Have transferred all music to SD card but still seem to have full system/ user data


My galaxy S7 external SD card seemed to have stopped working. Which caused my phone to show full internal storage. I replaced the SD card with a new and larger one and transferred all my google play music to it. My phone is still showing full storage. 30.5 GB of storage is consumed by userdata/system. I removed the external sd card and checked if the google play music was showing any data still. No data is showing. So I can not for the life of me figure out what data and where is consuming all my storage.

Next step is clear the cache.

Last step is master/hard reset. Really don’t feel like that though.

Ideas?
