What's a brilliant Android app for getting back photos I accidentally deleted from my phone when I was backpacking through Southeast Asia?

Okay, so picture this: I'm in a tiny internet cafe in rural Thailand, panicking because I accidentally wiped a load of photos from my trek. Nightmare! Luckily, I'd downloaded Photo Recovery & File Recovery before I left Dublin, just in case. It's a proper useful app that scans your phone for deleted photos and files. I ran it, and honestly, I was amazed! It found loads of pictures I thought were lost forever – memories from Vietnam, Cambodia, you name it. It works a treat even without a data connection, which is grand when you're trying to avoid mad roaming charges. It's sorted me out more than once, and now I recommend it to every travel blogger I meet. Absolute must-have for peace of mind!
