My phone is rooted with Magisk. I have a root browser app, allowing me to "sneak peek" into the root directories.

I found, for example, that for the Google Drive app, the APK in /system/app is 23MB, but application manager shows the app size as 30MB (excluding 750KB of data). Where is the rest 7MB gone? If I debloat the Drive app, I know I will not be able to use the 23MB as that is in the system partition, but will I recover this 7MB?

  • Check these folders /data/data/com.google.android.apps.docs and Android/data/com.google.android.apps.docs (internal storage or SD card).You will get the 7Mb back. Force stop the app, clear data and cache and then debloat. – Reddy Lutonadio Aug 25 '19 at 14:01

  • if your phone is rooted install Link2SD it is great in showing size and folder names i use the free version for managing my apps (search/sort/share/clear/freeze) you don't even need the second ext4 partition or linking functionality – alecxs Aug 25 '19 at 15:18
  • Is the Google Drive app active or disabled? If it is active most likely an update is installed and the app on system/app is not used at all as the update installs like a regular app in /data/app. – Robert Aug 25 '19 at 15:31
  • @Robert it is disabled. – Wrichik Basu Aug 25 '19 at 15:39
