Are there any better file recvovery programs for android about?

[helloeverybody]

I thought it would b worth trying to restore the half a bitcoin or however much it was i lost when i factory reset my old phone some time back. It wasnt too bad of a loss a while back but it would be nice to recover now. Does anyone know of something that would be capable of doing this? Most recovery programs ive tried only recover photos or texts etc, I had an actual backup of a wallet on the phone except it was stored on the phones internal memory which obviously didnt survive the factory reset.

Any ideas?

You definitely will need to have root access. If your phone has been used for sometime, it is impossible to recover them. Recovery programs only works when the phone hasn't been touched since the root access. Once you start using the phone, the blocks of memory labeled empty will be overwritten.

STOP USING THE PHONE RIGHT NOW!
By installing apps on it, you're just going to overwrite the data on your flash storage, and that significantly
 increases your chances to lose the data.

Instead, you need to dump your flash into an image and dig that further (that still might require rooting your phone).
You also can contact a professional data recovery service, or dump the flash chip manually with a programmer, but that's a very advanced level.
