Looking to turn your Note 3 into a Note 4? Look nowhere further than Note 4 Port Evolution ROM by XDA user Kbythwood!
Based on Android 4.4.4 TouchWiz, Note 4 Port Evolution ROM brings you Note 4 system UI and features to your Note 3, it will work on the AT&T Galaxy Note 3 SM-N900A, T-Mobile Galaxy Note 3 SM-N900T, Canadian SM-N900W8, and (should work, although not tested) international SM-N9005.
Out of the box, the Note 4 Port Evolution ROM will bring you everything from Note 4, all except features that requires Note 4’s new hardware such as fingerprint/UV/heart sensor. Otherwise, this ROM pretty much turns your Note 3 into a Note 4 minus the higher 1440P resolution (who needs it anyways, it drains way too much battery).
If you don’t care for Note 4’s new Gear VR capability then this ROM will turn your phone into Note 4 without having to break your damn wallet! With this ROM, you will be able to easily inherit Note 4’s super capabilities like floating multi-windows (by dragging your finger from corner, see video for demo), Ultra Power Saving Mode, Download Booster, and much much more.
Also, this ROM comes with a modded Note 4 launcher that is even faster than the real Note 4 stock launcher and performance/battery life is excellent. For T-Mobile/international version, you will also be able to overclock easily to 2.726Ghz thanks to Lean kernel and get your performance up to par with a Note 4 (near 46,000 on Antutu).
