got a free EVO 4g from a buddy. had a broken digitizer(front glass panel). so i picked one up on ebay from a reputable seller. installed it, put in a brand new battery, let it charge fully before turning on. go to turn it on and all goes well, except the bottom 1/2 inch is not responsive. it makes it really hard to unlock and actually use.

Now, i have not installed the digitizer adhesive yet, could that be the culprit? could i have got a bad digitizer?
the digitizer i bough has a 30 day warranty so i could return and hope to get a better one?

what would you do?

thanks!
