On the iPhone it's almost instant whereas on Kitkat it's quite laggy.
[Nexus 4 General] ashishv:
Switch to ART and see the lag gone.
[Nexus 4 General] terryhau:
Yep, it's because of the double tap command, not the same issue as this.
[Nexus 4 General] snapper.fishes:
You are right. The delay is quite noticeable.
[Nexus 4 General] zorginho:
Try to switch to GEL and see if the issue is still here.

[Nexus 4 General] RealiZms:
It will go away. New update needs to settle. Overreacting bra...

There's always been an occasion where one of the buttons may stay lit slightly longer. However whatever function is not delayed, always immediate...

If your issues are that bothersome i would do a full wipe and a clean install. Sometimes it may just be a bad app or crazy power hungry app too.

Just some things to consider man.
[Nexus 4 General] monkor:
I say again, it's the stupid animation that probably masks load times or something. Observe the home button when you press it. It lights up, then fades to black and voila, you're back on the home screen. Just because you turn off all transition animations doesn't mean they're all gone. They are all over the OS.

And this is about Kit Kat, so if there's so so much of a difference from the time frame in 4.3 on the Nexus 4, which is what the OP claimed, then document it. Otherwise I'm just calling placebo effect. And since the burden of proof isn't on me, I'm saying It looks the same as 4.3.
[Nexus 4 General] forever_lol:
I am sorry, I know how people feel when somebody cannot see the same issue on its device. Unfortunately I am one of them. I really cannot see this lag on my handset. Full wipe (including userdata wipe) + rooted stock + ART. I must also say that stock launcher is imo even smoother than GEL now!
[Nexus 4 General] XupModz:
Could you share the apk please?
[Nexus 4 General] rasengan82:
I can feel the lag as well.... For people that don't feel the lag...did you guys full wipe? Remember that the phone is always fast and snappy after a full wipe...
[Nexus 4 General] forever_lol:
That's true, but why wouldn't you do that? It's just 15 minutes longer (in order to backup sd card and copy it back)
[Nexus 4 General] rasengan82:
The thing is, the phone will eventually reach this point again after weeks of use.
[Nexus 4 General] forever_lol:
Again cannot argue with that :) However I prefer to do the full wipe bcos at least you'll know that dirty flash wasn't responsible for that issue.
[Nexus 4 General] anto.danny:
i can totally see the delay..the op is right
[Nexus 4 General] Pouzito:
Yeah, i'm also having these lags. Updated from stock unrooted 4.3 to stock 4.4. I'm using GEL.

And i did a full wipe before flashing, so i'm kinda thinking of going back to 4.3 and waiting for the OTA...

Also, i can't accept any calls if i'm already in another one. It just freezes my screen a bit and continue ringing as if i did nothing :p
[Nexus 4 General] nicholasbgr:
OP is not crazy. I have the same issue and some folks from reddit too. Also, like someone already mentioned, switching apps with the multitasking menu is a bit slower than on 4.3 too.

One thing that is important to mention is that this lag/delay or whatever you wanna call it is only present when using Dalvik. I think this is why most of you folks are not experiencing since you guys seem to be using ART.
[Nexus 4 General] eksasol:
Just download the CM11 from here and extract it: http://fitsnugly.euroskank.com/?rom=cm11&device=mako

But I think its switching to ART that help.
[Nexus 4 General] shankesh:
I'm having lag while taking snaps in stock camera app.... Even in normal mode not in HDR Mode
[Nexus 4 General] wilsonlam97:
lol dat placebo though

The only lag I want fixed is the camera lag. IT'S SO DAMN SLOW.
[Nexus 4 General] anto.danny:
its slow on nexus 5 as well
[Nexus 4 General] defffizz:
I experienced it with dalvik, i switched to art and now its smooth :)

Nexus 4, stock 4.4
[Nexus 4 General] morgante:
I will try switching to ART tomorrow and see what happens. Haven't noticed much home button difference between AOSP launcher and GEL on 4.4 with Dalvik.
[Nexus 4 General] activexda:
Yes I have the same problem

But I think the problem is from the Google experience launcher itself!

Because I'm running stock 4.4 on my nexus 4 and it happens only when I use GEL. And by Switching back to the normal jelly bean launcher, there was no problem at all.

