Download one of the apps that shows individual GPS satellite signal strengths and tell me if you still believe this. Definitely not true for my phone.

It really depends. I have an older dedicated GPS receiver that absolutely no way will receive a signal indoors. My iPhones all do a pretty good job. (FYI, you can only get signal strength on an Android phone; Apple's CoreLocation API doesn't provide that or some of the other detailed satellite data.)
