For those of you who have a BlackBerry Storm (1), you might notice that the screen clicks really well in some places, and somehow the corners don't click really well at all. You sometimes need to really press hard to get it to respond, etc.
I found a little trick out to make it click perfectly!
Remove your battery and tear up four small pieces of paper (a little smaller in size than your battery) put those pieces of paper underneath your battery. It should work perfectly! (If not, try adjusting how many pieces of paper you use.)