(I also noticed the same issue with nexus 5 port ROM)
[Nexus 4 General] 433Mhz:
Is anyone else experiencing this lag when pulling down and afterwards pressing the notification bar?

http://www.youtube.com/watch?v=RtIeuYgdLFw

Not my video but it lacks even more on my phone.
[Nexus 4 General] Danny.ns:
Yes, i have the same 433mhz, even worse than in video. Others have confirmed this issue as well.
[Nexus 4 General] The Zel:
ART is great, I can even see a difference in facebook! Scrolling is so smooooth!

[Nexus 4 General] morgante:
Home button lag seems to be gone with ART. Recent app switcher is also noticeably more responsive. Will be keeping an eye on how it behaves over the next few days, though the app incompatibilities with ART as it is today are unfortunate.

Running stock 4.4 and tried AOSP launcher, GEL, and Nova. I notice very little difference between them as far as home button responsiveness goes.

[Nexus 4 General] nickos23:
no problem for me, after I updated google search and installed GEL, using dalvik cache.

I had some lag with the stock jelly bean launcher, but now everything is normal. I guess home-button lag has to do with the launcher used.
[Nexus 4 General] terryhau:
After having the phone on for about 2 days, its stopped doing it.

Pretty weird. I'll see if it comes back.

edit: It seems to come and go.

The app switcher delay is still there. When pressed while inside an app, there's almost a full second of delay. Not as much when pressed on the home screen.

Tested on 4.3, and it was definitely not this way.
[Nexus 4 General] Jz Chong:
I dont really feel as much as one second delay inside app as you said but im on custom 4.4 rom though.
[Nexus 4 General] arffrhn:
Tried pressing home while in app and pressing back to close an app. There is slight delay in both ways. So it is not because the home button..the time taken for the app to close itself is the culprit. Having that said..it really is just a slight delay though. Not a big problem.
[Nexus 4 General] MoneyNotEnough:
Are you running ART?
[Nexus 4 General] arffrhn:
Not yet. Still running on dalvik here.
[Nexus 4 General] mr.pedro:
I have Nexus 4 with stock 4.4 android and GEL. I experience both- home button lag and lockscreen notification bar lag. After switching to ART instead Dalvik, the home button lag disapper, but there is still lag on lockscreen when I am pulling down notification bar. This lockscreen lag is present on GEL and AOSP (Jelly bean) launcher and is more annoying then home button lag.
[Nexus 4 General] Google86:
not happening to me . i did full wipe

Sent from my nexus 4 running 4.4 kit kat
[Nexus 4 General] mr.pedro:
I have done fullwipe too...
[Nexus 4 General] atulalvenkar:
After reading all comments here, looks like the lag happens only when transparency is enabled by the launcher. Hence Nova/GEL have the lag and stock 4.4 launcher does not.
[Nexus 4 General] anil76:
+1. Facing the same issues. I am on stock 4.4 with stock recovery.
[Nexus 4 General] Rempty:
I have the factory image + art and 0 delay so smooth
[Nexus 4 General] opssemnik:
on art is smooth, but the problem is with dalvik.(the problem is not dalvik,no problem here on 4.3,but i get lags on 4.4).
[Nexus 4 General] theadamsegal:
My home screen button is not working at all

My home screen button is not working at all. Back and Apps buttons work fine.
[Nexus 4 General] handols:
I used to have this lags but now its gone. Running rasta + latest franco + dalvic
[Nexus 4 General] Salty Wagyu:
Experiencing this Home button lag on Nova and Stock launcher as well. Noticed it before coming across this thread - so no external factors planted the idea in my head or any placebo effect. App Drawer to Home is instant, this is what it should be like from an App to Home.

This is a clean factory image wipe, and using Dalvik.
[Nexus 4 General] lowrider262:
The more I use 4.4, the more I'm noticing this. Seems to be getting worse with time also
[Nexus 4 General] omer7:
I have a big lag/delay in recent apps key. Not sure am i the only one having this issue.

As far as home button lag is concerned, it is there bt not as big as recent apps key lag.
[Nexus 4 General] opssemnik:
all gone on lastest 4.4 for me, try to update it.
[Nexus 4 General] sonikk4ever:
Going to confirm the lag as well, so yeah op is right
[Nexus 4 General] schmolch:
Just got the 4.4 ota and now i have it too. Feels like a whole second, definitely a lot slower then on 4.3. It is also a lot slower then on my n10 which struggles with gel. What a **** update.

