How to Fix Black Camera Screen on Xiaomi, POCO & Realme Phones (2026 Guide)

on

Black camera screen fix is one of the most searched Android problems right now, especially among Xiaomi, POCO, and Realme users. Many users suddenly open the camera app and only see a black screen, frozen preview, or camera crash message. In some cases, the front camera stops working while the rear camera works normally. For others, the camera app keeps closing after a software update.

If you are facing this issue, don’t panic. In most situations, this problem is caused by software bugs, corrupted cache files, overheating, or permission conflicts — not hardware damage. The good news is that you can fix the camera black screen issue in just a few minutes without visiting a service center.

In this guide, we will explain the best working methods to fix camera problems on Xiaomi, POCO, and Realme phones in 2026. These methods work on HyperOS, MIUI, Realme UI, and most Android versions.

1. Restart Your Xiaomi, POCO, or Realme Phone

The easiest way to fix a black camera screen is by restarting your phone. Temporary bugs in Android can stop the camera service from working properly.

Simply press and hold the power button and tap Restart. After rebooting, open the camera app again and check if the issue is fixed.

2. Check Camera Permissions Properly

Sometimes the camera app cannot access hardware because camera permissions are disabled.

  1. Open Settings
  2. Go to Apps → Camera
  3. Tap Permissions
  4. Allow Camera, Microphone, and Storage access

This method works especially well for Realme UI and HyperOS devices after software updates.

3. Clear Camera App Cache and Data

Corrupted cache files can cause camera crashes, black screens, or frozen previews.

  1. Go to Settings → Apps
  2. Find Camera App
  3. Tap Storage Usage
  4. Click Clear Cache
  5. Then tap Clear Data

Now reopen the app. In many cases, this instantly fixes the problem.

4. Close Background Apps and Reduce Heating

If your phone overheats during gaming or video recording, the camera may stop functioning temporarily.

Close heavy apps running in the background and let the phone cool down for a few minutes. Avoid using the camera while charging.

5. Boot Into Safe Mode

Third-party apps like beauty filters, cloned camera apps, or screen recorders can conflict with the camera service.

Boot your device into Safe Mode and check whether the camera works normally. If it works, uninstall recently installed apps.

6. Update System Apps and Software

Xiaomi and Realme often release bug-fix updates for camera issues.

Go to Settings → Software Update and install the latest available update.

You should also update apps from the official Google Play Store.

7. Reset Camera Settings

Open the camera app settings and reset everything to default. Wrong camera configurations sometimes break the app after updates.

If nothing works, you may need to perform a factory reset after backing up important data.
