1. Prices in Bangladesh (2025)

The Xiaomi MIX Fold 4 price in Bangladesh places it at the high end of the smartphone spectrum—but still undercuts many flagship foldables:

6. Display

The highlight of the Xiaomi MIX Fold 4 is its dual-screen design:

1. Cover Display: 6.3-inch AMOLED, 120 Hz refresh rate, excellent brightness for outdoor use
