A close relative of the original Realme C21 smartphone, with the only difference being that the Y modification is powered by another entry-level mobile processor, the Unisoc Tiger T610 octa-core processor. Together with him "under the hood" the device has 3 GB of RAM and 32 GB of non-volatile memory. A triple tray for two SIMs and a microSD card allows you to expand the capacity of a regular drive without having to compromise.

An IPS screen with a teardrop notch in the upper segment and a small “chin” at the bottom extends across the entire plane of the Realme C21Y 32GB front panel. The display measures 6.5" diagonally, but the image resolution on it is small — 1600x720 pixels. On the side of the back with an X-shaped pattern, the model is equipped with a triple camera 13 + 2 + 2 MP and a round platform for a fingerprint scanner. A capacious 5000 mAh rechargeable battery is hidden in the depths of the body of the device with charging at a standard pace through the contacts of the microUSB connector. In our markets, a smartphone usually comes with an NFC.

Model overview based on user reviews  
The Realme C21Y 32 GB / 3 GB is a budget-friendly smartphone that offers a solid performance for its price. It features a fast and reliable processor that handles basic activities and some gaming smoothly, making it a suitable choice for users who enjoy mobile games like PUBG and Call of Duty. The phone includes NFC for contactless payments, which is a valuable addition in this price segment. It also boasts good battery life, lasting about a day and a half on a single charge. The interface is simple and clean, providing a straightforward user experience. However, the phone's camera quality is lacking, and the screen may have brightness issues and potential problems with certain settings. The build materials are not premium, and it uses a micro USB connector, which some might find outdated. Despite these drawbacks, the Realme C21Y is appreciated for its overall performance and features, making it a reasonable choice for budget-conscious consumers.

Budget smartphone for basic activities
9 December 2023 
A budget phone that justifies itself. The processor is not very powerful but sufficient for videos, social media, communication, and GPS. The RAM and memory work fast for this category. The screen lacks brightness; only at maximum setting does the sun not cause issues. The sound is loud but not for audiophiles. There is no fast charging. NFC is available and works excellently. Geolocation functions well too. Though it's far from a flagship, I am satisfied with its performance. The materials used aren't great, though the assembly is good. Over-the-air updates still keep coming. There are many features I don't use. It comes with pre-installed apps. You shouldn't play games on it, as it heats up and throttling is noticeable.

The phone is good for its price, operates quickly, nothing unnecessary, bright screen, clear sound. I hesitated when buying because I didn't know the brand, but I bought it and never regretted it. I recommend the phone.
Fast, doesn't lag, menu is as simple as possible without anything unnecessary that could interfere with the phone's operation, screen is excellent.

I don't recommend this phone. I had it for only 5 minutes and the screen was dimming every half second. Then I went into settings, clicked on high contrast, and boom, a black screen. I set it up to display on the computer, turned off high contrast, and it was still a black screen. If there was an ultra-critical rating, I would give it.
