Most people have something to hide, and a new survey finds that to be the case when it comes to smartphone owners and their content.

A survey commissioned by the mobile security firm NQ Mobile finds 87 percent of consumers have content on their smartphones that they’d rather keep private.

The content includes family photos, private contacts, office documents, flirty texts and downloaded media.  Fifteen percent of respondents also admit to keeping private, sexy photos of themselves on their smartphones.

Still, despite the large amount of private content, the survey finds that only 53 percent of smartphone owners secure their devices with a passcode.

The NQ Mobile survey involved 1,000 U.S. adults.
