I have many photos and recorded videos stored on my Xperia Z3. Most of them are about the elections in 2016. I deleted the whole folder by accident. It seems no trash bin folder on a phone. Then what to do to restore the photos and videos? thanks
You have great possibility to retrieve your photos you mistakenly deleted from Xperia phone, it's Android phone. Those photos are still in the memory of your phone just not visible, and pics data are waiting to be written over by new data. So from now on don't use your phone to take more photos, and try Android data recovery program to scan your Android phone.
As far as I know, Mobiledic Android data recovery program can deeply scan internal memory and SD card. Hope it works.
