LG G4 Troubleshooting
Phone Won't Turn On
No matter what you do, you can't get your phone to turn on.
If your phone won't turn on, and you have not used it in a while, you may simply have a drained battery. There are a few things you can try: Connect it to a power cord and see if anything happens. It should recognize that it has been connected to a power source by lighting up and start charging. If that does not happen, inspect your cord and power wall adapter and see if there is any damage to either one.
Dust or dirt can spoil the sensors and prevent proper connection between the battery and the phone. To clean this up, use a cotton swab and alcohol to remove the dust from the sensors.
There may be damage to the panel due to different causes such as water or impact when dropped. The volume/power panel is a very quick and easy fix with the right replacement parts.
Charging Port is Malfunctioning
If you try a functioning charging cable and it does not work, there might be a problem with the port. This will require replacement of the charging port.
Display is Not Working
The display does not turn on when the phone is powered on.
If the display is blank or has spots, this can be because the display is damaged. This can be due to liquid or physical damage, and may require a screen replacement.
Digitizer Not Working
If images are visible on your screen but the touch pad is not responding, the digitizer might not be connected properly or might be faulty. To fix this you will need to check the connections, if they are good, digitizer replacement is required.
No Audio or Distorted Audio
No audio or distorted audio can be heard during a phone call or while playing music.
Check to make sure that your device volume settings are appropriate. If they are not, set them to your preference.
Check speaker to make sure there is no moisture, dirt or another particles on or around blocking it. Clean it with an air duster.
Front or Back Camera Not Operational
You are trying to take a picture or video with the front or back camera, and you only see a black screen.
Camera Not Available Due To A Low Battery
The camera might not work due to a low charge in the battery. Charge your phone and try again.
Camera Application Crashed
If the camera application is open but it is not responding, try closing out the application and reopening it. If that does not work, try rebooting the phone.
If you are trying to open applications and they keep closing out and directing you to home screen.
If the application fails, try closing it completely and reopening it. If that does not work try rebooting the phone.
If the application does not work after rebooting the phone, try uninstalling and re-installing the application.
Phone System Crash
If multiple applications are consistently failing try hard resetting your phone. This will delete all the information on your phone including pictures and contacts.
