List of common problems on Galaxy Z Flip 4 and their solutions

App Optimization Issues

1. Google Maps not working on cover screen (Maps not optimized for the cover screen)

Google Maps not working on cover screen (Maps not optimized for the cover screen)

With dual display smartphones like the Z Flip 4, one should be happy using a navigation app. But that’s not the case with a few users who took Reddit to show their concern about the app optimization issues on the cover screen of the device. Talking of issues with Google Maps navigation on the cover screen, one user mentioned that the navigation point is always below the green box. As a result, the green box obscures the view of the next junction or location you’re headed to. So, if you are facing similar issues on Z Flip 4’s cover screen while using Google Maps, you shouldn’t worry. All the app optimization issues on the cover screen of Galaxy Z Flip 4 will be fixed with an app update.

2. Problem with calls on Z Flip 4 cover screen (with Google Dialer)


Our quest to fix common Galaxy Z Flip 4 problems led us to a video post on Reddit that shows the cover screen starts glitching when a call is received. While analyzing the video, we could see that the device had Google Dialer turned on. The issue here is associated with the dialer app. It is due to the Google Dialer app not being optimized for the cover screen of Galaxy Z Flip 4, which results in this or a similar kind of issue. 

Possible Solutions:

Since you are having a problem with the Google dialer app, we recommend using Samsung’s native dialer app to fix the issue. It seemed to have fixed the problem of many users including the one who posted the video showing the issue. If you want to use the Google Dialer app then we recommend checking for updates frequently to see if the development team has fixed the issue.

Charging issues on Galaxy Z Flip 4

7. Galaxy Z Flip 4 not charging issue


It might sound very weird that some users have reported slow charging on Galaxy Z Flip 4, even with the official Samsung charger. So, if you are among those unlucky users whose Z Flip 4 is not fast charging or not charging at all, please understand it can be due to several hardware and software issues. It is also possible that the charging cable or power brick you are using to charge the Z Flip 4 is faulty. Another reason why your Galaxy Z Flip 4 is charging slowly could be the use of a non-PPS charger (PPS is the charging standard used by Samsung & Pixel devices for fast charging devices). Also, clogged charging ports and chargers with insufficient power contribute to charging problems on Galaxy Z Flip 4. While, some third-party apps keep draining the phone battery while it is charging, resulting in a slow charging experience on Samsung Z Flip 4 5G. 

Possible solutions:

Before we move to the solution to fix Z Flip charging issues, please ensure the following:

  • Make sure you are using a compatible PPS charger for Flip 4
  • Ensure that the charger and the charging cable are not faulty
  • Inspect the charging port (if you find lint, dust, or debris, please remove it using compressed air can or by blowing air)
  • Is your power outlet working fine?

Once you have ticked all the boxes, you can now move to fix the charging issue.  

When you feel that your device is charging at a much slower speed, try restarting it and see if the problem is fixed. If not, you can also try charging your device in Safe Mode to rule out the involvement of any third-party app behind the Z Flip 4 not charging problem.

8. Samsung Z Flip 4 not charging wirelessly


Are you annoyed because your Galaxy Z Flip 4 won’t charge wirelessly?  Do you feel that wireless charging stops on your Z Flip 4 right before it hits 100%? Well, you are not the one. It is a common issue for Android phones that is caused by several reasons. You are likely to face wireless charging issues on Samsung Z Flip 4 if you are using an incompatible wireless charger, or a case that is super-thick. The problem can also cause due by improper placement of the device on a wireless charger. Though wireless charging problems are common across Android devices, you should try out a few things to make sure it doesn’t bother you again. 

Possible solutions:

You can try the following methods to resolve the wireless charging problem on Samsung Galaxy Z Flip 4 5G:

  1. Make sure you are using an efficient wireless charger (preferably a Qi wireless charger).
  2. Always use a protective case compatible with wireless charging.
  3. Don’t forget to align your flip phone perfectly to the wireless charger you are using.
  4. Restart your device and see if it fixes the problem.

If nothing works, we recommend factory resetting your Z Flip 4 to fix the wireless charging issue. 

