Google now rolling out new Material Theme design to Gmail mobile app
This is a complete redesign that makes Gmail UI brighter and cleaner. As a matter of fact, some say that the new design is too bright and totally uninspired especially when you're opening the app in low-light environments.
The good news is Google included some tweaks as well, such as the ability to quickly view attachments without having to open or scroll through a conversation. Also, thanks to machine learning technology, Gmail enables users to write emails faster due to Smart Compose.
The same goes for replying to messages, which happens quicker than ever with suggested responses offered by Smart Reply. The new update is rolling out starting today to all Gmail users on Android and iOS, but it will probably take some time until it reaches everyone, so be patient if you don't get the new design right away.
