This warning happens when taking a photo for a survey, but it doesn't happen every time. The warning message is: "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates."

The logs are as follow: 2014-02-17 17:48:40.182 Paco[7761:60b] Self-report 2014-02-17 17:48:43.622 Paco[7761:60b] Snapshotting a view that has not been rendered results in an empty snapshot.

@yimingcheung : the error shows up when device is help in landscape position and camera is opened up.
