What *currently* happens to zombie tags?
How do I remove/request removal of a tag from Stack Overflow?
The tag androind should probably be deleted; it appears to be a misspelling of 'android'.
Meta Stack Overflow (this site) is the correct place for requests like that.
For what it's worth, if there is a single question with such an incorrect tag, just correct it. Once the tag is no longer used for a question, it will eventually be deleted automatically. Your androind example no longer has any questions attached to it, so it will be gone soon.
If there are many questions with a faulty/problematic tag, just bring it up here on Meta and the community can decide on the proper course of action.
