All good things must come to an end, even your relationship with your phone. This means at some point you may need to reset your LG G4. But it’s not the only reason to do it.
Your LG G4 comes from the factory just about as clean as it will ever be. You haven’t filled it up with apps and photos yet. It’s not littered with folders from apps you installed, used for two days, then uninstalled. You haven’t messed with the settings and forgotten what you did. So when your phone starts to slow down, or when a bug rears its ugly head and regular troubleshooting fails to fix it, you can always go nuclear with a factory reset.
Make sure your backups are current and let’s hit the reset button.
