GPS and Microphone issues

[Nakku]

Hello everyone, I had bought a Samsung s23 FE when I had come to Australia in February. The phone works well however I always face issues with the gps calibration.. It shows me somewhere else or facing a different direction. Have to recalibrate it everytime before using.

Lately have also been facing issues with the microphone not working very properly, for example if I pick up a call it takes 2-3 seconds for it to start working sometimes, till then no matter what I say the opposite person can't hear. 

Wanted to know how I could solve this.

Google Maps isn't the best, but enabling Wi-Fi scanning will help a lot.
I had the same issue using Google Maps on all my previous phones and still have it on my regular S23, so it's not about hardware issues; it's the app!
