Hi. After a week of using this here are a few things I have in mind :

1. New update is awesome. Smooth and etc.
2. I really need a screen protector and casing since I almost literally drop it this morning. Will visit The Mines tomorrow and buy anything I find first for my trip balik raya this weekend and only change to a better one later.
3. Battery wise I consider OK.

I have a question tho, say I charge from 59% to 90% and then unplug it or from 11% to 50% and then unplug it, this habit will surely damage my battery faster right ? But, it will not affected other hardware right ?

My experience from my last few phones were using allright without a sp.. this time i bought a note 3.. the screen is perfect.. seems like got finger print proof..not much finger prints or not obvious from my screen.. very smooth sliding, touching..

But..after i applied a sp on it.. it isnt as smooth as before..colorwise still nice..not washed out..so..u may hav to reconsider on sp..mine one hav many finger prints on my sp..so obvious...

Only sand particles can scratch your phone
Normal metallic stuffs eg coins, keys will not. I even tested dragging lightly  a scissor, screwdriver n pen blade across display n it turns out well.
My chance of display scratch is near zero as it is always protected by flip case cover.
In fact I will try as far as possible not to use SP n my gadgets has always been scratch free. Only the Xperia range I put SP due to anti shatter film is not scratch proof.

Long no people bring up "Ahem", I nearly forgotten already. Haha!

and YES! it is advisable use original. Stop Piracy!
