Kernel Manager Diamond BETA is a free Android application developed by SimoneDev. It is a powerful kernel settings manager for rooted devices. The app allows users to control all the main aspects that regulate the operation of the kernel. With this app, users can manage CPU frequency, TCP algorithm, vibration intensity, FSYNC, Read Ahead Buffer Size, governor, scheduler, GPU frequency, voltage control, screen color management, low memory killer, and sysctl.

The app also provides additional features like a build.prop editor and an apps manager. Users can manually add controls that aren't natively available in the program across the screen "Custom Controls" (Other). It's important to note that the application is in BETA, so during its use, some dysfunctions may occur. Instead of leaving a one-star review, users are encouraged to send an email to the developer explaining the problem encountered.
