What to do if Galaxy S10 5G internet is slow | 5G connection is slow or not working

If you have a Galaxy S10 5G but cellular connection speed is not what you expect, there may be a problem. 5G connection speeds are obviously way faster than the current 4G speeds at this time so you definitely have the right to question. This troubleshooting guide will walk you through the steps if your Galaxy S10 5G internet is slow.

S10 5G internet is slow fix #1: Confirm 5G is working

Being the only 5G capable phone in Samsung’s lineup today, the first thing that you want to do is to ensure that your phone is set to use 5G properly. This means checking if the right network mode is enabled on the device. To do this, follow the steps below:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile networks.
  4. Tap Network mode.
  5. Select 5G in the list. Make sure that there’s a check mark beside it.
  6. Check for the problem.

If your S10 5G internet is slow even when 5G network mode has already been selected, make sure that it’s not a network problem by checking if there’s a 5G indicator showing up at the status bar. If it only shows 4G or slower network, it’s possible that 5G signal in your current location is problematic. Check with your carrier if your place has 5G coverage. Keep in mind that 5G is new technology may not be available in places where 4G is working. Again, get first hand information from your network operator about this.

S10 5G internet is slow fix #2: Check signal strength

If your Galaxy S10 5G shows it’s connected to a 5G network but the signal strength is low (has 1 or 2 signal bars only), this may be the reason why internet is slow. Try to run a speed test and check the speed you’re getting. You can install Ookla’s speedtest app to do this task. Depending on your carrier, the speed may vary. If you were able to get faster 5G connection in the same place you’re currently at before, it’s possible that there may be a device or network issue that causes the problem. Try to call your network operator first and see if they’re experiencing 5G connection problems in the area. Otherwise, continue troubleshooting your device by following our suggestions below.

S10 5G internet is slow fix #3: Restart device

One of the effective ways to fix network problems is to simply restart the system. Temporary bugs may develop after your phone is left running for some time. To see if that’s the case, try to press and hold the Power button. From there, tap the Restart option to reboot. Or, you can press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your S10 using this method at least once a week to lessen the chances of bugs.

For some Galaxy S10, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

S10 5G internet is slow fix #4: Reset network settings

Since the main problem is internet connectivity being slow, the next move for you is to ensure that the device has proper network configuration. You can do that by resetting the phone’s network settings. This is usually effective in fixing connection problems. Here’s how to do it:

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

S10 5G internet is slow fix #5: Refresh the system cache

Android depends on a set of temporary files called system cache to load apps quickly. If this cache gets corrupted or outdated, a device may suddenly lag, freeze, or show signs of slow performance. At other times, uncommon glitches may occur as well as overall performance of the system may also be affected. To ensure that your S10 has good system cache, we suggest that you clear it once every few months. Here’s how to do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

S10 5G internet is slow fix #6: Turn off downloads

With some Galaxy S10 5G users reporting download speeds of over 1Gbps, downloading large files is obviously a breeze. In case you forget, make sure that your device is not downloading anything at this time. Apps that manages downloads like torrent apps can run in the background and continue to download. Try to go over your list of apps and see if it’s possible that any one of them may be downloading something.

S10 5G internet is slow fix #7: Check for bad third party app

Sometimes, a poorly coded app or malware may interfere with Android and cause problems. To check if you have a third party app problem, restart the phone to safe mode. On safe mode, all third party apps, the ones you downloaded that did not come with the original software, will be suspended. So, if the problem comes from one of them, the problem you’re experiencing right now will not be available on safe mode. To boot the phone to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

If your Galaxy S10 5G internet connection speed improves significantly on safe mode and you think that you have an app problem, you should investigate further. To identify the culprit, you can use the method of elimination. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 is still problematic, repeat steps 1-4.

If your Galaxy S10 5G internet is still slow at this point, the final troubleshooting step that you can perform on your device is factory reset. This will ensure that you return all software settings to their defaults. Make sure to create a backup of your personal data ahead of time to avoid losing them.
