LG G6 Troubleshooting

If the phone does not respond to attempts at powering on, see these possible underlying causes:

First check to see that your phone has enough battery. If not, plug it into your charger and let it charge for awhile. If the device will not charge, there are several issues to investigate. See this guide for further instructions.

If the device will charge, but the rear power button does not work, it may need to be fixed or replaced. See this guide for further instructions.

Charging ports can be a weak spot on many phones because they are one of the only exposed components. Check for any dirt or debris in the charging port and carefully clean it out with a toothpick or similar tool. If cleaning the port does not resolve the issue, it may need to be replaced. See this guide for further instructions.

If the charging cable is not the problem, you may have a faulty battery that needs replacing. See this battery replacement guide for further instructions.

If charging problems persist, the issue may be on the motherboard. See this guide for replacement instructions.

If the device battery percentage will not increase, see these possible underlying causes:

Sometimes running too many apps at once can affect the charging speed.

To close apps running in the background, press the square button at the bottom right-hand corner of the screen. Find apps that are no longer in use and press the ‘X’ button on each window to close it.

Check the ends of your charging cable for damage as these areas see the most wear and tear. If the cable is damaged, use another cable. If available, try multiple cables.

If the cable is not causing the issue, the problem may be with the charging port. Charging ports can be a weak spot on many phones because they are one of the only exposed components.

Check for any dirt or debris in the charging port and carefully clean it out with a toothpick or similar tool. If cleaning the port does not resolve the issue, it may need to be replaced. See this guide for further instructions.

If charging problems persist, the issue may be in the battery. See this guide for replacement instructions.

If charging problems persist, the issue may be on the motherboard. See this guide for replacement instructions.

If the phone does not respond to touch inputs and/or button inputs, see these possible underlying causes:

Clean the screen with a soft cloth or special wipe.

Restarting the phone refreshes the memory and can clear up minor issues.

If you are unable to restart the phone via the touchscreen or power button, you can perform a soft reset. Hold down the power button for 10 seconds, or until the device begins to restart.

If the soft reset does not resolve the issue, you may perform a hard reset, or factory reset. Hold down the power button and volume down key at the same time. When the LG logo is displayed, release the power button momentarily and then hold it down again. Make sure to keep the volume down key pressed the whole time. This should bring up the factory reset menu and clear up any corrupted data issues.

If your touchscreen is unresponsive, the digitizer may be broken and need replacing.

If the phone continuously restarts, showing the LG logo or if the phone displays green screen upon start and constantly powers on and off to this screen, see these possible underlying causes:

There may be applications that are resisting the capability of restarting the phone.

With the screen on, press and hold the power key.

When an options menu appears, press and hold power off.

Message “Restart in Safe Mode” will appear, tap ok.

Device will restart in safe mode.

Navigate the menu to delete recently installed applications.

If you have performed software modifications to your device (custom ROM or rooting), you may have corrupted your device. It is recommended that you contact LG for steps to restore your software to its original state.

If the fingerprint scanner will not unlock phone after being initiated, see these possible underlying causes:

Dirt and oil may build up on the device and impede its ability to function properly.

Power off device.

Use the solution to dampen a microfiber cloth and gently clean the outside of the phone. A 30% / 70% solution of water to isopropyl alcohol is recommended but distilled or bottled water will work.

Check to see if this resolves the issue.

From the home screen select Settings>Lock Screen>Fingerprints>Manage Fingerprints.

Select the delete icon (trash can) to the right of the desired fingerprint and confirm.

Rescan your finger.

Deleting original fingerprint ID file in the phone:

Some users have experienced success resolving the issue by turning off the “Always On” display setting.

If the phone displays a warning that the phone is too hot, see these possible underlying causes:

Overexposure to direct sunlight.

Place the phone in an area of a lower temperature away from direct sunlight.

Use of too many phone applications running in the background.

Kill as many running applications as possible.

The brightness of the phone screen is raised too high.

Turn the brightness down to as low as possible.

The phone case is constricting the phone to cool properly.

Take off the phone case while the phone temperature is cooling down.

If a notification or phone call from the phone will only play a ringtone or stay silent, see these possible underlying causes:

The vibrate function is not selected in the phone settings.

The phone is on silent. It will not ring or vibrate when receiving any notifications.

Open the Settings application and select the ringtone options.

Select the vibrate option to "On".

Press the two volume buttons on the left side of the phone to change the volume settings and turn off silent mode.

If the vibrate function is still not working, the motor may need to be replaced. Follow this vibration motor replacement guide for replacement instructions.
