If you are looking for a good custom ROM based on Galaxy Note 5 firmware with S7 Edge panels, definitely check out Family ROM.
Based on SM-N920C international firmware, Family ROM comes with subtle features you may like if you want to keep the stability of stock ROM while getting some cool features like call recording, rounded notifications/recents, all apps enabled for multi-window, multi reboot menu, Viper4Android/Dolby Atmos, AdAway, and more.
As for performance, you can use GoogyMax kernel if using on international Note 5 and modified stock kernel for T-Mobile/Canadian variants, both which seemed to work well along with excellent battery life. (I was getting about 85,000 on Antutu.)
The UI has been tweaked to run much faster so you will notice slight improvement with that too. And there’s ambient display (not Always On Display) add-on zip you can flash.
Overall, this is an excellent custom ROM for those of you who want stability of stock firmware with tweaks to make your Note 5 better so definitely give it a test drive this week(end) and do let me know what you think!

First, boot into TWRP, make a backup ROM (if you want to restore ROM if something goes wrong), then wipe system, wipe, install ROM, install add-ons, install kernel/data fix, and reboot. That’s it! Don’t know how to do this? See our fail-proof TWRP installation guide first.
