If you've had the camera for only 3 months it should still be under warranty.
You should contact HP about getting it fixed or replaced.
I purchased an hp m22 digital camera about 3 months ago. It worked great until about a month ago when hte door became very hard to open and now it opens easily but when you lightly oush on the top of the door the bottom of it comes off of its track. Is there a way to fix this?
