Ionic IBeacons

I have a question about the usage of this library:

I’ve been making an Ionic app and testing it on both a Samsung Galaxy Tab 4 and and Samsung Galaxy S6, and the time it takes for a beacon to be found takes very long…

I’ve been using this code as described in the documentation of ibeacon native and adjusted it to the application:

    (data) => {
            data.beacons.forEach(emittedBeacon => {
                          if ( (emittedBeacon.proximity == 'ProximityNear' || emittedBeacon.proximity == 'ProximityImmediate' ) && emittedBeacon.accuracy < 1.5) {

    error => console.error();

I’m using Ionic3
