GIF's are so popular. Everyone loves them and memes. It's how the internet works. A GIF is a moving image that's shorter than a video and easy to share in text messages, emails, chat boards, Facebook and other social media sites.
Similar to the Galaxy Note 7, the Galaxy S8 have a "GIF MAKER" tool built right into the video player on the phone. Simply open the gallery and play any video you have on the phone. While it's playing hit the "GIF" tool in the middle bottom of the screen. Now you can crop the image to make the perfect size GIF, increase or decrease the speed and do other edits. Then save and share a GIF of funny moments, movie clips and more all right on your device. It's a game changer.
