[Q] How to have note4 features on my s3 4.3? topic

Hi all, i'm using a different ver of s3 SHW-M440S. I've thought of have note4 UI and features on it but it seem to be impossible when i found out that note4 roms for s3 don't support my phone, it only supports gt-i9300 and people said that trying to install may brick my phone. Next i trying to have note 4 app but it only for 4.4 :( yesterday i install note 3 secphone.apk by replacing the original one in sys/app but i found that there wasn't any secphone.apk but secphone_KOR.apk. i backup it, paste secphone.apk and renamed it into the same as ori one, set permission and reboot. When it turned on again, i call a friend and it said ... has stopped. i backup it and it worked so i could have note3 call features :mad: All thing i can do now is root it. Does anyone know how to have note4 features on my s3 4.3???
Thank a lot :rolleyes:
