WhatsApp, a popular instant messaging platform, is constantly experimenting with new features to ramp up user experience. Speaking of which, WhatsApp is working on a large link preview for iOS to make it easier for users to check out what the links are all about. The feature has been spotted by WABetaInfo, a popular website that pushes regular updates around WhatsApp.

According to WABetaInfo, the large preview link feature is currently under development and will be available for users in a future update. WhatsApp is working on the same feature on the Android app and bringing high-quality previews for URLs on the latest beta version. Moreover, if some websites don’t have a high-resolution preview for URLs, which is why WhatsApp will show a smaller thumbnail.

In other WhatsApp-related news, WhatsApp's Beta users are currently testing a brand new feature where attached images or videos disappear after one viewing - very similar to Snaps on Snapchat. The feature allows WhatsApp users to send a photograph or video that will delete after being watched or viewed.

Also, WhatsApp is restoring the green colour notifications for its Android beta app. WhatsApp had first announced a new dark blue colour in notifications in the 2.21.12.12 beta update. However, WhatsApp is now restoring the old colour again. This is because the new blue colour wasn’t appreciated much by users.

“WhatsApp has reverted the changes, restoring the old green colour. What is the reason? Some users complained that the new colour wasn’t correctly visible in the notification, due to its contrast: probably WhatsApp has listened to the feedback, restoring the green colour”, revealed WABetInfo.
