Instagram has update its stories in which now you can add photos and videos taken 24 hours ago. Earlier you were only able to add photos and videos take in 24 Hours. We have seen this feature in Snapchat already.
With this update you just have to swipe up from the camera to open your camera roll or tap the gallery icon. Than scroll to choose your photo or video, and tap to select what you want to share even 24 hours old. You can add all the stickers, you can also resize and rotate it and can remove date sticker from your photo or video.
This update will be available on both the Android iOS platforms. Instagram v18 on Android will have this feature and Instagram v22 will have this feature in iOS App.
