Android kernel is the most important software component in an Android device. Perhaps you may already know what is Android kernel and how it becomes important when an Andoird is beign operated. Literally, the kernel is explained as "a computer program that is the core of a computer's operating system, with complete control over everything in the system" in official sources. When it comes to practice in Android, it connects software to hardware and hardware to software standing on standard software configurations. As, example, the stock Android kernel has been configured to provide an equal stream of battery power to the device every time without considering its activity level. Likewise, lots of technical functions are controlled through the kernel of your Android
Connection Between Android Rooting And Android Kernel
All the Android smartphone are shipped with the stock Android kernel by default and it is operated based on standard software configurations. As mentioned above, it operates each and everything on your device especially related to the Android device performance and battery life. As you know, rooting allows you to access the system partion of your device and launch modding apps as a part of stock Android systems. In this case, you can change the standard configurations of your stock kernel using a kernel manager. Basically, you can change the kernel settings and increase or decrease device performances and battery life when needed
What Is Custom Recovery
The custom kernel is a modified kernel for Andoird smartphones and you can flash a compatible custom kernel on your device instead of the stock kernel and control it completely using kernel manager. Actually, a custom kernel with kernel manager is more useful than a kernel manager with stock kernel.
However, you must be informed that your device cannot accept the official Google updates without stock kernel since Google requires the stock kernel to apply them on your device
