Most of the introductions of this post are copied from Sultanxda's CM13.0 post.

Custom kernels are not compatible with this ROM. I will NOT provide support if you install a custom kernel.

ROM features:

Based off latest generic LineageOS 15.1 sources (root access is NOT included)

OTA updates via built-in Updater

Configurable multi-color notification LED

Custom camera app with several manual controls and high-speed video recording with audio

Custom camera HAL made by Sultanxda featuring:

-4K UHD video recording

-High-speed video recording with audio at 60 FPS and 120 FPS for 720p, and 60 FPS for 1080p

-Consistent 30 FPS video recording in all lighting conditions

-Intelligent anti-shake algorithm (significantly reduces motion blur when capturing photos)

-Faster autofocus in low lighting conditions

-No stuttering in camera viewfinder

-Improved photo quality

-Photo capture up to 4208x3120 resolution (instead of 4160x3120)

Many other misc. improvements under the hood

Kernel features:

Based off latest CAF Marshmallow kernel source from Qualcomm (LA.BF.1.1.3_rb1.13)

Removed lots of excessive bloat

Dynamic CPU input boost driver I wrote myself (makes the phone feel smooth without destroying battery life)

CPU underclocked to 1958 MHz by default (you can disable this; see why I did this in the FAQ in the 3rd post)

Custom thermal control driver I wrote myself (features 8 thermal throttle steps; keeps the phone cool)

LCD KCAL by Savoca

Westwood TCP congestion algorithm (enabled by default)

exFAT support

NTFS support

No placebo patches, features, or compiler "optimizations"

Many other misc. improvements not listed here

Installation instructions (for first-time installation):

First, perform a backup of your existing setup, and then perform a clean install (wipe /data and /system; TWRP is recommended).

Then, flash the ROM, flash a Google apps package, Magisk if you want root access, and then reboot.

Installation instructions (for updating to a newer release):

If you are already running my LOS 15.1 ROM, then you can update to a newer version of the ROM via the built-in OTA updater or by simply dirty-flashing the new ROM build without wiping anything.

FAQ:

1. What's the difference between this ROM and LineageOS?

They are almost same thing. I only added pixel navbar, pixel audio and custom qs tile to my ROM.

2. Custom kernel? OSS camera?

This ROM is fully based on Sultan's cm-13.0, I will not replay any custom kernel or OSS camera request.
