Despite many years of complaints, third-party OEMs still carry completely new devices. Even in 2019 you will still find lots of phones with Facebook pre-installed. What's worse, it's installed as a system app, so it can't normally be uninstalled without root access. However, there are some solutions.
How each manufacturer and operator installed their bloatware system apps varies, so we have three methods to help you remove Facebook and other system programs. We listed them in difficulty from most simple to the most complex, but the third method is the most surefire way. None of these methods uninstall the app. Instead, they will disable it, prevent background activity or new updates and remove them from your appbox. Essentially, the app is put on rest instead of being killed.
: Disable the app in settings
The easiest method is to disable the app within Settings. To achieve this, open the Settings app and select "Apps". On newer Android versions, you may need to tap "See all [x] apps" here to expand the list.
From here, select Facebook (or any system app you want to delete) to open its App Info page. There are two buttons at the top of the page, "Disable" and "Force Stop". Select "Disable" and press "OK" on the popup.
If the first method is not possible or you want to delete more than just Facebook, recommend we use a package update app. These apps can remove not only Facebook, but many of the bloatware apps that OEMs contain.
Currently, the only trusted applications are only available for LG and Samsung devices. The LG version costs $ 1.99 and its reliability varies. However, Samsung users should not have any problems, even if you are using the new Galaxy S9 or S9 +. Similar to the LG version, this app is not free, with a price tag of $ 3.49.
Method 3: Use ADB
The most difficult method uses ADB commands, but it is free and will definitely do the trick. Don't worry, but ADB commands are more daunting than complicated, as the process of deleting system apps is pretty easy.
The first thing you need is ADB installed and open on your computer. Use the link below if you don't know how to do this.
For proper communication between your phone and computer, you must install USB drivers for Windows devices. Use this link to find your phone OEM and follow the instructions for getting the right drivers. For Mac and Linux users, you can skip this step.
Next, on your phone, go to the Play Store and install the App Inspector. App Inspector gives you the exact package name on Facebook and any other system app you want to disable.
From here you open App Inspector and select "App List", then click on the Facebook app. The package name is located under the name of the app, starting with "com" or "net" followed by a series of words separated by dots.
Connect your phone to the computer and enable USB debugging. Enter the following command in the command prompt or Terminal, replace XX with the package name you just found.
adb shell pm uninstall -k - user 0 XX
Once you have done it correctly, you will see a message saying "Success," indicating that Facebook is disabled from your device. Note that this does not uninstall the app, as it will recur if you ever reset the device.
