WARNING Uninstalling system applications can be dangerous so please know what you’re getting rid of before you complete these steps. Failing to do so could result in your phone becoming unusable until you perform a factory reset. Of course, by removing any given system application, another system application that may depend on it may also break so be careful what you remove.
Install the USB drivers for your device (Google has a list of some universal USB drivers here)
Download the ADB binary for your particular OS (Windows, Mac, Linux)
Extract the zip file into a folder that you can quickly access.
On your phone, go to Settings and tap on About Phone. Find the Build Number and tap on it 7 times to enable Developer Options.
4.
Now enter Developer Options and find USB Debugging. Enable it.
5.
Plug your phone into the computer and change it from "charge only" mode to "file transfer (MTP)" mode.
6.
On your computer, browse to the directory where you extracted the ADB binary.
7.
Launch a Command Prompt in your ADB folder. For Windows users, this can be done by holding Shift and Right-clicking then selecting the “open command prompt here” option.
8.
Once you're in the command prompt/terminal, enter the following command: adb devices
9.
You will see that the system is starting the ADB daemon. If this is your first time running ADB, you will see a prompt on your phone asking you to authorize a connection with the computer. Grant it.
10.
Now if you re-run the adb devices
command, the terminal will print the serial number of your device. If so, then you’re ready to move on.
11.
Enter the following command: adb shell
12.
Execute the pm list packages | grep '<OEM/Carrier/App Name>'
command to find package names.package list
ALTERNATIVELY: You can also easily find the package name of an installed system application by installing the App Inspector app on your phone. I prefer doing it this way so you know exactly what the app name is of the application that you are about to uninstall.
If you have App Inspector follow the steps below:
Step 1: Tap on "App List"
Step 2: Find the app you want to uninstall. (eg. "Compass")
Step 3: Find the package name under the App Name (eg. "com.huawei.compass")
Execute the command like so: pm uninstall -k --user 0 <name of package>
command to uninstall a specific system application.
