Franco Kernel Manager works for ALL devices and kernels.
You need to be ROOTED for all features besides Battery Monitor which works rootless.

Franco Kernel Manager makes use of the AccessibilityService allowing us to detect the activity displayed in the window. As as example, when this service is enabled and running whenever you open an app we are alerted through the api the visible window state is changed, and we can infer the activity's package name and thus checking if we have a profile for said package and apply it. No data is collected/stored/logged through this process.

Crashes on Pixel 8 Pro. No way to even start the app unfortunately. Edit: The developer has fixed the issue and the app works as I've always known it for years now, still every bit as great as ever! Love the functionality and granularity of everything it lets me do. Absolutely recommend.

has some occasional bugs like live performance monitor not showing. also, one thing that's really annoying is that the values keep resetting whenever i restart. even if i applied it on boot. settings on boot aren't applied on boot.

Working great so far, my only complain is that it would be nice if updates were more commons. Before the november update, fkm hasn't been updated in 2 and a half year (march 2021), which is kind of odd for a paid app.
