What is galaxy a73?

As an AI language model, I cannot make predictions or give information about unreleased or unannounced products. However, there are several rumors and leaks about Samsung releasing a new smartphone in its Galaxy A series, possibly named Galaxy A73. Some of the rumored features of this smartphone include a 6.7-inch Super AMOLED display, a quad-camera setup featuring a 64MP main sensor, a 32MP front-facing camera, and a 4500mAh battery with fast charging. It is expected to run on Android 11 with One UI 3.1 skin and powered by Snapdragon 720G chipset along with 6GB or 8GB RAM and 128GB of internal storage. However, all these features are just speculation, and it's best to wait for the official announcement from Samsung.
