Wipe and Secure Your Mobile Devices

So, you “delete” your data, but what happens to those “deleted” files? Time ago, I deleted some pictures in my old iPhone because I was running out of space, but I was shocked when I bought a new iPhone, and then all those "deleted” pictures suddenly came back to my phone. I was in doubt about if I had sold my phone without wiping data because I only deleted data, but it could just appear in my old phone just as it happened to me. Fortunately, I had no confidential or private data, but at this point, I feel afraid about how harmful an event like this could be.
