EX Kernel Manager (EXKM) is the ultimate root tool for backup and flashing kernels, tweaking color, sound, gestures and other kernel settings. EXKM gives you total control over your hardware with premium features and a simple and modern user interface. Your device must be ROOTED to fully use this app. This app works with ALL devices and kernels. ElementalX is not required. Some advanced features such as wake gestures, color and sound control require a compatible custom kernel. Dashboard: your homepage within the app, Dashboard summarizes your current settings and shows real-time CPU and GPU frequencies, temperatures, memory usage, uptime, deep sleep, battery level and temperature, governors, and i/o settings. Battery Monitor: the most accurate way to measure battery life. EXKM's Battery Monitor is designed to show battery statistics that you can use to optimize battery life scientifically. EXKM Battery Monitor measures % battery use per hour and gives separate statistics for screen off (idle drain) and screen on (active drain). It automatically measures only when the battery is discharging so you never have to remember to reset the stats or create markers. Script Manager: easily create, share, edit, execute and test shell scripts (requires SuperSU or Magisk). Flash and Backup: save and restore kernel and recovery backups, flash any boot.img, recovery zip, Magisk module or AnyKernel zip. Import custom kernel JSON configs. CPU Settings: easily create, share and load CPU governor profiles for maximum battery life. Adjust max frequency, min frequency, CPU governor, CPU boost, hotplugging, thermals and voltage (if supported by kernel/hardware). Graphics Settings: Max frequency, min frequency, GPU governor and more. Advanced Color Control: RGB controls, saturation, value, contrast, hue and K-Lapse. Save, load and share custom profiles.

Custom User Settings: This feature allows you to add any kernel setting you want. Kernel settings are located in the /proc and /sys directories. Navigate to the desired path and quickly and easily add the setting to the app where it can be changed on the fly or applied at boot. Plus you can easily import/export your custom settings and share with other users. Memory Settings: adjust zRAM, KSM, lowmemorykiller, and virtual memory settings. Sound Control: adjust speaker, headphone and mic gain. Supports elementalx, fauxsound, franco sound control, and others (requires kernel support).
