Comparisons Featuring Karbonn A4
Short Review
- The Karbonn A4 features a compact design with dimensions of 124.8 x 66 x 9.5 mm and a lightweight build at 75g, available in white and black colors.
- Its 4.0-inch TFT display offers a resolution of 320 x 480 pixels, resulting in a pixel density of approximately 144 ppi, which may not provide the sharpest visuals.
- Performance is limited with 256MB of RAM and 512MB of internal storage, suitable for basic tasks but not demanding applications.
- The rear camera is 3.15 MP, capable of video recording, but lacks advanced features like optical image stabilization.
- Battery capacity stands at 1400 mAh, which may require frequent charging for extended use.
- The device runs on Android 2.3.6 (Gingerbread), an outdated operating system that limits access to modern apps and features.
- Connectivity options include Wi-Fi 802.11 b/g/n and Bluetooth, but it does not support 5G or NFC.
- There is a headphone jack for audio output, but stereo speakers are absent.
- Overall, the Karbonn A4 is a basic smartphone suitable for simple tasks and calls.
- Its specifications reflect its release in 2013, making it less competitive in today's market.
