Tried to do the tip that has been mentioned in this and other forums whereby a piece of paper/cardboard/credit card/etc. is placed behind the battery to improve screen response. Well, first tried with a piece of an old credit card..no luck...battery would not fit back in. Then, tried with a regular piece of paper folded in half (to increase thickness)...no luck...battery would not fit back in. Then, tried with a regular piece of paper (not folded)..no luck...battery would not fit back in. So, I guess my screen is pushing pretty hard (tight) against where the battery is housed.
