Hi guys

I was playing around with a GPS blocker today.

To test it I used a android phone with a GPS satellite checker.

As soon as i plugged in the blocker I could see all the satellites start disappearing and they they al came back when j unplugged it.

So I thought it was working very well.

But then I opened my maps app and it immediately found my location. I then opened the Pokemon go game and again it immediately found my location. The same thing happened on Apple devices.

I even tried turning off wifi...etc and turning the devices off while I changed my location.

So my question is, how can these apps find my location if the device can't connect to any GPS satellites?
