If you’re familiar with rooting and custom ROM’s, then I’m sure you’ve had your fair share of trying to find the right kernel to flash that coincides best with your phone and current ROM. Keep in mind that the best kernel is always up for grabs and I feel is just too subjective to definitively determine who makes the best kernel. Every phone is different, and every ROM (stock or not) is different. For me, the best that has worked for quite some time now on my Samsung Galaxy Nexus has been Trinity kernel created by XDA user Morfic. Trinity is currently available for the Nexus S, Nexus 7, (AT&T/TMO) Samsung Galaxy S III and the Galaxy Nexus.
If you’re not familiar with Trinity kernel, or if you’ve never used it, Trinity offers a kernel that’s optimized and enhanced for performance all while maintaining a great battery life. Morfic also offers several versions of his kernel all dependent to your liking, whether you want an overclocked CPU version or even an overclocked GPU version. Trinity also offers great colors for my Nexus’ SAMOLED screen. Upon first flash, you may notice a slight blu-ish hue to your Galaxy Nexus’ screen, but trust me, after a couple days you’ll get used to it and will never want to go back to stock colors.
