Heading or Bearing

I noticed that after the update, the client no longer sends the device heading. How can I fix this?

You mean it's sending zeroes?

I mean it's sending nothing :(

I should add that this is on Android. All the other data—coordinates, speed, and altitude—is being sent correctly.

Do you have logs?

// Read Traccar body
            String raw = request.content().toString(StandardCharsets.UTF_8);
            System.out.println(raw);

If it's missing, it means that the phone doesn't provide this information. Which usually means cell or wifi-based location.

this happened after the update, it was before

From what version to what version?

I noticed this 2 weeks ago.

any solutions?

This simply means your device is not providing GPS location. What accuracy are you using?

highest, early was heading :)

Highest usually gives GPS when available. This sounds like a phone issue to me.

i have this problem in few phones
