LG MM-535

I really enjoy this phone other than the battery life. Of course, everybody who sees my phone wants to try to flip it the freak open. A few tried a little too hard. I was wondering if anybody has experienced a bit of a wiggle with the upper half. There is also about millimeter gap between the two halves if I try to flip it open like the other morons did who wanted to check it out. 😕 I just want to know if this is normal with use or due to the systematic flippers. Thanks a bunch guys.
