[Galaxy S 4 Q&A, Help & Troubleshooting] CJLewis87:
I agree, the camera shutter lag needs fixing, and so do some of the moving object(s) issues. However, I have managed to snap some brilliant shots using the new camera and that has been one of my favourite upgrades since moving from the S3 (some great shots of my Rottweiler on drama etc., like the duel camera/video too). As for the general TouchWiz scrolling, I also agree. Even the chat bubbles in messages/contacts page would stutter on the S3, where now they seem buttery smooth. The only stutter I seem to get now is in call/message logs. As you say, the advanced options have been split into tabs now, but even scrolling up and down developer options etc. is fine.

So to have all those improvements, and then have this random jank every now and then, is just puzzling. It's got to be down to optimising the software, which we'll hopefully get in the next update. As for JB 4.3 (or 5.0 etc), Sammy are doing to need to do a better job optimising TW. Don't get me wrong, unlike many, I'm actually a fan of TW and like its UI, but it seems to be an unnecessarily heavy skin, which is hampering outright performance.

I've recently had a chance to get my hands on the Galaxy S4 in my local T-mo store. I was really curious how well it would perform in UI compared to my Nexus 4. Holy Mother of God, it was TERRIBLE (scrolling in the app drawer, scrolling in settings). As for a >600% phone, this should never happen. When I've taken my Nexus out of my pocket I just couldn't believe how the new S4 was laggy. I don't know if it's widespread or not, but judging by many YouTube videos showing this lag, it might be. I'm glad that I hadn't waited more and went for Nexus.

Some people may be more sensitive to even minor lag/stutter or tolerate other better than other. I wondered when some people complained about delay when opening e.g. contacts. Obviously delays do not bother me as I did not ever notice this delay. But stutters drive me crazy and I notice them immedeatly. :)

Reminds me of when friend was playing a game with computer and I asked how come the stutter did not bother him. He did not understand what I was talking about and game was fine in his opinion. Lucky him, he did not have to buy latest hardware all the time. :p

[Galaxy S 4 Q&A, Help & Troubleshooting] naveediftikhar:
OK to all those guys who say that the lag is due to the touch wiz interface... Seriously.. It's like saying that iphone4 was small cause of the screen size and not due to Apple's final decision... It's the final product that matter.. If Samsung decides to implement certain features in their phone it should be implemented perfectly.. I don't want to buy a 600 dollar phone only for it to get better with time.. I want the baby to shoot stars from the word go... S3/s2 all for better software's with time isn't an excuse.. It's just poor management and customer support.. Samsung has always been poor at fixing bugs and all...i have never seen a single HTC device after sensation to have any software issues out of the box.. But my s3... Damn the baby lagged like hell in it's settings menu.. transitions were buggy which i accept got better with time but i had to live through hell for 3 months cause where i live it cost me 50000... So yeah "it's just the home button lag" doesn't cut it... Its a freaking quad core phone..i myself was a Samsung fan boy for a while but all this no source code don't care about the developers attitude of Samsung put me off... and what's the point of buying s4 if you eventually gonna Debloat it why not buy a s3 as all new features are practically just bloatware..!

I've had an s3, a note 2, and a nexus 4, and as far as smoothness the note 2 and the sgs3 dont even COMPARE to the nexus. Both the note 2 and the s3 drop frames and look choppy when opening apps, scrolling is laggy as hell on the sgs3, both the note 2 and sgs3 drop frames often on the homescreen and just the general interface. Nexus 4 has such minimal stutter, it's fairly rare. Touchwiz unfortunately is still fairly unoptimized for their flagships (why?) and doesn't take full advantage of the massive power in the phone, they just hope that the sheer power will iron out software optimization problems.

AW: Galaxy S4 laggy?

S3 lags? That was your fault and no one else's!
[Galaxy S 4 Q&A, Help & Troubleshooting] optimusinc:
s4 may use octa core but truly speaking it only runs on quad core processor..... :P

It uses ARM's big.LITTLE architecture which aims on power conservation and performance.So they typically have two quad core processor CA7 and CA15

these switch between tasks as of low cpu using tasks like texting calls and standby the device runs on armv7 so that the battery saves more.But when you use more demanding tasks like games , watching videos , apps etc the device switches to arm v15.This might be the reason for the lag.But im sure it will be fixed...

