Phone Presence Sensor delay

I have 2 phones that are same make and model as presence sensors. One works fine, as soon as the phone is no longer at the location that was set (home) the Smartthings app shows that it is away. The other phone however does not show away till much longer. The length of time it takes is not consistent but it is about an hour or more. Is their a setting on the phone that is causing this? or…?

iOS or Android?

Android Samsung S8

Has anyone found a fix for this? I have the same problem described here, except that my second phone sensor never shows “Away”.
