Guidelines for safe and efficient use
Please read these simple guidelines. Not following these guidelines may be
dangerous or illegal.
Should a fault occur, a software tool is built into your device that will gather a
fault log. This tool gathers only data specific to the fault, such as signal strength,
cell ID position in sudden call drop and applications loaded. The log is used only to
help determine the cause of the fault. These logs are encrypted and can only be
accessed by an authorised LG Repair centre should you need to return your device
for repair.
