Causes Why Galaxy Z Flip 4 Not Turning On

There could be several reasons why your Samsung Galaxy Z Flip 4 is not turning on. The most common cause is usually a drained battery. If your device’s battery is completely discharged, it may not turn on immediately even after you plug it into a power source.

Other potential causes could include:

  1. Software Crash: Sometimes, the device’s operating system may crash, causing the phone to not turn on.
  2. Hardware Damage: If your device has been dropped or exposed to water, it could cause physical damage to the internal components, preventing the device from turning on.
  3. Corrupted System Data: Corrupted system data or software can also prevent your device from booting up.
  4. Outdated Firmware: Sometimes, outdated firmware can cause issues with the device’s startup process, leading to a black screen or not turning on.

This guide will address all these potential causes and provide solutions to them. Let’s start with the first fix.

Fix 01: Charge the Device

One of the first and simplest things to do when your Samsung Galaxy Z Flip 4 doesn’t turn on is to charge the device. This might seem obvious, but sometimes, the battery could be completely drained, causing the device not to turn on.

To do this, plug your device into a power source using the original charger and cable that came with your device. Wait for a few minutes and see if the charging animation is displayed on the screen. This animation is a clear indication that your device is indeed charging.

If the charging animation is displayed, there’s a good chance that you can fix the issue yourself. In this case, leave your device to charge for at least 30 minutes. 

Charge the Device

After charging your device for a while, try to power it up. To do this, press and hold the power button for a few seconds. If your device turns on, then the issue has been resolved. If it still doesn’t turn on, you need to follow up on the next solutions from Fix 02.

However, if the charging animation doesn’t appear, it’s likely that there’s a more serious issue at hand. In such a case, it’s recommended that you take your device to a Samsung authorized repair center.

Fix 02: Boot Into Recovery Mode

In case your Samsung Galaxy Z Flip 4 is still not turning on after a proper charge, your next step should be to boot the device into Recovery Mode. 

Recovery Mode is a special boot option where you can reset your device or clear its cache. It’s a separate partition from the main Android operating system, which comes in handy when you’re facing issues like this with your device.

Here’s how you can boot your Galaxy Z Flip 4 into Recovery Mode:

  1. Press and hold the Power button and the Volume Up button simultaneously.
  2. Once the Samsung logo appears, release both buttons.

  1. After a few seconds, you should see the Recovery Mode menu on your screen.

Once you are in the Recovery Mode, you should clear the system cache. The system cache is temporary data stored by your system to quickly load apps. However, sometimes this data can become corrupted and cause issues. 

So here’s how to clear it:

  1. Use the Volume buttons to navigate through the Recovery Mode menu and highlight the Wipe cache partition.

  1. Press the Power button to select this option.
  2. Confirm your action by selecting ‘Yes’ when prompted.

After rebooting, your device should power up normally. If it still doesn’t, it’s time to move to the next step.

Fix 03: Flash Firmware

Firmware is a type of software that is directly linked to the hardware of your Samsung Galaxy Z Flip 4. It’s the programming that tells your device how to function, from booting up to making calls to browsing the web. 

Flashing firmware, on the other hand, involves installing a new version of this software onto your device.

This process can be a bit technical and is not recommended for those who are unfamiliar with it since incorrectly flashing firmware can lead to more problems, including potentially bricking your device (frozen).

However, if you are comfortable with this process, you can boot your device into Download Mode and flash the official firmware. This could potentially fix the issue if it’s related to the device’s software. Please note that flashing firmware can void your warranty, so proceed with only if your device’s warranty period is over.

To boot your device into Download Mode, follow these steps:

  1. Power off your device: Before you start, ensure that your Samsung Galaxy Z Flip 4 is completely switched off. You can do this by pressing and holding the power button, then selecting the ‘Power off’ option.

  1. Prepare your USB cable: Have your USB cable ready. You will need to connect your device to a computer during this process.
  2. Press the Volume Up and Down buttons: While your device is off, press and hold the Volume Up and Volume Down buttons simultaneously.

Once you’re in Download Mode, you can use a tool like Odin to flash the official firmware. Make sure to download the correct firmware for your specific model of the Samsung Galaxy Z Flip 4.

If you’re not comfortable with this process, or if it doesn’t solve the issue, it’s recommended to take your device to a Samsung-authorized repair center.

Fix 04: Take the Device to a Repair Center

If your Samsung Galaxy Z Flip 4 still refuses to turn on after trying all the previous methods, it’s time to consider professional help. Taking your device to a Samsung-authorized repair center is the safest and most reliable option in this scenario.
