[Galaxy S 4 Q&A, Help & Troubleshooting] lemonz23:
I've been hearing on some reviews that there are some moments that the Touchwiz UI will have an occasional stutter or lag. Do you guys think that downloading a different launcher, like Apix, will help solve that? Or will I have to go to the dark side of the phone and root it?

Also to some of you S3 owners out there, did installing CM10 or any other custom roms help remove any signs of lag or stuttering from the phone?

i noticed the same on mine... Its a GT-I9505...

My Nexus 4 is smoother....
[Galaxy S 4 Q&A, Help & Troubleshooting] MultiLockOn:
I'm afraid to get the s4 because of that. Everyone swore to God that the note 2 was the most fluid device they ever touched with no frame rate drops. I recommend it to two friends, come back two weeks later to find both of their phones a lag fest. There might've been some user error there, they both had 2 or 3 weird apps installed, and I attempted to diagnose the problem but alas the lag remained, with and without apex. It was kinda embarrassing

for me when they both went in to trade their note 2's for an iPhone 5, because of the horrendous lag they suffered.

I say all that because I potentially see that happening here again, especially with touchwiz now BEYOND bloated with features. Not to mention the phone probably isn't optimized for snapdragon the way it is for exynos...

Don't get me wrong I love sammy phones, I think they're incredible as I'm still rocking the s2. I just have a hard time recommending them to people because of the horrible experiences a regular user faces without rooting and throwing an aosp rom on. And it's not like I can freely suggest nexus phones as the nexus 4 is exclusive to gsm (most my friends are on Verizon/Sprint) and most don't like the idea of paying off contract.

Anywho I rambled a bit. Long story short, I'm the biggest Samsung advocate in the world but even I'm skeptical of getting the s4 because of performance drops such as the ones mentioned

I'm guessing it's the use of 4.2. It was a big step backwards from 4.1.
[Galaxy S 4 Q&A, Help & Troubleshooting] lemonz23:
Did you ever try to install a custom rom for any of those devices? The only smart phone I've owned was a Samsung Infuse (The little brother of the S2) and the lag on that phone was terrible, despite the amount of roms I've put on it.
[Galaxy S 4 Q&A, Help & Troubleshooting] CLARiiON:
I have seen lag in the widget drawer, first time when you try to swipe to a different page in the widget drawer. Seems like 4.2 update have broken a few things in terms of smoothness.
[Galaxy S 4 Q&A, Help & Troubleshooting] sixstring:
So did I. Didn't notice a lag in other screens, though...
[Galaxy S 4 Q&A, Help & Troubleshooting] JihadSquad:
I still have the Droid Charge, the Infuse's ugly brother on Verizon. They both use galaxy S hardware in the age of the S II, and Samsung didn't really give a crap about them software wise. I remember when the Charge got the gingerbread update there was a line that read something like this in the source:

/*This is a temporary piece of crappy code that I was forced to write as I did not figure

out how to properly use the driver in the system. Please resist the temptation of ever using

this code in a good Samsung phone. I will remove this code as soon as I figure out the correct

way of using the driver*/

The old hardware and the bad development are likely the problems. We did just get an OTA update a couple of weeks ago that fixed a lot of lag, though. Maybe it was that guy's driver, who knows.
[Galaxy S 4 Q&A, Help & Troubleshooting] wednesday13:
It's an existing feature in Samsung phones called S-lag.

So how's the dialer? Does it still open for 3 secs?
[Galaxy S 4 Q&A, Help & Troubleshooting] mr_sock:
I read somewhere that the lag is not the devices themselves but more on Android's native coding (how it was built ground up). Android works like a computer and differences are the way it utilizes the CPU/GPU. For example, when you are browsing and click on something on iOS, it stops everything and performs new instructions right away. In Android, it still process last set of instructions.

So Android reduces the lag by brute force by (dual, quad core, more memory, GPU etc) whereas iOS, because of different coding they don't need to. Many apps on Android are really customized versions of Java. And didn't Steve Jobs eliminate Java because it is too slow/power consuming for Mobile?

Even Nexus devices lag. When you turn on the phone and start scrolling and browsing right away really fast there is some lag.

