The verdict, up front

Borrowed flourishes, floor price.

Spark 40C dresses an entry phone in big-phone flourishes — a 120 Hz panel, a dynamic-island status pill, stereo sound — for around $100. The Unisoc chip, HD+ panel and ad-heavy HiOS are the unavoidable cost. As a flashy first phone for emerging markets, it does its one job.
