Why Does Your Z Flip 4 Keep Turning Off?

Before diving into the fixes, it’s essential to understand the possible causes behind your Samsung Galaxy Z Flip 4 turning off unexpectedly. There are 4 reasons for this issue, and identifying the root cause is crucial to choose the appropriate solution. 

Here are 4 causes behind your Z Flip 4 turning off:

  1. Software glitches: Sometimes, minor software bugs cause the device to shut down unexpectedly. Restarting the device often resolves these issues.
  2. Faulty hardware: If there’s a problem with the device’s hardware, such as a defective power button or display, it causes the device to turn off.

  4. Auto Restart feature: The Galaxy Z Flip 4 has an Auto Restart feature that causes the device to restart periodically. If this feature is enabled, you will experience continuous power-offs.

Understanding these possible causes enables troubleshooting your device and applying the appropriate fix. In the following sections, we will explore 7 solutions to address these issues.

Fix 01 – Restart the Device

As we said before, Restarting your Samsung Galaxy Z Flip 4 resolves minor software glitches and bugs that cause the device to turn off unexpectedly.

It’s important to note that a soft restart, such as tapping the power button to turn off the screen, will not be effective in resolving the problem. Instead, completely power off the device and then turn it back on. 

Here’s how to do it:

restart
  1. Press and hold the Power button and the Volume Down button simultaneously for a few seconds.
  2. When the Power menu appears, tap on the “Power off” option.
  3. Wait for the device to shut down completely.
  4. After a few seconds, press and hold the Power button until the Samsung logo appears, indicating that the device is turning back on.

Once your Galaxy Z Flip 4 has restarted, check if the issue persists.

Fix 02 – Remove the Back Cover

Some back covers, especially those with magnets, interfere with the functioning of your Samsung Galaxy Z Flip 4 and trigger unexpected power-offs. 

To determine if your back cover is causing the issue, follow these steps:

  1. Check if you’re using a back cover for your Galaxy Z Flip 4, particularly one with built-in magnets or metal components.
  2. If you are using such a back cover, remove it from your device.
  3. Restart your device following the steps provided in Fix 01.

After removing the back cover and restarting your device, check if the issue has been resolved. If your Galaxy Z Flip 4 continues to turn off unexpectedly, it could be the screen protector causing the issue.

Fix 03 – Remove the Screen Protector

Screen protectors, especially low-quality or poorly installed ones, interfere with the proper functioning of your Samsung Galaxy Z Flip 4 and cause unexpected power-offs. It’s always recommended to use high-quality screen protectors and ensure they are correctly installed to avoid such issues. 

To check if your screen protector is causing the problem, follow these steps:

  1. Examine your Galaxy Z Flip 4 to see if a screen protector is installed.

Fix 04 – Check If the Power Button is Jammed

A jammed power button causes your Samsung Galaxy Z Flip 4 to turn off unexpectedly. Dirt, debris, or physical damage lead to the power button getting stuck, which in turn may trigger the device to shut down. 

To determine if the power button is jammed and causing the issue, follow these steps:

  1. Examine the power button on your Galaxy Z Flip 4 to see if it appears to be stuck or not functioning correctly.
  2. Press the power button gently to check if it’s responding as it should, with a proper clicking sensation.
  3. If the power button seems jammed, try cleaning around it with a soft brush or compressed air to remove any dirt or debris that may be causing the issue.

If cleaning the power button resolves the problem, your device should function normally. Otherwise we have more fixes for you.

Fix 05 – Check If the Auto Restart Feature is Turned On

The Samsung Galaxy Z Flip 4 has an Auto Restart feature that automatically restarts the device at a scheduled time. While this feature is useful for maintaining optimal performance, it causes continuous restarts or power-offs if enabled unintentionally. 

To check if the Auto Restart feature is causing the issue, follow these steps:

  1. Open the “Settings” app on your Galaxy Z Flip 4.
  2. Scroll down and tap on “Device care” or “Battery and device care” (depending on your device’s software version).

Fix 06 – Clear the System Cache

The system cache, also known as the cache partition, stores temporary data that helps your Samsung Galaxy Z Flip 4 run more efficiently. However, over time, the cache becomes cluttered with outdated or corrupted data, causing unexpected power-offs or other performance issues. 

To resolve this, clear the system cache by booting your device into Recovery Mode. Here’s how:

  1. Power off your Galaxy Z Flip 4 using the steps provided in Fix 01.
  2. Press and hold the Power button and the Volume Up button simultaneously.
  3. Release both buttons when the Samsung logo appears, and your device will enter Recovery Mode.
  4. In Recovery Mode, use the Volume buttons to navigate and highlight the “Wipe cache partition” option. Press the Power button to select it.
  5. Confirm the action by selecting “Yes” when prompted.
  6. Once the cache partition is wiped, the device will return to the Recovery Mode menu. Highlight “Reboot system now” using the Volume buttons and press the Power button to select it.

Fix 07 – Take Your Device to a Repair Center

If none of the previous troubleshooting steps have resolved the issue, it’s possible that your Samsung Galaxy Z Flip 4 has a hardware defect, such as a faulty display component. In this case, the best course of action is to take your device to an authorized Samsung repair center for a professional assessment and repair. 

If your Galaxy Z Flip 4 is still under warranty, the repair center will fix the issue free of charge, depending on the terms and conditions of your warranty. It’s crucial to have your device checked by professionals to ensure a proper diagnosis and avoid causing further damage.

Remember to back up your important data before handing over your device for repair, as the repair process may involve a factory reset or replacement of certain components, which results in data loss.
