In this troubleshooting article, we will show you how to fix Samsung Galaxy weak network issue that goes regularly or intermittently.

What to do for Samsung Galaxy network problem | the signal is weak or intermittent

If your Samsung Galaxy is losing signal and the reason is unclear, there are some things to check. This guide will help you do this.

Samsung Galaxy network issue # 1: relocation

If your Samsung Galaxy is losing signal randomly, the coverage might be poor. This means there are no network issues or any issues with the device. All you have to do is get out of where you are probably right now. 

Do this if you are in a basement or a building with thick, reinforced walls. You would also want to do this if you are in a rural area with poor or intermittent coverage.

Samsung Galaxy network issue # 2: restart device

By design, your Samsung Galaxy device should be able to switch and connect to their own network without any problems. In reality, an error may occur that could prevent this from happening. This sometimes happens if you’re traveling in an area with inconsistent cellular coverage. 

To fix the problem, all you have to do is restart your device. Try rebooting normally by pressing the Power button first to access the boot menu. Next, select the Restart option and see if it works.

Another way to restart the device is to press and hold the Volume Down button and the Bixby / Power key simultaneously for 10 seconds or until the device’s screen turns on. This simulates the effect of removing the battery from the device. 

If rebooting regularly doesn’t work, try this:

  1. Press and hold the Volume Down button first and don’t let go.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more. 

The second reboot procedure tries to simulate the effects of removing the battery pack. In older devices, disconnecting the battery is often an effective way to fix devices that are not responding. If nothing has changed though, move on to the next recommendations.

It can be helpful to regularly reboot your device, at least once a week. If you’re going to forget something, we recommend that you configure your phone to restart on its own. You can schedule this task by following the steps below:

  1. Open the Settings app.
  2. Tap Device Maintenance.
  3. Tap the 3 dots at the top.
  4. Select the Auto reboot option.

Samsung Galaxy network issue # 3: remove SIM card

If your Samsung Galaxy is still losing signal, your next move is to remove the SIM card to refresh the connection. Follow these steps to remove your SIM card from your device.

  1. Turn off your Samsung Galaxy device. This is important. Removing a SIM while the device is powered on may corrupt data.
  2. With your phone screen facing you, remove the card tray. You can use the insert / eject tool (or paperclip) by inserting it into the provided slot to unlock the tray. This small hole should appear on the top of your device.  
  3. Remove the SIM card from the tray. You can lift the card from the bottom up. To help, use the opening on the opposite side of the tray to remove it (using a fingernail or similar tool).
  4. Replace the card tray.
  5. Press the tray down to lock it in place.
  6. So much!

After removing the SIM card from the device, wait a few minutes before inserting it again. This has the effect of refreshing the system without the old cellular settings. After reinserting the SIM card and restarting the phone, your network configuration should be automatically added. 

You can also try inserting the SIM card if you have another phone that can work with your network. This will help you check if there is a problem with the SIM card itself. If the problem is resolved when you use the SIM card on the second device, you have an issue with the SIM or network. Try to get a new SIM card to see if it’s SIM or network.

Samsung Galaxy network issue # 4: reset network settings

One of the basic things you should do in this case is to clear the current network configuration. This usually works for many network issues on Android devices. Make sure you follow these steps:

  1. Open the Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Network settings reset.
  5. Tap Reset settings to confirm.

Samsung Galaxy network issue # 5: install carrier updates

One way to avoid network problems is to let you install system updates as is. If you got your Samsung Galaxy device from your carrier and you have never changed the software, all you have to do is tap the notification in case any updates are available. Network issues specific to your network operator are often fixed with updates. 

Samsung Galaxy network issue # 6: change network mode

Sometimes changing a device’s network mode from 4G LTE to 3G can get rid of network problems. If you haven’t tried doing this from this point on, here are the steps you should follow.

  1. Open the Settings app.
  2. Tap Links.
  3. Tap Mobile networks.
  4. Touch Network mode and choose 3G or 2G.
  5. Restart the device and repeat steps 1-3.
  6. Tap 4G or LTE or auto connect to go back to original configuration.

Samsung Galaxy network issue # 7: disconnect from network

If your Samsung Galaxy is still losing signal at this time, consider temporarily disconnecting from your network operator. Here’s how to do it:

  1. Open the Settings app.
  2. Tap Links.
  3. Tap Mobile networks.
  4. Tap Network operators.
  5. Tap Select manually.
  6. Wait for your device to search for the network.
  7. Once the search is done, choose another network to connect to. 
  8. Your phone will have to come back with an error because it won’t be able to register successfully.
  9. Later, select your own network again and see if your device can re-record and fix the error.

