Try a software update and you will get a modified status alert and unable to update your phone. Going back to Davlik solves this fortunately.
[Galaxy S 5 General] Stiflerlv:
I went in local shops today to check out new S5.

I went in first shop, it had 2 display galaxy S5. Both were version SM-G900X (Yes X)

I didnt find enable ART option in deleoper section.

Went to 2nd shop, they didnt have any display ones, only real ones for sale. It was SM-G900F.

It had ART option in developer section, did turn it on, reboot (motherr ****er 300 apps on that phone) and it worked nicely. Didnt notice any improvement between dalvik one.
[Galaxy S 5 General] simacca:
Isn't it supposed to free up more ram and enhance battery life?
[Galaxy S 5 General] brazcub:
I just got my GS5. I love it. Don't know if I'll be enabling ART just yet though
[Galaxy S 5 General] natefish:
I think the only way it might free up memory is the way it caches apps differently, but I could be wrong. Of course, that might help battery life to if something is already cached. So, I hope you are right.
[Galaxy S 5 General] skeamznz:
Art does indeed save battery and make a smoother experience I've been running it on my S4 with aosp roms
[Galaxy S 5 General] smeet.somaiya:
I think different variants will have different compatibility.But it shouldn't be like this.

As far as my knowledge goes TW framework doesn't support ART.

And those who are enabling ART should go back to developer options after the phone reboots in ART mode and see if the selected runtime is still dalvik or is it changed to ART.
[Galaxy S 5 General] Stiflerlv:
It was still at ART after reboot on display device.
[Galaxy S 5 General] B1aze:
Yep, got it on my G900T here since day one and I'm rooted. Haven't enabled it yet though.

[Galaxy S 5 General] brazcub:
That's good to know but the question that remains unanswered is how does ART impact the GS5?

I won't enable that on mine until I know it's worth losing my warranty for it.
[Galaxy S 5 General] Apoxx:
I run ART and it's smooth and flawless. It feels noticeably faster too.

It won't let me check for new firmware anylonger though, says the device has been tampered with. Can probably just switch back to Dalvik whenever an update comes around.
[Galaxy S 5 General] kirdroid:
That's interesting.. So are you sure switching back to dalvik removes the tampered flag?
[Galaxy S 5 General] WizeGuyDezignz:
Yes, it does.
[Galaxy S 5 General] skivnit:
Yes running art sets the status to custom then going back to dalvik resets it to normal
[Galaxy S 5 General] simacca:
Yes indeedy [emoji4]
[Galaxy S 5 General] Darth Ziggurat:
How do I enable ART? I cant find it in the settings, I have enabled the hidden developer options.
[Galaxy S 5 General] xaznxplaya:
Select runtime system
[Galaxy S 5 General] Smoothcrm7:
So I have also been using ART since my device arrived Thursday.

Yes it seems to make white screens less apparent and apps seem to load faster.

If you decide you do not like ART you can disable it reboot your device and it will return to Samsung secured rather than custom.

Just a tip
[Galaxy S 5 General] crazymook:
I definitely noticed a difference switching to it. Everything is much snappier...have yet to experience any battery benefit tho. But I just switched yesterday so Im sure it takes a charging cycle for things to settle down.
[Galaxy S 5 General] simacca:
Gonna wait for more users input on art before I decide to try it again.
[Galaxy S 5 General] AngeredNumber:
Anyone experience this.... I have been running ART, switched back to Dalvik to check for update, which all went fine. now trying to go back to ART and it will no go back just stays on Dalvik? Also my system status is back to custom. I am rooted and have Philz recovery but everything else is stock. Can anyone tell me why i cant go back to ART now? Cheers :good:
[Galaxy S 5 General] simacca:
Wouldn't your status say custom because you are rooted?
[Galaxy S 5 General] AngeredNumber:
Yes but when i came back to dalvik it went back to official. The thing thats bugging me is i cant get back to ART now.
[Galaxy S 5 General] crazymook:
I switched back. Was starting to run into unexplained issues today (like my screen refusing to turn back on) and had no answers. Switched back just now...hoping that solves everything.
[Galaxy S 5 General] Darth Ziggurat:
I was afraid I had to reinstall the apps that I wanted to use ART with, but thankfully while booting into ART it says

Android is upgrading...

