So my gf accidentally launched my tablet off the bed and the screen cracked straight from one side to the other. The display is intact, but the "touch" screen does not work on one side of the crack, and the thing doesn't put itself to sleep anymore. Would all symptoms be a result of the cracked screen? I've been google researching fixing this thing and it seems like Microsoft will charge you the cost of the thing to fix it, or I can order a screen on ebay and fix it myself. Anyone done this? Is it easy enough to do?
