Shizuku guide

Phones

Lenovo tablets

Lenovo tablets are close to plain Android. Lenovo's own page is old, so check the path on your tablet.

On this page

1. Turn on Developer options

  1. Open Settings.

  2. Go to Settings, then About tablet (some use Settings, then System, then About tablet) and tap Build number 7 times.

  3. Enter your PIN if asked. You see You are now a developer!

  4. Developer options is in Settings, then System, then Developer options.

4. Keep Shizuku from stopping

  1. Open Settings, then Apps, then Shizuku, then App battery usage and choose Unrestricted.

  2. Set Developer options, then Default USB configuration, then No data transfer. That fixed Shizuku stopping when the screen turned off on a Lenovo tablet with Android 13.

Also do the four steps every phone needs: unrestricted battery, Disable adb authorization timeout, No data transfer as the USB default, and leaving debugging on. They are on the Wireless page.

6. Turn it all back off

  1. First, in each app that used Shizuku, undo what it changed, while Shizuku still runs. Some changes an app makes through Shizuku stay after Shizuku stops. Firewall and Fileglow have their own steps.

  2. In Shizuku, switch off every app in the list of authorized apps.

  3. Stop Shizuku with its stop option, or restart the phone.

  4. Open Developer options, then Wireless debugging, then Paired devices, tap the shizuku entry, then Forget.

  5. In Developer options, tap Revoke USB debugging authorizations. This removes every paired computer and device.

  6. Turn off Disable adb authorization timeout if you turned it on, and set Default USB configuration back to File transfer if you want.

  7. Turn off Wireless debugging, then USB debugging.

  8. Turn off the switch at the top of Developer options: Settings, then System, then Developer options.

  9. Set Shizuku's battery setting back to the default (Optimized) if you like.

  10. Uninstall Shizuku the normal way if you don't need it any more.
