Correct. So far any Android device lags. Any phone, any tablet, all of them. Sure, we are lucky to have one of the more lag-less devices but anybody who says the SGS2 doesn't lag at all either:

a) is ignorant

b) is very easy to please

c) is blinded by Android fanboyism

d) hasn't seen a true lag free device yet.

The SGS2 lags. Sometimes a little, sometimes like crazy, so be it. Don't claim otherwise.
[Galaxy S II General] Vash:
Yes, my old xperia x10 lagged all the time. But my custom-ROM-running sgs2 doesn't lag. Yes, I've had an iPhone 4 for 8 months so I can compare them.

IMHO, lag is mostly placebo and expecting too much these days. Ugly code can cause the UI to stutter on every platform, including iOS.

[Galaxy S II General] Fizzerr:
LOL. You must have a heap of bloatware on that thing. Either that or you've flashed a dodgy ROM. I get no lag at all. I think you are getting lag confused with app loading time. If you fire up Asphalt 6 and it takes 10 seconds to load that's not lag. Have a play with a Galaxy S on one of the earlier ROM's. Then you will see lag.
[Galaxy S II General] Pfeffernuss:
No bloatware whatsoever.

Tried many many Roms, many many kernels, many many Launchers, etc. All the same thing. The phone will once in a while lag and/or show micro-stutters.

None at all, really. A statement like that makes all the other things you say worthless. Every Android device will once in a while lag and/or expose micro-stutters.

I know what lag is, thank you.

It's exactly the same as when people say "my screen is perfect. I have no yellow/darker left side on my panel". When you check it yourself of course the panel isn't even. Usual reply? "Well, I don't see it so it doesn't bother me". That's not the point, it's there. The fact that the phone is 100% smooth for you is nice, only it is not.

Your SGS2 also will have occasional lag/micro stutters. In all apps/all the time? No. In most apps/usually? No. In some apps/occasionally? Yes.

Is it still an amazing phone? For sure. Probably the best/smoothest Android so far? Guess so. Does it sometimes lag and/or stutter? Absolutely.
[Galaxy S II General] mariosraptor:
This is all bulls**t. Remove all bloat that are on your S2 and see the difference. Iphone has no bloat by their networks that provide this stupid phone. Ics will make use of better hardware but you will see that more low end android phones that will be updated to ics will compete more efficiently with ios devices. Cheers and if you do not like Android please don't buy it.

The Galaxy S2 does lag at some point, but some people eyes are different, some consider it lags some doesn't. Thats why you see people able to play games at 20fps on computer but you'll see people complaining at that framerate.

iOS is a lot smoother than Android regardless if its Ice cream sandwich or not the priority process is at 'normal' not real time like WP7 and iOS. Although you'll still see lag on iOS and WP7 but less than Android.
[Galaxy S II General] ithehappy:
iOS is definitely got a smoother UI than Android, doesn't matter if anyone not accept it.

Besides, I don't wanna hear why Android would be slower or more laggy than iOS, are Android devices less costlier than iOS?

Nonsense.

The SGS2 is definitely the smoothest android device I've ever used, but to be honest, yes it sometimes does lag / stutter. If you say otherwise, then you're kidding yourself - but to be fair, it is generally pretty smooth.

Mind you even the iphone 4 lagged a bit at times (not sure about the S).

The Noka Lumia 800 I used in a shop was definitely smoother than the SGS2 though, that thing was just unbelievably buttery smooth.

Mind you its horses for courses; neither iOS or WP7 have as much functionality or ability to customise as Android.
[Galaxy S II General] kocekin:
SGS2 is pretty smooth, especially compared to some other Android devices that I checked out.

But it's not as smooth as iPhone 4 (therefore 4S) and it sometimes bugs me.

Not a huge deal though.
[Galaxy S II General] blueseeker:
Want to see Android lag ? Get the first SGS.

The lag and stutter prevented me to buy an android until SGS2 arrived.

iOS doesn't lag because it doesn't do sh!t! You have a bunch of icons and some animation transitions. That's it. There are no 3rd party services or apps running in the background.

Android has more UI layers to render. Of course, it lags or stutters from time to time, but only when there are some I/O operations on the background (like updating some market apps). The experience doesn't even compare with the first SGS.

Make no mistake, this is the best Android device to date.