Samsung Galaxy network issue # 8: beware in safe mode

One of the common causes of Android problems is a bad app. Make sure to check if there are any rogue apps on the system by running your Samsung Galaxy device in safe mode.

All third applications, applications that you add on top of the originals that come with the software, are not allowed to run in safe mode. They will all be gray and you won’t be able to use them.

So if your Samsung Galaxy device has a steady signal and the situation improves, it could mean that one of those apps is to blame.

To restart your Samsung Galaxy device in safe mode:

  1. With your device turned on, press and hold the Power button until the Power off menu appears and then release it.
  2. Press and hold Power off until the safe mode prompt appears and then release it.
  3. Tap Safe mode to confirm.
  4. The process may take 30 seconds to complete.
  5. After the reboot, ” Safe mode ” should appear at the bottom left of the home screen .
  6. Check the problem.

Safe Mode can be a useful trick in checking for an issue, but it doesn’t pinpoint the exact application. To determine which of your apps might be behind the problem, you need to do a knockout. Here’s exactly what you need to do:

  1. Boot your Samsung Galaxy to safe mode.
  2. Check the problem.
  3. If the problem returns or after confirming that a third party app is to blame, you can start by uninstalling the apps one by one. If you have a large number of apps installed, you will need to spend some time doing this. We recommend that you start with the most recently added ones. 
  4. It is important that you only uninstall one application at a time. After uninstalling an app, restart the phone to normal mode and check for the problem again.
  5. If your Samsung Galaxy device is still problematic, try 1-4 until the rogue app is identified. Repeat the steps.

Note that there are no shortcuts for knowing which app is bad or buggy. Just be patient and if the problem returns after uninstalling an app, keep repeating the above cycle. Once the problem has stopped, the last app you deleted should be the culprit. Make sure you don’t reinstall the bad app. You can add the rest of the apps you deleted earlier later.

Samsung Galaxy network issue # 9: wipe cache partition

If your Samsung Galaxy device started having problems with this network after installing an update or app, there’s a chance that the problem is caused by a bad system cache. Try clearing the cache partition to make sure the system cache is fresh. This is where the system cache is kept and clearing forces the device to rebuild a new cache.

Here’s how to do this:

  1. Turn off the device. This is important as your device will not boot into Recovery Mode while it is powered on.
  2. Press and hold the Volume Up key and the Bixby / Power key.
  3. When the Android Recovery screen opens, release the buttons.
  4. Use the Volume Down button until you highlight the ‘Wipe cache partition’ option.
  5. Press Power button to select ‘Wipe cache partition’ option.
  6. Use the Volume Down button to highlight Yes.
  7. Press the Power button to confirm the action of clearing the cache.
  8. Wait a second while the system clears the cache.
  9. Press the Power button again to restart the device. This will return the device to its normal interface.
  10. So much!

Samsung Galaxy network issue # 10: factory reset

The last troubleshooting that you can perform on your device at this point is a factory reset. This will help you tell if your Samsung Galaxy device has a unique software bug that prevents network functions from working properly. Make sure to back up your files first to avoid losing them.

There are two ways to restore your Samsung Galaxy device to factory settings:

Method 1: How to hard reset Samsung Galaxy device from Settings Menu

Method 2: Hard reset on Samsung Galaxy using hardware buttons

If your situation is that the phone is not turning on or it is booting but the Settings menu is inaccessible, this method can help. First of all, you need to boot the device into Recovery Mode. Once you’ve successfully accessed the recovery, it’s time to start the proper master reset. You may need to do some experiments before accessing Recovery, so be patient and try again.

  1. If possible, take a backup of your personal data beforehand. If your problem is preventing you from doing this, just skip this step.
  2. Also, you want to make sure you remove your Google account. If your problem is preventing you from doing this, just skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot into Recovery Mode. If you are unable to regularly turn off the device using the Power button, wait until the phone battery is dead. Then charge the phone for 30 minutes before booting into Recovery Mode.
  4. Press and hold the Volume Up key and the Bixby / Power key.
  5. When the green Android logo displays, release both keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

  7. Use the Volume Down button until you are highlighting ‘Wipe data / factory reset’.
  8. Press the Power button to select ‘Wipe data / factory reset’.
  9. Use the Volume Down button to highlight Yes.
  10. Press the Power button to confirm clearing your phone data.

Samsung Galaxy network issue # 11: Repair

Some phones may have factory defects on them. Although rare, there have been instances in the past when Samsung Galaxy devices suffered from hardware issues that caused their network functions to perform poorly. 

If the problem persists after resetting the device’s software to default settings, there may be a deeper cause of the problem. We recommend that you contact Samsung for support. Alternatively, they can report the problem to your carrier so they can check if the cause is network or firmware-related.
