Troubleshooting Galaxy S10 that keeps losing signal
Service and reception issues aren’t always serious problems. They may happen from time to time but they don’t stay long in your phone. In fact, most of the time when your phone loses signal, it’s just a glitch but since we don’t know for sure why it’s happening on your Galaxy S10, then you need to do the following:
First solution: Use your phone in Safe Mode
This is to know if the problem occurs even if all third-party applications and services are disabled. There are times when third-party applications cause the phone to lose signal that’s why it’s important to do this. Assuming that the phone doesn’t lose signal in safe mode, it means that there’s a third-party application that causes the problem. Find out which is the culprit and get rid of it. Now, here’s how you run your phone in safe mode:
- Turn the device off.
- Press and hold the Power key past the model name screen appearing on the screen.
- When SAMSUNG appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
If the phone still keeps losing signal even in safe mode, then you must troubleshoot your phone’s settings and firmware instead.
Second solution: Reset Network Settings
This procedure will cover all other possibilities so instead of going through all the hassles of checking whether or not the flight mode is disabled or if some network settings have changed, you just have to do this one single procedure to rule them all out at once. The following changes will occur (and many more) once it’s done…
- Stored Wi-Fi networks will be deleted.
- Paired Bluetooth devices will be deleted.
- Background data sync settings will be turned on.
- Data restrictive settings in applications that were manually turned on/off by the customer will be reset to the default setting.
- Network selection mode will be set to automatic.
Now, here’s how you reset all network settings on your Galaxy S10:
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap Settings > General Management > Reset > Reset network settings.
- Tap RESET SETTINGS.
- If you have set up a PIN, enter it.
- Tap RESET SETTINGS. Once complete, a confirmation window will appear.
After this, continue using your device to know if the signal still cuts off and if it still does, then try the next procedure.
Third solution: Perform the Master Reset
At this point in time, it’s necessary to perform the master reset which will rule out the possibility that it’s just a result of a firmware problem. Your phone will be brought back to its default configuration and more often than not, this procedure will fix whatever the problem is. However, make sure to backup your important files and data as they will be deleted during the process especially ones that are stored in your phone’s internal storage.
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Galaxy S10 logo shows, release all three keys.
- Your Galaxy S10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step.
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