[Galaxy S 5 General] gyxter:
It was awesome at first, then I experienced this after my gallery crashed while selecting images in studio for photo collage. Switched back to dalvik for now.
[Galaxy S 5 General] Danh2009:
I switched my ART on the day I got the phone (last saturday 12/4/2014), now I'm wondering if I should switch it off. Isnt ART the "way forward"?

I have had no problems at all, by the end of the day I have been ending up with around 50% battery.

Im going to switch ART off today and see how it goes for the rest of the week.
[Galaxy S 5 General] degast:
As long as it's in beta, it's a way sideways.
[Galaxy S 5 General] gyxter:
While you're on ART, try going to gallery then options > studio. Then make a photo collage.
[Galaxy S 5 General] Danh2009:
I was expecting a big crash and a force close error.

Instead i got a photo collage!

What was it meant to do?
[Galaxy S 5 General] skivnit:
He thought ur phone would crash like his did
[Galaxy S 5 General] gyxter:
I reactivated ART and everything went fine again. I haven't tried other samsung apps yet but so far studio is working again.
[Galaxy S 5 General] TechNut*:
I've been on ART for over a day and am moderately using the phone....

I have not had any issues and was able to put together a collage via studio without an issue...apps and phone are super snappy and am not getting any errors when looking for a sys update... there are none so that could be why...

Hope this helps..
[Galaxy S 5 General] Danh2009:
Must have been a temporary glitch!

Ill post if i find anything that may be broken.
[Galaxy S 5 General] double002:
I used ART for 3 days but I had two problems, :

- several black screens when unlocking the phone. I had to try several times to succeed

- 2 reboots, for no reasons, and actually the phone was blocked on the Samsung boot logo

I just switched back to Dalvik to see if ART is really the source of the problems or not!
[Galaxy S 5 General] Danh2009:
It wouldnt be a phone model version problem would it?

Im not sure of the differences between the 900F's and other models. Surely they should all roughly be the same. Maybe we should keep a log and see if a pattern emerges.

I have been running ART for 4-5 days and had no issues.

Still running stock rom on my 900F aswell (no root and Knox still intact)
[Galaxy S 5 General] Ave666:
I've got the same problem for the black screen thing on art. But now I had no such problem because I'm switch back to dalvik
[Galaxy S 5 General] double002:
Same here: SM-G900F, no root and Know warranty at 0x0 (checked it today)

I really think that ART is still unstable! Dalvik is working just fine, I think that the differences between ART and Dalvik are not perceivable for now
[Galaxy S 5 General] Br4nd3n:
Posted this in the AT&T thread so I'll forward it here to resolve these ART threads.

"You must realize that almost all apps are in Dalvik bytecode. Dalvik is a form of JIT compilation (Just in Time) which is not native but doesn't pre-compile anything; making it less memory extensive but causing longer load times. ART uses AOT compilation (Always on Time), which is faster for android because it's native, however it translates Dalvik into a system dependant binary (pre-compiling the entire app) which makes it load a lot faster but it also slightly more memory extensive.

Older devices with less memory benefited from Dalvik, while ART is more practical in today's use since our phones have so much memory.

AndroidPolice had awesome benchmarks for Android 4.4, I attached an image of their benchmarks. You'll notice CPU had a huge benefit in ART but memory did not, and was slightly worse.

ART is still experimental and may have problems translating and pre-compiling some apps, which is why you will experience crashes and bugs; though some will function fine. Samsung has even said ART is to be used with caution on their TouchWiz due to all the applications being Dalvik bytecode."
[Galaxy S 5 General] Danh2009:
Thanks Br4nd3n, Think ill turn Dalvik back on for now. Seeing as there id no real reason to have it on, especially seeing as the S5 has enough memory and cpu.

