Why can't I use my cell phone's GPS signal?

Episode 1346 (2:01:31)

Scott from Orange, CA
Apple iPhone 6

Scott has an iPhone 6 and he uses it to get around while hauling equipment, but lately it hasn't been working well -- ever since the last update. Leo thinks that Scott's iPhone has a damaged GPS receiver. He hasn't heard reports of GPS problems after updating, so he has a hunch it's a physical hardware issue. Scott should bring it into the Apple Store.
