Switched back to dalvik to see what it feels like, because I switched to ART as soon as I flashed the image.
[Nexus 4 General] user822:
I also switched to ART now.

Some Apps not working and a little bit faster. I am not yet impressed!

But if it works a little smoother right now, I can only imagine the possibilities of ART on my next device when it is more optimized.
[Nexus 4 General] bladebuddy:
Does that mean possible xposed framework also ?

Art made my system pretty unstable, chrome browser froze a lot etc, freezelag here and there :/ stock unrooted
[Nexus 4 General] sayogs:
what is conclusion ????? should we people use ART or not?
[Nexus 4 General] BoneXDA:
If you don't mind messing with apps and stuff all the time then why not experiment with it? For everyday headacheless needs however the answer is no; Dalvik is just more refined and you should stick to it.
[Nexus 4 General] underskyzx:
Pretty much, the 2 tap swipe to zoom on chrome started to freeze for over 2sec constantly
[Nexus 4 General] utsmaster18:
My experience with ART has been great. All my apps work and everything is lag free, though even on dalvik it was pretty much lag free, ART seems to just clean up some of the rough edges.
[Nexus 4 General] UK-Sense:
I agree with the above, all my apps work, even Chrome so for the time being ART will be left running.
[Nexus 4 General] Parvinder25:
I have been using ART since past one week without any issues. In fact, for me the battery backup is better than dalvik. The only issue was with whatsapp and it got fixed by the solution provided in one of the threads. Titanium Backup resolved the issue with ART with their latest update... so all good so far. It feels smoother than dalvik. I am gonna stick with ART.
[Nexus 4 General] moon-unit:
I find that WiFi takes a few seconds longer to lock on and sometimes uploading to Google+ from the gallery bugs out. Might go back to Davlik, I think Art needs more refinement and maturity before it's ready for a daily.
[Nexus 4 General] sss_ddk:
Great

Switched to ART. No problem so far. The phone just flies.

Among apps that i use (and that are working with ART): Firefox beta,Android Firewall, Deer Hunter, ES file Explorer, Horaires Me, Avelib,Light Flow,VidTrim,Opera Beta, MX Player, Music Folder Player.
[Nexus 4 General] cincibluer6:
Just updated titanium backup and supposedly has ART support now. Anyone on Art care to try it? I'm still running dalvik.
[Nexus 4 General] PatrickMac:
Yes, works flawlessly for me
[Nexus 4 General] Impo5sible:
I'm using it for a couple of days and it's fine.

Also, I have been using ART for 2 weeks maybe, and haven't got a single freeze, or crash with system/app.

I don't know if this is KitKat related or ART related, but since I started using KitKat+ART my Swype keyboard has been draining my battery consistently. Has anyone experienced such a thing as well? One can clearly see I've disabled Swype the last half hour or so :)
[Nexus 4 General] BoneXDA:
Typical wakelock issue, Wakelock Detector or whatever compatible with ART should tell you what service is keeping the app from deep sleep. I had Swype acting weird but turning off all access in AppOps helped. Notifications are disabled too. If issue remains, a reinstall may help, but it could be an ART issue.
[Nexus 4 General] cincibluer6:
I had the same issue with Swype on Dalvik but it seems to have gone away. Not sure if it was somehow related to the kernels I've been trying out or just did it on its own but it now consumes like it did before.
[Nexus 4 General] Runatal:
I have an issue with Ruzzle, the app stops running when I'm looking for an opponent. I think it is ART related but I am not sure.
[Nexus 4 General] arenola:
For my own, art feels faster than dalvick and it is more battery friendly..
[Nexus 4 General] adichandra:
For me, art is not about opening apps a bit faster, but the most important thing is scrolling performance on browser or apps like tapatalk. Feels like an iphone's speed.
[Nexus 4 General] Irwenzhao:
If it's true that it feels like an iPhone's speed, after Google finishes developing ART and most apps are compatible with it, it'll attract more users from the iPhone user base.

