Introducing Snapchat Memories!
You can now save and re-post Snaps and Stories on Snapchat. Save, search using keywords, replay or re-share old photos and videos. It is now the default in-app place where Snaps are saved to, as compared to your Camera Roll.
This update changes the here-today-gone-tomorrow appeal that the app’s core feature is built upon. Keep an eye out to Memories by swiping up on your Snapchat camera screen.
