GPS searching continuously on my Google Maps

[Android Central Question]

My google maps showing greyed out "Seaching for GPS"
I don't get any turn by turn directions. Have done factory reset and had my phone Samsung S8 sent back to samsung repair for testing, they couldn't be find any fault with GPS, this issue is doing my head in, any help would be appreciated.

Open the Phone, as if you were going to make a phone call and dial -
*#9090# -- Diagnostic Configuration (*#197328640# if that doesn't work)
Menu, select Key Input, enter Q
Menu, select Key Input, enter 0000
Wait for the next menu. (It takes a while.)
UMTS->COMMON->NV REBUILD->NV REBUILD->SYSTEM->PROTOCOL->GPS->IMS
or, if you don't have UMTS:
UE SETTINGS & INFO->SETTING->SYSTEM->NV REBUILD->ALL

Restart the phone.

Also, install GPS Status & Toolbox so you can see what's actually happening with the GPS receiver.

I have a S8+ and the commands Key Input, enter Q and Key Input, enter 0000 do nothing to me. I know that it takes a while, but nothing shows up here... Is there any updated command?

Thank you very much!
