Xiaomi has recently unveiled the advancements in optimizing its Pengpai OS system, encompassing models like the Xiaomi 15, Xiaomi 14 Pro, and REDMI K80 Pro. Among the issues resolved are delays in swipe-up gestures within applications, crashes in the camera's professional mode, and the inability to activate the voice assistant using gesture hint lines. Ongoing challenges include the inability to trigger the storage refresh function, difficulties in switching to dark mode, and the persistent display of the floating ball even after it has been turned off. Xiaomi is diligently working on further system optimizations to enhance the overall user experience.
