Are you tired of seeing a white or black bar at the top of your React Native Expo app on iPhone devices with a notch? You’re not alone! Many developers have struggled with this issue, but don’t worry, we’ve got you covered. In this article, we’ll explore the reasons behind this problem and provide a step-by-step guide on how to fix it.
Understanding the iPhone Notch
The iPhone notch, also known as the “sensor housing,” is a design feature introduced by Apple in 2017. It’s a cutout at the top of the screen that houses the front-facing camera, earpiece, and other sensors. While it’s a clever design innovation, it can pose challenges for app developers, especially when it comes to background images.
The Problem: React Native Expo Background Not Covering iPhone Notch
When you create a React Native Expo app, you might notice that the background image or color doesn’t cover the entire screen, leaving a visible bar at the top of the iPhone screen. This is because Expo, by default, doesn’t account for the notch area when rendering the background.
Solution 1: Using the `safeArea` View
The simplest way to fix this issue is to use the `safeArea` view provided by React Native Expo. This view automatically adjusts its layout to account for the notch area on iPhone devices.
import { SafeAreaView, View, ImageBackground } from 'expo';
const App = () => {
return (
);
};
In this example, we wrap our `ImageBackground` component with the `SafeAreaView` component. This ensures that the background image is rendered within the safe area, avoiding the notch region.
Solution 2: Using the `StatusBar` Component
An alternative approach is to use the `StatusBar` component provided by React Native Expo. By setting the `translucent` property to `true`, we can make the status bar translucent, allowing our background image to cover the entire screen, including the notch area.
import { View, ImageBackground, StatusBar } from 'expo';
const App = () => {
return (
);
};
In this example, we add the `StatusBar` component at the top of our screen and set the `translucent` property to `true`. This allows our background image to cover the entire screen, including the notch area.
Solution 3: Custom CSS Solution
If you’re not using Expo’s `ImageBackground` component, you can use a custom CSS solution to fix the notch issue. By adding a negative margin to the top of your background element, you can make it cover the entire screen, including the notch area.
import { View, Text } from 'react-native';
const App = () => {
return (
);
};
In this example, we add a negative margin of 44 pixels to the top of our background element, which is approximately the height of the notch area on most iPhone devices. This makes the background cover the entire screen, including the notch area.
Additional Tips and Considerations
When working with React Native Expo and iPhone notch devices, keep the following tips and considerations in mind:
- Test on multiple devices: Make sure to test your app on multiple iPhone devices with different notch sizes to ensure your solution works across all devices.
- Use a flexible layout: Use a flexible layout that can adapt to different screen sizes and notch heights.
- Provide alternative designs: Consider providing alternative designs or layouts for devices with notches to ensure the best user experience.
- Keep your app up-to-date: Keep your app up-to-date with the latest React Native Expo versions to ensure you have access to the latest features and bug fixes.
| Device | Notch Height (px) |
|---|---|
| iPhone X | 44 |
| iPhone XS | 44 |
| iPhone 11 | 42 |
| iPhone 11 Pro | 42 |
Remember, the notch height may vary across different iPhone devices. Make sure to test your app on multiple devices to ensure your solution works correctly.
Conclusion

Frequently Asked Question
Got stuck with React Native Expo background not covering iPhone notch? Don’t worry, we’ve got you covered!
Why is my React Native Expo background not covering the iPhone notch?
This issue usually occurs when the `SafeAreaView` component from `react-native-safe-area-context` is not used properly or is missing altogether. Make sure to wrap your app’s content with `SafeAreaView` to ensure that the background covers the notch.
Do I need to add any specific styles to make the background cover the notch?
Yes, you’ll need to add `flex: 1` and `backgroundColor` styles to your main view. This will ensure that the background covers the entire screen, including the notch. For example: `
Will using `SafeAreaView` affect my app’s layout on non-iPhone devices?
No, `SafeAreaView` is designed to work seamlessly across different devices and screen sizes. It will automatically adjust the layout to accommodate the notch on iPhone devices, while leaving the layout intact on other devices.
Can I use a custom background image that covers the notch?
Yes, you can use a custom background image that covers the notch. Just make sure to set the `resizeMode` property of the `Image` component to `cover` or `contain`, depending on your image size and layout requirements.
Are there any other common issues I should watch out for when dealing with iPhone notches?
Yes, be mindful of other common issues like incorrect `SafeAreaView` usage, misconfigured styles, and layout conflicts with other components. Also, make sure to test your app on different iPhone devices and screen sizes to ensure a smooth user experience.
