Inconsistent device data from same device when detected from browser vs app.

[rolinger]

Both my website and my app report to my server, using the HTTP_USER_AGENT to do device detection. But I am getting very different results.

use fiftyone\pipeline\devicedetection\DeviceDetectionCloud;
use fiftyone\pipeline\core\PipelineBuilder;
use fiftyone\pipeline\core\Logger;
use fiftyone\pipeline\cloudrequestengine\CloudRequestEngine;

function checkDevice() {
  $key = "....." ; // 
  $domains = "mydomain.com" ;
  $cloudRequestEngine = new CloudRequestEngine(array("resourceKey"=>$key,"cloudRequestOrigin"=>$domains));
  $deviceDetection = new DeviceDetectionCloud(array());  
  
  $Pipeline = (new PipelineBuilder())
              ->add($cloudRequestEngine)
              ->add($deviceDetection)
              ->build();
  $FlowData = $Pipeline->createFlowData();
  
  $FlowData->evidence->set("header.user-agent",$_SERVER['HTTP_USER_AGENT']);  
  // Process the FlowData
  $FlowData->process();
  $hwModel = checkProperty($FlowData->device->hardwaremodel) ;
  $hwName =  checkProperty($FlowData->device->hardwarename) ;
  //$hwVendor = checkProperty($FlowData->device->hardwarevendor) ;
  //$hwCarrier = checkProperty($FlowData->device->hardwarecarrier) ;
  return array($hwModel,$hwName) ;
}

function checkProperty($property) {
  if($property->hasValue)  {
    return var_export($property->value, true);
  }
  return var_export($property->noValueMessage, true);
}

Using Chrome, my website device detection reports:

• // $hwModel = 'Generic Android' ;
• // $hwName = array ( 0 => 'Generic Android') ;

But on the same android phone, my app connects to my server and also does a device detection off of HTTP header:

• // $hwModel = "SM-F721U" ;
• // $hwName = array (0 => 'Galaxy Z Flip4') ;

I think its awesome that its getting my actual phone type from my app which is using cordova-plugin-ionic-webview, but I am surprised using the regular Chrome browser returns nothing relevant that I can use.

What is the issue here, why I am getting generic android from Chrome? What else can I do to get a browser hitting my website to report correctly?

As well, I had to edit out the two lines:

  //$hwVendor = checkProperty($FlowData->device->hardwarevendor) ;
  //$hwCarrier = checkProperty($FlowData->device->hardwarecarrier) ;

because it was throwing errors on them, are they no longer supported?