You know why the random stutter or lag doesn't bother me ? Because everytime this happens I'm thinking how much things I can do with my device. There's virtually no limit. And if this is the price I have to pay to do all that, so be it. I don't even want the ICS release that badly, because now after some modding, I'm happy with all of the features I got :)

I love this phone!
[Galaxy S II General] jonny68:
I disagree, my own phone has absolutely no lag whatsoever and is ultra fast with no lag whatsoever, my mate has a iPhone 4s and it's still not as fast or smooth as my own phone, he may even grudgingly admit it someday too;)
[Galaxy S II General] dinan:
This is the truth. 15 year-olds that come on here screaming their phone is lag free and better than the iPhone are just fanboys.

The SGS2 is the smoothest and least laggiest android phone I've used, though. It still lags occasionally.

[Galaxy S II General] aydc:
I've been using my SGS2 for more than 6 months and I don't think I've seen it lag even once. Everything seems to happen instantly. Lag is definitely not a problem.

What's much worse is the smoothness. During screen transitions, you can almost see frames as they are being drawn. If iPhone's interface works like a 100 fps game, SGS2's interface works like 15fps. That's what's annoying.

Some things help, like using small and stationary wallpapers, not too many widgets and using only TouchWiz as a launcher, which seems to be the smoothest one. However no matter what you do, it's still not going to be as smooth as an iPhone 1, let alone 4s.
[Galaxy S II General] barisahmet:
I have a SGS2 and it is much FU**ING more faster than iPhone4 in browser, in apps whatsoever. I suggest you; go buy an iPhone if you will watch your phone's smoothness when transiting between homescreens (even though I think Touchwiz is as smooth as an iPhone homescreen which CAN'T have widgets(!)).

Comparing phones by only homescreen transition smoothness is just not fair. And SGS2 is definitely faster than suxPhone casual/everyday in-app usage, like web browser etc. Period.
[Galaxy S II General] sidepocket:
Ironically, I left my iPhone 3GS for a GS2 because the iPhone was way too laggy. Go figure.
[Galaxy S II General] aydc:
This topic is about UI smoothness. What else are we going to compare? Should we compare phones weight, size or color in a topic about UI smoothness? LOL...
[Galaxy S II General] ithehappy:
I thought only iPhone users are biased, before this thread ;)
[Galaxy S II General] barisahmet:
I meant that you can compare web browser UI performance but, you need some IQ to understand that. Well, nevermind.
[Galaxy S II General] tameracingdriver:
As I've already said, its not perfect, but that is blatantly untrue.
[Galaxy S II General] jlevy73:
Did you really just compare to the 3GS to the SGS2 :eek:
[Galaxy S II General] dinan:
What many seem to not understand is the difference between SPEED and SMOOTHNESS (and also responsiveness).

Imagine that the iPhone (1st gen, or 4S doesn't matter) and android displayed a dot where your finger contacted the screen. When you scroll around on iOS you will never see the dot because it's always directly below your finger whereas in Android it has a slight delay which would make it seem like the dot is "chasing" your finger around. That is responsiveness.

Smoothness is another thing iOS (and even WP7) have perfected. They aim to maintain 60fps throughout the UI at the expense of longer loading times (why do you think you can't turn off transitions in iOS?). Even simple things like scrolling through the settings menu in android will sometimes stutter. If you scroll through it 1000 times I guarantee you at least 1 time it will stutter, which isn't the case with iOS. There are a few occasions where I've seen iOS stutter but those were jailbroken phones with extra "tweaks" that probably weren't coded very well.

Speed is just merely the time it takes to perform an operation. I will admit that the iPhone is slow. It's smooth, but it's definitely slower than my SGS2, although it looks good while it's being slow. I can open apps faster, load pages quicker, multitask faster, etc. I'm willing to wager a sizable percentage of the time spent using an iOS device is wasted by waiting for those silly animations and transitions. Again, this is actually an effect they use to "mask" loading times to make the phone seem buttery smooth. On my android phones I usually turn animations to "some" or completely off which makes it feel much snappier.

So in the end, responsiveness is the time it takes to register your INPUT. Smoothness is how it transitions from one operation to the next. Speed is how fast the phone performs your command (after it has recognized your input, which again, depends on responsiveness).
[Galaxy S II General] androidkid311:
You have an amazing GS2 lol :D. Iphone 4s is more smooth... speed wise... it say they r the same...ish lol. But u can never be truthful and say GS2 is smoother than a iphone 4s. Im a die hard android fan but u gota b honest at times. Lool. :-P
[Galaxy S II General] MrPhilo:
You must have never owned a iPhone before. From iPhone 1 to 3GS you'll defiantly see it lag more often than Galaxy S2 despite Apple cutting support for them.

From anything higher than iOS v3.0 is when you see less lag on the iPhone 1 to 3G. They all use a ARM11 CPU which is like the worse ARM CPU ever! Only 3GS is a tad better due to the Cortex A8 600Mhz + SGX535.

