hi i previously had a sony xperia s and when i rooted it and everytime i powered it on i used to say android is upgrading and would scan through my apps and this also happens to my mums galaxy s2. so i wanted to know that when rooting the nexus 4 does that happen as well and if it does how do you remove it.
thanks
It sounds like your dalvik cache was being wiped at boot and thus had to be rebuilt every time. Were you using V6 supercharger?

No, it shouldn't. Rooted mine a few days ago and I believe the updating thing only happened on the first reboot. Haven't seen it since. It will show up each time you flash a new ROM and then after installing a new app and rebooting. At least my Galaxy Exhibit always did.
android is upgrading is your dalvik getting rebuilt. you either have a mod that is doing this or you are using a root app that has wiping the dalvik as a feature thats enabled. since it happens on your sony too, im willing to bet its the same app that you are using on both devices.
Simms is right (when isn't he ). There is probably a root app building your dalvik cache on reboot. It's been happening to me too. I Googled a little and found out TiBU was causing it. I uninstalled it and reinstalled and everything is fine now.
Thanks

what difference will it make if I change the runtime from dalvik to ART in developer settings in KitKat 4.4.2 ROM? Will it make my phone faster?!

Presuming ART on your device works...IME ART is much more snappy than Dalvik.

While changing the runtime to ART it gives this warning, should I continue? what r the risks?

The risks are it's experimental technology that you're given a preview of because you enabled developer settings. Also, some apps may not work. And please don't file bug reports on the ROM or apps because you're using experimental settings. Honestly, I'd leave it on dalvik if you don't know what you're doing.
The risk is that you may brick your ROM and need to do a Nan droid restore to get it back.
I think I'll leave it as it is for now, don't want to risk bricking my device ?

Stop giving false information!!! There's no case where using ART has bricked one's ROM (if that's even possible!).

There's no risk bricking your device by enabling ART. Sure some apps might not work properly, but the majority will work ok. You can always try ART, see what you think and if you don't like the results, you can revert back to Dalvik. Keep in mind that if you have Xposed framework installed and you try to change your runtime to ART, you might end up with a bootloop. So make sure you have a backup, just in case.
But, I repeat, it isn't possible to brick your device by changing to ART.

Lordy. Are you kidding me?
Of course it is possible...AAMOF, for most KitKat ROMs on the Sprint SPH-L900 enabling ART WILL render your ROM unbootable and the only "fix" (that I know of) is a Nandroid restore. AFAIK the only ROM for L900 with working ART that I know of is OmniROM, although I will admit I haven't tried straight CyanogenMod in forever. "Working" meaning enabling ART doesn't break your ROM. Because what will happen otherwise is after enabling ART and immediately rebooting, your ROM install will permanently bootloop, and the only way of getting it back is Nandroid recovery.
Don't believe me? Download or read the XDA forums for Dirty Unicorns 5.0 or SlimKat (no offense intended at Maz or sleshy who do mad work on those ROMs and who are more than aware of this issue). Then you'll see exactly what I'm talking about and that it is you who are "spreading false information". Further even within the same ROM, enabling ART can break the ROM for some devices but not others. If you read or follow Google+ dev communities for OmniROM and others you'd know this.
"False information" indeed.

bootloop ≠ brick
Two very different situations. You used the word brick, which does nothing but panick whoever reads it, because it insinuates bad things. On the other hand, a bootloop is a much more manageable situation.
Could anyone tell me, if the device is bricked or struck on bootloop will I still be able to go to recovery mode?

If your device is on a bootloop, you will be able to go to recovery mode. In case of a brick, in most cases you won't be able to turn the phone, let alone booting to recovery mode. But enabling ART has nothing to do with bricking the phone.

This is Xposed Framework: http://forum.xda-developers.com/showthread.php?t=1574401
You'll know if you've installed it, by checking if there's an app called Xposed Installer.
I'm running art out of curiosity. everything is working fine, no problems at all. but honestly, I cant tell any difference between art & dalvik in terms of speed/battery life/whatever. the only noticeable difference is the longer boot time with art. I do not keep track of ram usage or do any speed tests or details like that. Maybe there's a difference on that level, but it's not perceptible as a user, imho.
so, at this time, is it worth switching over? eh, not really. doesnt matter much.
Yeah even I switched to ART but didn't notice any changes except that all the apps take much space than dalvik n I also noticed my battery was draining sooner so switched back to dalvik, it's better for now until the ART is fully developed on our device

For me, art don't think that makes so much difference. It's experimental and we have to wait for next major android release.

How do i know if I'm really using art? I've checked it and let it boot. Now when I go in the settings it says "using dalvik".

Yes,so i think I'm on dalvik? Xposed shouldn't work when on art.

Xposed automatically kicks you out of art runtime whenever you try to get into it. so your options are:
1.keep xposed active and forget about art until the developer works on compatibility (which should be soon)
2.or deactivate (or uninstall) xposed and use art runtime.
You should weigh the pros and cons and see which is best. btw no bricks will happen if you choose to use art.
Hello fellow N4 users,
I noticed few threads about ART actually running quite well on our device and I thought I'd give it a go aswell. However when I go into Dev settings and select ART instead of Dalvik, my phone just simply reboots and nothing is changed, the option is set to Dalvik again. I'm rooted on stock ROM. Any ideas?
Thanks in advance.
The same happen to my phone on rooted rom. On my S5 art works fine, I don't know why it won't enable on N4.

So there's completely nothing to do atm except waiting for 5.0?
I've notice this used to happen when I had xposed framework installed (xposed is not compatible with ART).
Do you have Xposed installed?
I feel like a real noob... You're right art is not compatible with Xposed... Thanks for pointing it out.
Hi, im having some lag problems with my N4 after the lollipop update... Specially with the new messenger app and swipping left to google now... I wiped everything (data, cache...) and the problem still there... So i just want to know if you guys are having the same issue or if its just my phone and have any idea to fix it...
I installed lollipop with the factory image not OTA... Maybe thats the problem, i dont know... Thank you and sorry about my english xD

Messenger is slightly laggy but not too much. Dont keep clearing recents (in case you do), that messes up the android cache mechanism and apps take longer to launch.
Dear Community,
I'm using SPenCommand v.1.2.36 on my Note 3 SM-N9005 with CM13 and xposed.
It used to work flawlessly but it started (without updating ROM nor App) to tell me touchscreen device and SPen device were not found.
Wiping cache and Dalvik/ART does solve the problem for a few hours but it keeps coming back.
Any suggestions why it does stop working?
Best regards
Un install spencommand and reboot and install again
