Karbonn X21

Karbonn has failed to build on its early promise in the Indian market. The company found it hard to compete with Chinese brands that offer quality hardware at low prices. But now it wants to focus on upgrading its lineup with 4G budget devices like the X21. This phone comes with a 6.1-inch HD+ display with support for 720x1440 pixels resolution. The screen features thick bezels and offers pixel density of 264 PPI. The Karbonn phone packs octa-core chipset that comes paired with basic 2GB RAM and offers 16GB storage that is expandable up to 128GB using the dedicated card slot. The X21 features a single 8MP rear camera and on the front, it has 5MP selfie camera. The phone comes loaded with a 3000mAh battery that supports charging via microUSB port. Other features on the phone are rear-mounted fingerprint sensor, face unlock and headphone jack. Other Karbonn mobiles you can consider are K9 Smart Eco, Platinum P9 Pro and the Aura Power 4G Plus.
