[Q] How does a 'System' app behave? - General Questions and Answers

Hello,
I recently rooted my Android phone and so I was able to add system apps (-> move a normal apk to the system space).
The reason I did this, was because of an Anti Theft app, now it can't be removed (unless with titanium backup etc.)
My question is,
Will my anti-theft app survive a hard reset to manufacturers defaults now, and will it still have the correct data for me to trace my phone?
I am using a Huawei G700 + Cerberus Anti Theft
Thanks,
Jelle

Yes after hardreset your anti-theft will be there on your device as the app is converted into system app.

PreSS ThanKs If i HelPeD YoU ?!?

hii
Dude system apps are those which cant be accessed without root access. most of these are system apps, pre-installed apps, and your os.
they are not deleted by any means until you clear your system or sometimes flashing a new rom.
so dont worry while factory reset, you won't lose it.

Uninstalling preinstalled apps

Hello I've a Lava Iris 405 running Android 4.1.2 on a Mediatek processor. Likely you haven't heard the product name since its India specific. Still Id like to know how to remove preinstalled apps ? They gave me Facebook twitter rock stand and other crap. Together with three useless games they total up to around 80 MB of the 512 MB available on internal memory.
It'd be great if I could get rid of them permanently as I'm not sure I'll miss any of them or that any are integral to the system. I checked system<apps which listed the core apps but there was no trace of these crapware.
Help please. A non command line solution would be preferred since I'm a coding noob.

You may need to root your phone to remove preinstalled apps. If you goto manage apps and hit "all apps" you may be able to remove it there or at best, delete data and remove updates. If this is no use you will need to root your phone and use a third party app to remove an application. If you want to remove a game, that should be fine but if you want to remove an app you think you don't need but the risk is it maybe important to the operating system. in this case it would be better to freeze the app and see if your device works fine for a few days. If you can do everything as normal, the chances are it is safe to delete.
Be warned that some pre installed apps cannot be retrieved from app stores so if you decide you want it or them back, you would have to factory reset your device or reinstall whichever rom you removed it from.
Hope this helps... you should google or use the search here for answers as this type of question has been done a million times thus the solution has been fully answered too, many many times.
1.root
2.install costum recovery
3.take nandroid backup
4.install titanium backup
5.u can uninstall app from titanium backup and take backup in sd card also...

Thanks. I primarily want to get rid of Facebook Twitter Rockstand and three games (FlyBoy Private Sheep and Cricket fever). Don't think any of them are system critical.
My device is rooted using the scatter file method, with CWM and Root Explorer installed. Honestly I don't give a damn about warranty since the company isnt exactly Samsung or Nokia.

Its easy you have to be rooted.
Install system app uninstaller and uninstall the app which you want.

IS THIS HIDDEN IN ANDROID SYSTEM ? and Why ?

after trying Helium (the backup app)
ive noticed that every time i backup or restore
the screen flashes in another app which seems internal system app "built-in"
ive searched the settings and couldnt find it
ive attached 2 screeshots that shows this "Task"
if this is true
i think there is no need for any app to backup or restore
as this seems to be "built-in" thingy
what do u think friends ?
btw: my phone is Samsung S3 android 4.3
As you doubt there are built in backup system mostly. You should check for backup and restore in settings->backup and factory data reset.

after searching
i found it
its activated by some kind of code
but helium seems to do the same thing without the PC everytime
here is the link:
http://www.howtogeek.com/125375/how...kup-without-rooting-or-unlocking-your-device/
is there anyway to apply this code , or activate this task using only the android device ??

I have remove some system apps, but the installed after reset.

I've Rooted Gionee M2 8GB (KitKat). I have uninstalled some system apps . They uninstalled successfully as these apps are no more in the applications. But after i do a reset these are installed again.
I know its not a problem as I never face one. But I wanna remove those apps so that they don't come again with a reset. Is there any way to do this??
Use system app remover.apk
Hi, to permanently remove the apps, you need a system app remover, I have linked good one below, however, it does require root access.
https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp&hl=en
You have to remove it from thia directory...
Root/system/app/
By removing from here it will not come back by reseting..
Use root explorer for this action...

google prey or similar apps to be installed as system app

i would like to install google prey or similar apps as an system app, or default app so when you factory reset the device it is already installed with the user and configuration, are the tutorials "installing app as system app" the ones that will work?
any tips for where to go or what to do? thanks

If you're rooted you can use Titanium Backup to convert it to a system app or you can use ES File Explorer with root explorer enabled to manually push it to your /system/app folder then boot to recovery and wipe cache and Dalvik/Art cache then reboot to system.
You can also use adb to adb push it to /system/app folder.

