[Problem] Can't disable pinch to zoom stock browser

[brianmoyano]

Hi everyone, i'm making a portfolio for me, in html, css and js using bootstrap.
So, i made it responsive, but i have a problem.

In the head i have this line:

<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,minimum-scale=1,user-scalable=no" />

It's to disable the pinch to zoom in the web. Works perfectly in Google Chrome, but it doesn't in stock browser.

I know that is a known bug in the stock browser, but, is there a way to solve this?
