Uninstalling
Preinstalled Android Apps without root
On my Moto G6 every Update seems to re-enable the Outlook
and linked-in in apps I disabled on purpose. You can not uninstall apps that
have been installed by the manufacturer via the play store or app settings,
only disable them.
So far I have been disabling them after each update but I
have gotten quite annoyed by it and did a little bit of research to find out
how to fully uninstall them.
Prerequisites
What you need is the Android Developer Bridge (ADB) on your
computer and you need to enable USB debugging on the phone.
I have used Windows in this guide but there is a great guide
on how to set everything up in Windows, Mac & Linux over at
XDA-Developers that walks you through the process.
USB Debugging on the Phone
If you haven’t enabled the Developer Mode on your phone yet,
you have to navigate to Settings, then System -> About and scroll down to
the buid number. Tap this 7 times to enable Developer mode.
Then You will find the Developer Settings in the Systems
Settings menu. Go there and enable USB debugging.
ADB on Windows
Setting up ADB on Windows is straight forward. Download
the latest
ADB version, extract the files in the zip and navigate in Powershell to the
extracted folder.
Tipp: You can hold down SHIFT when
right-clicking in Explorer and use “Open Powershell here”
From here you can run the adb commands. Since we did not add
the folder to the PATH we will have to preface the command with .\ to make it
use the adb.exe in this folder.
If you follow this guide on a different OS or have ADB in
your PATH you don’t have to use the .\
Connecting the Phone
Connect the phone via USB and double check that USB
debugging is enabled.
Then you check for connected devices
.\adb devices
This starts up the ADB service and lists connected devices
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
ZY322XXXX
unauthorized
On your phone you should get a pop-up asking you to confirm
the ADB connection to the computer. After accepting it
.\adb devices
Should list your device now not as unauthorized anymore.
List of devices attached
ZY322XXXX device
Listing the Apps
.\adb shell pm list packages
Prints out a long list of all installed apps. You can use
this list to find the full name of the apps you want to uninstall.

While you can uninstall most apps like linkedin and outlook
you should be more careful with system apps.
Uninstalling the App
.\adb shell pm uninstall --user 0 [Package Name]
Will uninstall the app. So in my case I just had to issue
.\adb shell pm uninstall --user 0 com.microsoft.office.outlook
and
.\adb shell pm uninstall --user 0 com.linkedin.android
Once ADB returns with Success you can unplug your device and
are done.
Remember to disable USB Debugging again in your Developer
Settings.
