"It's sickening to think I've been using this phone near my face when it was used to take all of these photos," said the startled customer, speaking to the Australian Daily Telegraph. "What would've happened if that phone was bought for a child?"

The store has asked to see the images, and is investigating the matter.

"We take any incidence of this nature very seriously and we will investigate it fully," says a spokesperson. "We've asked the customer to bring us the phone to ascertain the nature of the images."
