Why my gps didn't function?

[AC Question]

Why my gps didn't function? I already on my gps but when I open my gps or waze it said that it can't detect my location and ask me to switch on my gps. I thought my waze didn't function properly and I tried to use google map and the same thing happens. They asked me to switch ony gps although I already on it. Please help, thanks.