Nothing is completely smooth. Even my ipad and friend's iPhone 5 suffers very minor lag and so it would be smooth probably 99% of the time, but not 100%.

You can't expect software to be bug free either and to be brutally honest with you, no stable or so-called bug free software are actually 100% bug free.

Nothing is perfect and people can't expect first release of android, ios, windows phone 8 to be 100% bug free from apps, battery drain, reception, GPS etc..... (Referring to software related of course).

Does the s4 still have the lag/delay opening contacts and messenger?

Can't believe the s3 STILL has this issue.
[Galaxy S 4 Q&A, Help & Troubleshooting] -]Megacharge[-:
I think it's touchwiz. Not sure what exactly causes this, but I've had this issue with my original SGS and also on my SGS2, I've heard users complain about it on the S3 as well, and now I'm seeing the exact same thing on the S4 in videos. So far it's been 3 galaxy iterations and a few years, and this issue doesn't seem to be fixed. On the other hand the HTC One's UI is buttery smooth. How are they able to do this, yet Samsung can't? Hopefully the S4 has this fixed by release date, but considering this has been an issue throughout their whole Galaxy line since the first Galaxy, it doesn't seem likely.
[Galaxy S 4 Q&A, Help & Troubleshooting] Baldilocks:
It's because it's waiting for more input for voice command. How many times do we have to post it? If you don't want the delay, then turn it off in the settings.

If you want to speed the phone up even more, use Nova Launcher or Apex.
[Galaxy S 4 Q&A, Help & Troubleshooting] skibadee:
Thanks for your input however if the lag going back to the homescreen, is the ridiculous redraw that he is talking about, turning off voice input does not help.

My voice input was disabled long ago, yet I still get screen redraws on exiting apps.

I'm aware modifications can be made, ie custom rom, or using a different launcher. However, if like me, you use the s-planner widget (only available on touchwiz) or don't wish to flash custom roms, it's not acceptable. Especially as my s2 didn't do it!

Android is laggy and Samsung Overheats

I've been using iphone for the last 4 years and a month ago i decided to upgrade form 4S to the Galaxy Note 2. I was impressed from many things of the Note 2, screen, camera, interface, hardware specs, line of design ect... But the only things thats does not fit its the Touchwiz response. It feels laggy. Many android users deny such thing, but the truth is that comparing to the ios the difference its obvious, i mean u can't play games, or use music instruments apps. Ive been testing for the laggy part even Htc One X, Nexus, Note Tab, and they too have the same problem. I've read many posts and same say its the Android's falt. I hope they fix this issue in the 5.0. On other thing is that while playing heavy games like NFS Most Wanted, Gta Vice City or Street fighter 4 they get pretty damn hot.

Try an iDevice and explan now the tabs are "still smooth and not laaaaaaaggyyyyyyy".

I mean phones are acceptable in tearms of smoothness, but tabs even the Note 10.1 feels laggy and so is the Nexus 7.

I don't expect iOS smoothness in tabs, but for someone like me who is used to the i9000's gingerbread lagness got pissed with the Nexus 7 after a few hours of getting it. lol the stupid corner cracked at the end after well placing it (not exactly roughly) onto table (1/2 inch dip).

Chances are it'll be the same in the SGS4. The home button can do three things: short press = go home/wake up the device, long press = task manager, double press = voice control. The "delay" is a fraction of a second while the s/w makes sure a second press isn't coming. It's never bothered me but the solution is to disable the second press (kill launch voice control from the home button) in settings.

I'll bet you with the stock e-mail client, browser, and messaging client open that Sense 5 uses at least 1/3 more resources (RAM) than the version of TW in the SGS4; even with all the sensors on all the time. Sense is far heavier than TW and gets heavier with each concurrent app running because of the HTC Framework. Said framework is also why no HTC s/w or widgets function on other devices.
[Galaxy S 4 Q&A, Help & Troubleshooting] -]Megacharge[-:
Interesting, would you mind posting a link or two in here for us that explains how "Sense 5" works, and why exactly it's heavier, and showing how much it uses in comparison to the SGS4, it would be an interesting and educational read in addition to providing material to back up the comment.

