Good point, I&#x27;m assuming things here and should have made that explicit.<p>It&#x27;s pretty rare to have this kind of thing done on the device these days, but this example has a trade-off between the app using a lot of battery and using a lot of bandwidth so it&#x27;s possible something else is going on.<p>You could probably get a good idea just by monitoring bandwidth usage while this feature is processing a new picture.<p>Perhaps I&#x27;m too used to the standard approach of &quot;slurp everything because the users won&#x27;t know or care and we can use that personal data to train models&#x2F;sell&#x2F;etc.&quot; and very biased against Facebook when it comes to privacy issues.
