Display Comparison
Both the Realme C21Y and C25Y typically feature a 6.5-inch IPS LCD display with a resolution of 1600 x 720 pixels (HD+). While the panels are similar in size and resolution, slight variations in color accuracy and brightness may exist depending on the specific production batch. Expect decent viewing angles and adequate clarity for everyday use.
Camera Comparison
The Realme C21Y generally features a 13MP main camera, a 2MP macro lens, and a 2MP depth sensor. The C25Y often includes a 48MP main camera, a 2MP macro lens, and a 2MP depth sensor.
