 ■ What is FOTA (Firmware Over The Air)?

FOTA is a wireless tool to update SW of smart phones. This method is recommended for customers’ convenience and also they do not have to do anything to use FOTA. If the mobile phone supports FOTA, you can download the firmware update over the air directly from operators (In case of  Operator FOTA as ATT, Tracfone, Verison ) or LGE (for most cases).

It also allows manufacturers and operators to "push out" firmware updates to ensure their consumers have the latest software improvement, which helps to save time and cost and increase consumer satisfaction.

  ■ How can I check if the software is the latest version?

Go to Settings  → General Tab About phone → Update Center → Software Update → Check now for update
