In a Mi4w, after installation of the latest 6.1.21 and following the sequence provided i found the following bugs:
-No root acces, althought the menu says I do. I my applications needing root access, as Greenify, Titanium Backup, are not working
-In advance properties of WLAN, the option for optimization of the connection is not there any more.
-The option Keep my WLAN on during sleep, only when plugged in, not working neither.
-I have the feeling that the battery drains faster
Thanks for all.
Root solution when?
