The good news is that according to a report from WABetaInfo, it appears that WhatsApp is now testing out showing profile pictures in notifications on iOS devices. This means that you’ll soon be able to better distinguish who sent you a message based on the profile picture alone. This could be useful if your phone is locked but you still want to see who it’s from, and from there you’ll be able to decide if you want to reply that message now or later.
That being said, as WABetaInfo notes, this is a feature that’s currently in testing which means that not everyone will be able to see the changes. It is only available to some beta testers, so if you’re not part of the WhatsApp for iOS beta, then obviously you won’t be able to see the new feature.
There is no mention of when WhatsApp plans to push out these changes, but since it’s not exactly a groundbreaking feature, we won’t hold our breath for it, but we’ll keep an eye out for it all the same.
