xamarin.android - Android Geofence Trigger Delay/Failure -

i've registered geofences in android app 5-6 locations.

the geofence event want, geofence dwell loitering delay of 10 sec.

but using this, event triggered in android devices, , doesn't trigger @ in others.

so, testing purpose, considered below listed scenarios:

1) reduced loitering delay 3 sec. time results better, triggered in 4 out of 5 devices.

2) testing scenario was, registered geofence enter event (which has no loitering delay), , time triggered in devices.

ideally, need geofence dwell event triggered delay of 10 sec, because don't entertain frequent geofence notifications on enter event.

please suggest possibly wrong geofence dwell longer delays. appreciated.

thanks in advance.
