n80 theme problem

Try install again, and see if they appear!

Have a look at Darla Mack's blog - she's goat an article on how to remove themes.

True. With some work but is possible remove all.😎

There is a way but it's not straightforward.

First, you need to connect the phone in Data Transfer mode.

Set your computer to view hidden files and folders.

The name of the themes on the phone are not always straightforward, sometimes they appear only as numbers. A way to identify what's what is this:
Name (or rename) any photo on your phone with the name 'delete'. Edit each theme you want to get rid of by changing the default wallpaper to the picture file called 'delete'. This causes the theme to be appended with the name of the user defined wallpaper file.

Back on your computer, search the drive letter that your phone has been allocated in My Computer for the word 'delete'. Every folder it finds is one of the themes you want to get rid of. Delete them. You may have to restart the phone but when you have the theme should have disappeared from the list. Worked for me, anyway.

I know I may not have explained that too well. See how you go and if you get stuck post again and I'll see if I can explain some more.
