Tech Lass's Verdict:

The Infinix Hot 4 is a moderately speced device whose specifications are neither disappointing nor so exciting. Other than its fingerprint scanner which Infinix must have gotten the hint to design the device with from the excitement of users by the one featured by the Hot S, this would've been just another upgraded device, but it isn't. The Hot 4 still offers good value for your money.
