After enabling developer options on the phone, connect the USB cable that came with the phone to the computer.
Start adb shell as follows:
cd android-sdks/platform-tools <enter>
./adb shell <enter>
Within the shell, you can execute several commands.
List all installed packages using the adb in android-platform-tools
pm list packages
List all files associated with a package:
pm list packages -f <enter>
This is an example to help block the My Xperia app from starting up on the phone.
You can look for My Xperia.apk and you disable it using:
pm block com.sonymobile.android.mx <enter>
Restart the phone.
You will not get My Xperia in the Apps list. I deliberately chose My Xperia as the example because the latest Android KitKat 4.4.4 upgrade on the Sony Xperia ZR installs a modified version of My Xperia service that without user knowledge installs a baidu folder on their internal storage. Sony is very silent on what that folder does or whether it is an official Sony feature or not.
