Reasons for Wifi not working when Galaxy Z Fold 4 is unfold

Foldable Phone Design

One of the main reasons is the unique design of foldable phones like Galaxy Z Fold 4. They incorporate intricate hardware designs to achieve their folding capabilities. This complex structure may inadvertently interfere with the device’s wifi antenna, leading to wifi disruptions when the phone is unfolded.

Interference from Physical Components

Another potential issue lies with interference from physical components. In the unfolded state, the increased surface area and position of certain components in the device could cause interference with the wifi signal.

Software Incompatibility

It’s also possible that the problem is due to software incompatibility. If the software isn’t fully optimized for the foldable design, it may incorrectly interpret the unfolded state, causing wifi disconnection.

Operating System Glitches

Occasionally, operating system glitches can cause intermittent wifi connectivity. This could be due to bugs in the OS or miscommunication between the OS and the device’s hardware when the phone is unfolded.

Router Compatibility issues

Lastly, router compatibility issues may also be at play. Some routers might not be fully compatible with the unique communication requirements of foldable devices, leading to wifi disconnection issues when the Galaxy Z Fold 4 is unfolded.

How to fix Wifi is not working when Galaxy Z Fold 4 is unfold?

Fix 1: Rectify the Wifi not working when Galaxy Z Fold 4 is unfold

Step 1: Update Software

The very first step is to ensure that your Galaxy Z Fold 4 and your wifi router are running the latest software versions. Here’s how to do it:

  1. On your Galaxy Z Fold 4, go to Settings > Software Updates. If there’s an update available, download and install it.
  2. To update your router’s firmware, you typically need to access the router’s settings through a web browser. The process varies by router model, so refer to your router’s manual or online support page for specific instructions.

Step 2: Reset Network Settings

Next, try resetting your phone’s network settings. This clears any possible corrupt or incorrect settings causing wifi disconnection. Here’s how:

  1. Go to Settings > General Management > Reset.
  2. Tap on Reset network settings and confirm the action.
  3. Your phone will restart. After the restart, reconnect to your wifi network.

Remember, this action will erase all your network settings, including saved wifi networks and Bluetooth pairings, so ensure you have these details saved elsewhere.

Step 3: Switch Wifi Frequencies

Your router broadcasts in two frequency bands – 2.4GHz and 5GHz. Sometimes, switching the frequency can resolve wifi issues:

  1. To do this, access your router’s settings (as described in step 1). Look for a setting related to wifi frequency or band.
  2. Try switching the frequency, save the changes, and then check if your Galaxy Z Fold 4 connects to wifi when unfolded.

Fix 2: Troubleshooting the Wifi Router

When experiencing wifi issues with your Galaxy Z Fold 4 when unfolded, it’s essential not to overlook the wifi router. Here’s a detailed guide to troubleshoot your router:

Step 1: Restart the Router

The simplest step is often the most effective. Restart your router by unplugging it, waiting for a minute, then plugging it back in. Wait for the router to fully boot up, then test your device’s wifi connection.

Step 2: Check Router Positioning

Ensure the router is positioned in an open area, free from physical barriers and interference. Objects and electronic devices can disrupt the wifi signal. If the router is near an object or device causing interference, try relocating the router or the object.

Step 3: Change Wifi Channel

Wifi routers can broadcast on several channels. If your current channel is crowded, it can cause connectivity issues. Access your router settings, find the wifi channel option, and select a less crowded channel.

Step 4: Update Router Firmware

Ensure your router is running the latest firmware version. Most modern routers allow you to check and update the firmware through their user interface. Check your router’s manual or online support for specific instructions.

Step 5: Factory Reset Router

As a last resort, if none of the above steps work, consider resetting your router to its factory settings. Remember, this will erase your current settings. To perform a factory reset, look for a small reset button on your router. Hold it down for about 10 seconds. After resetting, you’ll need to reconfigure your router settings.

Fix 3: Clearing Cache and Data

If your Galaxy Z Fold 4 continues to experience Wi-Fi issues when unfolded, another solution to try is clearing the cache and data. This action can resolve any software glitches or conflicts that might be causing the problem.

Step 1: Clear System Cache

  1. Turn off your Galaxy Z Fold 4.
  2. Press and hold the Volume Up and Power buttons together until you see the Samsung logo.
  3. You’ll enter the Android Recovery Mode. Use the Volume keys to navigate and highlight ‘Wipe cache partition’.
  4. Press the Power button to select this option. Confirm the action if prompted.
  5. Once the cache is cleared, select ‘Reboot system now’.

Step 2: Clear Wifi Settings Cache

If clearing the system cache doesn’t work, you can clear the cache and data for your device’s wifi settings:

  1. Go to Settings > Apps > Show system apps.
  2. Find and select ‘Wifi Direct’.
  3. Tap on ‘Storage’ > ‘Clear Cache’ > ‘Clear Data’.

Remember to reconnect to your wifi network and re-enter your password after clearing the data.

Step 3: Safe Mode

If the problem persists, try operating your device in Safe Mode. This mode disables all third-party apps, allowing you to identify if an app is causing the wifi problem:

  1. Turn off your Galaxy Z Fold 4.
  2. Press and hold the Power button until the Samsung logo appears.
  3. Immediately after releasing the Power button, press and hold the Volume Down button until the device finishes restarting.
  4. ‘Safe mode’ will appear at the bottom of your screen. Check your wifi connection in this mode.

If your wifi works well in Safe Mode, a third-party app is likely causing the issue. You can then identify and uninstall the problematic app.

Fix 4: Network settings reset and testing in a different environment

The next approach to resolve the ‘Wifi not working when Galaxy Z Fold 4 is unfold’ issue is a combination of resetting your network settings and testing your device in different environments.

Step 1: Reset Network Settings

Resetting network settings can fix problems related to connectivity:

  1. Go to Settings > General Management > Reset.
  2. Tap on Reset network settings, then Reset settings.
  3. If prompted, enter your PIN, Password, or Pattern.
  4. Finally, tap Reset.

Remember that this action will erase all network settings, including saved wifi networks and Bluetooth pairings.

Step 2: Test Wifi in a Different Environment

Sometimes, environmental factors can influence wifi performance:

  1. Try connecting to a different wifi network. If your device connects successfully, the issue may be with your primary wifi network.
  2. Alternatively, test your device in a different physical location to rule out any environmental interference with the wifi signal.

Step 3: Use Wifi Analyzer

Download a wifi analyzer app from the Play Store. Such an app can provide insights into the strength and quality of the wifi signal in your area:

  1. Install a wifi analyzer app.
  2. Use the app to analyze the wifi signal in your location. If the signal strength is weak, try moving closer to the router or eliminating potential sources of interference.

Step 4: Test with Another Device

To confirm if the issue is with your Galaxy Z Fold 4 or the wifi network, try connecting another device to the same network:

  1. Connect a different device to your wifi network. If the second device also struggles to connect, the issue likely lies with your wifi network, not your Galaxy Z Fold 4.
  2. If the second device connects successfully, reach out to Samsung’s customer support for further assistance with your Galaxy Z Fold 4.