The only reason i turned it on was because i "wanted" to.
[Galaxy S 5 General] AngeredNumber:
Some please help me, i still cant get my device to boot into ART even after changing from Stock to Alliance rom. :( I dont know what the issue is. Any help would be great thanks.
[Galaxy S 5 General] ChadH42:
WOW... ART has caused my reboots after clearing cache from 2 minutes to 25 minutes!!
[Galaxy S 5 General] Br4nd3n:
Are you selecting it in developers options?
[Galaxy S 5 General] AngeredNumber:
Lol yeah mate. I select it then it asks to reboot. So i do, but never optimises the apks.
[Galaxy S 5 General] gyxter:
Im really having good battery life with ART enabled. Standby time is much better than in dalvik. I've not experienced any reboot after 2 days but having some google process fc which happened only once and it hasnt affected anything. So I say ART is much better than dalvik.
[Galaxy S 5 General] Ave666:
Did you encounter black screen lock issue?
[Galaxy S 5 General] gyxter:
Once on my first activation of ART. Then I switched back to dalvik then back to ART and since then no more black screen.
[Galaxy S 5 General] odd29:
Im using the alliance rom and art is not activated after reboot.

Is there a workaround?
[Galaxy S 5 General] kms108:
I'm with the 900F, and i cannot find the developer option, can anyone direct me.

thanks
[Galaxy S 5 General] gyxter:
Go to about then tap build number 5 times to enable dev mode. Did you try googling how to enable it? ;)

By the way just a warning when ART is enabled some features will not be working like screen mirroring and private mode. This is because it triggers phone status as custom.
[Galaxy S 5 General] kms108:
thanks, if I want to remove the develper option, how do I do this.

thanks
[Galaxy S 5 General] gyxter:
I think that's irreversible
[Galaxy S 5 General] kms108:
did a bit of search, not actually tried it, it's either factory reset, fota or clear the setting option.

not sure which one will work or not.

thanks
[Galaxy S 5 General] delawaredrew:
I've been seeing this occasionally on Dalvik so I was hoping ART would help. Enabling now, 316 apps upgrading! After years on custom ROMs I'd forgotten all the crap that stock has. I haven't seen more than 125 or so apps for a long time.
[Galaxy S 5 General] gsfesz:
Whwn i enbaled ART on my sprint s5 i pulled it out of my pocket and it was really hot and stuck on the Sprint logo
[Galaxy S 5 General] justinsch03:
wouldn't do it

I just tried it on my Sprint S5 and it speed things up a lot, but then it wouldn't allow me to install anything from the play store, the connections optimizer started crashing even though it was off, and then the phone would just freeze. Had to take battery out, and immediately shift back to dalvik. Now running fine but phone lags when multiple apps were open (ie family guy and Facebook in background)
[Galaxy S 5 General] AdamLC:
I sometimes get that. I found that holding down the power button turns the screen back on :laugh:
[Galaxy S 5 General] Airboner:
i dont have any issue with studio with art enable it..

i mean i dont have any issue on my phone..

maybe your variaty has to be ;)

on sm-g900H everything is ok:good:
[Galaxy S 5 General] Valdeck:
Aside from very large apps you wouldnt notice a difference with ART for speed but it will help your battery though how much is hard to tell until you use it.
[Galaxy S 5 General] ozonenetwork:
It seems that private mode unusable on ART enabled.
[Galaxy S 5 General] rodnah:
I found out s note doesnt work when on ART, I also had stuck on black screen at time to time. Reverted back to dalvik and quite stable now.
[Galaxy S 5 General] Sincci:
It seems to be working just fine for me, but I did experience one black screen quite soon after converting to ART. This happened week ago and I haven't been able to reproduce it since.
[Galaxy S 5 General] ddaflorez:
have switched to ART a couple of days before and didnt notice any app fc but sammobile , i guess it happens because y dont have the lattest update for this app. Will update and report back .

[Galaxy S 5 General] DRSdroid:
This is exactly what happens on my T-Mobile GS5. ART option is there, can enable it.. system reboots and when you go back into dev settings the runtime is still dalvik
[Galaxy S 5 General] ashraf sharif:
Privacy mode does not work in art, stock not rooted sm-g900t
[Galaxy S 5 General] arghness:
As noted earlier in the thread, setting ART sets the phone security status to "modified". I believe that privacy mode doesn't work with the modified status flag set, as rooting the phone has similar side effects.
[Galaxy S 5 General] Avera6:
With the new update you on longer get the modified status it says official but you still have privacy mode issues
[Galaxy S 5 General] Morinzo:
I have found 2 games that doesn't work in ART mode but everything else seems to work fine.

