful post... :rolleyes: :rolleyes:
[AT&T Samsung Galaxy S 4 General] WrongRom:
I know I have seen it posted before, but the phone does seem better using a different launcher. If you're rooted, will it help to freeze TW?

Your welcome! Guess you just got a bad s4! Might try warranty~
[AT&T Samsung Galaxy S 4 General] freebee269:
i uninstalled touchwiz. now only using my play store launcher of choice. i set my launcher to be default always and then went and uninstalled touchwiz with titanium. not having any kind of negative effect from it.
[AT&T Samsung Galaxy S 4 General] raqball:
Good grief!

Really??

Added to my 'ignore' list..

Have a nice day :)
[AT&T Samsung Galaxy S 4 General] EVOme:
By looking at the Tmobile and Sprint forums, ATT is the only one that has talks of lag. Not so much as one thread on lag.
[AT&T Samsung Galaxy S 4 General] WrongRom:
Once touchwiz is uninstalled do you lose the ability to use air gesture and such? Not really a big deal if so because I find myself turning them off to reserve battery, but just curious.

Also, have you seen an increase in performance since uninstalling TW?
[AT&T Samsung Galaxy S 4 General] sabre31:
I am in same boat this phone sucks big time compared to note 2. The note 2 is faster and snappier and way better battery life.
[AT&T Samsung Galaxy S 4 General] freebee269:
honestly, i have air gestures off. but i did turn it on to test for you and used the quick glance and it did work.
[AT&T Samsung Galaxy S 4 General] ekerbuddyeker:
I would be interested to know where the phones with lag were manufactured. Some get made in Korea. others in China (same as my Note 2). Perhaps one lags when the other doesn't?

BTW I did a side by side comparison my Between my at&t Note 2 and the s4 at at&t. Generally my N2 was faster at Opening and closing apps and noticeably quicker at taking pictures. I thought that was really odd.
[AT&T Samsung Galaxy S 4 General] MTXR:
I gave it 3 days, I'm returning the S4 and going back to the iPhone 5.
[AT&T Samsung Galaxy S 4 General] Grant H:
You should try swapping to another S4, before taking a huge step back and going with the Iphone 5.

---------- Post added at 06:36 PM ---------- Previous post was at 06:35 PM ----------

My S4 with unbelievable lag was made in China. I believe that there was a hardware defect though.

My S4 that was made in Korea works as advertised with no problems.
[AT&T Samsung Galaxy S 4 General] sabre31:
At this point I agree with you never had any lag with my iphone none ever. I just cant handle the small screen anymore.
[AT&T Samsung Galaxy S 4 General] raqball:
My 1st S4 was made in Korea and it had minor lag and no black crush.

My replacement S4 was made in Korea and has minor lag and has black crush.
[AT&T Samsung Galaxy S 4 General] falconeight:
I don't think the I5 is a step if the new phone doesn't work correctly. There are also other alternatives that work fine; HTC one, note 2, lumia 920, and galaxy s3.

Returned Laggy S4 for less Laggy S4

I don't want to be another "i have no lag!" posts, but just wanted to report my experience. I was also suffering from pretty bad lag but a few workarounds made it "tolerable." I decided to do a factory reset anyway and then things just went bonkers (could have been my fault due to excessive de-bloating lol), so I took it back to the store and convinced them to give me a new one (third one in 5 days, the very first one had a dead pixel!). At the store I went ahead and did a factory reset to make sure things were ok, went home, set up everything one by one as a new phone (no restores from TiBackup), and things actually do seem better. I even kept all the bloatware there *GASP* just to see if that was what was slowing the phone down, but no, it actually seems to run significantly better than my last device. (oh yea all of my devices were made in Korea)

I was skeptical to think that it was hardware related as well, but who knows? It could also be placebo effect, but to me its noticeably smoother even from unlocking the device, opening a few apps, etc, and I don't have GPU acceleration turned on. I also got the previous S4's on launch date, so maybe those batches could have been bad? :confused: All the software should be the same but I dunno, maybe some of them have some bad ram chips or something. Just suggesting since most (if not all) of us are still within the return window, it doesn't hurt to try and swap out the device to see if that helps.

Of course this thing is still not as smooth as I'd like to be (my S3 with Intergalactic ROM runs circles around this thing, but that's also a custom ROM on 4.1.2), but at least I'm finally satisfied with a stock experience until we get a chance to run custom roms on this bad boy.
[AT&T Samsung Galaxy S 4 General] sameer1807:
A factory reset and going thru the process of freezing services thru tibu made a huge difference. definately doesnt lag as much as it did before.
[AT&T Samsung Galaxy S 4 General] mikey2000first:
a little lag

right out of the box I have a bit of lag. I thought maybe it was low on memory from initial setup & browsing everything. But even after a fresh power cycle. I have 700 megs of ram out of 2,000. I am looking forward to removing some bloatware
[AT&T Samsung Galaxy S 4 General] EVOme:
Found this.....

Do you think the Galaxy S4 could react a bit faster when you press the home button? Sure, the smartphone is very fast just the way it is, but guess what - it could do this particular action even faster - the only thing you need to do is to deactivate the S Voice home button shortcut.

