I’m going off of an informed guess, so don’t quote me on this one. But it could be irrecoverably deleted.
Usually phone storage is encrypted, and it gets decrypted with your PIN. The whole file isn’t actually encrypted with the PIN, it uses way more secure passwords, and it uses different passwords for different pieces of the data. Those passwords are basically impossible to crack, and even if you cracked one, you’d get a very small piece of all the data. Of course, you can’t memorize all those, so they get stored in a sector called the encryption header. That sector is what the PIN decrypts, and everything else is decrypted with the passwords in the header.
Most of these “quick deletion” systems don’t even delete anything from the drive. They just delete the headers. They’re small enough that you can overwrite them multiple times in a very short time, so you can properly blank them. Without the headers, the rest of the drive is virtually impossible to decrypt, so the data is as good as gone.
