Celkon is rapidly making a name for itself as a manufacturer of quality budget smartphones. The A20 is sure to enhance this reputation, since it comes with nice features, including a good display, a dual core processor, latest Android OS and sufficient connectivity options. Internal memory is a disappointment no doubt, but even then, this device packs enough power to be considered as one of the best Android devices available in the budget segment.
Display and Configuration
Celkon's latest offering comes with a 4 inches WVGA (480 x 800 pixels resolution) TFT display with 16M colour depth for a superior visual experience. The device runs on the latest Android 4.2 Jelly Bean, thus allowing one to use all the latest apps. A 1.2GHz Dual Core processor paired with 512MB of RAM ensures crisp processing speed, even under moderate workloads.
Camera and Storage
The device comes with a 3.2MP rear camera that is capable of fulfilling the expectations of the shutterbugs. A 0.3MP front camera takes care of video chatting requirements. Internal storage is 512MB, which can be expanded using microSD card up to a limit of 32GB.
Connectivity and Battery
The device comes with sufficient connectivity options, including Dual SIM, 3G, Bluetooth, GPS (with A-GPS) and microUSB connectivity. A 1500mAh Li-ion battery takes care of the device's power requirements.
