For persistent problems, consult the online LG support resources or consider a factory reset (remember to back up your data first!).
Software Updates and Maintenance
Keeping your LG G3 software updated is crucial for optimal performance and security. Regularly check for updates via LG ThinQ app or within the phone’s settings (Settings > About phone > Software update). Updates often include bug fixes, performance improvements, and new features.
