What a mess!

I bought the 30th anniversary edition and I had to change it because the GPS has a 20-meter displacement of reality. The new phone presents the same problem, but ASUS Spain says that it does not know this problem.

Is it possible to fix the problem or do I return the phone?

I have compared with Zenfone 5z and there is no problem.

You mean that both are acting in the same way and that there's no problem with your ZenFone 6 or did you mean that there's no problem with your ZenFone 5z?

With the two phones together. The ZF 5Z works correctly. The ZF6 does not work properly.
Test with Geo Tracker.

I have requested the return of this phone of such low quality.
-GPS Dual with less precision than a GPS from 20 years ago.
-Proximity sensor that constantly fails and proca pulsations on the screen.
-The sound cancellation during the call does not work, and the person you speak with does not listen to you.
What a mess!

I have an Expedition 30, it has worked fine with Google Maps.
Now I compared GPS with my old Xiaomi Mix1, using the app GPSstatus.
The Z6 sees twice as many satellites (40) and gets twice as many fixes (20) as the Mix1, and shows "Error" of ~ 5 meters where the Mix1 shows ~ 10.
You could run this app and see what you get to compare.
With the app you can force refresh GPS data.
