koshergood LG Settings is not an accessibility service. It has to be launched using ListLauncher because it is not an Apps4Flip app, it's a system app from another phone, and smartphone uses a different main activity for settings, preventing it from showing up on the standard FPHome home screen.
com.android.settings.LeapSettings or similar is used on the Exalt and Classic by default
com.android.settings.MainSettings is standard smartphone settings main activity, but in the Flip stock APKs it just has a jump to the Leap equivalent.
