Fitbit Charge 2 link to phone GPS broken by ABS

Hi,

My first post to this forum, or any support forum that is. But now looking for help from people more knowledgable than I am.

I have a Fitbit Charge 2, a fitness tracker, that links to my Android phone GPS in order to measure distances on runs, walks, etc.

Connecting the Fitbit is no problem, but maintaining the GPS link is. ABS seems to be shutting down some component that is essential to keeping the link between the Fitbit and GPS positioning live.

I have uninstalled ABS temporarily and the whole thing now works fine.

The question then arises, what components, apps, etc, must be optimised in order for the link to stay live? I’ve tried all the usual suspects (Fitbit app, location services, etc) but the link is still being broken. Any ideas, anyone? Your help is very much appreciated.
