What to do if LTE connection keeps dropping on Galaxy S10 5G | No or weak LTE connection

If you’re having trouble with LTE connection that keeps dropping on your Galaxy S10 5G, you should do some troubleshooting to know what’s causing it. Our troubleshooting steps below should help you with this.

LTE connection keeps dropping fix #1: Check network signal

Checking for network signal should be the first troubleshooting step that you must do. If LTE connection keeps dropping recently, there may be an issue coming from the network side. This is especially important if you did not have any LTE connection problem in the same location previously. If you are new to this location, it’s possible that your device may not be getting good signal due to interference. Try to move in a more open area and observe how LTE connection works for several minutes. If the situation improves, that means that signal is likely interrupted when you’re in a building. However, if there’s no change even when in an open area, that can mean there’s either a problem with your network, or there’s something in the device that causes it. All you want to do now is to check how strong 4G LTE signal is. If signal keeps dropping and don’t go above 2 bars, there may be a problem with your current location. The network service your carrier provides there may be problematic. To check if that’s the case, go an area with known fast LTE connection and see if there’s an improvement.

LTE connection keeps dropping fix #2: Perform soft reset

Sometimes, a user simply needs to restart the device to fix network problems. If you haven’t tried this yet, be sure to do so. What you want to do is called soft reset. This is basically a restart with the aim of clearing the system by simulating the effects of a battery pull. To do that, simply 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 Galaxy S10 5G using this method at least once a week to lessen the chances of bugs.

For some Galaxy S10 5G, 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)

LTE connection keeps dropping fix #3: Reinsert SIM card

Another way to force an S10 5G to detect 4G LTE is by disconnecting its SIM card temporarily. By doing this, the system will re-attempt to put in new network configuration, which can sometimes help in clearing minor bugs. In order to avoid corrupting data, make sure to turn your phone off first before you remove the SIM card. Do the same before the card is re-inserted.

LTE connection keeps dropping fix #4: Clear network settings

In some cases, 4G LTE connection problems are caused by incorrect network configuration. Try to clear the current set of network settings with these steps:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset > Reset network settings.
  3. Tap Reset settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

LTE connection keeps dropping fix #5: Use slower network temporarily

If LTE connection still keeps dropping at this time, try to manually select another network mode and see if that helps. You can either pick a slower network mode like 2G or 3G or, if available, the faster 5G. It may sometime take a user to manually change to 4G LTE in order to fix this problem. If you haven’t tried this yet, follow these steps to manually force the device to use 4G LTE:

  1. Open Settings app.
  2. Tap Connections.
  3. Tap Mobile networks.
  4. Tap Network mode.
  5. Depending on your options, you should select the one that indicates 4G or similar to this: LTE/3G/2G (auto-connect).
  6. Restart the device and check for the problem.

LTE connection keeps dropping fix #6: Refresh system cache

If LTE connection started acting erratically after an update, it’s possible that there might be a problem with the system cache. This is a set of temporary files used by Android 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 5G 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.

LTE connection keeps dropping fix #7: Install carrier updates

From time to time, new network bugs are discovered so carriers will have to release fixes for them. These solutions are sometimes bundled with system updates. In case the cause of the problem is known by your network operator and they’ve already created a fix for them, make sure to install updates. There are usually two types of updates that you can install: app updates and Android or system updates. In some instances, a third type of update may be released by carriers in order to address a unique bug that shows in their system. Whatever update there will be, make sure to install them to fix troubles or to prevent new bugs from developing. Carrier updates released in the same way that Android updates conducted so all you have to do is to allow the installation once it shows up in the status bar.

LTE connection keeps dropping fix #8: Check on Safe Mode

Network problems like the one you’re experiencing may sometimes be due to a bad installed app. If 4G LTE connection keeps dropping after installing a new app, what you can do is to see if deleting that app helps. If you suspect that there may another app causing the problem, you can run the device to safe mode instead. Safe mode won’t allow third party apps to run and only preinstalled (those that originally came with the software) can work. So, your LTE connection issue won’t happen on safe mode, that’s clear indication of a bad app in the system. To boot the device to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. 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 5G is still problematic, repeat steps 1-4.
