Camera Preview Shows White Screen in APK - Overlay Visible but Camera Not Displayed

I’ve been working on an Ionic project that involves using the Capacitor Camera Preview plugin to take selfies. Everything works fine when I run the app in the browser or on an emulator. However, when I build the APK and run it on a physical device, the camera preview shows a white screen. The overlay elements are visible, but the camera feed is not displayed.

I’ve ensured that the CameraPreviewOptions are correctly set, and I’ve tried adjusting the z-index and background styles as suggested in various forums, but the issue persists. Here are the details of my setup:

Problem Description

  • When running the app on a device using the APK, the camera preview area shows a white screen.
  • The overlay elements (e.g., the frame image) are visible and interactable.
  • The camera feed is not displayed, though the camera appears to function as expected (e.g., taking pictures works).

Assuming you’ve debugged (looked for any errors) on your Android device looking at DevTools via chrome://inspect/#devices and LogCat in Android Studio?

Also, what version of Capacitor and the plugin are you using?

It’s not showing any error log in chrome://inspect/#devices. Clicking the yellow button only takes a snapshot.

Those are the versions that I am using.

 "@capacitor-community/camera-preview": "^6.0.0",
    "@capacitor/android": "5.6.0",
    "@capacitor/app": "5.0.7",
    "@capacitor/browser": "^5.2.0",
    "@capacitor/core": "^6.1.0",
    "@capacitor/haptics": "5.0.7",
    "@capacitor/ios": "5.6.0",
    "@capacitor/keyboard": "5.0.8",
    "@capacitor/share": "^6.0.1",
    "@capacitor/status-bar": "5.0.7",

First, you have mix-matched versions for Capacitor and its plugins. Everything should be on v5 or v6.

Depending on if you are using Capacitor 5 or 6, you also need to use the correct version for @capacitor-community/camera-preview.

Version 6 of this plugin requires Capacitor 6.

If you are using Capacitor 5, use version 5

`I’ve tried to use version 5 of the plugin, but the error persists. So, I updated my Capacitor version, but I’m still getting the error.

Hi everyone,

I wanted to update you on the issue I was facing with the camera preview showing a white screen in the APK. After further investigation and some trial and error, I found the solution.


The problem was caused by using the Camera Preview plugin within a modal. It appears that the plugin does not function correctly when initialized inside a modal. Instead, it needs to be used directly on a page.

If the camera preview shows a white screen in your APK but overlays are visible, it could be due to camera permissions or compatibility issues with the device’s camera hardware. Check permissions in your manifest file and ensure your camera initialization code handles different device configurations correctly. Updating device drivers or testing on different devices may also help identify the issue.
