OnePlus Open Incorrectly Identified as Tablet in Chrome

[jehkiT]

Description:

I'm encountering an issue where a OnePlus Open, a foldable phone device, is being incorrectly identified as a tablet in the Chrome browser. This is causing compatibility issues and preventing certain features from functioning properly.

Expected Behavior:

The device should be recognized as a phablet, given its form factor and capabilities.

Actual Behavior:

The device is recognized as a tablet.

The following methods and their JSON outputs confirm the incorrect identification:

$dd = new DeviceDetector($_SERVER['HTTP_USER_AGENT'] ?? "", ClientHints::factory($_SERVER));
$dd->setCache(new PSR6Bridge(new ApcuAdapter()));
$dd->parse();
$hints = $dd->getClientHints();

echo json_encode($dd->getUserAgent(), JSON_UNESCAPED_SLASHES); // prints "Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/128.0.0.0 Safari/537.36"
echo json_encode($dd->isBot(), JSON_UNESCAPED_SLASHES); // prints false
echo json_encode($dd->getClient(), JSON_UNESCAPED_SLASHES); // prints {"type":"browser","name":"Chrome","short_name":"CH","version":"128.0","engine":"Blink","engine_version":"128.0.0.0","family":"Chrome"}
echo json_encode($dd->isPhablet(), JSON_UNESCAPED_SLASHES); // prints false
echo json_encode($dd->isMobile(), JSON_UNESCAPED_SLASHES); // prints true
echo json_encode($dd->isMobileApp(), JSON_UNESCAPED_SLASHES); // prints false
echo json_encode($dd->isTablet(), JSON_UNESCAPED_SLASHES); // prints true
echo json_encode($hints->getApp(), JSON_UNESCAPED_SLASHES); // prints ""
echo json_encode($hints->getModel(), JSON_UNESCAPED_SLASHES); // prints ""
echo json_encode($hints->getArchitecture(), JSON_UNESCAPED_SLASHES); // prints ""
echo json_encode($hints->getBitness(), JSON_UNESCAPED_SLASHES); // prints ""
echo json_encode($hints->getBrandList(), JSON_UNESCAPED_SLASHES); // prints {"Chromium":"128","Not;A=Brand":"24","Google Chrome":"128"}
echo json_encode($hints->getOperatingSystem(), JSON_UNESCAPED_SLASHES); // prints "Android"
echo json_encode($hints->getOperatingSystemVersion(), JSON_UNESCAPED_SLASHES); // prints ""

Request:

I kindly request assistance in resolving this issue. Any suggestions or workarounds would be greatly appreciated.

Can you check on http://devicedetector.net/ if the device is detected correctly? You have to click on Consider Client Hints (JSON or Headers) and Detect.

From what I see, there's no brand/model, and without this information it fallsback to tablet, because of the user-agent.

Unfortunately, I don't have access to a OnePlus Open device myself. This report is based on feedback received from a user of my web service.

To help diagnose the issue further, I've requested the user to visit http://devicedetector.net/ and provide the "raw data" section of the JSON output generated there. Alternatively, a screenshot of that section would also be helpful.

@jehkiT do you request the client hints from browser using header?

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');

If not, then this might be the reason why the detection isn't working.
