Location on 1 device changes every minute or less

Hi,
I have 2 devices, android 10 phone and android 9 tablet. On both I have installed latest stable HA app, set with same settings. Both are excluded from battery optimisation. The tablet and phone are in same room, the tablet’s location history is continuous bar of being at one address.

However the phone’s location history looks like this: https://turbomrak.o5.ddns.net/s/bYkGzbGkgiiQbbT
(link on my nextcloud the img wouldn’t upload here)

Any setting I can adjust to make the location not spazz out?
