As much as I love the Droid, I am extremely disappointed with the battery hatch which is cheap, flimsy and KEEPS SLIPPING OUT!!!
mape I don't have any problems with my battery door so I'm not sure if this fix actually works.
but bend all the metal tabs on the battery door slightly inward.
It MAY secure the door down a little better.
mine came off a couple of times so i tried what someone suggested i a previous thread, which was to cut a buissness card to fit inside the cover. this forces the cover out a tiny bit more. so far so good.
The battery cover is neither cheap nor flimsy, but it does have a tendecy to 'come loose'.
I solved this problem by bending the attatchement hooks out a few degrees with Vice Grips (tm).
... of course better engineering could have solved the issue entirely, but it is what it is at this point, and hardly a 'deal breaker' - IMO
