I'm sure you can google android file recovery but here's why I don't advise ... after the fact ... recovery apps. These often fail because we are installing to the same area the files are stored in.
Most folk learn about all this by losing stuff. Now they are ready to talk about backup and more.
I use Dropbox on my Android devices since photos I take automatically sync. I've yet to lose a thing.
I've made a terrible misstake and accidantely deleted some photos and videos from "Recently Deleted album", and my question is if there is anyway to recover the lost files?
