i am having a ionic 3 angular app and using the background as follows:

**app.scss**

```
ion-content{
    background-image: url('/assets/images/dummy_bg.jpg');
}

```

this works fine when i see it in desktop browser. however, it does not render the background image on the iphone when i deploy it. 

what could be the issue? i have made sure the size for my iphone 7 plus is 1242\*2208

do i need to do something else to get it working?
