Just some advice before you install the screen regarding the earphone grille/mesh at the top.
Something I experienced, was that the speaker grille did not end up being seated quite right when the phone display was stuck down. It is slightly bent, and the top edge is stuck out at a slight angle - it is quite sharp and does not take much to catch a finger on it, when the phone is out of a protective case.
I think this was because I laid the screen in, starting from the top and with it up at quite a steep angle, then working from top to bottom. I would suggest that when setting the new display within the device, that you align the bottom edge first instead.
I am not going to risk lifting the new display to try and re-seat this grille properly, the display cost me a bloody fortune (around 58% of the phone's original price) and I am not risking breaking it over something as minor as that.
nb. I definitely removed all the coloured plastic protective pieces before installing the new screen into the phone.
