Most mobile phones are used by Internet hot spot, but found a browser with Google, from time to time untapped page. DNS finally found the problem, the original is my dns 8.8.8.8.
The last change to Ali's DNS 233.5.5.5 /233.6..6.6, open the page more fluent.
In the dialog box, select the dns default is automatic, you can change the settings on the page, dns can be modified!
