Has anyone tried switching to ART yet? Have you noticed any problems or benefits such as increased fluidity or battery life?
I switched. No problems except every time I reboot it always optimizes 44 apps. I don't know what that's about.

Yea, did that on Nexus 5 Android L Preview as well. Probably a small bug that needs working with.
That's the main problem you'll encounter. And other small things like some apps not working correctly (like Pandora).
I switched to ART, and my Pandora is working.
It sure takes a long time to reboot as it optimizes 66 apps. Switching back to dalvik.
I've noticed an extreme lag on my note 4 when I switch to ART. Not only does it optimize apps whenever I reboot, I've noticed the length of time to do things such as freeze apps in Titanium backup takes longer. Apps such as S-health/Spotify/facebook also take a long time to load versus Devik.
It might be my anecdotal experiences, but I've noticed the same thing with my G3.
I've switched back to DEVIK until another ROM comes along.
after going back and forth with art/dalvik, on a couple of different phones, I think its a combination of certain apps on our phones not being compatible, and the fact this is a modified form of ART, made to work with version of android below 5.0
even though I dont have this phone yet, I think its probably fast enough with dalvik, to not bother with ART until Android L comes out..
WTF, the whole idea of ART was to compile applications during install and be done with it, as opposed to Just In Time, when you compile right before application start, each and every time, so you guys should have delay using Dalvik, during reboot all apps are started and should be recompiled, not with ART which should be precompiled already, what am I missing here? You're describing just the opposite of what it should be.

Yes, and yet, that is what is happening. ? Crazy
Art sucks on the note 4. As everyone said it takes forever to boot up as it tries to optimize several app at ever reboot. In my case 29 apps and it'd slow like molasses. Once booted, some apps also take forever to load like Facebook. Art is more a disadvantage in the note 4s case. Went back to dalvik.

day 1 went with dalvik. no issues while setting up the phone how i like it and using it. switched to art yesterday afternoon and switched back to dalvik lat last night because i had major hangups in apps(timely alarm took 5 seconds to open, freezing with dolphin browser and words with friends. that i can remember) hangups were so bad it even locked up the phone a few times where capacitive buttons would not work for multiple seconds. dalvik is doing just fine, not enough benefit for me to go back
It's pretty much a waste of time to use ART at this point in time until L is released. If there are any benefits right now, it's either very very minimal or placebo. Wait until it is official with L.
I switch to ART now and i never encountered your problems... after that it reboots then optimized 349 apps on my device then it boots. after that it became laggy i tried playing need for speed for the first time it freezes i close the app and waited for a period of time and try again after that theres no lag at all even the TW launcher. i have no problem with my apps i swear. ill try to make a video tomorrow.

Is it just me or does it take an EXTREMELY long time to boot the first time after you switch to ART? Ive been stuck on "Optimizing app 246 of 386" for like 10+ mins now.
Im starting to think this was a mistake...I restarted and now its stuck on "10 of 190"
Big mistake. It will do that on every reboot and your phone will get really hot. Nothing you can do now but to wait it out. Go back to dalvik asap.

You have to just let it finish. It takes a long time but should not have any bad side effects. ART loads a bigger portion of the applications you have installed on your phone into the cache. That is why it runs faster, because it is holding more of the applications in a preloaded state. This is also why the boot takes so long. You should also see a bit higher RAM usage when the phone is idle.
But this allows the phone to have more stable operation and improves efficiency which is why you generally see a better battery life and less cpu waste.

My phone basically got stuck booting i had to completely wipe in recovery to get it back up. Maybe I just had too many apps installed? Like my phone literally was booting for half a day...LITERALLY.
when I switched to ART, S Health stopped working. Had to switch back.
Absolutely no issues running ART for me. I checked everything I can think of and all appears to be good.
Pardon my ignorance, but if I already run FireKat V5 on my N4, what benefits or is it even possible to switch over to ART runtime?
I'm using ART on my S3 and Nexus 7 for about some months now. All in one it's a very good user experience to me using it together with CM nightlys.
Now I've tried enabling it on my new and rooted Note 4 at the usual way. Well. I get the question to switch and reboot, but the boot time is at usual and the runtime is always Dalvik. So if I try to switch back to Dalvik there is no prompt for reboot because I'm still on Dalvik instead on ART. Whyever.. no ART runtime for me on my Note 4 running KK 4.4.4.
Well, except all the (as system app installed!) bloatware, I'm still feeling happy with my new device.. even without ART.
Btw: Anyone knows a good list of those installed system apps I can securely remove without using special apps like SmartDebloater?
Thanks in advance and regards.

