One of the most important elements of the Android operating system, and in general of all Linux developments, is the kernel. This is the core on which almost everything in Google's work depends. Therefore, it is essential to know what this component is for and, also, if it is possible to update it manually.
The kernel is the core of the operating system, since it is in charge of manage resources of the Android terminal that you have. An example of what we say is that this is in charge of communicating to the software and hardware (such as when an application is running). This, obviously, makes it clear that it clearly affects both the performance of a phone or tablet; in the options that they offer; and, in addition, it also directly influences the stability. Therefore, the quality of this depends a lot on whether the user experience is adequate.
Thus, it is clear that if the kernel of the operating system is updated with a new trusted revision, the improvements will be many (if the installation is done with a job that is not compatible or stable, problems arise immediately). In this way, companies they take care of themselves very much when it comes to advancing this element, and it's the independent developers who are experimenting the most here. We recommend being very prudent, since we are not talking about a component of minor importance precisely - but, not at all, you should be afraid.
Can the kernel be updated?
Well, the truth is that yes. And, this is possible because the kernel is independent of the operating system itself, so being modular makes it possible to perform a manual update. And, this is possible both with a new official version or one of the Custom that exist. Of course, it is extremely important that it is clear that the new kernel to use is fully compatible with the terminal - since, otherwise, it is possible that some options do not work or, simply, that the phone or tablet does not work.
Indicating a process for each Android device is somewhat complex and inefficient, but there is a tool that generally allows you to update this component: Universal KernelFlash. It can be downloaded from Google Play using the image that we leave behind this paragraph, and it is very important to be clear that it should only be used with compatible terminals:
The use is very simple: the kernel is downloaded (in bin, img or md5 format), it is copied to the root directory of the device and it is selected with the application. Once this is done, the installation proceeds. Then it restart the terminal in question and ... ready! Others Tutorials for the Google operating system can be found at this section de Android Ayuda.