At the end Android will only be smooth or similar to iOS & WP7 when it has hardware acceleration + real time process. They have achieved half, now we need someone to create an app to enable real time process than normal.
[Galaxy S II General] lanka93:
While i can confidently say that my S2 doesn't lag, my dads 4s has noticeably smoother scrolling.
[Galaxy S II General] gerryjoson:
Good post, I agree
[Galaxy S II General] blazk:
^this

is the right answer
[Galaxy S II General] jaykresge:
You hit the nail on the head. The speed you're referring to is input latency, or how long it takes for the screen to recognize that you are touching it. There was an article awhile back about music-creation apps (like pianos and such) and how the huge input latency difference was a killer for Android.

http://www.musiquetactile.fr/android-is-far-behind-ios/

As for the fluidity (smoothness), you're also correct. Android has more going on, whereas Apple and MS do a better drop of hiding things. A good example of this is when iOS5 introduced the notification shade. This requires a higher fill-rate. My wife upgraded from an iPhone 4 to a 4s, and on the original 4, the shade had a huge amount of lag. On the 4s, it's incredibly smooth. This wasn't designed with the 4 in mind.
[Galaxy S II General] aydc:
Whatever the reason, Google should solve it. SGS2 is almost as fast as a laptop and it costs as much as an iPhone. There's no excuse for laggy, slow, stuttering UI. I'm sick of saying "Damn!" every time I play with my friend's iPhone 4S.
[Galaxy S II General] jj03:
i have very ocassional lag, but to be honest, its generally silky smooth. i'm running ki3 with chainfire kernal (rooted) with all bloatware removed. i love the overall ui of android and indeed, the gs2 as a whole. its just a superb device.

.
[Galaxy S II General] godutch:
I have literally reported dozens of bugs relating to smoothness on linux(ubuntu and mandriva), x.org, opera on linux, kde, nvidia driver, compiz and other software, complained and nagged the devs to death, so you know I am fuzzy about smoothness but I have no complaints with android, even on my htc desire scrolling was buttery smooth(in fact I was so much surprised to see smooth scrolling working smoothly on my desire after all the misery I experienced on linux (as well as proper font hinting)) and fast and response immediate.
[Galaxy S II General] kickassdave:
Sorry but some of the bs here is p*****g me off.

I LOVE my SGS2 and I love Android, but trying to say you've never experienced a laggy UI is just total lies. I've tried every single custom iteration of Android you can and there is always some lag experienced somewhere, it doesn't bother me that much, but it IS there and it IS annoying.

The hardware accelerated Touchwiz framework of normal stock mofied roms seems to be the smoothest experience you can get but even then lag still exists. No point in arguing about it.

I agree this sounds like the grunts of a disgruntled employee, but it makes sense, and it makes me sad :(

Unfortunately for iOS they don't have the absolutely awesome what seems like availability of cuatomisations on Android and that's what keeps me going.

Android for life :D
[Galaxy S II General] Hrithan2020:
Ironically, despite the huge performance difference in hardware [probably at least 5-10x faster, in terms of h/w], the scrolling performance of 3GS is better than SGS II, sometimes.. [maybe when GC is running? ]

If you compare, Windows Phone 7 or iPhone 4S, it simply can't keep up in terms of fluidity. Doesn't really bother me in case of SGS II, as it is damn fast. But, for the older [near iPh4 hardware] android phones, it is annoying.
[Galaxy S II General] Fizzerr:
Sorry guys but I just don't believe the Apple fanboys who come on this thread and say the sgs2 has lag. I have NO lag at all. Maybe some of you guys need to flash better ROM's.

Cheers.
[Galaxy S II General] Pfeffernuss:
While I absolutely love my SGS2 and wouldn't want an iPhone for free the fact remains the Samsung isn't 100% lagfree and 100% smooth. Like every Android device up to this date. They all stutter sometimes (or some devices a lot). They all lag sometimes (or some devices a lot). So what. It's a fact.

Yes, you do have lag, occasionally. And the phone isn't 100% smooth, occasionally. Has nothing to do with the Rom, kernel, governor etc. So if anybody is talking like a fanboy it's you. Be rational.

Yup, drink some more. Will make the phone even smoother: win-win situation!
[Galaxy S II General] GIR:
This article is a load of horsecrap! The UI lag is a load of horsecrap! This guy is just an intern, a student who thinks he knows best IF infact it is true he interned at Google. Who is he to criticize people who have proven their worth? "I know they'll get it eventually", yeah go F yourself buddy!

First of lets start with the obvious. How does he have any knowledge about the inner workings of iOS? He doesn't so it's impossible for him to make a comparison.

