Fix Your LG G3

This guide contains the most common issues and suggested fix to fix your own LG G3 – and save costs repairing it.

LG G3 Won’t Charge

This is usually related to the battery not being properly installed and most of the times, and if it won’t power on due to the battery being drained then try re-installing the battery. In order to replace the battery, you will need the following two tools: A #00 Screwdriver and a Metal Spudger

Once you are in possession of the two tools, do this:

1. Take the phone, and place it down, see image below:

2. Lift the back panel using the gap located on the bottom left side then insert the plastic opening tool into the gap, and move it along the edge until the rear case ejects itself. After it pop’s off, remove the battery and make sure it is correctly installed, if not then install it correctly. If it still won’t power on, then get a new battery , get it only if your phone is out of warranty, if it is in warranty then you should send it to the retailer for replacement.

The above instructions will work in replacing/resetting the battery.
