Cordova css properties not working same in all devices

Question

I am using ionic framework to build my next app. I am trying to set a background svg image to body, in desktop browsers(firefox & chrome) it is perfect, on my nexus 4 the background image is perfect, but when I tried in my friends device i.e. Xiaomi Redmi, the background image position is not proper, it shows some gap from top and bottom.

Here is the screenshot of nexus:

Screenshot of xiaomi:

As you can see that background position is not starting from top. When I checked in another device .i.e Alcatel, the gap still remains but this time it is bigger. In motorola g and samsung galaxy S5, image is perfect.

This is the CSS code applied to body:

body {
    background-image: url("../img/bg.svg") !important;
    background-repeat:no-repeat !important;
    background-position:0 0 !important;
    height:100vh !important;
    width:100% !important;
    background-size:100% 100% !important;
    padding:0 !important;
    margin:0 !important;
    position:relative !important;
    background-attachment:fixed !important;
}

Here is my SVG file

Answer 1

As Wayferer mentions, this is most likely a difference in rendering between the two Android versions (KitKat and Lollipop).

There are a couple ways to address the issue:

1. Give all your Android installations the same browser version by using the Crosswalk plugin. Crosswalk swaps out the WebView with the latest Chromium browser so that all Android v. > 4.0 devices will see the same thing. The downsides are that:

   • You won't be able to support Android < 4.0
   • You won't be able to build on PhoneGap build yet (they do plan support, eventually)
   • The download size for your app gets bigger, due to the embedded browser

2. If you'd rather track down the difference and resolve it without Crosswalk, you can take a look at caniuse.com (http://caniuse.com/#feat=svg-css) to see if there's any obvious issue with the HTML / CSS classes you're using. You can also try remote debugging into the older device (instructions: https://developer.chrome.com/devtools/docs/remote-debugging), to see what the elements are that are causing the problem.
