Need a solid AOSP ROM (What is AOSP?) for your Galaxy Note 4 with Android 5.1.1 and root out of the box?
My current favorites include the Resurrection Remix ROM and the CrDroid ROM. Over my month long vacation, I got to test out the CrDroid ROM in Thailand and worked beautifully well for a great/fast AOSP experience. Of course, this is an AOSP ROM so if you use a lot of Samsung specific gadgets (like Gear S watch, S-View Cover), it’s probably not for you as you will lose those features. But if you absolutely need to be on the latest Android 5.1.1 with pure Google, CrDroid is a great choice.