Note II with Nova on here, and zero lags (except if you unlock from deep sleep and immediately without waiting, like within 1 second or something, pull down the notification bar, there's a lag, but that's me being nitpicky here). I guess it's a snapdragon thing rather, I'm on N7100 international Note II. Can vouch for that anyways.
[Galaxy S 4 Q&A, Help & Troubleshooting] patelkedar91:

On engadgets review, they say that the air view and air gestures seen to make the phone a lot more sluggish. So hopefully disabling one of those features will help speed it up.

Note 2 user chiming in. Not even mad about lag. There is no such thing as lag free. Show me proof if there is.

Also got an GS4 arriving tomorrow. Removing bloatware as soon as I gain root.
[Galaxy S 4 Q&A, Help & Troubleshooting] lemonz23:
When I was trying out the note 2 at the att store I noticed that some of the transitions would stutter from time to time (getting inand out of the app drawer, notification pulll down stutter) When I was trying out the HTC One, the only lag slight lag I got was on the widget select screen. Everything was literally smooth and fluid, it was awesome! The only reason why I was sold to the S4 instead of the One was because of the power button and volume buttons being so flush in the casing. I would have to slide my finger across the top just to pinpoint the power button which was very annoying and so I was thinking of avoiding the One. And I honestly like the design of the S4 more. But even the slightest lag on the S4 will deter me away from it, if it is constantly happening that is.

I hated the lag on my htc evo 4g, even sending a simple text message seemed like a chore for that little device. Over the months, though I have come to realize even the iphone 4s I have lags. I tried out the nexus 4 which was indeed buttery smooth. I suspect it has to do with the fresh reset and not installing a bunch of apps. However, if the native apps or basic functionality lags (like answering the phone / unlocking / sending text) that would be a let down.

Hoping for the best! Heck I already pre-ordered it so what's a few more days of wait.
[Galaxy S 4 Q&A, Help & Troubleshooting] MaKTaiL:
Guys, the reason the Dialer takes so much time to load is because Samsung is still using the Gingerbread code for it.

They are doing this is to keep the Facebook native sync of contacts. It's the only sync that brings phones to the Contact list.

It takes a little to load but I'm totally fine with it if I can keep the sync.
[Galaxy S 4 Q&A, Help & Troubleshooting] -]Megacharge[-:
That might explain why HTC said they opted to release with 4.1 instead. I remember hearing they made the decision regarding performances issues, but they didn't specify lag, we can see it in some videos though, the HTC One is silky smooth while we have some stuttering in some GS4's.
[Galaxy S 4 Q&A, Help & Troubleshooting] poweroutlet:
The hardware in the S4 is obviously very fast. Samsung just needs to get TouchWhiz on a weight loss program, it's starting to get a bit out of control. I don't own a Nexus 4 but I recently got to use one and honestly it felt more fluid than the Note 2 and from what I've seen on videos the S4 as well. My S2 is running the latest official samsung rom android 4.2.2 and although its fairly smooth it just doesn't compare with AOSP 4.2.2.

It's a bit ironic now that Touchwhiz is the heavy weight overlay and HTC Sense 5 is relatively light since sense was always the pig in the past.

However, a good point here is the OP said that the battery with all stuff (smcrap features) turned on was more than 4 hours and 12-15% left, so if turning off all we can get more.

Custom roms are not lag free and 100% of the time there's something buggy or not working.

Many here make it sound like o final solution..
[Galaxy S 4 Q&A, Help & Troubleshooting] tuxonhtc:
Which UI is exactly 100% lag free? Even the Nexus 4 has the occasional lag, which is stock android. What are you on about?

And that's a terrible generalization. Some custom ROMs are terribly buggy, but some are really good and stable once it's past the initial stages.

They're not even out FFS, how do you know that there's something buggy?

