Why can’t I select a custom sound for “system sound”? Uncategorized June 24, 2021 Forums AndroidCentralLeave a Comment on Why can’t I select a custom sound for “system sound”? I would like to use a custom sound (from zedge) for my "system sound" in the settings. However, it will only allow the 4 default choices (galaxy, calm, fun, retro) in the system. It won’t accept any other choices for choosing a new sound. Sharing is caring!
