[Fixed] Why Is My Lock Screen Black Android & How to Fix

Part 2: 5 Methods to Fix Black Lock Screen Android

Method 1: Restart Your Phone

One of the quickest and simplest ways to troubleshoot a black lock screen is by restarting your phone. A reboot clears temporary files and refreshes the system, often resolving minor glitches. Here are the steps to fix why is my lock screen dark and blurry:

• Press and hold the power button on your phone until the restart option appears.
• Tap on Restart and wait for your device to reboot.
• Once restarted, check if the black lock screen issue is resolved.

If a simple restart doesn’t work, try a forced reboot. For most Android devices, this can be done by holding down the power button and the volume down button together for about 10 seconds until the device restarts.

Method 2: Software Update

Outdated software can cause various issues, including a black lock screen. Android frequently releases updates to improve system stability and security, so checking for a pending software update might resolve the problem.

• Go to Settings on your Android device.

• Scroll down and select Software Update.


• Tap on Check for updates to see if there’s a new version available.
• If an update is available, download and install it.
• After the update is complete, restart your device and check if the black screen issue is resolved.

Updating your software can resolve bugs, improve performance, and sometimes fix the lock screen display issues.
