Same device as Mobile / Tablet #1588

Closed Ivan-N-Kravchenko closed 1 day ago

Ivan-N-Kravchenko commented 1 month ago

There are different deviceclass values for very similar user agent strings (apparently from the same user / device):

The exact useragent useragent1: 'Mozilla/5.0 (Linux; Android 14; SM-F946N Build/UP1A.231005.007; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/126.0.6478.135 Mobile Safari/537.36 PS_AOS' useragent2: 'Mozilla/5.0 (Linux; Android 14; SM-F946N Build/UP1A.231005.007; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/126.0.6478.135 Safari/537.36 PS_AOS'

Expected/Incorrect fields deviceclass1: 'Phone' deviceclass2: 'Tablet'

Expected behavior I see the difference (Mobile Safari vs. Safari), still not sure how the deviceclass can differ given it's the same Samsung SM-F946N.

I suspect this one to be a Samsung DEX example. Normally a phone but when you connect it to a PC screen it switches to Desktop EXperience which is reported as a tablet.

Thanks for the comment. Indeed such cases seem to be about Samsung devices, I can provide more examples if needed. All in all, does the current behavior appear to be correct? Different deviceclass values for the same device still seem to be confusing.

nielsbasjes commented 1 month ago

Yes, I consider these to be correct. The device is essentially asking for content suitable for phone/tablet class screens. See also https://yauaa.basjes.nl/expect/limitations/#unexpected-differences

And please provide examples you have. If you know for certain what real device it is, then I would like to know that too.

As requested, here are some examples (again, all in know about a real device comes from a user-agent string):

Still it apparently isn't Samsung-specific:
