Realme C21 price in India kicks off from Rs 8799 for the base model with 3 GB RAM variant. A more costly model is available with 4 GB of RAM and higher storage.
The Realme C21 features a relatively large 6.5 inch HD+ IPS LCD display. The display comes at a resolution of 720 x 1600 pixels with a pixel density of 270 ppi and screen to body ratio of 80.8%.
The Realme C21 includes a triple camera system that includes a 13 MP f/2.2 primary camera with phase detection autofocus, a 2 MP depth camera, and a 2 MP macro camera. The camera system is equipped with HDR, panorama, and an LED flash. There is also a 5 MP camera with HDR and panoramic capability for selfies, as well as support for 1080p films at 30fps for video calls.
Realme C21 does not feature all latest connectivity standards. Commonly found standards like the WiFi n and Bluetooth 5.0 LE are present in the smartphone. The microUSB port on the device supports OTG and has USB 2.0 speeds.
Realme C21 is a budget device with uninspiring design and specs. For the price, the mediocre performance is not an issue. Moreover the Realme mobile has excellent battery backup.
Pros: Good Performance, Value for Money
Cons: no WiFi ac, Front Camera is not on par with competition.
