The ‘Cannot connect to camera’ error on Xiaomi phones is frustrating — you open the camera app and get a black screen with that message instead of a viewfinder. The good news is this is almost always a software issue with a handful of reliable fixes.
Short Answer: The fastest fix is to force stop the camera app and clear its cache: Settings → Apps → Camera → Force Stop, then Clear Cache. If that doesn’t work, restart in Safe Mode to check for third-party app conflicts, or check if another app is using the camera in the background.
Fix 1: Force Stop and Clear Camera Cache
- Go to Settings → Apps → Manage apps
- Find and tap Camera
- Tap Force Stop
- Tap Clear data → Clear cache
- Open the Camera app again

Fix 2: Restart the Phone
A simple restart clears any app that may have the camera locked. Hold the power button → Restart. Try the camera app immediately after the phone boots up before opening other apps.
Fix 3: Check Which App is Using the Camera
On MIUI/HyperOS, another app may have the camera locked in the background:
- Pull down the notification shade and look for any active notification from an app using the camera (video call apps, security cameras, etc.)
- Close all recent apps (tap the recent apps button → Close all)
- Try the camera again
On HyperOS (MIUI 14+), go to Settings → Privacy → Permission manager → Camera and check which apps have camera access — revoke it from any suspicious or unnecessary apps.
Fix 4: Boot in Safe Mode
Safe Mode disables all third-party apps. If the camera works in Safe Mode, a third-party app is the cause.
- Hold the Power button → long-press Restart → Safe Mode
- Open Camera in Safe Mode
- If it works, reboot normally and uninstall recently installed apps one by one until the conflict is found

Fix 5: Update MIUI/HyperOS and Camera App
Camera issues on Xiaomi are often fixed in system updates:
- Settings → About phone → MIUI/HyperOS version → Check for updates
- Also update the Camera app via Play Store or GetApps (Xiaomi’s app store)
Fix 6: Reset App Preferences
- Settings → Apps → Manage apps → tap three dots (⋮) → Reset app preferences
- This resets all app permissions and default settings — permissions you’ve previously granted will need to be re-granted
- Try camera again
Warning: If none of the above fixes work and the camera error appears even in Safe Mode after a restart, the issue may be hardware — a physically damaged camera module or loose connection. Take it to a Xiaomi service center for diagnosis.
Quick checklist:
- ✅ Force Stop + Clear Cache on the Camera app (most common fix)
- ✅ Close all background apps — another app may have the camera locked
- ✅ Boot in Safe Mode to test for third-party app conflicts
- ✅ Update MIUI/HyperOS — camera bugs are often patched in updates
- ✅ Reset App Preferences if permissions got corrupted
FAQ
Does this error happen after an update?
Yes — sometimes a MIUI/HyperOS update introduces camera app conflicts. Clear the camera cache first, and if the problem persists, check Xiaomi’s community forums (c.mi.com) for your specific device model — there’s usually a fix thread if it’s a widespread update issue.
The camera works in other apps but not the default Camera app — why?
The default Camera app may have a corrupted settings or cache file. Try clearing app data (not just cache) for the Camera app. Be aware this resets all camera settings (grid, aspect ratio, etc.) to default.
Can third-party camera apps fix this?
Sometimes — Open Camera or Google Camera (if a port is available for your device) may bypass the issue with the stock app. If a third-party camera app works fine, the problem is specifically with Xiaomi’s Camera app rather than the hardware.