[Galaxy S 4 Q&A, Help & Troubleshooting] neilmc1983:
One way to reduce the time going back to the home screen when pressing the home button is to go in to s-voice setting and untick 'Open S Vocie by double pressing the home key' This will speed up going back to the home screen

And you could reduce the animation scale in the developer options to 0.5x, this will speed up things

but to eliminate actual juddery lag, then there's no hope. touchwiz is slow. it will never be as smooth and slick as an iPhone or Nexus 4 etc..

[Galaxy S 4 Q&A, Help & Troubleshooting] SirCanealot:
I like the way nobody notices iOS pauses before doing anything. I'm far happier with android which does something instantly rather than background loading and carrying out all the animations at 60fps.

Seriously, most smart phone uses must never be able to play video games! Most current console titles don't even hit 30fps most of the time.

Does every have a gtx 690 sli so they can vsync 60fps 100% of the time?
[Galaxy S 4 Q&A, Help & Troubleshooting] MrAndroid12:
I kinda agree, but apps don't actually pause on ios. It just loads but won't update on screen while finger is on it.

It would be better if android had the option to pause some apps, coz often times I find some apps screwing up battery like an animal.

But yeah, android can't really play graphically intensive games casually without occasional slow downs and drop frames where as Windows phone and iOS platforms are pretty constant.

I played with the Galaxy S4 in a Samsung store today and the first thing I noticed was how laggy it was. To be fair, if it were any other Android phone I wouldn't have noticed, but I was kinda (maybe naively) expecting velvety-smooth performance from Samsung's new flagship. I don't know if they still have pre-release software on their display units, but I tried more than one and they were similarly laggy. Homescreen scrolling was no improvement over any mid-to-high range Android phone out there, scrolling through lists was not smooth and even the widgets had an unacceptable delay in loading.

I did notice tiny "Qualcomm LTE" stickers on the top of the phones so keep in mind these are probably not the octa-core versions.

I recently bought my mother an HTC One and to be honest it really is no contest in terms of fluidity and responsiveness. The Taiwanese phone is the only skinned device that comes close to a Nexus in terms of smoothness and perceived speed.

[Galaxy S 4 Q&A, Help & Troubleshooting] barondebxl:
The only area where the S4 is laggy is in the widget drawer. it has been an issue since the S3, however it isn't a Samsung issue, it's an "stock android widget drawer style" issue. The nexus 4 also lags in its widget drawer. Sense doesn't lag on its widget menu cause its totally different style than stock android.

Yeah, poor software. Although I must say, is it just me who or does anyone else notice considerably better performance on Nova over Touchwiz launcher? Or is it just placebo effect?

Could a better man than me please please EXPLAIN why there is lag?

I understand about software optimization and all that.....but we're on the galaxy s FOUR now. I mean, why is there STILL dialer lag? Are the software engineers stumped as to how to fix it? Does apple have some sort of patent on something in iOS that rids it off 99% of any lag?

I would love for someone to concisely explain this. Project butter obviously helped........but the GS4 is a powerhouse - what sort of processor will be needed for zero lag??? 3ghz? 10? I just don't get it.

As much as I hate apple, the difference is iOS users get excited about firmware updates because they bring new features, whereas the majority of GS users get excited because the new firmwares are fixing bugs and ui issues. Depressing.

Yeah that's the dialer lag - it's a facebook issue apparently. The UI lag though, is inexcusable. I personally think it's probably the exynos optimized code being ported to snapdragon or something.

Samsung phones have the slowest Dialer and Contacts apps on any flagship phone. I remember the S2, S3 and Note 2 being like this. They take 3+ seconds to load at times.

Unforunately it seems the S4 is no different in this regard.

Nokia's from 10 years ago loaded the contacts app quicker. For all the bells and whistles high-end Samsung phones have, it's a sure shame simple apps like this can't be silky smooth. And don't get me started on homescreen redraw!
