Good idea, thanks for sharing. I act more or less similarly, switch off automatic updates and run regular backups.
On my Android devices I use TotalCommander
https://play.google.com/store/apps/detai...lCommander
to store the MobileSheets APK together with my MobileSheets backups.
To re-install a stored APK the file manager that came with the device is required. Alas Google forced Total Commander to remove the "install APK" feature that was available long ago and worked fine.
