Our take on the Samsung Galaxy A16 5G (SM-A166U) AT&T Locked 128GB

The Galaxy A16 5G is Samsung's budget 5G phone: a 6.7-inch PLS LCD, a MediaTek Dimensity 6300 chip with 4GB RAM and 128GB storage, and a 50MP main camera backed by a 5MP ultrawide and a 2MP macro. It suits buyers who want a big screen and long software support on a carrier-locked AT&T device. Against rivals like the Moto G 5G and Redmi Note line, it trades raw power and a sharper display for Samsung's longer update promise and One UI. Reviewers call it a solid everyday phone but note the 4GB RAM and LCD panel show in heavy multitasking.
