Just a quick question, i rooted my z2 the other night, mainly to remove a few system apps..... facebook you gotta go lol
Anyway i was wondering, with the new changes in kitkat, i dont remember full details but there was something about uninstalling apps also uninstalling associated folders files etc to do with said app, how does this affect system apps, are there now useless inbuilt apps that were previously safe to remove that now maybe arent coz they share a folder with an important app or anything like that i should be aware of before i start removing things, maybe thats why 'disable' option was added?
sorry for spelling/grammer, im tired n cant be bothered t check things
Hmm im not sure what your asking but
Disabling apps doesent remove their data
Removing apps via root deletes the app not the data, the OS should remove the data
Could you specify your question or problem?

In the end yeah a list would be cool..... but what i mean is: say you install a picture editor, edit a couple of pics then delete app. On earlier versions of android only the app would be removed, and apparently on kitkat it will remove app, edited pics, any folders app created etc....
I was just wondering if any system apps share folders or resources or whatever, thereby possibly altering functionality/performance of one app when i uninstall a different one.
I had a picture editor and i edited a pic, deleted the app and the pic was still there
I have never heard of this before and i dont think its a easily possible to implement in android

I think if you use Titanium Backup to delete apps it removes all the apps related files too. Except user created files.

This should only happen if the app stores the edited pics in its own private folder.
If it uses the common public Pictures folder that won't happen.

yeah, i know i just used pics as an example, i remember reading about it when i was looking to get a new phone, something about the system cleaning itself up after uninstalling, so you're not left with all the useless pics (on my galaxy note, a couple of emulators created a folder in my gallery for all the on screen buttons n stuff, which i had to delete 1 by 1 after uninstalling the apps) n folders n backgroud processes n whatnot.
Back when i first rooted my note, i referred to a list of things safe to remove, some of these were like background processes or something but if i remember correctly, a few of them were used by more than one application, so if was wondering if system/root apps behave the same as user installed ones when uninstalled on kitkat with the cleaning up, and if they do maybe something that would have previously been safe to remove, now isnt because it would clean up (delete) something that was also being used by a different app
In the last few days, somewhere in the xperia Z2 section I saw a thread with a list of system apps/bloatware that are safe to remove or freeze. But I can't find it now.

Hi,
what does it mean technically if an app is "freezed"? Is the APK moved to another location, or are the unix access rights altered, or is a reference to the app deleted from some kind of "registry" of the Android system, or what else? Can it be done manually by a file manager?
Thanks,
Stefan
It can be done using the purchased version of Titanium Backup and probably a few other apps. It basically renders the app inactive without uninstalling it. Helpful for bloatware that runs in the background but you can't decide if you want to delete it or not.
Thanks, but this was not my question...

Most freezing apps simply rename the app to be frozen with an extension, like in the case of Bloat Freezer (IMHO the best one) the frozen app gets a .bzw extension. It remains in place but of course cannot be executed. The nice part is that if you run into an issue you can just rename the app back to what it was (assuming that you have root).
It works!

Cool, so simple - thanks! So it can be done with any file manager.
I've just successfully frozen the preinstalled "LGWorld.apk" by renaming it to "LGWorld.apk.bak". As soon as I had done this, a message popped up, saying "Deinstalled", and the icon disappeared from the app drawer, and also the update for "LG World" vanished from the Market app.
Hmm.. freezing doesn't mean rename. It is being remove from system. If.you rename yourself, the apps may failed to work.

Freezing the app works via decreasing the temperature of the app to roughly 50 Kelvin. At this point the the app's molecular structure becomes a super condensed crystal lattice. Due to the nature of the crystal lattice, android treats the super dense app as non existent. Essentially the app is deleted from your system completely. However, think of it not as a permanent deletion but rather a reversible one. Should you chose to 'restore' the app, you can defrost the app. You could defrost the app using a microwave but I for one use TB Pro as it does a far better job.

