If your Xiaomi 15's camera app is crashing, freezing, or just showing a black screen, the first thing to try is a simple restart. Press and hold the power button for about 15 seconds until you feel the phone vibrate and the screen goes black. This force restart clears temporary glitches in HyperOS 2 that can lock up the camera hardware.
Key Points
- Restart and Update Your Phone: A force restart is the fastest way to clear a temporary camera lock-up.
- Clear the Camera App's Data: Corrupted app data is a common cause of crashes and black screens on the Xiaomi 15.
- Check for App and System Conflicts: A third-party app might be interfering with the camera's operation.
- Inspect Camera Hardware and Sensors: A simple smudge on the lens or a blocked sensor can cause major issues.
- Reset App Preferences or Perform a Factory Reset: As a last resort, resetting system settings can resolve deep software conflicts.
Give the phone a full minute to reboot completely before opening the camera app again. I've seen this fix work for most random camera freezes that pop up out of nowhere.
If the problem started after a recent update, check for another one. HyperOS 2 has had some patches specifically for UI and camera stability. Go to Settings > About phone > HyperOS version and tap "Check for updates." Install any available updates and restart your phone afterward.
Clear the Camera App's Data
When the camera app crashes on launch or shows error messages, the app's stored data is often corrupted. Clearing it resets the app to its default state without deleting your photos. Go to Settings > Apps > Manage apps.
Find and tap on "Camera" in your app list. Then, go to Storage usage and tap Clear data. Confirm your choice. This will erase the app's cache and settings, so you'll need to reconfigure any custom modes or shortcuts next time you open it.
After clearing the data, force close the app by swiping it away from your recent apps screen, then open it fresh. This process takes about 30 seconds and fixes a lot of stubborn camera issues on the Xiaomi 15.
Check for App and System Conflicts
Sometimes another app is hogging the camera hardware, preventing the main camera app from working. Think about any apps you recently installed that use the camera, like social media, QR scanners, or banking apps. Try uninstalling the most recent ones to see if the problem goes away.
You can also boot into Safe Mode to check. Press and hold the power button until the power menu appears, then long-press the "Power off" option. Tap "OK" to reboot into Safe Mode. If the camera works perfectly here, a third-party app is definitely the cause.
While you're checking, make sure your camera app itself is updated. Open the Google Play Store, search for "Xiaomi Camera," and see if an update is available. Developers release compatibility fixes for new Android and HyperOS versions all the time.
Inspect Camera Hardware and Sensors
It sounds obvious, but give the camera lens a good wipe with a microfiber cloth. Fingerprints and smudges can cause blurry photos and make the camera software act erratically. Check all the lenses on the back, including the ultrawide and telephoto sensors.
Also, take a look at the front-facing camera cutout at the top of the screen. If you use a screen protector, ensure it's perfectly aligned and not covering any part of the front camera or its surrounding sensors. A misaligned protector can trick the phone into thinking the camera is blocked.
Finally, gently tap the back of the phone near the camera module. Listen for any loose rattling sounds. While unlikely on a new phone, a physically disconnected camera module would cause a complete failure and would require a repair.
Reset App Preferences or Perform a Factory Reset
If you've tried everything else, resetting all your app preferences can help. This won't delete your personal data, but it will reset notification permissions, default apps, and background restrictions. Go to Settings > Apps > Reset app preferences and confirm.
After the reset, you'll need to re-grant permissions the next time you open apps. Test your camera immediately afterward. This fixes issues where a system-wide permission setting got corrupted.
As an absolute last resort, back up all your important data and perform a factory reset. Before you do, use Xiaomi's built-in backup tool or sync your photos and files to Mi Cloud or Google Drive. A clean install of HyperOS 2 can eliminate any deep-seated software conflicts causing the camera to fail.
