GPS module hardware location

Hello,

I'm searching for some info which can help me fix/repair my GPS functionality.

Cause: My S6 got little bit flooded. I brought it to service point in order to clean and dry it out. For sure there was SUB board replaced.

Problem: GPS is not working at all. Any application that require this functionality simply fails on GPS fix.

When an application starts, the little GPS bar icon blinks for 3 times and than just disappears.

Questions: Where is the GPS module/antenna located?

Is there a possibility to replace that module/antenna?

Or maybe it is integrated to motherboard?

Maybe service did some mistake like did not connect a wire or something...

Add on: All other radios are working correctly.

Firmware has been flashed (x2)

Any help will be appreciated.