Manufacturers and carriers often load Android phones with their own apps. If you don’t use them, they just clutter your system and sometimes in the background, draining resources. Take control of your device and stop the bloatware.
We’ll be focusing on disabling – also known as “freezing” bloatware here. It’s a safer process than uninstalling the bloatware completely, and is also easier to accomplish with free apps.
Uninstalling vs. Freezing
Uninstalling an app is exactly what it sounds like – the app is entirely removed from your device. Unfortunately, it’s not possible to get many of these preinstalled apps from the Play Store if you ever need them again. Uninstalling some preinstalled apps may result in problems or instability, so you could run into problems.
It’s safer to “freeze” apps instead of uninstalling them. A frozen app is disabled completely – it won’t appear in your app drawer and it won’t automatically start in the background. A frozen app cannot run in any way until you “unfreeze” it. Freezing and unfreezing are instant processes, so it’s easy to undo your changes if you end up freezing a necessary app.
If you really must uninstall apps, you should freeze them first and wait a few days to ensure that your phone or tablet works properly without them.
You can’t uninstall or freeze preinstalled bloatware apps without root access and third-party app managers. Try and you’ll find the options grayed out in the standard Android interface.

I understand and have frozen quite a few apps with TB Pro. My issue is there are shine pre-installed apps that I like to use, but when I run the task killer, they're always running. Is there a way I can fix them where they don't keep starting immediately after killing them, but still having them available when I want to use them?

Another app called greenify. Or using an autostart manager to prevent them from running without ykur intervention.

Thx a bunch. I dwld and installed the grenify app and disabled them, however, when I run my task killer the gallery app is always running. I wanted to greenify it, but it's not showing up in the greenify app, even when I did a search for it, it just took me to my home screen. I clicked on the app and it just opened but I didn't see any options to greenify it. Any suggestions? Thx for ur help.
so at the end is freezing and renaming the same thing? no one cleared that up, i usually just rename to BAK and thats it, what does TItanium apart from renaming?
ok i answer myself, freezing is the same as going to app manager, and selecting DISABLE
or from a root terminal using:
pm disable {package_name} (e.g. # pm disable com.android.browser)
wich calls:
/system/bin/pm
wich in turn contains:
# Script to start "pm" on the device, which has a very rudimentary
# shell.
#
base=/system
export CLASSPATH=$base/framework/pm.jar
exec app_process $base/bin com.android.commands.pm.Pm "[email protected]"
what it does is set a flag for a component to some of different values:
COMPONENT_ENABLED_STATE_DEFAULT
COMPONENT_ENABLED_STATE_DISABLED
among others. (http://developer.android.com/reference/android/content/pm/PackageManager.html)
where does it store this flag: I DONT KNOW
is this flag a value inside some manifest/ini file? : IDK
is this flag st in the file system? IDK
can someone show me the light?
edit: I DONT KNOW for sure but i think it stores it in : /data/system/packages.xml
that is generated by package manager taking info fro each app manifest. i hope i am right, but dont take my word as absolute truth since it was a quick google research lol
Renaming the apk file can result in unwanted behaviour... I learned by trial&error! I'm running MIUI 6 and wanted Google Play as default app store and not the MI Market. Renaming the apk file for the Mi Market gave me the result I wanted: launching Google Play whenever I clicked a link to a certain app. But that was until I rebooted the phone... it got stuck on the MI startup logo. After renaming the Mi Market apk file in twrp recovery, my phone booted again.
So might try freezing it to see if it will do the job properly.
Freezing Mi Market with AppFreezer worked like a charm!

Depends what you mean by "renaming." Changing the extension from .apk to .apkold or .bak or something like that will harmlessly freeze the app since it's no longer seen as an apk by the system. Renaming the app itself is another thing entirely.
I renamed the extension to .noapk and Miui wouldn't boot anymore.
Good stuff
Ok, I'd like to remove apps that I don't use (stock browser, for example), so if its possible, has anyone figured out what apps can be removed without affecting system performance?