Not defending Samsung obviously, should've done a far better job with the UI fluidity.
[Galaxy S 4 Q&A, Help & Troubleshooting] SlimJ87D:
Nova launcher, problem solved.
[Galaxy S 4 Q&A, Help & Troubleshooting] lemonz23:
Putting on a new launcher doesn't fix much lag. You still have the buggy touchwiz ui in the background. I just hope that freezing the bloat ware and disabling the air gestures n crap will give it a dramatic speed boost so the fluidity could be compared to the HTC one. Can anyone with an s4 see if it disabling the features will help?
[Galaxy S 4 Q&A, Help & Troubleshooting] CLARiiON:
Fluidity like this??
[Galaxy S 4 Q&A, Help & Troubleshooting] lemonz23:
imo, those numbers were completely opposite based on my user experience. When I was demoing the HTC One at the att store, i also had the chance to try out the note 2 and galaxy s3. The note 2 and the s3 were far less superior compared to the One in terms of ui fluidity.

Ok one sec let me just drive to the nearest AT&T store so I can please you with some numbers. I'm kidding. I was just saying that my overall user experience with the Samsung devices wasn't on par with the HTC one and that the graph you posted was completely useless for me because it differed from my experience.

Im not advertising the one, I wouldn't even be on this section of the forum if I went with the One. I'm just trying to find a device that I will still be happy with in 2+ years, and i was hoping it was going to be the s4 and I've even bought screen protectors for it lol. It just becomes annoying when people "choose sides" with phones because then they become completely biased and claim that everything is perfect with it when in reality it contradicts everything they've claimed because they're trying to defend their devices. But I guess it all just comes down to what opinion you have towards each device and its up to the person themselves to go and experience the phone on their own. I just want a phone that will aesthetically please me on the long run.

Have you tried to disable any other of the new air features to decrease any more potential lag?
[Galaxy S 4 Q&A, Help & Troubleshooting] JChespirito24:
Air scroll is the only other thing that makes it lagg a little. Nothing else has really helped. After disabling those 2 it works pretty well

I was pondering getting the htc one as I really like the stereo speakers but thought the s4 camera would be way better and that hopefully the lags in touchwiz would be gone.

I've had every galaxy s phone released and pre ordered the s4 twice (each order being delayed/price increased so cancelled with the retailers). I planned on waiting until it's in the shops everywhere and maybe a better price.

When I called into CPW to check on my 2nd pre order I played with the s4 on display and it was laggy scrolling through the home screens. Never mind I though, it's new, it will get a firmware update that should fix that. Then I remembered....

That's EXACTLY what I presumed would happen to my s3, yet a year on and it's still redrawing home screens and lagging when scrolling. Fixing this (kind of) with mods is an option I know.

The camera reviews point to the htc one being the best for flash photography and indoor shots, with the s4 best for outdoor. I have a good camera I take on hols or events anyway and looking through my gallery most are indoor shots, rarely with good light.

Then there's the storage, I convinced myself I needed an SD slot. My s3s class 10 32gb has never been more than half full. With the s4 having only 9gb free for installing apps and rumours that there won't be a 32gb s4; that 32gb space for anything I want on the one seems more appealing again.

It could be the man flu I have right now and maybe after a good night's sleep I may change my mind, but tomorrow I'm going to buy the htc one that didn't lag, looked nice, costs less and sounded awesome.

Anyone else feel this way?

There are many videos with laggy sgs4s... looks like they continue the sgs3 jb update performance.
[Galaxy S 4 Q&A, Help & Troubleshooting] Gadget_Grover:
I know what you mean. I bought the HTC one a few weeks ago. Love it. Got an s4 today because of the extras like the bigger screen and battery life and the gimmicky but fun ones like air view and gestures. Was very excited as the HTC set the bar very high but having owned the s3 and note 2 before the HTC I was sure Samsung will impress but the lag is unbearable. And stop recommending turning this feature off and that feature off. I didn't choose the s4 over HTC to be turning off features, some of which are it's unique selling points over the HTC, to be turning them off so that my quadcore phone can redraw it's UI properly!

I think it's the Snapdragon that's not optimised for TW. Would be interesting to see if any Octa variant owners are experiencing any lag.

I'm gonna wait a few days and see if it improves with an update but it's decision and selling time for one of these.
[Galaxy S 4 Q&A, Help & Troubleshooting] patelkedar91:
Talk about a HTC One pro thread.

