About 8 months ago I transferred data from my old phone to my new phone realme 5 pro. About 4-5 days later Data of old phone was accidentally deleted by me. Although that was my fault. My younger brother advised me to restore photos from disk drigger app. I installed the app and I was very happy that all photos will come again. This app scanned approximately 4500 photos.
I started seeing photos one by one. But I got no photos, all photos was belongings to the picture taken by new phone and rest of the photos were from PDF files, song title photos, half of the photos were repeated form of rest photos, and some photos I don't know where it came from.
So the conclusion is that I was not able to get even single photos. Don't know how people use it so they get back their photos. My experience was not good.
