I accidentally deleted a very important recording from the voice recorder app on my phone. Is there any way to retrieve that if it’s been deleted?
Do you back up data to your Cloud? If so, I'd start by looking there first. There are also some apps out there that supposedly work, but I don't have first hand knowledge.
unless the app has a function similar to yahoo mail, when email/s are deleted, you're asked to confirm, the recording is gone.
