If you are looking for Note 7 ported ROM for the Galaxy Note 4 Exynos versions (models SM-N910C or SM-N910H), you are in luck as The HydROM gives you exactly that.
Based on latest Android 6.0.1 SM-N930F Note 7 firmware, The HydROM gives you cool Note 7 features like Note 7 UX UI, Note 7 S-Pen apps including new Note app, Screen Write, Smart Select GIF, Translate, and much more.
Multi-window has also been enabled for all apps meaning you can use all apps for multi-window, which makes this ROM better than a real Note 7. There’s also a 5-way reboot menu and the ROM is deodexed so you can easily install Xposed Marshmallow.
Now there are still some bugs to be worked out such as buggy bluetooth and fingerprint sensor but you should still be able to use it as daily driver.
Note, this is ONLY for Exynos-based Note 4 such as SM-N910C or SM-N910H, please DO NOT FLASH on Qualcomm-based Note 4 like SM-N910F or SM-N910T as you can brick your phone.
