Help battery cover doesnt fit

[gt33]

The left lower side of my battery cover doesn't fully snap into place, causing an annoying gap. It was never like this, but I took the cover off to remove the battery, and when I tried to put it back in, it wouldn't snap. I tried a different cover and it still didn't fit... I have no idea why it wont snap in all of a sudden. Anyone else have this? I'm on my fourth epic, If I have to go to #5 I might just say forget it and save my upgrade

4 epics with the same gap issue out-of-box, that's hard to believe.

the others had different issues, I swapped it out today for a new one

Push it in harder. (the back that is)
The battery ive discovered that you have to get in in perfectly before it wants to get inside
