You will find a piece of Info called "Build Number" or "Build"
Tap that Text 7 times. After 4 Times you will see a small piece of text in the bottom half saying "in 4 steps you are developer"
After the 7th tap, you will have enabled developer mode; Do not panic, this hasn't done anything to your device yet but will simply enable you to do more with your device if you chose so.
Go into your Android Settings again
System
Developer Settings
9 Scroll down and enable "USB Debugging"
Connect your Phone with a good (ideally the original one) USB cable to your PC.
Open the command line (Windows+R -> cmd -> Enter)
type in adb devices
On your phone -> Accept connections from this PC
Now type in adb shell pm uninstall --user 0 com.google.android.youtube
You're done - Youtube is now uninstalled.
You can do Step 15 for all other bloatware aswell. There is a handy dandy application on https://github.com/0x192/universal-android-debloater that will let you use a nice GUI to do that. Debloats your phone quite effectively.
After you're done with all this, simply go back into your developer options and disable USB Debugging. That's it.
Got it, nice Automation 👍