Anyone have been using ART on Note 4 can share what is your experience?
Personally I don't find any noticeable improvements. However, the extra time it takes to complete app updates and installations is pretty noticeable. Not that much of an issue on that, but there is one little annoyance for me - whenever I reboot my phone the same set of apps needs to be optimized and the reboot process takes over a minute for that.
I hope this is just because it is still kind of a "test" feature on 4.4 though.

Same. I have about 15 apps that it will keep optimising (I guess it is the decompiling) every time it is rebooted. Currently returned back to Dalvik.

I read someone's contacts app was broken as well, but mine seems fine. Didn't test out private mode though cos I don't use that function.
Doesn't work. No improvement whatsoever. Don't bother at all. Lollipop will use it properly
Echo the above posts. Annoying that it kept optimising apps on reboot, takes up extra storage space and actually seemed to appear to stutter more.
Anyone running ART? What's your experience?
I'd hold off for now. After switching to ART, I started having random phone shutdowns. The screen and side buttons would become unresponsive, then the screen would fade to black like normal, but could not wake it back up. Only way to get it back was to hold all 3 buttons down for 10 seconds to force a reset... and then sometimes the same thing would happen again immediately upon reboot. For some reason it's buggy on some devices and works well on others (I'm obviously one of the unlucky ones). ART will be the new default when we get Lollipop, so hopefully the bugs will be worked out by then.
Ya I was having a few small bugs with ART as well. I switched back to dalvik and those bugs went away. I'd stick to dalvik for now until 5.0 comes out...
It's a curious thing that various people are having a different experience when switching to ART. I switched to it recently out of curiosity and haven't noticed a difference. It's just as smooth and stable as before.

How about battery life?
i think it's about the same. I haven't been paying close attention, but I think if there were a noticeable difference than I'd see it.
With my usage (avg ~ 2hrs screen on time) I'm at around 60 percent battery by the time I get home from work.

I switched to art directly when I started the phone the first time. After 2 weeks I switched back to dalvik and noticed a major difference.. For me, art is much smoother, more responsive, snappier, everything is faster.
I switched back to art and everything was fine again. Never had problems with art.
When using dalvik after only using art, the phone felt like a fast car but with art it felt like the same fast car and now someone finally uses the last gear and steps more on the gas.
Just my experience.

No because our optimized Dalvik is still faster than ART and it supports xposed
On the OGX I ran ART but just got this Pure edition and I will stay Dalvik because we will be on the new android version soon. No reason to change for me right now.

Hey all.
I tried switching the runtime to ART and lost all use of the power button. So I'm back to Dalvik again. Is anyone else having this problem and if so, have you found a way to fix it
Thanks!
I've been on ART since Monday and have had no issues
Until you do a reboot, then it recompiles the run time all over again. I've also been being some random FC's on phone and ui but other than that it's fine
I switched over to ART and it is optimizing 60 apps after every reboot ? going back to Dalvik for now also battery life for me has been somewhat shorter..

I was getting rather crappy battery life after restoring apps via helium phone was awake 100% of the time, I switched to ART and now the phone sleeps. As a result battery life has improved!
I've been running with ART since I got it on release day and haven't had a single app fail. Maybe I don't have a lot of apps or something, but so far, it's running great.
Anyone been running ART?
I enjoyed performance on my HTC M7, but the battery life seemed shorter. Could have been other factors, but am curious as to what people are doing on Turbo.
I don't have any performance lag, so I don't imagine this things running any better than it is. Especially at the sacrifice of battery life.
I've roamed google and can't find an answer. I tried to switch to ART...3 HOURS ago! It keeps getting stuck! I read some forums and rebooted, it'd say "upgrading x out of y apps" but the Y is always different (up and down) and the X it gets stuck on is always different! at first I assumed because I have a podcast app that has over 1.7 GB of data, but going on 4 hours?
Worse, the recovery partition isn't showing up to wipe dalvik cache or data- it just says NO COMMAND, and does not respond with any menus. Tried the factory reset, and tried even using adb to wipe. Nothing is anything other than stock here. nothing is responding. It just keeps going back to the "Android is upgrading" Any ideas?

