What to do if my trackers keep losing Bluetooth connection

if you are experiencing an unstable connection between your Bluetooth and your phone, you will see dashes in the place of your run data and your left tracker will flash green as normal, while your right tracker will flash green and blue. If you experience this, your trackers will still be recording your run and you should be able to start and stop your run using the Activity button on your trackers. To stabilize your Bluetooth connection, you should try clearing your Bluetooth app cache

Older cache files and Bluetooth files imported from other devices can sometimes cause the Bluetooth module to underperform. Fortunately, there is an easy way to deal with this by clearing out the cache of the Bluetooth app.

For Android phones

1. From the home screen, head over to the Settings and then scroll down to Apps.
2. Press the three-dot menu button on the top and select Show system apps from the drop-down menu.
3. Scroll down and select Bluetooth from the list of apps.
4. Select Storage and press the Clear Cache button.
5. Then restart your phone.