Here’s how to factory reset your Samsung Galaxy phone:

  1. Head to Settings
  2. Tap on General management
  3. Next, tap on Reset
  4. Then, tap on Factory reset

9. Fingerprint scanner issues on Galaxy Z Flip 4


While researching, we found out that some units of Galaxy Z Flip 4 are offering inconsistent or slow fingerprint unlock experience.


One Reddit user mentioned that the fingerprint scanner is inconsistent and takes a long time to recognize fingers or thumbs. 

Possible solutions: 

If you are facing slow or inconsistent fingerprint issues on Samsung’s last year’s foldable flagship, you can try a few turnarounds to make the fingerprint scanner fast and accurate. 

  1. Delete the previously registered fingerprints from settings and re-register the fingerprints on your new Z Flip 4.
  2. Make sure to register the thumb as the priority because it aligns perfectly when you hold your device with the right hand. For left left-handers, the index finger should do the trick. 
  3. While registering the fingerprint, we recommend picking up your device as you would do in real-life situations. 
  4. Please ensure your fingerprints are moisture free during setting up scans as well as while unlocking the phone. 

By doing this, the inconsistent and slow fingerprint scanner issues should be resolved.

10. Galaxy Z Flip 4 restarting unexpectedly


You’re about to take a picture of your furry friend doing a trick for everyone and your Flip 4 just restarts. How would you react? Frustrating, right? Trust me, it is disappointing. But, you shouldn’t worry a lot as it is just a software bug. And, given Samsung’s track record of pushing software updates, it should be fixed soon. 


However, you can try a few things to confirm whether this is happening due to any third-party apps installed on your phone. 

Possible workaround: 

If your Galaxy Z Flip 4 is restarting frequently, you can try rebooting it in safe mode to see if it happens again.

Here’s how to restart your Samsung Flip 4 in the Safe Mode:

  1. First, press and hold the power button for a few seconds.
  2. Then, hold the Power OFF option until you see “Reboot in Safe Mode.”
  3. Next, press OK. And, your device will restart on Safe Mode.

You can confirm this by spotting ‘Safe Mode’ written at the bottom left of the screen. You might be wondering how it will help fix this issue. To remind you, Android phones only run system apps when it is in Safe Mode. So, if your device doesn’t restart again while you are in Safe Mode, you should understand that a buggy third-party app is causing the problem. You can either choose to disable or uninstall such apps (if you don’t use them regularly).

12. Battery drain issue on Galaxy Z Flip 4


Even though the battery drain issue is a common problem among any Android smartphone, experiencing it on a flagship flip phone is not amusing for anyone. However, it is fixable unless it is caused by a manufacturing defect of a battery. Before we jump to troubleshooting steps, please note that if you just started using the Flip 4, then you need to wait for a few days. This is because the phone learns your user behavior like which apps you use the most and when to optimize the power consumption according to your usage. 

To remind you, the troubleshooting methods we have mentioned in the section below are handy for fixing battery drain issues on any Android smartphone including the Flip 4 & Fold 4.


Possible Solutions:

  1. Before trying anything, restart your device to see if it fixes the overnight battery drain on Galaxy Z Flip 4. A simple restart can fix minor bugs and glitches that could be problematic for your phone’s battery. 
  2. If rebooting didn’t help, you should try lowering the screen brightness. Either, you can enable the adaptive brightness feature on the Galaxy Z Flip 4. Additionally, you can enable Dark mode as the flip phone uses OLED displays, which should take less toll on the battery by displaying a dark theme.  
  3. You might not notice, but social media apps such as Instagram, Facebook, etc. consume a lot of power. Therefore, it is best to cut down the usage or restrict the background activity of such apps to prevent them from draining your battery drain problems on your Galaxy Z Flip 4. You can always check the time spent on each app from the settings of your device. 
  4. Also, you can disable connectivity features like Bluetooth, Location, Wi-Fi, etc. to save battery on the Z Flip 4. Why? These features run in the background searching for signals which ultimately drain the battery of your phone even if you’re not using it.

Overheating issues are a common problem on almost all smartphones. Generally, smartphones get warm while charging. Please note that your device may get hotter than usual if you are using it while charging or playing
