Karbonn A40 4G Details

In a bid to compete with Reliance Jio's dominance over the 4G and budget 4G smartphone market, Bharati Airtel announced the release of a new smartphone manufactured by budget phone manufacturer Karbonn. The Karbonn A40 4G is a modified version of the earlier Karbonn A40 smartphone, with 4G compatibility being its most notable upgrade.
Display and Camera
The Karbonn A40 4G features a 4-inch IPS LCD panel with a resolution of 400x800. It has a dismal 5-megapixel primary camera and an equally disappointing 0.3-megapixels secondary camera. Both cameras lack flash, and their daytime performance is worse than the low light performance of some devices. As this is a budget phone, the cameras have been scaled down to offer only the essentials regarding photography and video calling prowess.
Hardware and Software
The Karbonn A40 4G features a quad-core processor clocked at 1.3GHz along with 1GB of RAM and 8GB of internal storage which can be expanded up to 32GB via microSD expansion. The battery is an underwhelming 1,400mAh Li-ion unit which will be hard-pressed to run even half a day. At the least, it can be used as a portable multimedia player that also offers internet and phone call functionality. Other than that, running even commonly used apps such as Facebook and Messenger will be a chore, given the underpowered processor and low amount of RAM on the device, which in turn makes gaming and multitasking near impossible. The device is expected to run Android Nougat 7.0 out of the box. We're not sure how well it will perform, as it is resource-heavy.
Connectivity and Additional Features
The Karbonn A40 4G is a dual SIM phone and compatible with 4G and VoLTE, as the name suggests. Other connectivity features include 802.11 b/g/n WiFi, Bluetooth, GPS and a micro USB port for charging and data transfer. Other than its low price, nothing really stands out about the device.
