LG-G3.jpgHaving problems with your LG G3? Whether the front camera doesn’t work, the display doesn’t turn on, or your phone just doesn’t seem to be charging, you’ll be able to troubleshoot the issue with this step-by-step guide.
 

Phone doesn’t Charge

It takes longer than normal to charge, if at all, or phone doesn’t recognize when charger is connected.
 

Battery is Installed Incorrectly

The phone may not charge because the battery has been installed incorrectly. This could be the issue if your phone doesn’t charge, and if it doesn’t power on either. Let’s try removing the back cover, and reinstalling the battery. Here is an iFixit replacement guide: LG G3 Battery Replacement.
 

Battery is Bad

If the phone has been using the battery for a while, or if the user has used heavy applications on the phone it may cause the battery to heat up. If the user forgets the charging cable plugged in all night it will weaken the battery, especially if it was charged for a full night over multiple times. This is an easy enough fix. Start by removing the back cover. Here is an iFixit replacement guide: LG G3 Battery Replacement
 

Charging Port is Bad

Unfortunately, this requires either soldering or replacing the motherboard.
 

Display Not Turning On

The display does not turn on when the power button is pressed.
 

Battery is Not Charged

Easy fix. Plug the charger into the phone, and wait about 10 minutes before attempting to power up the device.
 

Screen is Damaged

There may be physical damage to the screen if it has been dropped or scratched without a protective case. If your phone has been through the mill and has physical damage to the screen, then you will need to replace the damaged screen. Here is an iFixit replacement guide: LG G3 Screen Replacement.
 

Front Camera Not Operational

If you are trying to take a picture or video with the front camera activated, and you only see a black screen.
 

Camera is Not Connected Correctly

The ribbon cables connecting the camera to the motherboard may not be connected, or have gotten loose after the phone has been dropped. This can be fixed by reconnecting the camera's ribbon cable to the motherboard. Find out how in this iFixit replacement guide: LG G3 Front Facing Camera Replacement
 

Camera is Bad

The camera may not be operational due to a fault in the manufacturing process, or it may possibly be damaged after the phone has been dropped. This is not too bad of an issue, so let's go ahead and replace that camera. Find out how in this iFixit replacement guide: LG G3 Front Facing Camera Replacement.
 

Rear camera is not operational

If you are trying to take a picture or video with the rear camera activated, and you only see a black screen.
 

Camera is Not Connected Correctly

This can be fixed by reconnecting the camera's ribbon cable to the motherboard. Find out how in this iFixit replacement guide: LG G3 Rear Facing Camera Replacement.

Volume and/or Power Button Does Not Respond

When pressing the power or volume button, nothing happens as expected.


Dirty Connectors

Sometimes, dust or dirt can soil the sensors and stop the users input from going through. To clean this up use a cotton swab and alcohol to remove the dust from the sensors.
 

Misaligned Sensor Pad

Sensor pads can become loose and become misaligned with the button you are trying to press. This requires that you replace the sensor pad.
 

Damaged Panel

There may be damage to the panel due to water. The volume/power panel is a very easy and quick fix with the right replacement parts.
