That is in fact remarkable. In the 8 years I am using Xperia X, XA2 and 10 III I constantly used all the phones for navigation throughout Europe. After a few years the antennas of my XA2 degraded (There is a fix for that. Clean the contacts and it works again.) Edit: Link to XA2-Fix: [How-to][Hardware] Fix XA2 GNSS(GPS): Let's Try harder
Since eight years GPS works as it should over three different devices on a more or less daily basis. It’s GPS after all so it does not work inside buildings and it takes some time to get a fix esp. after e.g. landing in a different region. But it works.
As well as SMS btw. I cannot say anything about MMS since this service is obsolete for years and Vodafone Germany sends you an SMS with a pointer to a website, where your MMS content is temporary stored,
My phones always had a stock setup. No hacks, no patches no magic. Bought them, flashed SFOS and used them.
