Reviews for the realme C21Y

81% realme C21Y review: Decent budget phone with NFC and 5000 mAh
Source: Root Nation English EN→zh-CN
The realme C21Y is a decent entry-level smartphone for those looking for a basic device. The C21Y has a pleasant design and good ergonomics, a fingerprint scanner, an NFC module, excellent battery life, quite good performance and a competitive price tag. Yes, the cameras are mediocre, the speaker’s location is not the best, and I would like a slightly better screen, but for an ultra-budget device, all these issues are forgivable. For this price, the realme C21Y is a good choice.

Realme C21Y Review, Pros and Cons
Source: OI Spice Tech News English EN→zh-CN
Although the phone’s layout appeals to you, it doesn’t have the ability to satisfy your satisfaction because there are lots of flaws. With its lower standard specs, it’s not worth your money, whereas with the C25s phone you’re getting a lot more. Whatever you spend, whether small or high, it is always advisable to buy the best. What’s more interesting is its battery and better graphics unit. So far, these are just the important specs and nothing else that could be considered better in the current market. It recommends looking for an alternative option. You can check for Redmi Note 9 5g, or better have Samsung Galaxy F12 with much more advanced and attractive features.