It won't delete the app but it will delete the settings but you can also use Titanium Backup to backup and restore the app data for that app, you can also backup the app data to google and you can restore it from Google.

but will titanium backup survive factory reset?
do any one know if you can also move the settings to specific locations to avoid them being deleted? for airdroid, or google prey or any other app that can track?
for airdroid the apk and the lib files hat to be moved to system folders and it stays after a factory reset, but anything that looses the settings over a factory reset is pretty much useless for stolen devices, the first step a thief takes is factory reset and format the device. all aps on play store is as good as nothing when it comes to recovering a stolen device. :silly:

Titanium Backup will back up whatever apps, app data and settings that you want it to.
You can use Titanium Backup to make itself a system app, it won't get removed by the factory reset, then just use it to restore everything that you backed up.
There is plenty of information about all of this all over XDA and all over the internet if you'll just take the time to do some searching. Get off your butt and get to looking and you'll see.
As for the device being stolen, there are apps that you can install on the device that can be used to lock the device or wipe the device or even track the device to its location or last known location, whichever of those apps you use to secure your device can also be made into system apps using Titanium Backup. Then if its stolen and wiped the apps will still be there.
It isn't rocket science, why are you over thinking and complicating it?

hi, i'm not trying to over complicating it, the thing is that i tried moving aps like google prey and airdroid that can locate a device to the system folders but when i factory reset the device, the apps are there but the configuration of the aps is gone, i want the configuration to stay alive with the aps, because thieves just factory reset the device at the moment they steal it and then you kiss your device good bye, at least if i can get the configuration to stay alive then i have a 50% chance against thieves, at the moment the chance is next to none.
the reason i ask is to not waste time testing things that some one already know, i searched but don't find good tutorials on that, and i'm not sure if Titanium Backup will work for that, i was expecting some one knowing the software like Titanium Backup can tel me that if i do convert an app to a system app with Titanium, that the system app and its configuration will sirvive a reset and not just the app.
i will test Titanium Backup later today when i have some free time, thanks

Factory reset removes all data and settings when you factory reset even for system apps, there is no way to protect that data from a factory reset. You can back it up and restore it but you can't prevent it from being wiped.
There is an alternative though, you can remove the recovery, then turn USB debugging off then password/PIN protect your system settings app.
Removing recovery ensures that they can't use recovery to factory reset.
Turning off USB debugging ensures that they can't flash the device with PC or use adb/fastboot because PC won't recognise the device.
Password/PIN protecting your system settings app prevents them from getting into your system settings so they can't factory reset from settings.
The one issue with this setup is that if your device encounters an issue where it won't boot or bootloops then even YOU won't be able to fix it because you won't have recovery and you won't be able to connect to PC because you won't be able to get into settings to turn USB debugging back on to be able to flash it.
Research these things to verify its safe to do on your device because all devices are different and things are different depending on the device in question.

thank you
I'm interested in this topic, since nobody seems care that much to write up a friendly method to do that...
Not friendly
These guys claim to know these things but fail to even give a link to a tutorial on how to do it. Its infuriating. They tell us to research but asking here on XDA is part of research. Pls give a valid tutorial on how to secure prey data so it doesn't get deleted.

Titanium Backup is possibly the best app for a rooted phone. It will uninstall any app.
You can go into TWRP, mount System partition, then hit the FileManager under Advanced, and then change permissions/delete files/folders accordingly.
But be careful, there seems to be some wierd dependencies going on in there, and you end up with some random FCs here and there after removing bloat app folders and such.
My personal advice if you want to be free of headaches, just 'freeze' the apps using say 'Advanced Tools' from appstore (my recommended app freezer and general swiss-army tool).