Wow this lag even applies to other launchers which used to be lightning fast. Wtf is Google doing, bunch of retards. Unbelievable
[Nexus 4 General] SlasheI2:
I'm also experiencing home button lag + lockscreen notification lag. Not only that, I'm noticing lag when hitting the recents button as there is delay before it opens up. Scrolling performance is also worse because I see stutters every now and again. So far stock kit kat is making my phone feel like my Galaxy s2 running on gingerbread. The overall experience does not feel buttery like it did when the phone first came out.

I thought updates were supposed to improve phones but apparently they just push you to buy the newest hardware to keep up.
[Nexus 4 General] dethrat:
Still think it's your imagination can't say I've ever had a single lag.

The lag could only exist when your phone is used in a certain way after all I'm still in the habit of killing apps when I'm finished.
[Nexus 4 General] forever_lol:
I believe that people experience this lag, but I cannot understand how can anybody claim that scrolling performance is choppy on kk, especially with ART. Scrolling is freakin awesome here! You must try really hard to notice any frame drop, any slight stuttering in app drawer which was evident in every jb release.
[Nexus 4 General] ashwathravee:
Try this workaround for the notifications bar lag. It worked for me and a few others.

https://www.youtube.com/watch?v=FOLghNoqbKw&feature=youtube_gdata_player

Note that it is important to remove the clock widget and manually add it again from the list. Locking the screen to let your system do it automatically doesn't seem to help. Try it and see. Hope it helps.

As for home button lag, I'm not seeing it at all. I generally use ART but I switched to Dalvik to check. No problems whatsoever.
[Nexus 4 General] mananbond007:
Got an update to S...I too experienced the issue with aviate... But it smoothened it out few runs... ART is buttery smooth... Lag free absolutely ...

Sent from my Nexus 4
[Nexus 4 General] lowrider262:
ART definitely helps with the home button lag...
[Nexus 4 General] badboy47:
Not sure why some people have lag issue. I been running kit Kat for over a week now; running very smooth with zero lag. I never tried ART; been using dalvic.
[Nexus 4 General] activexda:
If anyone still interested, I flashed Franco kernel r194 for kitkat and now I'm using dalvic without having the lag issue :)
[Nexus 4 General] sriraviprasad:
Felt the lag ( Delay) initially while using home button and recent apps button. But now it feels okay after using 5-6 hours.

Only slight delay while using recent apps button.
[Nexus 4 General] xxdawidxx:
Well, if you wanna get rid off the home button lag go to developer settings and change Transitions Animation Scale to 0 or 0.5

If you change it to 0 it will completely get rid off the home button animation but it also will give very fast response to the hone button
[Nexus 4 General] bellasahbella:
got ota 4.4 yesterday. I found this topic because I have the same problem. tapping on the multitasking icon is just frustratingly slow. takes sometimes 1-2 seconds before starting the animation.. feels like I'm using a galaxy y or something.

---------- Post added at 10:07 AM ---------- Previous post was at 09:35 AM ----------

update.

switching to ART fixes it! it's as snappier as before now yay
[Nexus 4 General] anto.danny:
do any of you fell delay when swiping to camera in lockscreen?
[Nexus 4 General] Next123:
Im experiencing this issue at the moment when I just upgraded to the 4.4 build. I am looking to flash it to the purity tom to remedy this problem hopefully.
[Nexus 4 General] homebase2112:
Thank you, this helped tremendously. Searching Google for this issue led me to this topic. Nexus 7 (2nd gen), worked well on 4.3, 4.4 upgrade showed substantial transition lag. Your tip fixed the problem.

Thank you!!!
[Nexus 4 General] KSLevel11:
Do you have also lag while pressing multitasking button? "back" and "home" buttons are smooth, but the multitasking button have something like fps drop.

Do yo have that problem, or is it just my case?

EDIT: I read this thread, and it seems, that I have also stuttering animations of these buttons - HOME nad MUTLITASKING.
[Nexus 4 General] Richieboy67:
I ended up having to do a clean flash due to issues running ota. Everything seemed fine but when phone started I got a query aging me if I wanted root fixed. I said yes and that was it. Boot looping.

Anyhow, with a clean flash in getting no lag anywhere so far. I user Nova Prime, rooted, etc.

If you are getting lag it could be background syncs or apps. That would be where I would look first.

