My phone shuts off when I try to access pictures or if I try to play a game. Anything to do with graphics seems to shut it off?
This seems to be a known issue for the LG Optimus Chic E720.
Go to the link I have provided below and enter the model number in the search box “Start by typing all or part of a model name/number” and click continue. Once there click on Software Update and download the LG Support Tool for PC. Please follow the instructions to download and install the software. Once installed please follow the instructions below the download link to update the software on your phone and it will hopefully correct this issue.
