Recovering deleted photos - free - Samsung Galaxy Core Prime

Hi,
I need some application which is able to recover my deleted images from phone Samsung Galaxy Core Prime. I tried to find something but all is paid. Exists something for free or some other easy way how to get photos back? Thanks for each idea.

Paid applications:
GetDataBack
Wondershare
Android photo recovery
Recover - from UndeletePlus
EaseUS® Data Recovery
Remo Recover
