Eric Schmidt says Google doesn't support or work with Carrier IQ16
At an Internet freedom conference in The Hague in The Netherlands, Schmidt explained that because Android is an open platform, bad software can be put onto devices. He goes on to say that Carrier IQ is one of those bad pieces of software, which will keep your keystrokes. But, he adds that Google doesn't work with the company, nor does Google support the software.
We'd have to believe Google on this one, because even on carriers like Sprint where Carrier IQ has been found on many devices, the software has never been found on a Nexus device.