I had to turn ART off on my wifes SM-G900R6 because her fav game Bubble Blaze would not load.
[Galaxy S 5 General] dandroid13:
Why do you people want to use FART? We all know it's experimental and can cause issues.

Enviado do meu Galaxy S5
[Galaxy S 5 General] John822:
I didn't like it, made my phone laggy
[Galaxy S 5 General] sofia-captivate:
what is art and what exactly it does? android run time?
[Galaxy S 5 General] GibMcFragger:
Yes. It replaces Dalvik cache. It's still experimental, so it breaks a few apps as well as runs slower.
[Galaxy S 5 General] Slicktune:
well its about to become the industry standard on the next version of android...sooo umm... we gotsta get used to it...plus its suoer duper blazing faster....!
[Galaxy S 5 General] drakester09:
Breaks a few apps, yes, although compatibility has greatly increased.

Slower, no. At least on Nexus devices it's a sensible improvement.

I haven't really tried it on the S5 for more than a day, I really like using xposed.
[Galaxy S 5 General] GibMcFragger:
I ran it for a day, and although I had no issues with apps, they took considerably longer to open. It was noticeably slower, at least in my testing. :)
[Galaxy S 5 General] ogremount:
The apps that worked worked a bit faster, but more than half of the apps either crashed or didn't open at all. All official apps from market.

Will be waiting for future development.
[Galaxy S 5 General] :
mine stays at custom after changing it back to dalvik...
[Galaxy S 5 General] threedfx:
I found both of my S5 devices (SM-G900F and SM-G900A) to launch the apps slower in ART than Dalvik. :confused: Went back to Dalvik and running fast now. Not something you would notice right away unless you have two devices to compare and do your own side-by-side with.
[Galaxy S 5 General] bmwjnky:
My S5 is doing fine on ART, no app issues and was able to do an update through Kies just fine yesterday. I have the SM-G900T for T-Mobile, all stock un-rooted. I might go the rest of the week on ART and switch it back to Dalvik over the weekend to see if I notice any difference.
[Galaxy S 5 General] jgalvez21:
i cannot enable it in my exynos s5

disable xposed. delete greenfify

when it restart it doesnt do galaxy optimization

my take is , it doesnt work with root?
[Galaxy S 5 General] drakester09:
You need to uninstall xposed.

It should work on G900H, it does for me.
[Galaxy S 5 General] gee2012:
I think Dalvikstill is faster and more stable atm on the S5 than ART, maybe because Samsung hasn`t fully optimised TW yet. ART is definately quiker on the Nexus 5 though.
[Galaxy S 5 General] MateusMaciel:
Problems with ART

I don't know if this is the right thread to ask but here I go:

So an hour ago I decided to try ART on my S5 (international Qualcomm variant/not rooted) and now i'm having problems with it. It took about 15 minutes to optimize 400+ applications and now everything stopped working. The first thing I noticed was that the TouchWiz launcher was crashing over and over again. Then I decided to open the settings via the notification bar on the lock screen so I could switch back to Dalvik, but it also didn't work. The application crashes every time I try to open it. So I rebooted the phone and it was still optimizing about 40 applications and nothing was working. The only thing that works is the lock screen, some report-bug app and the notification bar. And the phone is alerting me that the storage space is running out.

Can someone please help me? I'm desperate.
[Galaxy S 5 General] bmwjnky:
This. Switched back to Dalvik they other day on my S5 and the first thing I noticed was when my aux connector is plugged in it would recognize it almost instanly. When I was running ART it would take about 5-10 seconds before it would recognize the aux connector. Battery life looks to be better as well back an Dalvik, got about 30 hours before the low battery warning on my last charge with using the phone a lot. Other than that I haven't noticed too many other changes, some apps looked to open a touch faster on ART but without a second S5 to test with side by side its hard to say. It will be interesting to see what Samsung does with Android L as L is completely dropping Dalvik and only using ART.

You can try getting to the menu to do a factory reset, otherwise you can try to reset it back to stock with Kies.

DALVIK>>ART switch

My SG5 heated up when I switched it to ART, anyone had the same behavior? Themer Crashes on the regular and a few apps do it as well. Any thoughs?

[Galaxy S 5 General] amirsarv:
I switched to ART some time ago and the device is running much faster and smoother, programs open way faster! But I have huge battery drain! Android System is draining battery even more than the display, Anyone encountered such problem?

