Same for me, but Android 4.3 has that lag too.

The MotoX patch doesn't solve the issue.

With ART the speed is amazing.

Hi.

Since i have updated my Nexus 4, my "multitask" button responds slowly.

When I want to navigate between apps' it takes somes seconds...

Have you ever see this bug/change ?

EDIT

: Is it the same problem that yours, with Davil/ART?

Thanks for your future answers.

EDIT 2

: I've juste configured ART and THIS problem seems to be disappeared. Waiting some others.

Email Widget Problems

I also am having a similar issue, I posted this in this forum a few days ago, my issue is I have an exchange and Yahoo email account, If I use combined unread widget it never updates, If I use combined inbox it will update when new mail arrives, but will not for reading an email or deleting it until new mail arrives.

Anyone else has connection problems on kitkat? Several google services don't work while on my home wifi, feedly doesn't load, play store has no pictures, but I can surf the web on chrome... Everything comes back to normal on 3G.
[Nexus 4 General] Astralero:
I have the same problem, and some pages like dailymotion or blogspot not work. If i turn to 3g all work ok and in another wifi too. I thinks is some issue or imcompatibility with some routers.
[Nexus 4 General] rpudner:
Maybe but I have a work exchange account and personal Yahoo both show in the widget.
[Nexus 4 General] Astralero:
Do you have 2 router? with this config?

inet ------------wifi.router-----------wifi.router2

Do you connect to the second router?

I have that setup and I've noticed that if I connect to first, everything works ok, but connected to the second, that's when it does not work well.

At first I thought it was some incompatibility router, and went to connect to the first router, to see that work properly change the order of the router but all followed the same. Connected to the second do not work a lot.

Sorry my poor english

Noticed a bug yesterday. I don't know if it's been reported already or not, but anyways.... I made a few calls that got rejected. Fair enough, but when I opened the phone app from the recents list, it still showed me the dialling screen for some unknown reason. It was not calling anybody, I just needed to press the big red button to get back to the proper dialler. It happened a few times.
[Nexus 4 General] scotth324:
Does this problem happen only once after you unplug your phone? I am having a similar issue. Unplug the phone and go out of WiFi and when data connects sometimes it constantly drops and connects over and over again until I reboot the phone. Never tried going and picking my carrier though. Will try that next time. Still a pain in the ass.

[Nexus 4 General] mymeatb18:
Are u using a custom kernel
[Nexus 4 General] Sfkn2:
Stock 4.4 Kernel.
[Nexus 4 General] Impo5sible:
Isn't it happen because of the "ok google" voice feature? Snapdragon S4 doesn't have the power save utility (or whatever does it calls) like snapdragon 800, so it might cause "bigger" battery drain.
[Nexus 4 General] mymeatb18:
Yeah for some reason when switching to Franco kernel I now have a Google search wake lock.
[Nexus 4 General] Sfkn2:
A lot of people are having issues with wake locks with Franco. Check out his thread on the forums.
[Nexus 4 General] manpildo:
Unlikely because for a wakelock to occur the phone needs to be in sleep. In sleep mode voice search initiation doesn't work either way.

[Nexus 4 General] Bliepo:
I flashed kitkat on monday and I must say I am quite satisfied with it. I am using ART and everything is working smooth for me, save an occasional hic-up. 5Ghz WiFi works fine for me, both at home and at my university. It also worked with 4.3. It's too early to say for sure, but I do believe battery life improved.

I noticed two bugs though, both related to email. I had a lot of crashes with the email app. It would crash almost every time I tried to open the app or received an email and it also crashed at random just about all the time. Turns out the problem was in the profile name I entered. I had a slash (/) in the name and apparently this was the problem (not discovered by me, I just googled it). Changing this resolved the issue and now e-mail works fine.

The second bug has already been mentioned and pertains to the e-mail widget. If you have subfolders in your inbox, you cannot select your inbox in the widget, like quoted below.

