Geolocation.watchPosition on device does not fire in conjunction with frequency value

Hi there

I am using the watchPosition function of Ext.device.Geolocation & finding that when on a device, it fires intermittently and not in conjunction with the frequency value that has been set. Here is my code:

Code:

        var successFn = function(position) {                
                log(position);
        };
        var failFn = function(error) {
            log('Error: ');
            log(error);
        };
Ext.device.Geolocation.watchPosition({
            frequency: 5000, 
            allowHighAccuracy:true,
            callback: successFn,
            failure: failFn
        });

On the device the position only gets logged about 3 times in 10 minutes & the fail function never fires. Has anyone else experienced this?
