Fixing Switch home screen lag makes navigating your console smoother. First, restart the Switch by holding the power button for 15 seconds—this clears temporary glitches causing lag. Delete unused games and apps to free up internal storage: go to 'System Settings' > 'Data Management' > 'Manage Software' and remove games you don’t play. Move games to a microSD card (if using one): use 'Move Data Between System/microSD Card' to offload data from internal storage. Update your system firmware to the latest version—Nintendo often releases updates that improve performance. Disable background downloads: go to 'System Settings' > 'Internet' > 'Download Management' and pause any ongoing downloads. If lag persists, perform a factory reset (without deleting save data): 'System Settings' > 'System' > 'Formatting Options' > 'Initialize Console Without Deleting Save Data'—this resets system settings without losing progress.
