galaxy S3.. viewport meta tag doesns't work

问题

I'm currently working on the web app which use medium-dpi in viewport meta tag like the below.

<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0,
      width=device-width, user-scalable=no, target-densitydpi=medium-dpi" />

When I test it on a galaxy S3 device, viewport seems not work correctly.

I saw this kind of thing in Android 4.0.2. In android 4.0.2, i heard android OS itself has bug that can't apply the viewport correctly.

Anybody has any idea??

回答1:

I actually found an important clue.

http://developer.android.com/guide/webapps/targeting.html

" values less than (or equal to) 320 result in a value equal to the device-width "

So, Doing "Width=320", a typical setting it migrating from the IPhone, it does not seem to work.

Set it to 321, and it works!

Tested on galaxy s3, playbook, galaxy note
