Question: iPhone 6S - GPS + Cellular Doesn't work together
Since iOS 11.2.4, my phone doesn't work with GPS like it used to.
So starting an app like Strava, Waze, Apple Maps works to locate me. As soon as I start using GPS exclusively (start a navigation route, start recording a bike ride), about 20 seconds later, GPS stops working, the phone can no longer locate my location, and the cellular no longer has service "no service".
When this occurs, if I enable airplane mode, and turn it off. The phone immediately has 4 bars of service, navigation starts back up for about 20 seconds before the same thing happens again. This is consistent and happens any time GPS is used with cellular data. On Wifi, it works fine.
I have tried reseting, hard reset, and even a factory reset.
I need suggestions please.
iPhone 6s, iOS 11.2.6
