When I use my k20Pro ，it will be frozen in several day.Then，I can ony force to reboot it.Both the miui11 develop and stable version have this problem。
How can I solve it？
My Surface Go doesn't have internet with hotspot on my K20Pro.
But my redmi note4 pro can use internet with hotspot on my K20Pro.
My system version is MIUI 11.1 9.12.12.
Also,It's no problem on the MIUI 10
