Why don't background-images work for divs?

Question

css

Made a layout. Everything works in all browsers.
There are several blocks to which image loading is implemented not through IMG, but as background-image.
Today I received a message from a client that on a Samsung p7500 tablet (Android 4.0) images are not loading, but background-color works (as a fallback in case of failure to load).
I do not understand how to approach to understand what the problem is and how to solve it? Thanks

Answer 1

Since you didn’t provide any code or a link to the site, we’ll talk about spherical CSS in a vacuum:

CSS 2.1 properties (well-supported subset): background-image
These properties are supported in effectively all browsers (since IE6+, Firefox 2+, Chrome 1+ etc)
Includes the following:
...
background-image
...

Most likely the problem is something else. But there are no fortune-tellers here - look for a device with a problem and debug it.

Answer 2

options
1. the client did not update the browser cache and the image did not load
2. the image is overwritten by some style from mobile styles
