Nope there is nothing you can do except wait for Samsung to send out a software update eventually. I tried that GPS fix app that everyone keeps recommending and it worked a little bit the first time but now doesnt do anything. So we just gotta wait.
My GPS location is extremely inaccurate a lot of the time and sometimes puts me more than a half mile away from my location. Restarting the phone does not always help and clearing location apps cache doesn't either.
Having issues with the GPS accuracy on my S20+. Based on a web search, it appears this is a pretty wide spread issue with these phones. I've tried some of the suggested "fixes" but none have worked. It's disappointing and frustrating that the device doesn't work properl , especially considering the price tag.
This is happening in every app that uses GPS. I'm sitting at home and the GPS has my phone more than 0.5 miles away.
