Solved! How to I retrieve photos on my (SAMSUNG Galaxy J3e Cell Phone) that were accidenttely deleted?

Assuming you did not make any backups to cloud storage, your computer or an external card, check here http://www.tomsguide.com/forum/id-1640133/recover-lost-smartphone-data.html

If you did not have backups and you can't get it from the file recovery, you can try some data recovery apps from the Play Store but those all require the phone to be rooted, so you will need to do that first to your device.
