It is not uncommon for users to go through and �clean up� or delete data that they do not want to leave behind on smartphones. This can include selectively deleting messages, clearing device cache, or browsing/chat history, deleting media files or databases, installing third-party cleanup utilities, removing entire applications directories, or even invoking a device wipe.

A completely clean device may look suspicious, but there are many legitimate reasons that may cause a user to wipe a device. Based on just the data left on the device, we may be able to get a good idea of when the wipe occurred.
