How can I remove these apps from my device? I am trying to remove the Facebook and Messenger apps from my Asus Zenphone Laser 2.

Unfortunately, in both cases, I seem to be unable to find the option to fully delete them from the device. I have disabled them, but the app management screen now shows the following:




How can I fully delete/uninstall them?
You can't remove those apps from firmware without root but you can uninstall any system app for current user or any user using ADB.

Assuming ADB is installed and PATH is set if not you can do it with a simple internet search.

Steps:


Obtain package name for app you want to remove.
Open Terminal/Command Prompt
Make sure device is connected by running adb devices -l
Run adb shell pm uninstall --user 0 &lt;package name&gt;
Done


Package Name

Facebook: com.facebook.katana

Messenger: com.facebook.orca



Proof of Concept

After some discussion in the comments I'm adding an example here that worked for me. I have uninstall Google Keyboard from my device for current user using  command adb shell pm uninstall --user 0 com.google.android.inputmethod.latin
