For example, the Galaxy A51 arrived ten months after the Galaxy A50, while the Galaxy A71 went official nine months after the Galaxy A70 (and three months after the Galaxy A70s). Devices on the lower-end of the mid-range spectrum, like the Galaxy A31, A11, and A41, will be coming out more than a year after their predecessors, so it's all pretty random at this point. It's worth noting that Wi-Fi certification doesn't necessarily mean a phone's launch is around the corner, but it represents an important step in a smartphone's path from Samsung's R&D labs to retail stores.
The Galaxy A31 will run Android 10 out of the box, as confirmed by the certification. It will bring a substantial upgrade over the Galaxy A30: The A31 will have a 5,000 mA battery under the hood, a full 1000 mAh more than the Galaxy A30. It is also expected to feature a 48MP rear camera and a 5MP macro camera like the Galaxy A51, and storage options for the phone will include 64GB and 128GB.
