[Android Central Question]

Hi, I really need some help restoring a memo on my phone to the state it was before all the text was deleted from it.
I was typing in one of the memos and needed to take a chunk of text out to replace it with something else. All of the text happened to be selected instead when I pressed delete and everything was gone. In a panic when trying to undo the edit, my finger accidentally hit save instead of cancel and all that was left was a blank memo.

I've been working on the ideas in it for the past 7 months, and am furious about losing them for good. Is there any way I can retrieve them by chance?
