On Google maps on the watch 4 it keeps showing that I'm facing 180° (backwards) from where I'm looking towards. This happens often and makes walking navigation almost usless for me. Anyone else having this issue?
same. the GPS on the watch drain too much battery and is comparably less stable/accurate imo.
i know compass app is there but also not sure how accurate it is.
Try calibrating the compass in the compass app. Open the app and move your wrist in a figure 8 shape a few times if it doesn't already prompt you to calibrate it on screen
Maybe try force stopping the app. Under the watch settings in the app go to the "apps" tab, then go maps and force stop. Otherwise if that doesn't work, maybe try disabling it there and reenabling it.
