But don’t worry, in this guide, we will address this issue and provide six solutions to fix it.

After both devices have restarted, connect your Galaxy Z Flip 4 to your WiFi network again.

Fix 02: Turn Off WiFi Power Saving Option

On the latest Android operating systems, there is a feature called “WiFi power saving”. This feature reduces the power consumption of your Galaxy Z Flip when the WiFi is turned on.

However, this feature has drawbacks because it sometimes causes the WiFi connection to drop frequently, especially when the device is in standby mode.

To disable this feature, follow the steps below:

  1. Open the Settings app on your Samsung Z Flip.
  2. Scroll down and tap on Connections.
  1. Tap on WiFi.

Here’s how you can do it:

  1. Open the Settings app on your Galaxy Z Flip.
  2. Tap on Connections.
  1. Tap on WiFi.

Fix 04: Reset WiFi Router

Resetting your WiFi router helps to fix persistent software glitches that exist in the router’s firmware, causing the connection to drop. This process will wipe all the current settings and restore the router to its factory defaults.

Here are the steps to reset your WiFi router:

  1. Locate the reset button on your router. It’s usually a small hole marked “Reset” on the back or underside of the router.
  2. Use a paperclip or a similar object to press and hold the reset button for about 10-15 seconds.
  3. Release the button once the router’s lights start flashing. This indicates that the reset process has started.
  4. Wait for the router to restart. This process may take a few minutes. Once the router’s lights stop flashing and remain steady, the reset is complete.
  5. Reconnect your Galaxy Z Flip to the WiFi network using the default network name and password. You can usually find these details on a sticker on the router.

Fix 05: Reset Network Settings

WiFi connections on your Samsung Galaxy Z Flip 4 are managed by the network settings. If your device keeps dropping the WiFi connection, there could be misconfigurations or glitches within these settings. 

Resetting the network settings will rule out these issues and ensure a stable WiFi connection.

Here’s how you can reset network settings on your Galaxy Z Flip 4:

  1. Open the Settings app on your device.
  2. Scroll down and tap on General Management.

  1. You will be prompted to enter your device’s PIN, password, or pattern for security purposes.
  2. After entering the required details, tap on Reset.

Fix 06: Connect Your Z Flip 4 to a Different WiFi Router

If your Samsung Galaxy Z Flip 4 continues to drop the WiFi connection even after trying all the above fixes, it’s time to connect your device to a different WiFi router. This will help you determine if the issue is with your WiFi router or your Galaxy Z Flip 4.

Here’s how to do it:

  1. Turn on WiFi on your Samsung Z Flip and look for available networks.
WiFi settings
  1. Select a different WiFi network from the list (you may need the WiFi password if it’s a secured network).
enter wifi password and connect
  1. Connect to the new WiFi network and monitor the connection.

If your Galaxy Z Flip 4 maintains a stable connection to the new WiFi network without dropping, it suggests that the problem lies with your original WiFi router. In this case, you need to contact your internet service provider or take your router to a repair center for a check-up.

However, if your device still drops the WiFi connection with the new router, it’s likely that the problem is with your Samsung Galaxy Z Flip 4. In this case, you need to contact Samsung support or take your phone to a Samsung service center for further assistance.
