This shouldn't be moved outside of the if condition. Let's assume the client hints report a Firefox 16, but the useragent is spoofed by some tool and contains Safari 20.18. We would then end up using Firefox 20.18, which is wrong.

And, how can we detect the full version then? Some times, client hints don't provide Sec-CH-UA-Full-Version

In most cases the browser reported in client hints and in user agent should match. In that case the version from user agent will be used. If not I'm not sure if we should simply use the version from useragent.

if you look at this list, they just printed versions for all OS
Sec-CH-UA: '"Chromium";v="98", "Opera";v="82", " Not A;Brand";v="99", "OperaMobile";v="68"'
Sec-CH-UA-Platform: 'Android'
the current tests I am satisfied with the result.
But in the future it will be necessary to come up with something else when useragent is gone.
as an option:
if Mobile OS + opera family get clienthint OperaMobile=68
if Desktop OS + opera family get Opera=82

Is it known that Opera always reports an incorrect version in the client hints? 🤔

From the data I have, everything is incorrect, just for those two browser.

Hm. I'm not sure how we should handle that. If the browsers might freeze the useragent at some point I'm not sure if the version in useragent will be even updated with new releases or if the number can only be fetched through client hints 🤔

Should I close this PR then?

@sanchezzzhak what do you think about that?

The current changes give an accurate result.
but if there is no user agent in the future, this condition will need to be rewritten.

I will try to deal with this PR in the near 1 week (I think it's tedious to update it to the current state every time) |