I've noticed ART doesn't seem to play very well on mine either. Upgrading apps everytime you reboot. Boot sounds play when on vibrate/silent. There's quite a few quirks but those stood out the most to me. When lollipop is official, we won't have to worry about that nonsense. For me, I'll have this phone about 10 more days before I send it back to Verizon.
Issues with ART aswell... Several apps optimize after every reboot.

After waiting about 6 hours, and even trying to wipe cache and everything, eventually I had to wipe data and do a factory reset, and got ridiculed on the private forum for the soak on even tryingART (oddly). So for the moment, I'd say we wait on LP b4 using it consistently.
I ran ART for about a week or two. The optimizations grew on every reboot. Switched back to Dalvik and my battery life improved.
Stop rebooting then . Art runs great. Better battery and snappier with window animation s turned off. If u have problems its either your phone or operator error

Naive comment. If there is a phone problem, you likely will need to reboot. Operator error doesnt cause a phone to reboot either.

Why buggy and broken? Besides the optimization on boot, for which we don't know whether it's a bug or has its reasons, art runs great on the turbo.
I can't say much about GUI performance, the GUI is blindingly fast on dalvik, hard to say whether it's blindinglier faster on art or not, but it's definitely not slower.
Battery life on the other hand makes a huge jump with art! Especially system uses way less power, in my case less than a third. And that's definitely worth it!
There might be issues with some applications from the play store (which is most likely a compatibility topic as with any major android update and not one of bugs) , so far I didn't run into any, though, and I've got plenty of apps installed and in use - none of them exhibit the slightest issue at all.
All this said, if you don't run into any trouble with any of your key applications, I definitely and highly recommend art!

Interesting. Did you figure out where the power went to? Did you compare fairly, as you had the phone new, usage pattern and installed apps might have undergone a fair change.
As a side note, I only tried it with the latest update, maybe that makes a difference as well...

I switched to ART maybe a week after I got the phone, so I was through the new phone setup. I was on that day 1 update (.15 or whatever) when I was trying it. I wasn't scientific about the testing at all, but I did use it for two weeks so I think it was a pretty comprehensive representation of my usage patterns. After switching back to dalvik, my standby time in particular jumped noticeably. Different strokes for different folks? I don't know, but personally I will be sticking to dalvik while on Kit Kat.

Apparently, pity. Looks like it ain't a sure win, thus. Guess, as you said, one has to try it out and see whether it works out for your particular combo of apps and usage...
Thanks for shedding light on that dark side of art.
I'm on the maxx, didn't get much out of art for better or worse. I didn't notice any performance difference nor change in battery. I did find the rebuilding annoying though since I reboot at least once a day after I update my hosts file and I'm trying various other changes in exposed and so on that require a reboot.
I just made the switch to ART and I can say for sure it's snappier. I am going to see if the battery life is any better tomorrow but so far I am impressed. I have the Verizon version of the Note 4 in white. Specifically the open windows button on the left side of the home button is way faster. It takes about 15 minutes to reboot the first time you do it and the battery will feel really hot during that time but it's back to normal now. Keyboard feeling way faster too.
I switched a few weeks ago, and while it was faster, there were still some apps that were buggy (WhatsApp was really buggy if I remember correctly). N910T
I have not used many apps so far but will report back any issues I find for sure.
I did this yesterday, the phone was a bit buggy, I then disabled S health and everything became snappier. There is still some stutter (stock so far) here and there, but animations seem to be improved. Battery life has been a bit worse so far.
I tried ART the week I got the phone, the boot up when switching had the phone crazy hot, but after while it cooled down, I found the phone was a tad snappier, but not big enough of a step for me to stay with ART, moved back to Dalvik 2hours later when some 3rd party apps force closed, will wait for Lollipop rather, lol.

