I need an answer how to fix it
Unable to activate battery perfomance mode in Flyme UI 6.0
do you have the security app in flyme ui 6.0??
do you have root??
if you have root you are able to download battery performance app from playstore
such as CPU tuner (Rooted phones)
yes i have the security app and i have rooted the phone.but is the security app the problem?