My conclusion is art feels faster than dalvick
[Nexus 4 General] xboxfanj:
It's not Motorola specific. It's Qualcomm specific. Any Qualcomm device that isn't a nexus uses qc-opt and libqc-dalvik (included in dalvik), but the moto x one was used because it was the first 4.4 stock ROM out. When the HTC one or S4 or G2 official ROMs come out, they will also have Qualcomm's optimizations. They may be slightly different and you can compare by adding the files.
[Nexus 4 General] rajendra82:
I was on the optimized Dalvik on 4.4, but had to reflash stock system in order to update to 4.4.1, and decided to give ART a try again. Dayum it make a huge difference. I had never tried it for long before for the fear of app incompatibility, but it seems to be smoothed out now. Facebook upload working, TiBu has been updated. I don't think I am going to go back to Dalvik (optimized or not).
[Nexus 4 General] chiewable:
Switched to art after the 4.4.1 update mainly (because of whatsapp compatibility) .

Alot smoother then Davilk

[Nexus 4 General] M@rs:
Anyone compared dalvik and Art side by side in 4.4.1?

After switching to art I notice faster app loading speed and the scrolling in apps is much better.

I'm on 4.4.1 and all apps work fine except pulse. Seems like the layout of the app either isn't compatible with art or 4.4.1.

Also notice better battery life on art.

Google f***ed up mako with the KitKat... N4 with art feels like n4 with jelly bean (smooth, like it should be), and with dalvik it lags (in multitasking, most noticeably). It's like Google did this on purpose (to make n5 feels a lot more smoother). Dalvik and bionic patches help a little.

I think it's a 4.4.1 issue and not an art issue. Mine doesn't work either. I'm waiting for an update from mx player

[Nexus 4 General] BoneXDA:
Can switching between ART and Davlik (with some apps installing/updating on one, others on the other) cause issues?

I just wanna try ART out for a few days on 4.4.2, switch a couple of times for speed comparison, and if unsatisfied, return to Davlik, but only if this doesn't cause issues of any kind.

Does it?
[Nexus 4 General] Bloodykiller86:
I had dalvik enabled earlier today on slimkat 4.2.2 and the laginess of everything from apps opening up to the multitasking was horrible. Turned on art and ive never seen my phone work so fast. There's no lag anymore. Apps open instantly, ui doesn't lag at all. So far Google adding this new runtime seems to be a great move :)
[Nexus 4 General] jcmaddox1:
Well, KitKat, on my Nexus, with a bit of ART, I have to say it now runs smoother than iOS. Its perfect ;) now my friends can't tell me I have micro stutters because I just don't since I enabled art.

---------- Post added at 12:10 PM ---------- Previous post was at 12:07 PM ----------

It shouldn't - the system will just keep re-optimizing itself for dalvik or ART every time you change runtimes. I kept switching and didn't have any issues for the first day of 4.4 testing it.
[Nexus 4 General] BoneXDA:
Thanks. Good I had some juice on the battery as I didn't expect it optimizing ALL apps upon restart. It indeed feels very fluid, did not encounter any issues in the first 30 minutes. Definitely snappier by just a noticeable bit.
[Nexus 4 General] shadehh:
It is crazy. After flashing roms and they typically start up in dalvik mode I am kind of amazed because the difference is very noticeable now. Art reacts noticeably faster after having used it for some time. Can't imagine my phone without it anymore.
[Nexus 4 General] jcmaddox1:
If you try turning off ART you may have the same problem I did, which was "****. I have to keep art enabled. I'm too spoiled by the smoothness"
[Nexus 4 General] vukaleksic:
don't update Quora app because it keeps FC on ART :(
[Nexus 4 General] PGvossman:
I just activated it and I can feel a huge difference. I was expecting not to really notice anything but the app drawer is unbelievably snappy and opening a recent app is as fast as the speed of light. Wow.

Did anyone else's phone get very hot during the change though? I put it down and after coming back to it after it had finished about 5 minutes later, it was pretty hot. It's cooled off now but my phone has never been really hot (surprisingly).

