According to a report by WaBetaInfo, WhatsApp is currently testing a redesign of the attachment menu for its Android app in the latest v2.23.6.17 beta build. This same interface was first introduced in a beta version of WhatsApp for iPhone earlier this month, and it now appears that the messaging service, owned by Meta, is testing the interface for its Android app.
It's worth noting that the new interface is not a significant overhaul from the current design on the Android app, but it does have a more modern appearance with updated icons. This redesigned menu offers more space for upcoming new features that WhatsApp may introduce in the future.
