Layout height doesn't cover the whole page

## 💬 Question

## UI Kitten and Eva version

| Package | Version |
| ----------- | ----------- |
| @eva-design/eva | 2.1.1 |
| @ui-kitten/components | 5.1.2 |

In my application, in the simulator, everything is fine design-wise, but in my actual device, the height of the page is wrong and/or that the page has this gray background.

How can I add a global background to my app or give my layout full height of the device?

You can see the screenshot as an attachment.

Thanks in advance!
