If a person loses some mass from his arm, it might go unnoticed. A drop in volume of thigh muscle, too, perhaps remains invisible. The disappearance of chubby cheeks might still not turn heads either. But when the tummy gets sucked in, it catches instant attention. That’s the story of Xiaomi, India’s biggest smartphone player, which has seen back-to-back dip in its quarterly market share for the first time in over five years. From a high of 21 percent in the first quarter of 2022, the share has slumped to 16 percent in the corresponding quarter of this year, pushing the Chinese giant out of the top in the pecking order and relegating it to fourth position behind Vivo, Oppo and Samsung, according to the latest data released by Canalys.
