[Galaxy Note 4 Android Development (Snapdragon)] Black Shade:
This is a great introduction for everyone who wants to use this ROM for the first time.

Coming from a TouchWiz based ROM, you'll appreciate a noticeable performance bump with all the benefits coming with any Nougat AOSP ROM. Since it's an AOSP ROM, you have to keep in mind that you won't be able to use all the TouchWiz apps and features, SPEN only works as a stylus and camera isn't that great - but this also depends on the app you want to use.

Performance and battery are pretty good by default, but you may consider flashing the other kernel. This ROM comes with Samsung kernel pre-installed, which is great for performance, but uses more battery and tends to overheat sometimes. Emotion kernel is great for battery and doesn't overheat nearly as much, but you may notice some framedrops in animations. You can configure them manually anyways, using the Kernel Adiutor app: both kernels come pre-rooted, so you can accurately balance all the parameters and get the experience you wish.

There aren't many known bugs, the most important issues have been solved in the past months, I've been using Resurrection Remix for almost 6 months now. Sometimes camera gets stuck when taking photos with flash, forcing you to reboot your device to fix it. I was talking about camera quality before, and I have a pretty good solution for this: just download HTC Camera 2 from APK Mirror (try the latest version, if it shows compatibility issues just uninstall it and look for an older version); this is the best app I've found so far and I'm really satisfied by the results. The other issue is related to Bluetooth: some users have reported issues when connecting to their car Bluetooth systems, keep this in mind as a possibility. Other than that you'll only find a couple glitches, like a couple toggles not working properly in settings. There may be some stability issues, for example my Google+ app force closes sometimes, but it's a bug related to Nougat itself rather than the ROM.

Since this is an AOSP ROM, there's a lot of stuff to play around with. You may start changing system sounds, boot animations and themes. Keep in mind that sometimes you may go too far and your device could end up in a bootloop, but don't worry about that: just go into TWRP and flash the ROM again, clear caches and you're done, system will boot and all your data will be there. System apps or mods you installed will be removed though. You may know that, but in case you or anyone else doesn't, I wanted to include this.

When first flashing this ROM, remember that you should change your /cache and /data partitions to F2FS, you can do that in TWRP (once at a time). This will give you better overall performance. When flashing a ROM without F2FS support they should be automatically converted back to ext4; in case this doesn't happen, you can do it manually once again.

The ROM comes with Magisk pre-installed, it's a RR team decision. Some people don't like it, and you can remove it. I won't tell you how, but you can look for tutorials yourself. If you want SuperSU back, don't use the Play Store version: instead, you should look for the latest .zip package on the Chainfire Google+ page and flash it from recovery. This ROM isn't able to pass the safetynet test yet, so you won't be able to download certain apps from Play Store, thanks Google.

I think that's all you need to know. I hope it helped you to get an overall idea about this ROM!
