ART on Moto X

Anyone have any experience with this? Was thinking of switching to it, because it sounds like it could give a major performance boost to the phone, but am unsure because it is so new.
Anyone with major bugs because of switching to ART? Is it possible to revert back to dalvik once you switch to ART or are you locked in?

I experienced a visually slight performance boost.
WhatsApp won't work. Had a pain to get it working again after going back to Dalvik. Had to revert to 4.2.2, root, then update to 4.4 again. For that matter I'm not using it again until we get 4.4.2 which fix these issues.

If you ever switch to ART, you wont be able to use whatsapp even if you switch back to dalvik. You'll have to flash back to 4.2.2 and take the 4.4 OTA to get whatsapp to work again

I couldn't upload photos to FB every other version when ART was enabled. You can switch back and forth as often as you'd like, just prepare for a lengthy boot when switching to ART.
Waiting for 4.4.2 as other poster said. Currently running dalvik. I do think it runs better with ART. Snappier.

I don't think I'd use ART on the Moto X quite yet. Moto has apparently optimized the qualcomm dalvik libs quite a bit to give the moto x a smooth fluid UI. ART will probably be better for the moto x eventually but I'm guessing it's not optimized for a specific phone at the moment.

It's fast. I used to use dalvik for about a week than switched to art. I've used art for more than a month now. I have a lot of third party's apps installed, even nonmarket ones. My Moto x is on 4.4 and rooted. I've never experienced any issue since I'm on art. Don't use Whatsapp or games though.

I'm not saying it won't work, used ART on my N4 and S4 but I'm skeptical you are going to see better performance with ART vs. the highly optimized dalvik libs used by motorola for the moto x. Especially since it's unlikely google has optimized ART for specific hardware at this point.
In my experience with ART on the N4 and S4, some tasks seemed quicker, some seemed the same and some felt slower but I definitely took a hit in battery life. I'm guessing ART on the Moto X would have a similar reaction, some tasks might seem a little quicker but I'm betting battery life is going to take a hit as well as other tasks that rely on moto x specific hardware.
I could be wrong though since I've never used a moto x (just ordered mine about 12hrs ago so I'm waiting impatiently)

It's really hard to compare speed and other behavior between two runtimes if you don't have two equal phones and run both systems simultaneously. I never complained that Moto x wasn't fast when I used dalvik. It seems even more responsive now under art but it might be a subjective performance evaluation, you never know if you don't have comparable reference. Anyway I think that dalvik on android is more past than future and if you don't have a specific reason to use dalvik you should give art a shot.
Good like with your new Moto x. I believe you'll like it.:good:

I switched to ART a few weeks back, and at that time thought I noticed a slight improvement in overall performance. I was pleased. After about a week, I installed Xposed. Unbeknownst to me, Xposed automatically reset the phone to dalvik (xposed is not ART compatible). I did not notice the change for several days, until I happened to see the runtime setting on the developer options screen. To me, this is good evidence for a placebo effect.
But try it yourself. You can always go back.

Exactly! Optimized Dalvik on Moto X is as good as ART if not better.

There really is no benefit to art on the Moto x. It has hugely optimized davik libs. Now if Moto gives an update that has optimized art libs, it would be amazing. But for now, I am willing to bet that any performance increase is a placebo.

I only really saw a performance boost between ART and Dalvik when I was using recent apps. There was really only like a milisecond difference between the two, but it was enough to annoy me. Battery life is really good on ART, didn't notice enough of a difference between the two.

Having used ART on my Nexus5 and MotoX I can say that it is definitely faster and better battery life. Not just placebo but thorough testing and look at the battery threads on both forums for proof. I will say that the difference was greater on the Nexus5 than on the MotoX but I feel that Google designed the 5 with ART in mind. MotoX still has a good improvement and I have no reason to go back to dalvik.

I have been running art since it's release and love it. After numerous tests on two moto x's it is noticeably smoother. Much smoother. Battery life is a little better and certain apps open twice as fast While others do not open faster. I have 300 apps on my phone and since titanium added art support I have not found any app that does not work except xposed.

Just thought I'd give my opinion as well. I've used ART on both the Nexus 5 and Moto X, and so far from my usage, there's noticeable improvement in performance and battery life versus dalvik.

Alright I'll give it a shot tonight and report back on my findings as well.

I do not use whatsapp. i am a google voice / hangouts user.

Truth is, no one knows--it's anecdotal and small sample sizes at best. Use whichever placebo floats your boat.