By default, S Voice can be launched by double-pressing the home button. This means that when you press the button once, it waits for a few moments to see if a second press is coming. If it isn't, it decides that you just want to go to your home screen and sends you there. This can be the cause for a small delay, which can be reduced by simply disabling the S Voice shortcut.

In order to do so, you need to launch S Voice, then go to settings and uncheck "Open via the home key." Once this is done, you'll be enjoying a faster home button response on devices that have S Voice (including the Galaxy S4, S III and Note II), but you'll also have to launch S Voice using a screen icon. No big deal, if you ask us.

Someone having lag try out holo launcher hd. My theory is that touchwiz launcher has memory leak or soemthing. I use holo launcher hd on 4 phones and no lag for past week
[AT&T Samsung Galaxy S 4 General] jweather:
Just sharing my experience, I wasn't seeing any lag on my phone until I started disabling bloatware, It seemed fine while disabling most of the AT&T specific apps, but once I start disabling Samsung apps (SVoice and S Link) I got serious lag, so much that I couldn't even swipe through pages. Everything became very unresponsive. I re-enabled the two Samsung apps and everything started running smooth again, Don't know if this was pure coincidence or not, just sharing my experience. also when I first got my phone and all the settings and apps installed I went into the recovery partition and cleared the cache.
[AT&T Samsung Galaxy S 4 General] blahblahyoutoo:
saw some lag on the demo unit at the store. then coming to xda and seeing first page of forums filled with posts on lag scares me.
[AT&T Samsung Galaxy S 4 General] ko300zx:
Good find EVOme. This definitely made the home button a bit snappier.

I've had some minor lag issues as reported in a number of the earlier posts, but nothing major and nothing that would make me scream, "return this garbage!" I would be worried I would get one that's worse that what I'm currently experiencing.

I find it pretty ridiculous that if you go into the task manager and "Clear Memory" it will clear/close 30+ applications. Wait 20 minutes and it will clear 30+ again. Some serious ongoing background junk. Everything runs and loads lighnting fast right after clearing it out, but open one thing, 15 processes back up and running.
[AT&T Samsung Galaxy S 4 General] erasat:
I haven't suffering from any lag at all, but I have noticed the little delay when pressing the Home button, but doing this fixed the delay, so yes, this may be one of the issues people maybe experiencing and doing this will help.

Thanks.
[AT&T Samsung Galaxy S 4 General] paleman27:
After comparing it side to side with my SG3, I concluded that there is no lag. If there is a lag, it doesn't lag more than my SG3 on the Intergalactic 3.0 custom ROM. The Camera: Camera takes about 1 sec to open after booting the phone, after that is just fractions of a sec. So it is with every app (messaging..etc..). You know how this OS works; if you kill the app, it will lag while the app is opening again. After that is smooth unless you open to many apps then it will kill the first app that you opened. So forth and so on... Yes, It could have smoother transitions, but the SG3 is no better than this one. But... but...the transitions are not by a mile smoother than my wife's Iphone 5.

If your device lags more than 2 to 3 secs then there is something wrong with it..
[AT&T Samsung Galaxy S 4 General] massih88:
same thing

mine lagged too. So what helps is: turn off remove micro sd if u have one it. That pretty much helped mine. Also window animation and the other few things under dev option to 0. s voice settings and deactivate home button activation. Other then that the touch wiz on this device is compared to the power under the hood to lagy! Im disappointed to be honest...
[AT&T Samsung Galaxy S 4 General] goobieracing:
What I did that got rid of my lag is get rid of tw I used nova launcher and use setcpu and set it to interactive and noop. I'm pretty happy now.
[AT&T Samsung Galaxy S 4 General] paleman27:
How do I go back to TW if I install Nova?
[AT&T Samsung Galaxy S 4 General] thacounty:
Uninstall nova
[AT&T Samsung Galaxy S 4 General] goobieracing:
Go to settings/more/application manager find nova and clear its defaults. Next time you press or go home you will be prompted what launcher do you want to use.
[AT&T Samsung Galaxy S 4 General] paleman27:
Definitely turning off the few things under dev option make a huge difference. Thanx. Now everything is snappy. I didn't pop out the sd ext. because I like to keep my pics there.

As far as the Nova vs. TW didn't see much difference if any.
[AT&T Samsung Galaxy S 4 General] stevehkim:
I suggest no using setcpu. It only changes core0 to the gov. you set and leaves all other cores to default. Try trickster mod or kernel tuner from the market. They change all cores to the gov you wish to use. I noticed it is because under sys/devices/cpu/cpu0 and so on only cpu0 gets a folder made by setcpu. Where as trickster mod creates the folder.
[AT&T Samsung Galaxy S 4 General] cybershawngates:
Is it possible to run 'top' from a terminal command? Or there must be an app that can tell us what is causing lag in terms of which app is causing cpu or mem use

I just installed advanced task killer to see if I could help. Mine shows 267mb free mem. No lag here Page full of apps running. I didnt kill any apps as android should be able to manage it on its own

also installed andrroid terminal free app and ran top.....0% cpu usage.....intermittent 33% but that was from the android terminal app itself...maybe someone with big time lag can also check
