What to do if Galaxy S10 keeps losing signal | signal keeps dropping or disconnecting

Troubleshooting a network trouble requires a number of steps. If your Galaxy S10 keeps losing signal, follow the steps below to fix it.

S10 keeps losing signal fix #1: Verify network is up and running

If your Galaxy S10 keeps losing signal, or if network services are intermittent, the most likely reason is poor network coverage or network issue. The first thing that you should check then is to confirm if your carrier’s network services are working normally. By that we mean all the things that require their services such as texting, calling, and mobile data should be up and running. If one or all of the services are affected, that can be an indicator that the problem is not coming from your device. There may be an outage or network maintenance being performed that affects the services that have stopped working. If you want to make sure, try calling your network to get first hand information.

S10 keeps losing signal fix #2: Check if signal is intermittent

This is a continuation of the first troubleshooting step but should only be done if you noticed that the signal keeps disconnecting regularly. For example, if you can see that the signal disappears while you’re trying to send a text or during a call (causing the call to be disconnected), the reason for it must be network-related. Check the signal bars on your S10 to see if the strength (signal bars) disappears or changes to 2 bars or 1 bar. If that’s the case, there may be a problem with cell tower broadcasting the signal.

Keep in mind that signal may disappear or network services may become erratic if you’re travelling. Once you reach an area with good coverage, the signal should become strong again.

If the area you’re in has always been covered and provides strong signals ever since, try checking by using another phone. Make sure that the phone you’ll be using is compatible with your network operator’s system. If the signal on the second phone is fine and does not drop, there must be an issue with your S10 and not with the network. In this case, you should continue troubleshooting your device.

S10 keeps losing signal fix #3: Perform a soft reset

If you’ve confirmed that there’s no network problem at all, the next good thing to do is to soft reset your S10. We suggest that you try doing the steps below to fully refresh the system:

  1. Press and hold the Power + Volume Down buttons for approximately 12 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Allow up to 90 seconds for the reset to complete.
  3. If Maintenance Boot Mode screen won’t show, then your device does not have it. Simply wait for the device to power down completely.

S10 keeps losing signal fix #4: Reseat SIM

One of the basic things that you can do when dealing with any network issue is to disconnect the SIM card temporarily. It’s mainly useful if you have a GSM device but can also work even if you have a CDMA phone. Before you disconnect the SIM card, make sure that your device is OFF. This prevents data from being corrupted when a SIM card is suddenly taken out. Make sure to keep the phone off when re-inserting the SIM back.

S10 keeps losing signal fix #7: Observe on Safe Mode

In some cases, your S10 may keep losing signal because of a bad third party app. To check if that’s the case, you can run the phone on safe mode. In this mode, all third party apps will be suspended so if your S10’s signal becomes stable, that’s a sign that one of the apps is to blame.

To run your S10 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.

  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 touchscreen 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 is still problematic, repeat steps 1-4.
