For LG devices, there is unfortunately no function to simply remove an entire folder from the home screen. The folder is then automatically deleted if there is only one app left in the folder. A quick removal, especially for folders with multiple apps, works through the folder's edit function.

After deleting the folder, all apps are reintegrated on the home screen.
