this is my first time fixing or replacing a phone screen although im preety good at things like this, I ordered a replacemnt GLASS on ebay, which my lcd is fie just the glass was cracked, so I get it all taken apart, I heat it up to separate the broken glass off the plastic frame, and when i get it off I notice right away that my replacement screen is see through, like lass, and the broken one i just removed has a dark, square, thats like almost sort of greasy stuck to the broken glass still, that thing is not coming off, and that dark square is broken too from me taking the screen off, i thnk it might be the touchcreen sensor or something, so I didnt know about this, is any way to get that part only? Im not sure what to do now
