$dd->getDeviceName() empty

[jcerdan]

Hello,

sometimes $dd->getDeviceName() returns an empty string.
DD detects it's not a bot, but device is empty.

What does that mean? Is it for real a human interaction?

I got the HTTP_USER_AGENT for one of those:

Mozilla/5.0 (iPhone; CPU iPhone OS 17_6_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/21G93 [FBAN/FBIOS;FBAV/479.1.0.33.109;FBBV/637241220;FBDV/iPhone15,2;FBMD/iPhone;FBSN/iOS;FBSV/17.6.1;FBSS/3;FBID/phone;FBLC/es_ES;FBOP/5;FBRV/639094949;IABMV/1]

Looks like FB app running on an iPhone...

regards

HI @jcerdan! This is indeed the Facebook app running on iPhone 14 Pro, and is a human interaction.

In this case, device should have been a phablet. I think you are running an outdated version of Matomo or device-detector. Detection is working as expected:

Hi @liviuconcioiu ,

I'm running version 6.4.0.
I have tested the user agent there:
https://devicedetector.lw1.at

and I get

{
  "isBot": false,
  "clientInfo": {
    "type": "mobile app",
    "name": "Facebook",
    "version": "479.1.0.33.109"

How do you get the info for device=phablet?

There's a bug on the website (user agent is wrongly encoded), reported in Findus23/devicedetector.net#4.

If you use the php code, detection works.

<?php

include_once 'path/to/spyc/Spyc.php';
include_once 'path/to/device-detector/autoload.php';

use DeviceDetector\ClientHints;
use DeviceDetector\DeviceDetector;
use DeviceDetector\Parser\Device\AbstractDeviceParser;

AbstractDeviceParser::setVersionTruncation(AbstractDeviceParser::VERSION_TRUNCATION_NONE);

$userAgent = 'Mozilla/5.0 (iPhone; CPU iPhone OS 17_6_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/21G93 [FBAN/FBIOS;FBAV/479.1.0.33.109;FBBV/637241220;FBDV/iPhone15,2;FBMD/iPhone;FBSN/iOS;FBSV/17.6.1;FBSS/3;FBID/phone;FBLC/es_ES;FBOP/5;FBRV/639094949;IABMV/1]';

$result = DeviceDetector::getInfoFromUserAgent($userAgent);

echo Spyc::YAMLDump($result, 2, 0);

I have checked commits. Looks like iOS improvement detection has been added after 6.4.0 release.
I'll try to get package until last commit and see if that solves the problem.
Thanks @liviuconcioiu

Hi,
I have detected that $dd->getDevice() returns null if Client Hints are passed to DeviceDetector.

So this code returns a null value:

$clientHints = ClientHints::factory($_SERVER);
$dd = new DeviceDetector($userAgent, $clientHints);
$dd->discardBotInformation();
$dd->parse();
dump($dd->getDevice());

while the same without ClientHints return the correct device name.

Is that a bug?

[liviuconcioiu]

Is that a bug?

Yes, it is a bug. It was introduced in #7807.

@sanchezzzhak can you look again at the code when you have time?

<?php

include_once 'path/to/spyc/Spyc.php';
include_once 'path/to/device-detector/autoload.php';

use DeviceDetector\ClientHints;
use DeviceDetector\DeviceDetector;
use DeviceDetector\Parser\Device\AbstractDeviceParser;

AbstractDeviceParser::setVersionTruncation(AbstractDeviceParser::VERSION_TRUNCATION_NONE);

$userAgent = 'Mozilla/5.0 (iPhone; CPU iPhone OS 17_6_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/21G93 [FBAN/FBIOS;FBAV/479.1.0.33.109;FBBV/637241220;FBDV/iPhone15,2;FBMD/iPhone;FBSN/iOS;FBSV/17.6.1;FBSS/3;FBID/phone;FBLC/es_ES;FBOP/5;FBRV/639094949;IABMV/1]';

$clientHints = ClientHints::factory([]);
$result = DeviceDetector::getInfoFromUserAgent($userAgent, $clientHints);

echo Spyc::YAMLDump($result, 2, 0);

This test should return

@jcerdan you can check with my change, if you need it working right away, until the commit is merged.

Also, fyi you need to request the headers from browser like this, if you want to fully benefit from client hints detection. Some browsers don't send full headers, if aren't requsted.

<?php

header('Accept-CH: Sec-CH-UA, Sec-CH-UA-Mobile, Sec-CH-UA-Platform, Sec-CH-UA-Platform-Version, Sec-CH-UA-Full-Version, Sec-CH-UA-Full-Version-List, Sec-CH-UA-Arch, Sec-CH-UA-Model, Sec-CH-UA-Form-Factors, Sec-CH-UA-Bitness, Sec-CH-UA-WoW64');

...code...