Me too, being Android you kind of have to restart the phone regularly and to have to wait for the apps to update + overheating and losing 5-10% battery each time, just not worth the hassle...
I just went back to dalvik with fresh install and I definitely feel it lags more lol
I can't switch to ART cause im on a rooted W* with TWRP but i can tell you, by experience, and with the Note 4 again, always flash stock firmware through odin and factory reset after and the lag will go away. I don't why but every time i get a new Samsung phone, it lags, but when i flash stock and factory reset after that, it's MUCH better

Hello,
I've updated my Nexus 7 first-gen recently to Android 5.0 and since than have spent a good amount of time using it. I use the tablet for work and fun through out my whole day, so snappiness is a big factor for me. With the 4.4 update, the tablet just got a lot slower, sometimes I needed to wait for a few seconds before I am able to kill a task. Clearing cache didn't fix the issue.
Made me think about that 5.0 update a lot. (Note that I actively started using the tablet only a few months ago. I had it for 2 years but broke the screen 3 weeks after buying it and only now I decided to repair it.)
The 5.0 update it self took a good 45 minutes. When I loaded it up for the first time, man it was buggy, I couldn't complete a single task without it bugging out. All of the Apps and settings were there untouched. The first thing I did, was go into recovery mode and cleared the cache. Then I cleared the cache for every individual app. And that boosted the performance by 100%. Next, the animations, I cut them down to 0.5x and turned on GPU rendering (just for testing) turns out that helped out a lot. I didn't notice a difference in load times, like some articles suggested.
However there are a few quirks, the sound lags behind the slider, so if I crank up the volume to MAX it will take a moment to do so. I often found my self having to tap the apps drawer button more than once to open it. And the killing of tasks is not as easy as before, now you have to slide from one side to the other in order to kill a task you can't just kick it to the side. Also, the auto-brightness is really aggressive so I disabled that. The WiFi status, when you click on a WiFi connection seems to be broken since in portrait mode all the letters are separated, and at first I couldn't make out any of it. And the biggest downer for me is the keyboard, I think they didn't do any favors with it. I have larger thumbs and it will take some time getting used to the keyboard. These are all small things, but they affect my experience.
Now the good stuff, where do I begin? The interface, it's great I like the design and the contrasts. Performance, I guess that's the biggest question since this is not exactly cutting edge hardware. To summarize it, it's good. I haven't had any issues since I cleared the cache, apps are running as they should, games as well, multitasking is as expected, fluid. Later on I switched the animations to 1.5x and 2.5x. no issues there. Boot up times, something completely irrelevant to me, but since there are people that would like to know, it takes around 30-40 seconds to boot up. However, Chrome is still the biggest enemy. If you want something to make your tablet miserable and make you wait and get frustrated because of it's unresponsiveness, you won't need to search far, just get Chrome.
All in all, the update was a step up, and an improvement.
These were my 2 cents on the subject. Hope it was of use to someone.
thanks for the review. I also updated a few days ago when the ota came through. So far, I'm experiencing terrible lag. I don't have anything stored on the N7 and don't have many apps. There is a ton of available storage on my 32gb. I did a factory rest about 3 months ago, as I like to every now and then to give the N7 a fresh start. I think I may have to yet again and keep my fingers crossed. Unfortunately, it's unusable at this point.
My experience has been variable, but not unexpected. In the past I have had issues with installing OTAs resulting in poor performance -- sluggish response to touch, certain apps immediately displayed odd lag, etc. Going from 4.4.4 to 5.0 was no different. So, I performed a factory reset and the effects were stark. The performance is exactly where you would expect it to be for Lollipop i.e. it is smooth.
HOWEVER, all is not well. There seems to be a set of problems that I suspect is related to Lollipop utilizing the ART runtime. Certain apps, even before performing a factory reset, were really really slow when running the first time. I have experienced this before: when I tried out ART when it became available on the Galaxy Nexus. Two common apps this occurs with are Facebook and Mint. Who's to blame? The app developers? Google? Don't know but hopefully these issues get resolved soon.

Ugh, that is quite an issue. Have you tried wiping the cache? You should check your usage, you might be able to find out what's hogging your system, unless it's the OS it self.

