I don't know of any decent software for phones but I have used stuff on my desktop and laptops before to retrieve files that I've deleted. It wasn't always successful though. Even zero filling and random 1's and 0's don't completely remove all files sometimes. It's why they have options for multiple over writes.
Might have to research phone forensic undelete software or phone apps. I think it's possible until it gets overwritten.