[Nexus 4 General] Bloodykiller86:
Yeah it's a side effect lol once you use art you can never use dalvik again. It's almost like going from ics to jellybean lol
[Nexus 4 General] Fatherboard:
Switched to ART. So far, so good. The device is just a tad snappier (especially when trying the app drawer). Nothing too shabby.
[Nexus 4 General] arpitnathany:
Till now my assessment of art is this.

Its better than dalvik but not perfect.

Some apps open faster others open a little slower on the whole it balances out.

The most major improvement for me has been in scrolling the random microstutters have been reduced but not completely gone scrolling in poor apps like tapatalk and Engadget are a lot better almost smooth.

App switching and multitasking in general is faster.

So in conclusion art has a lot of potential but its not completely there Google is doing a lot of work but the app developers also need to do some work and then we'll truly have the perfect art experience.
[Nexus 4 General] sid.8491:
ohh...my bad.
[Nexus 4 General] s30ckf:
Same here, during conversion is pretty hot, and now it cool back.
[Nexus 4 General] tye_time:
I'm not seeing any battery life improvements using ART; I read somewhere that it was meant to by about 20%

The main things I noticed were much faster multi tasking switching and also the scrolling lag in Chrome is 90% gone. Any reason why ART can't be enabled on the nexus 7?

[MENTION=362591]tye[/MENTION] time, Art only works with devices that sport a snapdragon processor. That is one of the down sides. But if that's what it takes to optimize a droid then so be it. I'm sure snapdragon will be featured in many android devices just like it is now. :). That also would mean that nexus devices will probably come with snapdragon processors which IMHO I cannot complain about. The s400 is still very very fast considering it is among the CPUs that can be considered dated.
[Nexus 4 General] tye_time:
Absolutely, Nexus 4 is still so fast! That's why I didn't upgrade to the 5, just didn't see the need to - I don't think I'd get any other device that didn't have a snapdragon processor.

To be fair even without ART my 1st gen nexus 7 is really fast, probably helps that I've got nova launcher installed though :D

I don't know if this is related to ART but since I switched to ART, it looks like my battery drainage turned inconsistent. There are too many times in which I notice that the battery looses 2-5% at once and it drives me nuts. I'm running full stock, unrooted.

Whats the diference etwen ART and Dalvik ?

Nobody says the details of both(dont know how to call them). I only know Dalvik, the virtual machine from the recovery. I'm using CM11 NIHGTLY 4.4.2 with Dalvik and the battery life its a lot better than 4.3 JB. So if someone could explain what ART and Dalvik do on kitkat Ive be much appreciated.

[Nexus 4 General] nowster:
(Sigh) Don't bother doing that, it's pointless.

The battery stats file(s) are only to provide the pretty graphs you see when you use "Settings -> Battery". They're nothing to do with the real percentage values, which are internal to the battery controller and only reset when you do a near full discharge and recharge.

Using my n4 since 1 year now. I always used cm. Since I switched to Art a week ago I can say I get definitely better SOT (5-6, sometimes even more!! hours/on dalvik just 3-4). I just have 2g enabled and chat through Whatsapp and Sms, some wifi browsing, not more. Performance may be better, but I cannot really say, because dalvik is very fast as well. All my apps work, so I don't see a reason to switch back to Dalvik. :)
[Nexus 4 General] PGvossman:
I don't know about everyone else, but it seemed like my battery life was a lot worse. I didn't run many apps and hardly did as much as I did with Dalvik yet the battery always went down fast. I'm switching back, hopefully I don't notice the phone being slower.
[Nexus 4 General] shakeador:
In my case I cannot change Runtime from Dalvik to ART, when I chose to change it, it asks me to reboot the nexus, but after this it remains in Dalvik, I do not know if this has something to do with the modifications that I have made to my Nexus:

- I have rooted it.

- I have changed kernel to Franco.

- I have installed Xposed Framework and Gravitybox module

Am I the ony one that cannot change to ART?

With that said both devices seem very responsive. I will know more when I have more time on it.

I swear it is like having new stuff ever since the 4.4.4 update. My battery has been great and I'm finding no bugs at all. I was really considering upgrading to a nex5 but this thing still screams! If art makes it even faster then I will hold onto it until the nexus 6!
