Although the tweet doesn't specify what phone this is, a report by AllAboutSamsung says it could be the next Galaxy A9. Samsung's Galaxy A line tends to be reserved for the company's midrange phones -- compared to the Galaxy S and Galaxy Note series -- but Samsung said it would be bringing more premium features to its midrange devices.

This four-camera phone includes an 8MP ultra-wide-angle camera, a 10MP telephoto camera, a 24MP main camera and a 5MP depth camera. With all these different cameras serving different purposes, the Samsung Galaxy A9 may be able to take a wide array of photos.
