Since 2 last versions the speed of wifi 5Ghz is very slow.
With previous roms the speed was good, but now with the same router is very slow. With other phones the speed is goodm
Every time i reboot the phone (Mi9), the "notification access" grants don't work. I have to disable an re-enable the grants to work again.
In my case, is for aevery application, for example "Mi Fit" application to notify on my Amazfit Bip.
