The latest updates on WhatsApp are all about personalization. After updating to the latest version of the app on Android and iOS, you can assign different wallpapers to chats with all your contacts. Not only is it aesthetically pleasing, but once you get used to the wallpapers mentioned above, it also acts as a visual indication that you are sending the right message to the right person.
There are also a handful of them. They fall into two categories: dark and bright. The app can also be synced with system settings, so turning on dark mode will also switch the app to dark mode. In addition, you can change the color of the default Doodle wallpaper.
Another minor, but quite useful change is the ability to search for stickers using emoji or text. Similar to Telegram, related sticker suggestions will pop up.
