My GPS is not working. If I use Google Maps, it shows approximately where I am, but not as exact as I would expect. Turn by turn navigation isn't working either.

I've tried everything possible that I can think of (yes, been googling and youtube'ing).

I've downloaded an app called GPS Status and it shows that I don't connect to any satellites (it says 0/0 under Fix/Sats.).

I'm starting to think that the GPS antenna is faulty, but my colleague says that there's no actual GPS antenna in the S7. Is that true?

Also, I've tried *#0*# and Sensor.

Every time I switch the phone off, I have to recalibrate (to get the blue line). But GPS still doesn't work afterwards. Not sure if it has an impact?
