Geolocation was not working on some Android Devices

Ionic Framework ionic-v3
1

Just use same code from Ionic Native Docs

import { Geolocation } from '@ionic-native/geolocation';

...

constructor(private geolocation: Geolocation) {}

...

this.geolocation.getCurrentPosition().then((resp) => {
    console.log(resp.coords.latitude);
   console.log(resp.coords.longitude);
}).catch((error) => {
  console.log('Error getting location', error);
});

All Test on REAL Android Devices

Some devices work, but other not.
Is it the Plugin Problem ?

Anyone has same Issue ?
Any Solution ?

Thx
