Comparisons Featuring Celkon A21
Short Review
- The Celkon A21 features a compact design with dimensions of 124.8 x 66.1 x 10.8 mm and a weight of 115.3g, making it lightweight and easy to handle.
- Its 4.0-inch TFT display has a resolution of 320 x 480 pixels, resulting in a pixel density of approximately 144 ppi, which is adequate for basic tasks but lacks sharpness.
- Performance is driven by a Mediatek MT6582 chipset with a quad-core 1.3 GHz Cortex-A7 CPU and 512MB of RAM, providing limited multitasking capabilities.
- The camera system includes a 3.15 MP rear camera and a 1.3 MP front camera, suitable for basic photography but lacking advanced features like OIS.
- The 1500mAh battery offers minimal capacity, which may require frequent charging under regular use.
- Running on Android 4.2.2 (Jelly Bean), the software experience is dated and may not support newer applications.
- Connectivity options include Wi-Fi 802.11 b/g/n and Bluetooth 4.0, but it does not support 5G or NFC.
- The device is equipped with a microUSB port for charging and data transfer, while a headphone jack is included for audio needs.
- Available in black, blue, and red, the Celkon A21 offers basic functionality without any standout features.
- Overall, it serves as a simple device for essential communication and light usage.