I also tried out the ART on some devices, mine were not even supported. There were a lot crashes but I also noticed some performance improvements.
Does factory reset also wipe the cache?
My Lollipop experience with my 16 GB WiFi-only Grouper isn't as good as yours. First, I thought I messed something up by rooting it with NRT, but after a manual factory image (flash-all.bat failed out of the box) without root it didn't get any better.
Most time its not as responsive as my N5, I've already had 1-2 minute hangs followed by hung apps (Google Search/GNL, system in most cases) and heavy lagging under most conditions. From time to time its getting close to 75-80% of the smoothness experienced on the N5 (which has better hardware, of course).
I have no idea what went wrong, I've already enabled 2D GPU hardware acceleration, but I'll definitely wipe the cache in recovery once more - you never know...
Thanks for the extensive review - Chrome is just a pain in the a** if you don't have at least 2 GB memory available.

One thing I forgot to mention is that after the cache wipe the tablet was fairly fast but I also went into Settings > Storage, and noticed I have a lot of app data which frankly shouldn't be that much. I then went and cleared cache manually on every app and as it turns out, I managed to scrape off another 1GB there. So, I'm not sure how that would affect the overhaul system performance but it sure helped me get the snappiness I have right now.
Looks like wiping the cache had an impact on performance. I wasn't able to play around much, but it definitely felt faster after first reboot.
Too bad I just noticed my user partion only had 6,x GB (8 GB image obviously) - there are so many ways you could f**k up an Android system - so I'll have to format user data once more, approximately the third or fourth time in the last week.
Sometimes I understand why people fancy those awful Apple devices, but let's hope the speed boost persists.
Go in and delete all the apps in system folder that can be installed from play store and are not needed. After installing the lollipop images you have 11mb in system which seems to be main cause of lag. I freed up like 160 mb and no lag or stuttering. Not sure why google kept things like dialer and other things unusable on the tablet in there.
Also get now launcher and delete launcher.
For even better performance get faux kernel (Set kernel up to his recommendations) and/or install aosp 5.0 F2FS with minimal 5.0 gapps.
Oh I do have a problem with WiFi being weaker on 5.0 though.

i am getting terrible lag too. last week i updated with the OTA file. wiping the cache improved performance but only for a short time. i guess eventually if ii want the speed back on my 2012 nexus 7 i am going to have to root and go back to jellybean

Go in and delete all the apps in system folder that can be installed from play store and are not needed. After installing the lollipop images you have 11mb in system which seems to be main cause of lag. I freed up like 160 mb and no lag or stuttering. Not sure why google kept things like dialer and other things unusable on the tablet in there.
Also get now launcher and delete launcher.

Thanks, that sped up things significantly. It's definitely a memory problem, because event on full stock setup you're getting glances of Lollipop smoothness.
But WTH is Google delivering a potentially lagging factory image? Couldn't they just resize /system by default in order to fit in all apps nicely? Well, that's Android - if it doesn't work, you have tons of options to fix it.
After my old N7 screen broke, I got a new refurbished 16GB unit for about US$100.
Had some bootloader issue earlier while trying to flash lollipop, and had to revert back to 4.2.2. Then it got all the OTA up to lollipop, and is running really well since.
Loving it now, better than most non-lollipop newer tablets around...
Lollipop is big disappointment. I hate new notification (double swipe down to access settings)
I am back on 4.4.4 Slimkat rom with Legokernel and f2fs
now is system smooth without lags
Listening to some of the advice in this thread, I rebooted into Recovery and wiped cache (I did it 3 times, because why not, right?)
In addition, I went into the developer settings and turned OFF "Force GPU".
After doing both of those, my performance seems to have greatly improved (specifically Chrome, which was borderline unusable).
For reference, I flashed the factory image from 4.4.4, and didn't get it OTA.

Sometimes I understand why people fancy those awful Apple devices, but let's hope the speed boost persists.

Not any more! I have three new iOS devices and things are far, far worse since iOS 8 dropped. Apple now holds the lag crown. At least with Android you can revert back to earlier versions that worked. With Apple all you can do is whimper at the master's feet.

UTTER nonsense. Stop it. System being full affects nothing; it's read-only.
Is there a way to disable the storage encryption that is enabled by default? Disabling this apparently had huge performance upgrade for the nexus 6

Swipe once with two fingers.
I've done cleaned every thing in this ROM, repeatedly. Hopefully CM 12 will make it work!

understand what you are saying but after doing so i have no lag.
Have 2 x 2012 and both were lagging. After trying other things i deleted stuff in system and both are very smooth now. Very happy with them.
Even wiped and re installed one and just deleted stuff in system, to make sure it wasn't something else or a combo of things i did prior.
