Tips to Fix Galaxy Z Fold 4/Flip 4 Booting Issue
1. Check your battery percentage
While it may sound stupid, it does happen. If there is a battery drain issue, your Galaxy Z Fold 4/Flip 4 can keep rebooting or restarting.
The first thing you must do is connect it to the charger and start charging it. However, ensure that you keep using the phone (while connected to the charger) to see if the phone is restarting or rebooting. If it doesn’t, continue charging the phone until completely charged.
Now disconnect the charger and use the phone normally. If the issue doesn’t recur, battery drain was a possible issue.
You must fix the battery drain issue. Read this article to find fixes for your Samsung Galaxy Z Fold 4/Z Flip 4’s battery drain problem.
2. Boot up in the Safe Mode
One of the major causes for such reboots is a corrupt application that you have recently installed.
The solution here is to boot your phone into Safe Mode. In the Safe Mode, all apps except the factory-installed apps will be disabled. If the problem is fixed, you will know that a rogue app is causing the problem.
If you remember the last app you installed before this problem started, simply uninstall it to see if the problem is fixed.
In case you don’t remember which app you installed before the problem showed up, uninstall one app at a time and see if the problem is fixed. You can then reinstall the other apps.
To boot into the Safe Mode, follow the steps below:
- Press and hold the power key.
- Wait for the Power Off icon to appear and then tap and hold it.
- Wait for the Safe Mode icon to appear and then tap on it.
Wait for the phone to reboot into Safe Mode. Now use the phone to see if the problem persists.
3. Run a software update
Software bugs can be super annoying, and they can cause a multitude of problems including this continuous reboot. Updating your phone’s software can help to fix these bugs.
To run a software update, follow the steps below:
- Pull down the Quick Access panel by swiping from the top of the cover screen.
- Tap on the Cog or the Gear icon to open the Settings menu.
- Scroll down and locate the option ‘Software update,’ and tap on it.
- Finally, tap on ‘Download and install.’
This method will work only if updates are available. If updates are not available for download, you must wait for the updates to be made available by Samsung.
Assuming that updates are available, and you install them, check whether the phone’s rebooting problem has been resolved or not.
4. Run a hardware test
Don’t panic! You don’t need to be an expert to perform this test. Your phone already has the mechanism. Your phone’s hardware component can be the root cause.
If the hardware test fails, you must take your phone to your nearest service center of Samsung and have it repaired.
Here is how you run a hardware test.
- Open Samsung Members.
- Tap on the ‘Get Help’ option.
- Tap on Start under Diagnostic tap.
- Select all available options.
- Tap on Start and wait for the test to run.
5. Wipe Cache Partition
The cache partition of your Samsung Galaxy Z Fold 4/Flip 4 holds various cache files that help your phone function properly.
However, if these cache files become corrupt, your phone can behave abnormally. Rebooting and restarting continuously is one of those many abnormal behaviors.
Here are the steps you must follow to wipe the cache partition:
- Turn off your phone.
- Press and hold the Volume Up key and then press and hold the Side key.
- The Android logo will appear. This is where you release all keys.
- The phone will show ‘Installing System Update’ for 30-60 seconds. Wait.
- After that, the phone will show Android recovery menu options.
- Use your phone’s Volume Down key (press several times) to highlight the Wipe Cache Partition option.
- Now, press the Power key to complete the selection.
- Use the Volume Down key to highlight ‘Yes’ and then use the power key to complete the selection.
Wait until the cache is cleared and you see the option ‘Reboot system now’ selected by default. Use the power key to complete the selection and reboot your phone.
Now check for the issue. If the issue persists, there is one more thing you can try.
6. Perform a factory reset
Of course, performing a factory reset should be your last option. When you perform this action, all data will be erased. You will have the option of backing up the data first so that you can restore it later. However, that is not recommended. Restoring old data and cache files can lead to the recurrence of the issue.
It is better to delete all data and start fresh. Here are the steps to perform a factory reset:
- Turn off your phone.
- Press and hold the Volume Up key and then press and hold the Side key.
- The Android logo will appear. This is where you release all keys.
- The phone will show ‘Installing System Update’ for 30-60 seconds. Wait.
- After that, the phone will show Android recovery menu options.
- Use the Volume Down key to navigate to Wipe Data/Factory Reset.
- Use the Power key for selecting the option.
- Use the Volume Down to navigate to Factory data reset.
- Use the Power key to select the option.
Now check whether the issue persists or not. If not, you can start installing third-party apps. But if the issue persists, visit Samsung’s service center.