After 2 weeks on ART, back to Dalvik. ART maybe faster (maybe placebo effect), but delivers lots of small irritations: calenders lost (solved only by reboot), evernote FC-ing (for the interested, when taking page picture), etc-etc.. All of them small by themself, but adding together: too many small problems to stay with ART.
Sorry to say, but IMHO ART is just not ready for showtime yet..

Lag Problems

Hello
got anyone these loag problems when using google Maps or when using some apps at the same time ?
my phone starts to be extrmly laggy.

a phone with 1GB RAM lags when multitasking heavily? wow, that's unexpected!

I know.

I am actually happy that unlike my old ****ty Samsung Galaxy Ace Plus, my brand new Moto G (2nd Gen) doesn't lag.

I've used GPS and PowerAmp (several times) with flawless performance, also running Next Laugher 3D, a power hungry launcher, with no problems..
Its all about what apps. one is running..some are more compatable with a particular device than others..

"Praise Jah" YOU people.!

My Moto G gets really laggy when charging and using snapchat at the same time. That's pretty much weird. :/

Only thing I have noticed is that when using certain apps and going back to the home screen...sometimes it takes a few (2-5) seconds for my home screen icons to show up. (Use Nova Launcher on every device)
I also have a 2013 moto g, a LG L9, and a cheap BLU phone...all with 1gig of RAM and none of them display this same issue.

My next
Moto G 2014 will be my next smartphone.
(coming from a fake mobilen (i8160 Galaxy Ace 2))

It's got some RAM managing problems I guess. I can't play Clash of Clans while listening to Spotify (music stops) for example.
Or the launcher refresh. I've got an htc one X with the same amount of RAM and that never happened to me. Wish they'll fix it, or that custom roms will.

This. I've got some weird issues as well that I never had with my S3, which also has a gig of RAM. Hope lollipop or any other future update fixes this issue!

You can try to change minfree values as you wish, for example:
Code:
echo "2048,3072,11520,16640,24320,42240" > /sys/module/lowmemorykiller/parameters/minfree
I'm quite happy with these values, more multitasking but still not so much lag

You could just give that command from the terminal emulator on your phone but once you reboot you'll lost the configuration.
I made a script for SManager ( you can find it for free on the play store ) in order to run the command at each boot, it's in the attachment.
To configure it open the app, select the script from your storage and toggle "Su" and "Boot" as in the screenshot below. Of course root permissions are needed.
PS: I also managed to enable init.d support in stock rom in order to avoid using another app, but that command is not run ( or something else restores the default configuration after it runs ). Don't know why

Ever since I changed my runtime to ART the hangup and lag have been becoming more of an issue to me. I own both the original and 2014 version of Moto G and I can say the former has a better hold on multitasking with the same exact apps that I have installed on my 2014 version. I'm still giving Motorola the benefit of the doubt though until they push the 5.0 update which I am hoping will bring better experience on the 2014 version.

Terrible Performance on ART?

Switched my Turbo over to ART thinking there was no reason not to on a device with this hardware. Turns out everything from the launcher to apps to boot are slower/laggy. Even swapping back and forth between homescreens has noticeable jitters. Anybody else attempted this or had different results?

I didnt notice a difference in perceivable performance. My antutu score went up though. Interestingly, runtime performance went down in ART, but multitasking went way up.

My score went from 44.3129 to 36.876, when I activated art.

Yeah, I switched mine and did notice this. So I switched back and am waiting till lollipop comes out to try it again.

The version of ART in kitkat is beta and was never intended for general use. It was there to help developers test their programs for when Lollipop came with it as default. Not surprising that it's buggy, still, on KK.

Lag

I've had the Moto X for about a month and a half and one thing that's always bothered me is the odd software lag. Let me point out where this is most noticeable:
- Twitter: with images enabled in the news feed, scrolling becomes extremely jittery. this issue is non-existent on the Galaxy S5 (I've tried them side by side and they have the same processor)
- Google Music: terrible experience all around when it comes to animations. when opening the app, the bar on the bottom that pops up with your last played track lags. when selecting your library the app lags when loading album artwork. everything about this app is laggy which is odd for the 801 + 320 chipset.
There are other areas where the phone stutters and I can't figure out why. It's been like this since day 1, and I don't have an excessive amount of apps running in the background (usually 850mb of RAM being used). Opening the app drawer and scrolling between home screens is smooth - it's just the graphics performance in apps can be utter crap. Anyone else notice this? I'm running 4.4.4 btw. I've been thinking of doing a software reset but don't want to go through the hassle. I don't have any out-of-the-ordinary apps installed so I'm baffled as to why an almost stock Android device behaves likes this.

