Galaxy A52, Galaxy A72 official unboxing videos
Apart from the smartphones themselves, the boxes of the Galaxy A52 and the Galaxy A72 contain quick start guides, SIM ejection pin, data cable, and a travel charging adapter. While both smartphones are capable of 25W fast charging, only the Galaxy A72 comes bundled with a 25W Super Fast charging adapter and a USB Type-C to Type-C cable. Samsung decided to do a little cost-cutting with the Galaxy A52 (and the Galaxy A52 5G) and it is including a 15W Adaptive Fast Charger and a USB Type-A to Type-C cable.
Both smartphones are available in four colors: Awesome Black, Awesome Blue, Awesome Violet, and Awesome White. The Galaxy A52 and the Galaxy A72 smartphones run Android 11 (with One UI 3.1) out of the box and are bound to get three major Android OS updates and an additional year of security patches. The unboxing videos go on to show how to start the phones, the setup process, how to charge them, and how to pair them with Galaxy Buds wireless earphones.
