.smt files are taking up a lot of space. What are they and can they be deleted
See .smt File Extension - Software to open smt files
I guess they are OK to delete but not sure what happens if you delete one which is in use. Did they come with the phone or have you downloaded themes from somewhere?
They come with the phone. I have deleted them and they just rebuild. They take up about 300 - 400 mb.
Separate names with a comma.
