The Xiaomi Redmi Note 4 is here, continuing the company’s tradition of launching phones with good specifications at low price tags. The strategy has paid off spectacularly, as Xiaomi crossed the $1 billion revenue milestone in India last year. While the company’s vast product portfolio now includes fitness bands, earphones, air purifiers, power banks, and other devices, smartphones continue to be the stars, and the Redmi series - of which the Redmi Note 4 is the newest member - has been a key contributor to its success.
