Location updates sometimes way off (100+ km)

See original GitHub issue

Home Assistant Android version: 2.4.0-full

Android version: 11

Phone model: Google Pixel 3a

Home Assistant version: 0.114.4

Last working Home Assistant release (if known): 2.3.3-full

Description of problem: Location updates is sometimes way off. Today I noticed that Home Assistant reported me in a location about 110 kilometers away. According to the logs HA was convinced that I was located there with several location updates with good accuracy during a period of an hour.

The strange location was set at 09:03, and reset to my real location at 09:54.

The only thing that stands out is that altitude, course and vertical_accuracy is all 0. Can it be some sort of IP geolocation update?
