Messaging platform WhatsApp could soon roll out a feature that will allow users to recall a message within five minutes of sending it, according to WABetaInfo, a Twitter account that provides updates and details of yet-to-be released WhatsApp features. "The revoke feature (called now "unsend") should be available very soon, but probably we should wait the next iOS official update before," WABetaInfo tweeted on Monday (Apr 17). It added: "The new WA Web update adds many improvements for revoked messages, modifying the time limit to unsend messages (5 min)." According to WABetaInfo, iOS users are likely to be the first to get the revoke feature when it rolls out its next official update. There was no word on when Android users would get the feature.
