Use it along with an Apolo configurator ( free from Playstore ) which allows you to tweak the kernel ( I mean, choosing the "best" governor/Scheduler....we are several to recommend zzmove/noop or zzmovz/sio ) and boost sound ( which is great because this is a weak point in Samsung phones.
You'll be able to play with BLN or BLNWW to control yr notifications !!!
In my opinion, by far, the best...but I admit, I haven't tested them all
All the best
