First of all allow us to congratulate you on such a wonderful purchase. Since we've had versions 2, 3 and 4 of the Samsung Note, we can only tell marvels of this piece of computing device. (Yes, we don't think its a phone).
For starters and to answer your question and I must say that we do not condone breaking your phones warranty so the information enclosed herein is merely from an academical point of view: rooting your phone.
Rooting your phone is the very first step to allow for your Note 4 to use its vast amount of features and attributes.
After you've rooted your phone the next step is to get rid of them back-end applicaitons which truly do nothing for the user suck as Knox, Printing and monitoring apps. You can do an analisis online to detrmine what suits you best but bottom line is, most of apps that come with the phone are useless and must be removed to make room for speed and system resource management.
After you've removed pretty much as the "pain in the neck" apps make sure you download tools to keep your phones performance optimized. Additionally install a free antivirus and a version checker que make sure your phones software is up to date.
Then and only then proceed to install and remove the apps you like and hate.
