My samsung galaxy s10e developed a problem around 2 weeks ago and now my location is constantly jumping between my real location and a quite specific location on my city (around 10km away). The accurary is still reported as my exact location (e.g. google maps doesn't show the accuracy-related blue circle at all).
Before this problem started, I had problems when I was navigating along a road with google maps, my location would be constantly ~50-100m next to the road so it was basically impossible to navigate in the city centre due to google maps thinking I was driving on the street next to me.
This is a really frustrating problem, so any help is very greatly appreciated!
Open Settings. Search "Optimize battery usage". Check if Maps is in the Apps Not Optimized List. Also, check if the app is not in the list of always sleeping apps in device care > battery.
and you can use "location accuracy"apps to increase GPS accuracy. Link below.
hope this was helpful.
