My new S20 has very slow and unreliable GPS lock issues.  Google Maps & Waze frequently show my location 1-2 miles away even outdoors in clear conditions.  GPS games also show the incorrect location or jump around frequently.  Sometimes a reboot fixes the issue temporarily but eventually it returns.  I didn't have this issue with the S10, this is really a terrible bug to have in a new flagship phone!  Is there an incoming fix or information on this problem?   Update on 3/15/2020:  I chatted with a Samsung support person via the chat option on the website.  They had me calibrate my GPS from the Edge menu.  Note that on my phone I first had to enable the edge menu.  Once enabled swipe left to bring out the menu, and most importantly go to the little dots in the lower left and swipe again to get the "second level" edge menu (or second page).  Poor UI but it's there- a second page that has "Calibarate" Tally Counter, Flashlight, Surface level and Ruler.  Choose Calibrate and move phone in a figure 8 to calibrate.  I will retest out in the field and report back. Note that on some carriers (not verizon) you can enter *#0*#, then tap Sensor, then Selftest under magnetic sensor and ensure it says "Pass".  Fingers crossed!   Update 3/18- none of the solutions in this thread has worked reliably for me.  If you google "galaxy s20 gps issue" you'll see growing coverage of this issue so hopefully it will get a solution soon.   Update 3/29- I received a system update a few days ago (G981U1UEU1ATCH/G981U1OYM1ATCH/G981U1UEU1ATCH)  but unfortunately the problem is still occuring and not fixed.  Update 5/10- It's working much better now, some sort of update must have been pushed and in conjuction with keeping 5G off I'm finding GPS pretty reliable now so am closing this issue.  Hopefully it will get fine tuned and even better.   Update 9/15/2020- I see many people are having this issue again so am unmarking it as solved.  I am not experiencing the issue anymore but others are.   ...
