A completely drained battery or a battery-related issue might prevent the screen from turning on when unfolding the Samsung Galaxy Z Flip 4. In such cases, charging the device for a while will fix the problem.

It’s crucial to use a genuine Samsung charger and cable to ensure the right voltage and amperage are provided to your device. Using non-genuine chargers lead to inefficient charging or even damage your smartphone.

Updating the software on your Samsung Galaxy Z Flip 4 effectively solves various issues, including the screen not turning on when unfolded. An update might contain patches that address software glitches or offer display improvements that can resolve your specific issue.

To check for and perform a software update on your Samsung Galaxy Z Flip 4, follow these steps:

  2. Open the ‘Settings’ app on your Galaxy Z Flip 4.
  3. Scroll down and tap on ‘Software update.’
  4. Select ‘Download and install.’ If an update is available, your device will start downloading it.
  5. Upon completion, the phone will prompt you to install the update. Tap ‘Install now.’
  6. The device will restart during the update process. Wait for the installation to be completed.

After updating your device, unfold it and check if the screen turns on now. If the problem persists, move on to the next fix.

Fix 05 – Check the Hinge for Any Visible Damages

The hinge is a pivotal component in the Samsung Galaxy Z Flip 4’s folding mechanism. Any damage or dysfunction in the hinge causes issues with the screen not turning on when unfolded. It’s essential to inspect the hinge for visible damages that are causing the problem.

To check the hinge of your Samsung Galaxy Z Flip 4, follow these steps:

  2. Carefully inspect the hinge for any signs of damage, such as cracks, deformations, or misalignment.
  3. Gently fold and unfold your phone a few times, paying close attention to any unusual noises or resistance.

If you notice any visible damage or abnormalities in the hinge, it’s best to take your device to an authorized Samsung repair center for further inspection and possible repair. If you are eligible for the warranty, remember to take your warranty information with you. However, if the hinge appears to be intact and functioning correctly, proceed to the next fix to address the screen issue.

Fix 06 – Factory Data Reset

If none of the previous fixes have resolved the issue, perform a factory data reset as the final resort. This process restores your Samsung Galaxy Z Flip 4 to its original factory settings, eliminating any software issues that could cause the screen not to turn on when unfolded. However, this process will also erase all your personal data, apps, and settings on the device. Therefore, it’s crucial to create a backup of your important data before proceeding.

To perform a factory data reset on your Samsung Galaxy Z Flip 4, follow these steps:

  1. Make sure to back up all your important data, such as contacts, messages, photos, and files, either to a cloud service like Samsung Cloud or an external storage device.

If you’ve tried all the previous fixes and the screen still doesn’t turn on when unfolding your Samsung Galaxy Z Flip 4, your device will have a hardware issue. Problems related to the display, hinge, or internal components prevent the screen from turning on, and attempting a DIY repair could further damage your device or void its warranty.

In this case, it’s best to take your Galaxy Z Flip 4 to an authorized Samsung repair center. The technicians can accurately diagnose the problem and provide professional repair services. Before visiting the repair center, make sure to check if your device is still under warranty, as repairing the device under warranty can save you repair costs.
