Do you know what Toast means in this case?
Done and Success are statuses after a notification. Done means it finished, success means it was successful.
Again follow the pattern. It pulled a log, that finished successfully, it then copied that log, which finished and was successful.
None of these things you're bringing up are important. They are all background noise, regular activities of any device.
And to Luara Knotek's point, why are these all external pictures and not screen shots? I hadn't thought of it prior to this but Luara is right, we maybe shouldn't be discussing this if you're snooping through someone else's phone...
