How-to recover any deleted files/photos/videos on your Android phone

The most valuable information on your Android devices are your pictures, files or video. And we’ve all accidentally mistakenly hit the delete Button without knowing what else to do. But don’t panic; you can recover everything you’ve accidentally deleted on your phone.
There are many app on play store that will help you to recover deleted files but lets use DISKDIGGER

DiskDigger can undelete and recover lost photos and images from your memory card or internal memory. No rooting necessary!  Whether you accidentally deleted a photo, or even reformatted your memory card, DiskDigger’s powerful data recovery features can find your lost pictures and let you restore them.

The free version of DiskDigger can recover photos and videos only (recovering videos requires your device to be rooted).

The Pro version can recover other types of files besides photos and videos, and also allows uploading recovered files over FTP (again, recovering any types of files besides photos requires your device to be rooted).
