  • Design

In the practice of different models in the family, the Realme C21 3GB has a good plan. You won’t be able to find any dazzling nuances or polished wrapping. The box is matte plastic with a fine surface that resembles a mathematical drawing.

The phone has an IPS display with a 6.5-inch screen and a resolution of 720 x 1600 pixels.

It has a conventional perspective ratio of 20:9, and a low pixel thickness per inch of 270, which makes a link. The width of the screen’s bezel is standard for gadgets in this price range.

A glass with a reflecting surface is seen on the front side. It is scratch-resistant. When viewed at a point, the screen has excellent survey points with no true shading variances.

The image is saturated and bright enough to work well both inside and out.

  • Execution

The phone is available in two configurations: 2 or 3 GB of RAM and 32 or 64 GB of storage. Because there is space available, the last option can be enlarged if necessary.

The MediaTek Helio G35 is a 2020 framework that will be released in the middle of the year. It isn’t very sturdy and is designed for low-level gadgets.

It’s adequate for smooth point-of-interaction execution, but not for heavy gameplay. At modest design settings, you can participate in the last option.

The device has an industrial design and runs on the Android 10 operating system with the Realme UI.Realme C21 3GB

  • Camera

The connection point for the camera is standard. The producer’s several models are notable.

A couple of new modes have been added that will keep any shooter entertained. HDR, manual mode, representation, and night mode are the most basic options.

The wide-angle super rear camera module has a resolution of 13 megapixels. Its PDAF stage discovery self-adjustment is satisfactory.

Regardless, there isn’t a stabiliser. As a result, the camera takes pictures at a budget level. With less detail, the images become more dazzling and contrasty.
