Yes.
OK, very honest speaking. It is so invisible that I cannot judge if it is already applied or not.
So, I went applied two layers. GG.

Now my screen is still responsive but may not be as smooth as the time I bought.
Still, I still can swipe my screen happily la.
So, lesson learnt. 1 even layer is enough.

Now waiting for it to wear off over the time.