Anyway, from the videos I've seen the GS4 isn't laggy. I heard there's some stutter here or there which is weird considering the Note II is the smoothest device ever.

It'll probably get fixed with an OTA update soon if that's the case.
[Galaxy S 4 Q&A, Help & Troubleshooting] fade2green514:
actually i saw a drop test where in a drop from pocket height the speaker popped right off the htc one. and they couldnt even super glue it back on. it was a goner.

also, in that review posted, it seemed to be laggy in the default browser before the webpage was even loaded... and in dolphin. chrome seemed to be the best. i'll have to judge for myself when i get my s4.
[Galaxy S 4 Q&A, Help & Troubleshooting] skibadee:
I'm not pro htc, like I said I've had all the galaxy s phones & never owned an htc before.

I've seen the s4 personally so I don't need a video to show me lag.

Maybe I'll wait and see if it is resolved. I'm thinking of the dead pixel chances now on htc one which you don't get on amoled screens. Had a lot of grief with nexus 10s displays a few months back.

One things for sure they (Samsung) aren't getting my money first this time. Played that game already.

If it's software end issues, I'm sure devs will help with that here, if not the with software update. Both phones have flaws, but for both, pros outweigh the cons. Choose your pick.

I've heard some lag complaints with Note II before as well but mine was/is smooth as butter even with all the motion etc. enabled, it seems this is mostly with career devices, not unlocked ones? Did anyone get rid of the bloat and see if there's still lag?

Its the software. My GS2 with CM 10.1 is smoother than the GS3/GS4. IMO if you want smoothness with no lag or missing frames, get a Nexus 4.
[Galaxy S 4 Q&A, Help & Troubleshooting] nookcoloruser:
Are you trying to hide reverse insecurity. ? ;)

The reason people are comparing is that these two phones are out at same time and both offer similar hardware specs but approach android skinning differently. Therefore it does give us an accurate test bed to see if those differences result in overal differences to user fluidity / experience.

This is not about 'mine is better than yours' its about being able to compare similar specced hardware and seeing if Operating system and manufacturers changes have impacted on the performance of either device.

I was wondering if memory management could explain some of the lag or redraw or stutters.

I noticed on the one (sorry opz) that it generally hovered around 500-600mb of 1.5gb available used with 9 random apps open. 512 is reserved for system hence 1.5gb showing as available.

However on my white S4 similar amount of apps open (no games so no resource hogs) and yet system is telling me that its between 1.4 & 1.6gb of the 1.8 available. I mean is Touchwiz 'SO' urnoptimised that it eats that much more memory ? Why such a discrepancy in overall memory usage?

As a reference I have smart features turned off, multitasking window off and air gestures and air view all turned off.

Yet I have noticed lag on my S4 compared to the One I returned due to defective lens. Launching camera you can sometimes press the camera icon and there is a 1 or 2 second delay before camera opens or when you open gallery it seems to take fractions longer to draw / refresh the photos, whereas all that was instantaneous on the One.

It does lead me to believe that Touchwiz is far less optimised for performance. Either that or 4.2.2 is buggier than 4.1.2
[Galaxy S 4 Q&A, Help & Troubleshooting] kirdroid:
It is a great phone but ergonomically little bad since holding it for long is not great. I mean both are great phones so anyone who buys either of them will enjoy. Personally i don't keep phones long, so when the next set of flagships come in 6 months time i will be selling these and moving on to new things.
[Galaxy S 4 Q&A, Help & Troubleshooting] opz187:
But I mean you have to like one a little bit more than the other, right? pretty much all the specs are the same between the 2, and honestly I don't use external SD card, so the 32gb htc one would be more than enough for me, so it came down to.. Get this, gorilla glass 3. That's what made me choose the s4, I heard good things about the screen. But I tend to hold onto phones a little bit longer, so I'm try to make a Democratic, healthy, well informed decision on which one I will call mine. And I appreciate peoples opinions based on their experiences. And I have 24 hours if I want to cancel the s4. But I guess I could always try it out before the 14 day return period expires. But I will be rooting as soon as I get either, so....
