I noticed an odd behavior in Android. I don’t use some of the Google apps like Movies & TV so I disable them. However, on my Note 4 I noticed that they were apparently being re-enabled the next time Play Store/Services checked for updates. I also noticed this on my work-provided Galaxy S6 and soon figured out what was actually happening. At the time I didn’t know if it was due to something Samsung had done or if it was Android, but now that I’ve experienced it on my Ellipsis 8 I know that it’s the latter. For reference, the Android versions are 5.0.1, 5.1.1 and 4.4.2, respectively.
When you tap “Disable” on the app it will ask if you want to uninstall the updates. From what I can see, if you click “cancel” there the entire operation aborts – doesn’t uninstall and doesn’t disable the app. However, if you click “ok” on the uninstall that is all that it will do – the app will remain enabled but disappear from the Downloaded list since it has reverted to the stock or bundled version. You need to go to the All list and disable it there.