This happens to me as well. For the hardware in the Moto X it sure doesn't perform like it. I actually made a post just like this the other day.
Are you rooted? I'm considering downgrading back to 4.4.4 I cannot stand it. I will probably end up returning the phone for a refund.

I'm honestly surprised to hear this, my moto X has been smoother than my nexus 5. I'd really try the master reset and load up apps a few at a time to see if/when you get lag again.

Something has got to be going on with your phone, the Moto X is hands down the smoothest Android phone I've ever owned which says a lot because I've owned upwards of 20, and most of them were flagships. I also have the N5 at the moment and the X is noticeably smoother when side by side, and that is a major feat considering how insanely smooth the N5 is. I'd do a reset and maybe even a reflash if you can. If that doesn't work, maybe you just got a bad device.

Me too especially chrome both on kitkat and lollipop and only on specific websites. Google books too to be honest but hardly noticeable.
I was surprised to see a bit of jitter considering the high praise it gets.
Now perhaps this is just how it should be, but the z3 compact with same specs felt faster albeit with a smaller res.

I've noticed it too. Can we find a common theme?
Mine is the pure edition with system version 22.21.11 lollipop
Build number LXE22.46-11

Just to follow up. I ended up unlocking the boot loader and rooting my phone, in the process essentially factory wiping it. Since then it's been noticibly faster.
I doubt it has anything to do with rooting it and everything to do with resetting it. I believe the OTA update to lollipop out of the box just left too much crap in the cache maybe? Who knows.
Now it's just like the nexus 5 in terms of fluidity

I noticed some terrible lag with the Telus 4.4.4 build. Even with a full reset it just never seemed to live up to the hardware standards. At absolutely everything my Nexus 7 2013 was faster(with both using the ART runtime).
One possibly significant thing I noticed with 4.4.4 is if I would ftp a file via wifi from a local machine the speed was incredibly slow, only 300kB/sec. Wifi however was super fast for nearly anything else, I also ran a flash benchmark test and it was quick. But when ftping and writing to flash it was always slow. I have since updated to the t-mobile lollipop build and the same ftp is now 2600kB/sec and the entire phone is quicker with no lag.

Lollipop runs like crap. Getting constant redraws all the time

That lower res makes all the difference in the world. It has the same SOC as all the current flagships, but because of the 720p display it'll outperform any of them. That's also one of the reasons why it gets such great battery life too. That phone is one seriously awesome piece of tech. And as much as I hate OEM skins, I actually like Sony's.

A lot of phones sometimes get lagged up after an OTA, even the iPhone can and has for ppm and myself. If clearing cache in recovery don't help try a factory reset. Its not a problem with just the moto x.

No lag here. This is the smoothest phone I have used non rooted.

Clearing cache did not have an effect, but a factory reset seems to have completely alleviated the lag/stuttering issues. Thanks!

Life with 1GB - How to live with 1GB RAM and hunger apps (Facebook)?

Hi guys,
I lived with low memory for a long time. Well, not ever. My first Android phone was a LG Optimus One, with Froyo/GB and 512MB. It was much memory (and useless, because the slow ARMv6 processor couldn't deal with it) compared the other low-end phones. The next phones, LG L3, Xperia Tipo, had the same memory size. Then I arrived to Moto G (falcon) times. Great specs (2013) to low-end devices. Revolution!
Three years ago we had JB and KK. Low system memory consumption. Facebook and Facebook Messenger was a single app. Whatsapp was lightweight. And 2GB phones was only for flagships.
Well, we come to today. Facebook alone eat more RAM than ever without Messenger. Whatsapp makes more and more things, and it occupies more memory. And Moto's LP and MM are heavy, much heavy. After some time trying to keep stock firmware, I wipped it and flashed XOSP, things are better, but not as desired.
Then, I ask you: how to live today with 1GB RAM? My Moto G 2014 "freezes" frequently. Multitasking is a dream. And Pokémon Go requires 2GB RAM devices (and crash sometimes because low RAM). Is there a hope? ZRAM? LMK? A lightweight custom ROM? Maybe an custom ROM compiled to optimize code size (using LTO?)?
Sorry by the sad mode. And terrifying english.

Hey,
i tested around with some custom roms, cause i had the same problems with the stock rom.
Finally i'm happy with this Turbo ROM ★ Layers ★ DUI [06/04/16][OFFICIAL] Custom Rom. I also flashed decipher as kernel. (not MPB) and installed greenify donate and l speed with the settings of amol amrit. Just deactivated the zram, cause Pokemon Go runs a bit better.
My G 2 feels like a new middleclass smartphone1!
Sorry bad english!
