Ionic 3 : geolocation isn't stable across the different Android versions - ionic-framework

Question

I'm working on an Ionic project based on geolocation and after testing my App on four real devices, I distinguished three different behaviors:
1) Android 4.x ( J1 Samsung) => works Correctly
2) Android 5.0.1 => The first time I install the App all works as expected but when I disable GPS and enable it again, the geolocation returns a position which is far about 1Km of my position and it still bugged until I restart the Phone and then it works correctly again until I restart GPS.
3) Android 5.1 => Same scenario of the Android 5.0.1 but after turning GPS OFF and enabling it again, the geolocation still returning an error "timeout" until I restart the Phone.
Please, I have to know if there is no solution or I can continue with this plugin?
Home.ts:
import { Component, ViewChild, ElementRef } from '#angular/core';
import { NavController, Platform } from 'ionic-angular';
import { Geolocation } from '#ionic-native/geolocation';
declare const google;
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
#ViewChild('map') mapElement: ElementRef;
map: any;
constructor(public navCtrl: NavController,
private platform:Platform,
private geolocation:Geolocation) {
}
ionViewDidLoad(){
new Promise(resolve => {
setTimeout(() => {
this.initMap();
resolve();
},2000);
})
.then(()=>{
setTimeout(() => {
this.getGeolocation();
},2000);
});
}
initMap() {
// map implementation
}
getGeolocation(){
this.platform.ready().then(() => {
alert('start geolocation');
var options = {
timeout: 20000,
enableHighAccuracy:true,
};
this.geolocation.getCurrentPosition(options).then(resp => {
alert('done');
console.log(resp.coords.latitude);
console.log(resp.coords.longitude);
let origin = new google.maps.LatLng( resp.coords.latitude,resp.coords.longitude);
this.addMarker(origin);
this.map.setCenter(origin);
}).catch((error) => {
this.debugError(error);
alert('error geoloc');
});
});
}
addMarker(location) {
//addMarker implementation
}
debugError(object){
var output = '';
for (var property in object) {
output += property + ': ' + object[property]+'; ';
}
alert(output);
console.log(output);
}
}
