One of the first things I do with a new Android device is remove everything I don’t actually use. Modern Lenovo tablets are surprisingly clean compared to many competitors, but there is still plenty of software that can safely disappear.

This guide documents the process I used on the Lenovo Idea Tab TB336FU (Android 15 / ZUI 17). The same workflow is applicable to many recent Lenovo tablets.

No root required.

No custom ROM required.

No bootloader unlock required.

Before You Start

Enable:

  • Developer Options
  • USB Debugging

Verify ADB:

adb devices

Backup Package Lists

Always save the package list before touching anything.

adb shell pm list packages | sort > remaining_packages.txt
adb shell pm list packages -s | sort > system_packages.txt
adb shell pm list packages -3 | sort > user_packages.txt
adb shell pm list packages -f | sort > packages_with_paths.txt
adb shell pm list packages -d | sort > disabled_packages.txt

Safe Removal

These applications were removed with:

adb shell pm uninstall --user 0 PACKAGE_NAME

Examples:

  • Facebook services
  • Opera
  • Instagram
  • YouTube Music
  • Google TV
  • Lenovo What’s New
  • Google Feedback
  • Traceur
  • Google Restore
  • Gmail
  • Google Calendar
  • Google Maps

Safe Disable

These were disabled first instead of being removed:

adb shell pm disable-user --user 0 PACKAGE_NAME

Examples:

  • Lenovo User Experience
  • Lenovo Service Framework
  • Lenovo ID
  • Lenovo Tablet Center
  • Lenovo Weather
  • Google Assistant
  • Google Search
  • Meet
  • Drive
  • Photos
  • Digital Wellbeing
  • Motorola Ready For components

Packages You Should Leave Alone

If you use the Lenovo Pen, keep these enabled:

  • com.lenovo.penservice
  • com.zui.pengen
  • com.zui.notes
  • com.myscript.nebo.lenovo

Also avoid removing:

  • com.android.systemui
  • com.android.settings
  • com.google.android.gms
  • com.google.android.gsf
  • com.lenovo.ota

Restoring Packages

Packages removed with --user 0 are not permanently deleted.

Restore one:

adb shell cmd package install-existing PACKAGE_NAME

Re-enable:

adb shell pm enable PACKAGE_NAME

Debugging Running Services

List Lenovo services:

adb shell dumpsys activity services | grep -i lenovo

Inspect a package:

adb shell dumpsys package PACKAGE_NAME

Show APK path:

adb shell pm path PACKAGE_NAME

Show package permissions:

adb shell dumpsys package PACKAGE_NAME | grep permission

Memory usage:

adb shell dumpsys meminfo PACKAGE_NAME

Running processes:

adb shell ps -A

My Workflow

  1. Backup package lists.
  2. Remove obvious bloat.
  3. Disable questionable packages.
  4. Reboot.
  5. Verify pen, camera, OTA, launcher and Play Store.
  6. Only then consider permanent removal for the current user.

Final Thoughts

The TB336FU turned out to be much cleaner than expected. Lenovo separates many features into standalone packages, making ADB debloating relatively safe if approached carefully.

The biggest recommendation is simple:

Disable first. Use the tablet for a few days.

Only remove packages after you’re confident they are unnecessary.

That approach dramatically reduces the chance of breaking useful features while still ending up with a much cleaner Android experience.