I removed a whole bunch of apps using Titanium Backup and Root Explorer last night. I really wasnt keeping track, I just removed the obvious ones..then I did a google search and it redirected me back to a thread in this site that actually lists what each app does. try to find it, im not sure where it is.
I think this is the thread you're referring to
forum.xda-developers.com/showthread.php?t=1681729
I've been going through Titanium Backup and freezing some of the apps.
Hi Everyone,
Like the title is suggesting, is there a list of critical apk files that android needs to run?
For example, whenever I install a ROM I always find myself deleting most of the standard apps or other **** I just don't use with a system app removal tool.
Now I just want to delete everything, just to have a naked android system and from there on, install apps I DO need.
Thanks in advance,

No, there's no actual "list". You'll just have to use your best judgement in removing (i.e - do not delete all of them). You could use this app which can advise you which apps are safe to remove. If the app doesn't show up in the app drawer, its quite likely you should not remove it (& possibly vice versa).
Well it needs SystemUI and framework-res in order to boot.You also need some launcher and most provider apps if you want to use ur phone. But as was said above if an app doesn't show in drawer you shouldn't delete it

Really depends on what rom. Certain stock ones have different dependencies that may cause FCs if removed. Depends also on whether it is Touchwiz, motoblur, sense, or others

Hi all,
What I want to do: remove all Timescape elements from stock Sony ROM safely (avoiding force closes, not random deletion)
Why: I noticed that a Sony executive announced a week or two ago that their 2013 phones will not have Timescape running through the phone because it did result in performance lag. Instead they will use one app for the same purpose. I want to test removing the lag in my phone by removing anything Timescape.
News on Timescape: http://www.xperiablog.net/2013/01/14/rip-timescape-long-live-socialife/
You need a rooted device and an explorer with root access like ES Explorer in order to delete the apk files in the System/App directory. You can find more information at the bottom of the first post in this thread: http://forum.xda-developers.com/showthread.php?t=1546253&highlight=bloatware.
I would recommend not to delete them actually just in case you want something back. In my case I have only change the file extension so the app won't start. For example gmail.apk has been renamed to gmail.apk1
A few months ago I clicked 'allow Facebook to sync with contacts' and similar options, I thought some features were useful. I tried disabling them all today and it has already made a helpful boost in performance. The true test will be a few days performance.
What I did was root my phone. Then I used an app manager that would allow me to disable system apps. That way I could easily restore any app that are really required. Anything with time scape or Facebook got disabled. I also disabled all system apps that were available from the app store.

No need to root. Just goto the app manager and disable all timescape items and anything else not needed.
I rooted and used Titanium Backup where I uninstalled all "Timescape"-related (appr. 5-6 entries...)
Root needed to delete

You still need root to delete system apps. Once you have disabled them and decided that causes no issues, deleting them will free up a little space.
A few days ago I disabled as much Timescape as I could and so far it really does remove a lot of lag. The phone is already usable...
It can be nice seeing friend's Facebooks pictures etc. in your phonebook but the lag is not worth it. :victory:
My GT-S5830i is increasingly getting slower and slower.
Andriod: 2.3.6
Kernal Ver: 2.6.35.7
Build: Gingerbread xxmd1
Various apps running 195MB used - 32MB Free
The 3 major app memory usage, Facebook @33MB, Weather Channel @16MB, Android Antivirus @24MB
The rest as far as I know are standard Android system apps, the only duplicate app I can see are 2 Google maps each @5MB. I have tried un-installing one or other, but they restart themselves.
Any tips of improving access speeds to various common apps, such as txts and phone contacts etc to dial. Also photo's which are all stored on a SD card as are all videos, sounds and etc.
thanks

See don't use Facebook app it slows down our phone go for another one
And delete those system app's which you don't use for more detail (how to )follow these Guide
By doing these it will free up some Memory .
thanks,
visited the link and looked at all apps on my phone to compare..
i have uninstalled the Facebook app and added a shortcut instead. For all the green apk's to be deleted, although listed and most are not used. Cannot delete any, only clear data or force stop. Yet when looking down the app list, some have restarted such as 'maps' and 'email'.
thanks again

Do as @Envy-X told
First Root your Ace and then Delete those unwanted system apps by any Root Browser
It will delete that app permanently.
