Through these kernel source codes,DevelopmentPersonnel can create custom ROMs for these devices on the basis of Android Open Source Project (AOSP). In addition, since Android Pie for LG G7 ThinQ and Red Note 6 Pro has not yet been released, the appearance of the source code indicates that the two devices will be upgraded soon.
For developers who don't like all kinds of pre-installed apps and prefer a purer Android experience, this can help them create custom ROMs that are more in line with their own tastes. Kernel source code is a bridge between the specified hardware communication in the operating system and devices, so the kernel sources of different devices are different, and they are not interchangeable if the underlying hardware is different. Since the kernel is developed under a general public license, OEM changes need to be shared among the community to help advance the open source community.
