I currently have a Samsung Galaxy Note II (GT-N7105) which is not rooted and is running 4.4.2 Kitkat, while it still works pretty fast, sometimes if just freezes with all the processes.
I have though about rooting it so i can delete all the applications that might be using hidden processes and storage room but i have read that rooting it could also cause major problems if done incorrectly so i was looking for another way to delete these applications (Samsung Push Service, etc.) without rooting it, and if there is none can someone direct me to an almost fool-proof way to root it with Android 6.0 (or another, doesn't really matter).
