The problem might arise due to overload of the phone. Customers who get too excited to hold this feature packed techno marvel in their hand often open several applications at a time. They seldom care to close it properly. While most phones do not make it an issue, LG G3 gets enormously slow when numerous applications are opened at a time. To close them go to Settings > App > Running and close all the opened applications. Keep only one or two important constantly used ones like WhatsApp open.
