If your POCO X7 Pro camera is showing a black screen, start with a simple restart. Press and hold the power button until the shutdown menu appears, then tap Restart. I've seen this fix work for most temporary software glitches that cause the camera app to freeze or not initialize properly.
Key Points
- Restart Your Phone: This clears temporary app data and can fix the camera's black screen.
- Check for App Updates: An outdated camera app can cause compatibility issues.
- Clear the Camera App's Cache: Corrupted temporary data is a common culprit.
- Check App Permissions: The camera needs permission to access your phone's hardware.
- Boot in Safe Mode: This helps determine if a third-party app is interfering.
- Update Your System Software: HyperOS updates often include camera stability fixes.
- Reset App Preferences: This resets all app permissions and defaults without deleting data.
- Try a Third-Party Camera App: This tests if the problem is with the stock app or the hardware.
- Perform a Factory Reset: A last resort to clear deep system corruption.
Give the phone a full minute to reboot completely before opening the camera app again. Sometimes the system needs a moment to reload all the necessary drivers.
Check for App and System Updates
An outdated camera app can easily cause a black screen due to bugs or compatibility issues with newer system software. Open the Google Play Store, tap your profile icon, and go to Manage apps & device > Updates available. Look for the POCO Camera app or any system camera updates and install them.
Next, check for a full system update. HyperOS 2 on the X7 Pro receives regular patches that fix known issues. Go to Settings > About phone > HyperOS version and tap "Check for updates." Install any available update and restart your phone afterward.
Clear the Camera App's Cache and Data
Corrupted temporary files, known as cache, are a frequent cause of the black screen problem. Clearing this data forces the app to start fresh. Go to Settings > Apps > Manage apps.
Find and tap on "Camera" in your app list. Then, go to Storage usage and tap Clear cache. Try the camera again. If the black screen persists, you can go back and tap Clear data. Just be aware this will reset all your camera settings to default.
Verify Camera Permissions
The camera app needs explicit permission to access your phone's camera hardware. If this was accidentally revoked, you'll just see a black screen. Open Settings > Apps > Manage apps and select the Camera app again.
Tap on Permissions. Make sure the "Camera" permission is set to "Allow." While you're there, also check the "Microphone" permission if you plan to record video.
Boot Into Safe Mode
If a recently installed third-party app is conflicting with the camera, Safe Mode will tell you. Press and hold the power button until the power menu appears. Then, press and hold the "Power off" option on your screen.
A prompt will appear asking if you want to reboot to Safe Mode. Tap OK. If the camera works perfectly in Safe Mode, you know a downloaded app is the problem. Start uninstalling your most recent apps one by one until the camera starts working again in normal mode.
Reset All App Preferences
This is a useful middle step before a factory reset. It resets all app permissions, default apps, and background restrictions without deleting any of your personal data or apps. Go to Settings > Apps > Manage apps.
Tap the three-dot menu in the top right and select Reset app preferences. Confirm the action. After your phone resets, you'll need to re-grant permissions when you open apps for the first time, but it often resolves conflicts causing hardware access issues.
Test With a Different Camera App
Download a free third-party camera app like Open Camera or Google Camera from the Play Store. Open the new app and see if it can display a live view. If the third-party app also shows a black screen, the issue is likely deeper within the phone's system or could be a hardware problem.
If the new app works perfectly, then the problem is isolated to your stock POCO Camera app. In that case, after trying the other fixes, you could consider using the third-party app as a workaround.
Perform a Factory Reset
If none of the software fixes work, a factory reset is the final step to rule out deep system corruption. This will erase all data on your phone, so it's crucial to back up everything important first. Use Xiaomi's cloud backup or transfer files to a computer.
Once backed up, go to Settings > About phone > Factory reset. Follow the prompts to erase all data. After the phone restores itself, set it up as new without restoring a backup immediately to test if the camera works on a clean system.
