Karbonn Smart A66

The Karbonn Smart A66 is an entry-level smartphone that comes with basic features and functionalities. It runs on the Android v4.4 (KitKat) operating system and is powered by a 1.2 GHz dual-core processor, which provides smooth performance for everyday tasks.

With only 256 MB of RAM and 512 MB of internal memory, the Karbonn Smart A66 may struggle when running multiple apps or storing a large amount of data. However, the memory card slot allows for expansion up to 32 GB, providing additional storage space for photos, videos, and music.

The 3.5-inch color LCD screen has a resolution of 320 x 480 pixels, which may not offer the best viewing experience compared to higher-end smartphones. The pixel density is around 165 PPI, resulting in slightly pixelated images and text.

The main camera is 3 MP with an LED flash, while the selfie camera is only 0.3 MP. The device is powered by a 1100 mAh removable Li-ion battery, which may not provide long-lasting battery life.
