Remove preinstalled apps - Universal Android Debloater

I just discovered this amazing app! It lets you remove (or just disable) preinstalled apps like Facebook, Netflix, etc. and system apps like samsung knox apps, diagnostic, bixby, and even One UI (but you must have installed other launcher). You can’t brick your device, worst case it falls into a boot loop and after 5 reboots it will factory reset.

Debloating your device will make it faster, more private and more secure (less atack surface).

The gold standard is to flash a new ROM, but a lot of people dont’t want to, or cannot because either the phone won’t allow (Samsung etc) or it is too daunting. Next we had ADB commands via terminal (hello hours in the terminal). UAD in isolation might seem daunting, but compared to the alternatives, it it is a heaven sent gift, and I’m not even religious.

Always wondered how deeply these types of de-bloating systems affect the OS overall. I’d be keen to give it a go but phone stability is pretty paramount.

Apps that are considered “bloat” are of course installed to the system partition. Which is something you don’t have access to. The link to the app is created for your user account during device setup. It’s still available to the system. Without root access they’re not permanently removed. Removing them from your user means they don’t run. If there is an OS update that updates apps for feature or security reasons, they have the potential to come back. You must remove them again. It does actually save battery once they’re removed. You can verify this by using debug tools to look at all running services. You also don’t need this app to remove bloat. It just makes it easier for those who don’t want to use ADB command line.

A majority of apps won’t ruin your stability if removed. The only app I know I can’t remove is My Verizon Services. If I do, I lose certain functionality. If you’re unsure, look up what each app does.

Should be useful for phones with unlockable bootloader.

NateSwift ,

You don’t need to unlock the boot loader for this

I would use Lineage os

chevy9294 OP ,

That would also work, except for unsupported devices.

possiblylinux127 , avatar

True, I suppose

zwekihoyy ,

someone could make this a simple mobile app using shizuku so you don’t even need another device.

Cwilliams ,

Seriously this would be sick

RotatingParts ,

I’ve used this on my Samsung phone and I’ve seen better battery life with so much junk running in the background.

Been using this for a long time. Great tool. Great idea.

If for some reason you cannot get this to work on your system, the database on this GitHub is still useful for doing it manually.

Is this better, or just quicker, than going thru the apps in Settings>Apps one by one and hitting “Uninstall” “Uninstall” or “Disable” whenever the button is available?

Rin ,

some apps are installed by your system. you can only “disable” them through the settings but not uninstall them.

chevy9294 OP ,

And some you cant even disable

JubilantJaguar ,

Yes yes I understand that. But is this ADB trick anything other than a time-saver? As you say, they cannot be uninstalled either way.

RogueBanana ,

Adb commands can uninstall them instead of just disabling them, thats why you should try it

JubilantJaguar ,

Right. I’ve even done that in the past. Would be nice to see the evidence that uninstalling is any more useful than disabling.

RogueBanana ,

As in clearing space and simply off the list? Idk what else you are expecting…

Pantherina , avatar

Not every app is graphical. Not all can be disabled.

Using “package manager” from F-Droid you can list them and simply use adb uninstall --user 0 APP for all apps. Copy paste, appname, thats it.

Just be sure to keep the logs to reinstall when needed?

This is awesome.

One of the best decisions Apple ever made was not letting carriers and other OEMs install bloatware on phones out of the box.

@navi @chevy9294

Just all the apple bloatware lol

navi , avatar

Like what? Their office apps?

I do find it annoying to delete them on new phones.

izstranger , avatar


Apple maps

Jeez i didn't even know about office apps


insaneduck ,

Except safari you can uninstall rest

UsernameIsTooLon ,

The end result is a locked ecosystem though. The open source nature of Android makes this a bit harder to regulate for Google.

Also money money money

    Yea, hence money money money.

    But I more meant that Apple kinda has too much control over their own iOS. Google even allows different flavors of Android to exist like OneUI, NothingOS, or even all the Chinese ones too.

    I want to specify for anyone whom doesn’t know.
    ADB can’t actually “remove”/delete system applications from the devices storage. It can only “uninstall” them from the user account; that’s why you can’t brick the device with this method.
    So if you’re looking to free up space on the device you’ll have to find a different solution.

    Thanks for the awesome GUI tool.

    NENathaniel , avatar

    Do you suspect there are still benefits to doing this then?

    redw0rm , avatar

    Yes. Some of them do nothing other than serve ads and /or track information.Disabling them can help thus with better privacy and longer battery life.

    Rustmilian , (edited ) avatar

    Ofc. “Uninstalling” say the Facebook shitware that’s included in Samsungs from the user account prevents them from running. The apps are still very much in the system partition, but the user account will never run it because to the account it’s “uninstalled”.

    cyclohexane ,

    Storage-wise they’re there, but they never run or take up memory? Is this correct?

    Rustmilian , avatar


    kassuro ,

    Ah that looks awesome. Definitely gonna try that out. Thanks for sharing

    miss_brainfart , (edited ) avatar

    I’ve always done it manually and never knew there was an app for it, that’s so cool!

    You can’t brick your device

    Still, always good to do your research before removing a package that looks unnecessary but is actually integral to your system

    ComfortablyGlum ,

    How is a novice to tell?

    miss_brainfart , avatar

    Looking at the github page, the tool seems to come with certain lists telling you what is safe to delete based on what brand the phone is from or what carrier you’re using.

    I used it for the first time on my tablet. I went from LineageOS with unlocked bootloader to debloated Stock OS.

    I found it well documented. It has filters to mark apps for removal. You can be conservative or more aggressive. It tells you the purpose of each package and even if it unexpectedly affects functions that shouldn’t be linked to them at all.

    Having a way to reinstall Stock android is a good precaution though.

    Can this clean up my Kindle fire tablet from 2017?

    chevy9294 OP ,

    If it runs Android and if you can enable usb debugging in developer settings than yes, otherwise no.

    blanketswithsmallpox , (edited ) avatar

    Fire Toolbox is the only one that I'm familiar with. It's less cleanup and more hiding a bunch of stuff. Adding a bootloader and disabling some of the Amazon tracking.

    I don't think there's any programs that allow you to straight up nuke the Amazon firmware and side?load your own android or tablet OS.

    LazaroFilm , avatar

    I see I’m using Amazon toolbox and yeah it just layers a nice launcher and hides Amazon crap. Doesn’t really sets a clean android install. I would love a nuke option for these tablets.

    USSEthernet ,

    For Kindles, the Fire Toolbox will get you sorted if you’re below FireOS ……/windows-linux-tool-fire-too…