I tried animation fix as well, but after I set it to 0, I put it bak to 1, and seems like the lag is still gone...
[Nexus 4 General] raul6:
Interesting it seems that just setting the animation helps with the lag. Just need to see when it returns

Anybody tried the setup wizard suggestion? And how to even trigger that?
[Nexus 4 General] urfel:
If you are using launcher that supports shortcuts for activities, just create a new shortcut mentioned as second way in the article.
[Nexus 4 General] TwistyValhalla:
I use nova but can't find how to create setup wizard activity.
[Nexus 4 General] urfel:
Just do a long click on home's screen unused space, and choose shortcut from popup menu. Than choose activities, and find appropriate app and choose one of it's activities. Let us know if this fix worked :).
[Nexus 4 General] TwistyValhalla:
Thanks. I just did it but it doesn't really help with the laggy buttons. I think it only works when you have a non working home button.
[Nexus 4 General] urfel:
That's a pity. I switched to ART, and seems like it helped with the lag, though I don't really like this solution. I'd rather it was fixed by google.
[Nexus 4 General] raul6:
The lag is getting progressively worse with every day. No fixes help anymore. Moving to art might be the last thing to do as otherwise phone is unusable at times
[Nexus 4 General] SlasheI2:
I switched to art which has effectively killed the lag issue for me. Now everything is snappy like when I just got the phone.

[Nexus 4 General] Madfysh:
Tried both 4.4 builds O and S. Both flashed clean way. Using stock, no custom launchers.

Didn't have any lag on home button. So it's not down to 4.4.

Only lag i have is recent application button, but that was also in 4.3.

So its possibly ether because of dirty flash or you are using some custom(not stock) widget. Though I also use custom widget for weather.

Bottom line is, no lag on home button in stock 4.4.
[Nexus 4 General] RealiZms:
I'm in agreement here.....This thread is pretty entertaining though....All these people at the end of their rope over a problem that just isn't there. I'm using ART and even the Recents button is now butter. If I had any of these problems I would do a full wipe and flash the entire factory image.
[Nexus 4 General] urfel:
Cannot agree with you. I was on stock 4.3. No root, no unlock, no widgets on homescreen, even all apps I have were directly from Play Store. I got 4.4 throug OTA without any issues (whole point of it is to save everything, so no wipe), and I had this slight stuttering and delay on home and recent buttons. Did not have that on 4.3. It's gone on ART. Maybe there is something wrong with upgrade process on some systems.
[Nexus 4 General] RealiZms:
I upgraded the same way and have none of the issues you mentioned. Nothing but butter everywhere......I'm stock, not rooted using Nova Kit Kat.
[Nexus 4 General] Madfysh:
I agree with you that point of OTA is to keep old data. But, experience so far, thought me that clean install is a way to escape eventual problems.
[Nexus 4 General] urfel:
I agree with that. Before nexus I had S2, and I had been switching roms all the time, everytime with full wipe. But now I stand strong by stock and unwiped nexus :). If the trick with switching to ART didn't help, I would have propably lived with lag until solution would come up.
[Nexus 4 General] defffizz:
On ART, everything is buttery smooth. Switch to dalvik, and you will see the problem. I did a full wipe and flashed entire factory image (KRT16S), and multitasking lags pretty bad.

You are lucky,seems yours lags very small, I googled for the lags about switching apps. Btw my watsapp not working under ART.
[Nexus 4 General] urfel:
Maybe google thaught: "noone will want to use our new experimental ART because it's still beta, let's make them do that by adding some lag to home and recent buttons, which can be fixed only by using it" :D
[Nexus 4 General] Flirtino:
Same problem with whatsapp and ART. Worse, I couldn't reinstall it even on Davlik because of error 24. Had to do a full wipe!!! Still I get the lag and I noticed it too hence searching and finding this post. It was butter smooth on ART until I realised whatsapp doesn't work under it (well documented on the net)
[Nexus 4 General] Syncd:
Yeah, it's hardly noticeable, probably because i didn't wait for the OTA upgrade and flashed the factory image.

But i notice what the OP described: there's a difference between hitting "back" and "home" in an activity, and there's no good reason for it.

Loading a bloated Java app will always lag. Ever seen how every single Java app takes 30 seconds to open on a 3Ghz quad-core PC?

On Android developers rarely bother to do the initial loading on background threads. Instead all the initial loading of the app and layout inflation etc. will be done on the UI thread which makes the whole phone freeze for 1-2s and the home button command will be queued up till then.
