826845 - techtudo.com.br doesn't recognize B2G UA as mobile

Status: RESOLVED FIXED

(Web Compatibility :: Site Reports, defect)

Description

[Lawrence Mandel [:lmandel] (use needinfo)]

techtudo.com.br serves a desktop site to B2G. Bug 819210 added an UA override for this domain. The override should be removed once the domain serves mobile content to B2G. This bug tracks the evangelism for the site to recognize the B2G UA and the removal of the override at that time.

I've contacted them (cc-ed Lawrence) and they told me they've fixed it. Now it should just be a matter of time until the fix hits production.

Awesome. Do we know the ETA on when the fix will hit production? Once it hits production, then we can remove the UA override and close this bug.

I asked about an ETA via e-mail.

I've tested on a FXOS Geeksphone dev preview and it's working fine.
It's opening the m. version.

[Jason Smith [:jsmith]]

Confirmed. I'll file a UA override bug for this.

Thanks for letting everyone know!

I still get desktop content after removing the UA override on my Unagi.

Jason - How did you confirm this fix?

The following JavaScript is in charge of the identification of the user agent string and redirect to a different domain name, starting with m.
http://s.glbimg.com/po/tt/m/tectudo/js/glb.behavior.redirectToMobile.js

> 'matcherMobile': /android.*mobile|blackberry|docomo|fennec|htc|ip(?:hone|od)|lge|mot|netfront|nokia|opera\sm(?:ini|obi)|samsung-gt-s8500|skyfire|up\.browser|vx10000|wap|windows\s(?:ce|mobile\s7|phone\sos\s7)/i,

As usual matching "android mobile" "opera mobi" "windows mobile" but not "mobile" alone. They could simplify by adding mobile in the list of strings they are matching. They have an anti-matcher already for tablet.

looks similar to the js from bug 826335 - might be using same backend or lib as globo.com ?

Techtudo is still desktop on mobile. Through Mike we had a contact on September 18, I will try to contact again.

[Leo Balter]

Hello, I contacted 2 friends from Globo.com Andre Fonseca and Davidson Fellipe. They are web developers and maybe can help us on this.

Comment 23

[Karl Dubost💡 :karlcow]

As a reminder, we really need to solve this one, because it's just bad sniffing. The site is working perfectly on Firefox Android, so it will work the same on Firefox OS.

Comment 24

[Karl Dubost💡 :karlcow]

Contacted another person on Globo team. We will see.

[Karl Dubost💡 :karlcow]

And this is fixed! \o/ 
Thanks a lot to Techtudo Globo people.
