How to remove encryption?

[enica]

So yesterday I encrypted my phone and can't now remove it. All the other options are grey and unclickable, so is the clear credentials option. I don't even know why it won't let me go back to slide mode because I have removed encryption before without any issues. I also don't want to delete all the phone data. Is there any other way to remove encryption?

Welcome to Android Central! Which device? Encryption is usually irreversible, requiring a factory reset to remove. How did you remove it before, and on which device? The same one?