The Android isn't as smooth as iOS myth is a load of horsecrap! It's only since the 4S that the iOS UI has become stutter free, even on my 4 I can notice some stuttering. You can test this yourself on a 4. Have appmenu of 4 or 5 pages, goto the end of the menu and then press home, let the lagging ensue! The 4S doesn't have this problem because of it's dualcore.

Okay so those are the latest and greatest from Apple but what about older devices? What about the 3G? Nobody talks about that one. The slowpoke of the family. You want lag? Go buy yourself a 3G. 3GS? A bit better but slow none the less, keep in mind that the 3GS is still on sale in most parts of the world.

So where does this lag nonsense come from? It comes from people with no idea at all and no money to actually buy and try all these devices who have to keep yapping on about things they know nothing about. It comes from Apple fanboys who see their all mighty icon being crushed before their very eyes but to protect their own ego they have to make nonsense remarks like this: "Yeah my iPhone is better because it doesn't lag, boohoo", as if they have any clue to whats going on, as if it matters that there's a slight hiccup in the eye candy, as if that is what defines a superior device!

It comes from people comparing low-end android devices (like the Wildfire, Galaxy Ace, etc) to high-end devices like the 4S or S2. Oh here we have a Galaxy Ace with a low-end processor, 278 MB RAM and no flash memory which only costs 150 euro's. Oh no! Compared to this other high-end device which has 10x the specs and costs 6x more it is lagging! Crappy Android!

Android does not lag. There used to be a problem with Android 1.x and 2.1 but that's fixed and now my S2, Sensation XL and my 4s all have nice and lag free eye candy. On the other hand my Galaxy Ace, which I still use when I have to work in a dirty environment, is a piece of crap!

Don't believe this nonsense which is being propagated by people who have no idea at all and somehow have to need to yap about it just so they can act, look, feel as if they know something as in fact they know nothing!
[Galaxy S II General] PatrikS:
Thanks GIR, i thought for a moment that i was hallucinating when i often see friends 3GS / iphone 4 lag when they use them.

They are as a fact not lag free and i dont understand why that never comes up in discussions.
[Galaxy S II General] TheSniperFan:
This thread is so full of fanboy's.

People dumb enough to compare the iPhone 1 with the Galaxy S2 in terms of smoothness. Seriously!

The Galaxy S2 overpoweres the iPhone, but you ignore that fact. Look at the older Android devices. Compare the smoothness of the HTC Desire to the iPhone of its time and you will notice that it wasn't THAT smooth. I say "THAT smooth" because many fanboy's here think that what this guy says means that the device is a useless piece of lagging crap if it uses Android. But he just says that laggs occurs more often. NOTHING more!

I had chances to use various iOS-devices and WP7-devices and their UI's were mostly smooth. They had laggs to, but not so often.

Android got better and better with the time. And now I'm unsure whether Android became so smooth because it got better, or because the Hardware got better.
[Galaxy S II General] GIR:
Yeah the Desire and the 3G come from the same era... and that phone wasn't THAT smooth either.
[Galaxy S II General] xEraseRx:
The Galaxy S2 does lag, it really is just a little bit so I do not really care, BUT these slight stutters are enough to make the interaction with the device seem "unnatural".

What I mean by "unnatural"?

It does not give me the impression of interacting directly with the content shown on the display, the touchscreen as a medium is always clearly perceptible.

I do not know if iOS handles this better, as I did never own an iPhone. But from my impressions from the the store it does.

Overall I still took the GS2, as it, at least in my opinion, is the better phone.
[Galaxy S II General] godutch:
The desire, sgs1 and iphone 4 are all 2010 phones.
[Galaxy S II General] TheSniperFan:
Desire HD, SGS, Nexus S & iPhone 4 are from the same era. The Desire was one era before with the Nexus One and the 3G.

The Desire HD is much more powerful than the Desire and so is the iPhone 4 when compared to the iPhone 3G.

You know what gets me the most? This guy claims he interned at google, so obviously he knows a thing or two. He has some critique towards Android... Okay. But Android is opensource, so if you know better why not do better? make a distro with all the improvements to show them how its supposed to be done and to give us a better device.

But no, instead of doing that he had to talk out his ass.

3. speed (fast, slow).

It really doesn't seem like people are on the same page.

ps. To the guys that clear ram religiously, you are the reason why your phone feels slow.

you need some more IQ to use Android. and if you have some more IQ already, you should know you are interacting with a touchscreen on your phones screen. that simple, get over it. stop saying «I have a feeling that I am interacting with a touchscreen omg»
