Similar to this, but Google has somehow wormed their way around my settings:
- Photos → Settings → Backup & sync is off.
- Photos → Device folders → Camera → Back up (sic) & sync is off.
- Camera → Settings → Data storage is set to "Save picture to phone."
Even so, this morning I got a creepy reminder that Google Photos has my image, and that they have "helpfully" post-processed it. Short of breaking my phone in half (or rooting it), how do I stop this from happening?
