In Android 7.0 Nougat on Samsung devices, you can go to Settings -> Clouds and accounts -> Accounts -> Google to see a list of all the Google sync options.
Sync Calendar says "Tap to sync now" with "Last synced date" of when I factory wiped the device.
Sync Contacts is the same as Calendar.
Sync Google Fit data is the same as Calendar.
Sync Google Play Books says "Tap to sync now" and "Sync turned off".
Sync Google Play Movies & TV is the same as Play Books.
Sync Google Play Music says nothing under it.
Sync People details says "Tap to sync now" with "Last synced date" of today!
Sync Play Games Cloud Save is the same as Calendar.
There are no enable/disable toggle checkmarks next to any of the items.
In Settings -> Clouds and accounts -> Backup and restore -> Back up my data is turned off.
I want all syncing with Google to be turned completely off, and any synced data to be deleted.
The exceptions are for Books, Movies & TV, and Music, for which I would like to manually sync once in a while.
How can this be done?
