Its easier than I initially expected. I just followed the advice the seller gave me. Use torch light to shine from side of phone (any side) to see if got any dust stuck on screen.

First align SP to phone to see how it should fit, wipe screen with alcohol swab (provided), then with microfibre cloth. Check to make sure screen is clean (if not clean, repeat), else, align SP and place on phone. Press from one end of phone to the other end (squeegee not really necessary also). Finish and enjoy!

err... One thing tough. You might want to stick the jellybean button first. I stuck it on after kau tim the SP and found it a bit hard to align.

Hope this helps. 

if u normally did stick film SP then should not have any problem

try with bottom up stick. mean start from home buttom.

before remove the sticker try to allign first to estimate.

switch off ur fan and aircon. it work just fine for me with above step.

My glass sp is similar to the 1st one and it is 0.4mm. The button is not really deep sunken and I didn't use any aluminium or jelly bean button. It is almost flush with the sp. But I hardly use my home button as I use swipe and gesture. I only touch the home button when I need to reboot to recovery or download mode manually.

once you root you lose OTA because system sudah CUSTOM instead of OFFICIAL

flashing updates is as easy as

1. go to play store (kedai main)
2. download mobile odin pro and pay for it (muat turun odin pro mudah alih lalu bayar)
3. go to sammobile and download whatever you want (pergi mudahalihsam)
4. flash through MOP (sinar melalui MOP (bukan mop lantai))
5. knox still 0x0 (ketuk masih 0x0)

used quite long and quite a few versions

i lose OTA every single time

OTA means pushed to you, usually it won't be pushed also / failed at installation

because he wash, didn't wipe.

must wipe, extra clean mar
u test then you let me know

i talk how much saliva also no use if you don't belip me

go flash then we talk

That wugfresh kit is only relevant to Nexus devices. Samsung if rooted cannot be update through OTA based on my experienced having used most of galaxy, Note series of phones.
