Tracking randomly stops during the hike, despite Android settings all off

[markfilius]

Recently the app has become unreliable, i.e. the tracking during the hike will just "stop". Normally that can be Android behaviour to save battery, but those settings are all off:
* location allowed all the time
* app management is off
* background activity allowed.

One screenshot shows that tracking started, but then just stopped. Other screenshots show settings.

There has been an update to the OS to ColorOS16 (the phone is an Oppo Reno).

Please advise if there is a solution for this!

Hi markfilius,

thanks for the report and the screenshots. Oppo's ColorOS is known for stopping background apps aggressively, and a recent update can reset or add settings, so it's worth checking a few more places than the ones you listed:

Lock Locus in Recents. Open the Recents screen and lock the Locus card (the lock option in the card's menu). Locked apps are skipped by the system cleaner. This helps most often.
Battery > Locus Map (App battery management). Set it to "Allow background activity" and "Allow auto launch".
Sleep standby optimisation. Turn it off (Settings > Battery > More settings), as it can cut GPS and services while the screen is off.
Pause app activity if unused. Turn it off in Locus' app info, if present.
Location. Keep "Allow all the time" and "Use precise location" on.
Notification. Keep the Locus tracking notification enabled, and don't minimise or hide it.
