When I'm not in a phone call, normally when I have my finger over the proximity sensor it triggers the dashboard (I have shortcutd set to trigger the dashboard). Sometimes I can get it to work, sometimes I can't.

Though I don't know if this is related to phone speaker switch, hence my post asking if anyone else using shortcutd for its proximity features has unreliable detection. Not sure if it's just my device or an actual conflict between the apps.
