I just successfully replaced the front glass of my 3th Gen iPad WiFi, but when I cleaned up my desk, I found out I forget to use the 4 LCD screws:

Is it worth it working another hour to open up the iPad again and place those screws in place? Or are the adhesives strong enough to keep the LCD in place?

It happened the same thing to me, what did you do finally? It was so critical? I really don't want to disassembly it again, I don't want to crack the screen... Thank you! – user43673 Feb 24 '13 at 12:28
If they weren't strictly necessary, Apple wouldn't put them there... – EmmEff Feb 24 '13 at 16:17
@Jordi, I did reassemble the iPad... The answer of bmike convinced me to do so... – Michiel Feb 25 '13 at 7:26

Go back in unless you are worried you will break it the second entry.

Adhesives won't hold under vibration and shock like a screw will and the screw pressure is what helps set the adhesive in the first place.

I realize it may be better to reopen the unit and replace the screws, but I still have the first iPad 2 I replaced the screen on and I completely misplaced my LCD screws. I just decided to put pressure on the back of the unit to hold the adhesive to both the covered glass and unit.

I've found over the last few years in the dusty environment of my farming community that it works just great anywhere. However I can understand that you may not want the LCD placing any pressure on the backside of the new digitizer.

If you are proficient at getting back in the unit I'd try to put them where they belong but mine works just great the way it is without the corner support screws.
