GPS Problems Samsung Galaxy S5

So with the GPS on my S5 I can get a fix on Here Maps/Google maps, but when I try to use GPS Status Free I can't get any satellite fixes. Pretty much the same as this issue(Note this isn't my video).

I have tried updating the A-GPS data, and it didn't change. This is the same whether I have High Accuracy on or not. I have gone through the FAQ, and apart from leaving my phone out in the sun for 15 minutes it hasn't worked.

I've tried to access the #1575#, ##1575##, and ##1472365##* menu's but I can't get to them. I spent ~30min on live chat with Samsung support and the most they offered was for me to do a Factory Reset.

Technical data on my phone:

• Model SM-G900I (Samsung Galaxy S5 16GB)
• Android Version 5
• Kernel Version 3.5.0-5543425
• Located in New Zealand, outside under blue sky day.
