Xiaomi announced the latest iteration of its proprietary Android skin, MIUI 12 in China back in April this year. Which was followed by a global announcement in May. Though the MIUI version upgrade brings various new features and updated UI, the company keeps adding nifty features with updates every now and then. A new feature that has recently made it to the MIUI 12 Global Stable is the ability to adjust the sound for individual apps when multiple apps play audio simultaneously, instead of adjusting the entire system volume.