I did figure out a work-around though. It's actually quite simple. In outlook, I moved my subfolders to the concepts folder. Then I configured the widget and was able to select inbox. Afterwards, I moved the subfolders back to my inbox and it worked just fine.
[Nexus 4 General] RealiZms:
Anybody else notice "touch sounds" just works when they want to?

I actually like the touch sounds in Kit Kat(maybe it's a new thing lol) but they only work sometimes or rarely at all.

I'm just kinda stumped...system volume is up, don't get it.

I'm all stock, not rooted, with an unlocked bootloader KRT16S.

Did my camera just broke or is the camera in 4.4 really bad in low light conditions & with flash now?

I can hardly get a sharp image, like 90% is blurry crap.
[Nexus 4 General] The1Shark:
Well it seems to me that the KRT16S OTA screwed up in some way since the installation of the zip in the link below which is based on the KRT16S factory image solved the tethering problem.

As far as I understand, you can extract the system.img from the factory image and flash it via fastboot. ( you will lose root )

I used option 1 ( install zip from sdcard via CWM ).

No lose of data, tether works !

You will need unlocked bootloader + root and CWM or TWR

Problems with Phone APP

Might be a problem with the launcher, don't remember having this issue after installing 4.4

After making (or taking) a call, if I press the back button (call has already ended by the other person or me), the APP wont close. The red bar for closing the call will get gray (call has ended) after that the only way to go back or getting out of app is by pressing home button.

I'm stock, running Nova Launcher Prime 2.3 beta3.

In addition to massive battery drainage and some random freezing in chrome and google search I get Play Music to lag the sound when playing .flac files from internal storage. That's the one I just can't live with....

regarding to the drainage, I noticed that when I spend my day working at home, my phone is ice cold and it can stay for more than 20 hours without a charge, but when I go out it get's hot as hell a few seconds after I turn the screen on. So it's probably ill location reporting...
[Nexus 4 General] mymeatb18:
Battery life is much longer on WiFi. Bad signal could cause heat issues but I don't think location reporting should heat too much unless there is also bad signal. I keep location off.

I think I received the KitKat downgrade?

My Nexus 4 data speed on both At&t mobile and WiFi are roughly 60% of what they were prior to installing 4.4?

The color change for icon in the status bar is in my opinion, a step backward. Not only does the Wi-Fi not show data activity anymore but when you use the pull-down quick setting display the arrows next to the icon are barely visible but they do not serve a purpose. When tx or RX data you would think they would reflect the activity. Mine just sit there, useless.

Do any other devices have active arrows next to WiFi or mobile data? What did they put them there for, intimidation?
[Nexus 4 General] maslelviz:
I have hypothesis that the battery drainage is depended on Play services. I did a full wipe but my battery didn't improve. Then I uninstalled Play services updates and it become much better!! Though, I was unable to use some of the features, so I installed this manually https://drive.google.com/file/d/0B9VVbUsFgymmMEtQblhJXzJQZzg/edit?usp=sharing

I'm not sure what it is, but I found this version of Play Services .apk on Android Police website together with google experience launcher. I don't use the launcher for the sake of experiment now, but this version of Play services has been flawless to me. (11h 32min on battery, 2h 41 min SOT, played some music for 2 hours and still 24% left)

The Chrome refresh bug is driving me nuts. My Motorola Cliq held tabbed pages longer than Kit Kat.

I have another question that's more of a general inquiry than anything. Why is it that this is the only bug I experience, whereas the others people have mentioned I don't get? Is my device special or something? Or am I just lucky? Are the updates different for every device?
[Nexus 4 General] Jazavchar:
I don't know dude... it seems that bug is sporadic and not everyone has experienced it. On my device, while KitKat definitely uses less ram overall, the device still manages it nicely, filling and freeing the ram as needed. Sometimes it goes low as using only 800 MB and other times when I load it up it will fill up to 1.2 or 1.4 GB. Chrome seems to hold tabs in memory until I swipe it away. Have you used some custom kernels on past builds?
[Nexus 4 General] monkor:
Interesting. And nope believe it or not, despite owning a Nexus, I've had so many skins over the years that I just want to enjoy stock for as long as possible. Still loving it after two months of using the phone too.
