Samsung says 25 million of its phones have Carrier IQ
components of Carrier IQ and could trigger some of the available CIQ detector apps. However, the software on these units is dormant and there is no word on whether or not this software will be removed from the phones. Samsung's official comment on this reads, "Because the CIQ agent and other required CIQ software components are not installed, however, these vestigial elements do not and will not function on these devices, and therefore, the devices do not transmit (and never have transmitted) any user data using any CIQ software functionality."
While there is no word on which phones have the dormant CIQ code, Samsung did release a list of its Android models that contain Carrier IQ. Those models include the Samsung Galaxy S II Skyrocket for AT&T. Sprint models include the Samsung Moment, Samsung Epic 4G, Samsung Intercept, Samsung Transform, Samsung Galaxy Tab (original 7 inch model), Samsung Galaxy Prevail, Samsung Replenish, Samsung Conquer 4G, Samsung Transform Ultra (Boost Mobile) and the Samsung Epic 4G Touch. A pair of T-Mobile branded Android phones end the list, the Samsung Galaxy S II and the Samsung Exhibit II 4G.
