Your position isn't updating correctly? Maybe your friends only see your real-time location when you have the app open?
If so, there's a good chance that battery-saving settings are enabled on your device. These settings can prevent Zenly from running correctly in the background. Therefore, your friends will only see your real-time location when you have the app open.
Please troubleshoot the following steps to ensure that battery-saving settings are disabled:
Android 7, Android 8, Android 9, Android 10
STAMINA > STAMINA level > Balanced power-saving OR Device performance preferred
OR you can access the STAMINA settings from 'Battery'
Ultra STAMINA mode should not be activated
If the above steps do not resolve your issue, please consult the article, "My location isn't updating – Android" for further help.
