Initial Troubleshooting Steps

Before you consider more advanced repair options, try these initial troubleshooting steps. These can often resolve simple issues and save you time and effort.

  1. Force Restart: A force restart can often resolve software glitches that cause a black screen. The method for force restarting a Realme 8 5G is usually to press and hold the power button and the volume up button simultaneously for 10-15 seconds. Check your phone's manual for the specific instructions for your model.
  2. Check the Battery: Ensure your phone has sufficient charge. Plug it into a charger and let it charge for at least 30 minutes. If the charging indicator doesn't appear, try a different charger and cable. A faulty charger or cable can prevent your phone from charging.
  3. Inspect for Physical Damage: Carefully examine your phone for any signs of physical damage, such as cracks, dents, or water ingress. If you see any damage, it could be the cause of the black screen. Focus especially on the screen itself, as a cracked display is a common culprit.
  4. Boot into Safe Mode: Safe mode starts your phone with only the essential system apps, disabling any third-party apps. If your phone boots in safe mode, a third-party app is likely causing the issue. The method for booting into safe mode varies depending on the phone model, but it generally involves pressing a combination of buttons during startup. Refer to your phone's manual for specific instructions.
  5. External Display Test: If possible, connect your phone to an external display using a USB-C to HDMI adapter. If the display works on the external screen, the problem is likely with your phone's display panel.