[Galaxy S 5 General] leonreijnders:
I had the same thing on ART, wen the phone reboots all went fine but after a minute of so it freeze up and reboots and stuk at the Samsung logo.

To solve it i removed mij sd and sim card, go quickly to developer option to switch back to dalvik
[Galaxy S 5 General] Juno-First:
Just become the proud owner of a Samsung Galaxy S5 SM900F the other day so its all stock & not rooted yet.

After updating the firmware naturally I ran Antutu & got 35015, bearing in mind I have 359 apps installed :eek: .

After enabling ART an old app called cpu-temp monitor widget FC'd but thats the only mong so far.

Just ran Antutu & got 34415 :confused: .

Anyway, I'll give it a test over the next few days see how it compares to the past couple days.
[Galaxy S 5 General] Nour826:
When I first enabled ART, SWIFTKEY app crashed. I uninstalled it then reinstalled it back to my phone then it is working normally. May this mean that we need to do this to whatever crashed app after enabling ART then no problem
[Galaxy S 5 General] Nour826:
Has anyone managed to root S5 while on ART runtime mode, or changed to ART mode while already rooted? I am interested to know if any problems between rooting and ART runtime mode.
[Galaxy S 5 General] Moosetracks:
Since rooting, I can't switch to ART. My phone reboots and I check the runtime and its dalvik again.
[Galaxy S 5 General] Nour826:
Well something confusing here because I have already rooted my device today then I could change it to ART normally.
[Galaxy S 5 General] Moosetracks:
What did you root with? I had yo use towelroot as I'm on att. Maybe that could be it?
[Galaxy S 5 General] Nour826:
Rooted using CF-Root
[Galaxy S 5 General] curioct:
Hmm reading the moving to art doubled really interesting but losing exposed really doesn't sound worth the trade off
[Galaxy S 5 General] scainbestone:
I am rooted using Towelroot, 4.4.2, G900A, and have switched to ART after the first week of ownership.

I noticed greatly improved battery life and faster reboots.

The only real issues i have are that all rooted programs do not work in ART. If i want to freeze an app (App Quarantine or Titanium Pro) i have to switch to Dalvik, do what needs to be done, and switch back.

The apps themselves open, but none of the freezing takes hold.
[Galaxy S 5 General] Nour826:
Noticed the same for TB. But System App Remover application does work & removes any unwanted applications. Which is pointing a problem with TB itself & its compatibility with ART. for me as long as I still have alternative app, I will c9ntinue using ART.
[Galaxy S 5 General] v_square:
Just for info. S Health still doesn't work with ART even after the ANG3 update.

Sent from my SM-G900H
[Galaxy S 5 General] Nour826:
S Health is working for me after the update & i am running ART

Switch to ART, then back to Davilk, system storage was 10.1 and now 9.6... ?
[Galaxy S 5 General] zeusumit:
I have been using ART mode since 2 weeks now and I am now getting amazing battery life.:good:

As far as smoothness with the operation is concerned, I have not experienced any noticeable difference.
[Galaxy S 5 General] aguarello:
For me, the deal breaker is the lost of private mode with ART...

I've tried it and is amazing, the battery life is wonderful and it's a little more snappy.

If anyone knows how to make the Private Mode work with ART, please let us know :)
[Galaxy S 5 General] Michael_P:
For some reason when I switch to ART after it reboots I check and still shows it's running Dalvik.
[Galaxy S 5 General] aguarello:
Maybe you're running Xposed framework, which breakers art...
[Galaxy S 5 General] Michael_P:
No it's not installed and I'm just running rooted official.
[Galaxy S 5 General] speedme:
Really ? I am running ART on my rooted S5 since the day I got it (2 weeks ago) and I have Xposed framework running....

I also have amazing battery life and very snappy UI
[Galaxy S 5 General] IzZYJr:
Does ART really improve the battery life?
[Galaxy S 5 General] eRPeeX:
Afaik Xposed cannot run on Art.
[Galaxy S 5 General] Tron666:
Please stop trolling. Youre not 10 years old. Xposed cant run art.
[Galaxy S 5 General] speedme:
Sorry, I misread this screen :

I thought it ment that I have ART running (so not selected) and I could switch back to Dalvik.

My bad...
