Hi, sorry to say, but here’s the rub: if that Galaxy Tab S9 FE isn’t rooted (and I’m guessing it’s not), the chances of recovering deleted photos are basically zero. That tablet is from 2023, so it’s got modern encryption, and like all newer Androids, it uses TRIM (which wipes deleted data almost instantly to keep the storage fast).
Free or paid software doesn’t really matter in this case, they all run into the same roadblocks without root access and with TRIM active. I know that’s not the answer you wanted, but it is what it is.
