Hello, im a happy s4 mini user in 2019. Running latest stock rom, rooted. I want to get every last ounce of power out of this awesome device. Since i dont plan to get custom rom, i decided maybe i should at least get custom kernel. Mostly for overclocking but if there are other goodies included im up for it. I need help choosing the right one and basicly what is the simplest way to install it ? If possible i would like everything on my phone to remain as it is, meaning no deleting apps, factory reset and others. Is it possible ?
