Introduction

Custom kernels - kernels that's modified by devs to include more features, I guess? yeah, I guess that's that. For the kernel themselves, it's the program with complete control over the system.

How to flash a custom kernel

This guide is for PDAs with TWRP (or any TWRP-based recoveries), and it assumes that you've started from a fresh ROM installation.

Else, if you don't have TWRP and/or a way out in case of issues; or if you don't need to use one, don't bother flashing.

Features

These are some of the features (or anti-features) that may be gained by flashing a custom kernel.

Recommendations

Generally, the availability of custom kernels wildly vary among devices, so use whichever you want (or don't flash any kernel if you're fine with stock kernel / don't want any more issues). Having any kind of overclocking seems cool on paper, but you should avoid it, especially if you want to have a longer lasting PDA.

For kernel managers, the only real option is Smartpack. Kernel Adiutor is no longer updated, FK Manager & EX Kernel manager requires total submission to Goolag botnet and should be avoided.

For some devices like the Zenfone 6, you should ensure that the required firmware version matches the firmware currently installed in your PDA.

If you don't trust other kernel devs, you can always make your own custom kernel. This way, you have control over the kernel development.

Kernel tweakers

You don't need a kernel tweaker for anything, whether it's enjoying whatever benefits the kernel you're using, or getting better benchmark results. If you really must use one, at least be on the stock kernel.

Avoid

If you want your display to last, you should avoid kernels with display overclocking enabled. However, if they have a variant without display OC, it's fine to use (the non OC one).

An example of kernels to avoid (for the F1) is LawRun. In addition to the reddit thread below, I'd like to add a few extra reasons : Source code & GitHub releases hasn't been updated & the only place to obtain the latest build are ad-ridden sites.

Reddit thread for LawRun (old):

Also, here are more lists of what kind of kernel you should avoid :
