http://www.terrisgps.com/gnss-gps-differences-explained/#:~:text=GNSS%20stands%20for%20Global%20Navigation,users%20to%20determine%20their%20position. The s20 has the new Dual GPS technology, much more accurate. Samsung has informed me that none of the S20 phones come with a compass app. I don't want to have to purchase, download a compass app, and then test to see if it is actually better\more accurate than the single gps chip on my older s7 phone (and if not, pay $50.00 for a restocking fee).
Has anyone purchased the s20, added a compass app, and tested against an older single gps phone (like point to true north (0 degrees)), to see if they are point pointing to the same spot on the horizon?
