If you are looking for stability of stock Note 5 firmware but with S7 Edge panels and a few tweaks, you may want to check out the latest Viper ROM MM w/ S7 Edge Panels.
Based on latest N920C Android 6.0.1 firmware, the Viper ROM brings you full S7 Edge panels and fully deodexed ROM so you can easily install Xposed installer and modules. For root, you will get SuperSU and the ROM comes with speed meter for monitoring your internet data, camera enabled during call, call recording, rounded recents, pop-up notifications, and some more.
There not a whole lot of customization on this ROM but it is very de-bloated and speedy performance also give you very good battery life. And yes, for those of you looking for private mode working, this ROM has it working out of the box. So, definitely give this ROM a go if it’s your cup of tea and do let me know!
Note: This ROM can be installed on all international models including the SM-N920C, SM-N920G, SM-N920I, along with T-Mobile SM-N920T and Canadian SM-N920W8. For T-Mobile, you will lose WiFi calling since this is a ROM based on international model.
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.
