How to remove added ringtone I have added a new ringtone to the ringtones list in Settings->Sounds->Phone ringtone>Add ringtone. After that I can see the same ringtone file in Ringtones folder of Internal storage. I need to remove this ringtone? For that I have deleted that file from folder. But, the ringtone is still running there. How to remove it.

Device: Moto X4 Oreo 8.0 (non rooted)
Don't clear data of Media Storage (System App) as mattm suggested, you'll lose all ringtones and sound effects.

Instead, do a search for the ringtone or sound effect you added using the Files app (comes with Android), then erase it. It'll be removed from the ringtone selection menu without erasing all the other sound files.
