NIU C21A Overall Review

The NIU C21A, released in April 2013, is a classic representation of a feature phone, designed for users who prioritize simplicity and basic functionality over the complex features of modern smartphones. Weighing just 73g (without the battery) and with a thickness of 14.5mm, it’s a lightweight and compact device that offers straightforward usability.

The C21A is equipped with a 1.8-inch display, supporting a resolution of 128×160 pixels, which is typical for phones of its class, ensuring clear visibility for calls, texts, and basic interface interaction. The inclusion of a 0.3 MP camera allows for basic photography, capturing moments in a very rudimentary form. This phone doesn’t support video recording, which aligns with the expectations for a basic feature phone.

With 32Mb of internal storage and 32Mb of RAM, the C21A meets the minimal requirements for storing contacts, messages, and a few media files, with an option to expand storage via a microSDHC slot. The phone’s simplicity extends to its connectivity options, focusing on essential features like calling and SMS.
