Despite years of user complaints, OEMs still install third party apps on brand new devices. Even in 2019 you will find many phones with pre-installed Facebook. Worse yet, it is installed as a system app and therefore can not normally be uninstalled without root access. However, there are a few workarounds.
How each manufacturer and operator installs his Bloatware system apps varies. Therefore, there are three ways to remove Facebook and other system apps. We listed them in order of difficulty from the simplest to the most complex, but the third method is the surefire way. None of these methods uninstall the app. Instead, they are disabled, which prevents background activity or new updates from being removed from the app drawer. Mainly the app is put to rest instead of being killed.
: Disabling the App in Preferences
The simplest method is disabling the app in Preferences. To do this, open the Settings app and select "Apps." In newer versions of Android, you may need to tap on "All [x] Apps" to expand the list.
Select Facebook (or the system app to remove) to open the app information page. At the top of the page are two buttons: Disable and Force Stop. Select "Disable" and click "OK" in the popup. If the Disable button is disabled, use one of the following methods.
If the first method is not possible or you have more than just Facebook We recommend that you use a package deactivation app. Not only can these apps remove Facebook, but many of the Bloatware apps used by OEMs.
Currently, the only reliable apps are only available for LG and Samsung devices. The LG version costs $ 1.99 and the reliability varies. However, Samsung users should not have a problem, even if they are using the new Galaxy S9 or S9 +. Similar to the LG version, this app is not free at $ 3.49.
Method 3: Using ADB
The most difficult method is to use ADB commands , However, it is free and will definitely do the trick. Do not worry, ADB commands are more daunting than complicated, as removing system apps is fairly straightforward.
The first thing you need is ADB, which is installed and open on your computer. Use the following link if you do not know how to achieve this.
For proper communication between your phone and PC, you need to install USB drivers for Windows devices. Use this link to find the OEM of your phone and follow the instructions to get the correct driver. For Mac and Linux users, you can skip this step.
Next, go to the Play Store on your phone and install App Inspector. App Inspector gives you the exact name of the package from Facebook and any other system app you want to disable.
Open App Inspector and select "App List". Then tap on the Facebook app. The package name is under the name of the app and starts with "com" or "net", followed by a series of words separated by periods.
Now connect your phone to yours PC and enable USB debugging. Type the following command at the command prompt or in the terminal and replace XX with the package name you just found.
adb shell pm uninstall -k --user 0 XX

Note that this will not uninstall the app as it will be returned when you reset your device at the factory.
