Don't worry. You still have a chance to get them back, but you need to keep this in mind: Stop using the device to take new photos or videos, text messages or make calls after you lost data. It will ensure you a better chance to recover them. Then find a Samsung Android data recovery program to recover them ASAP.
Before you do anything else, download and install a reliable photo recovery program on your computer: Wondershare , trustworthy and professional software. You can use it to recover deleted pictures, video, contacts and messages.
