Is Sony Ericsson k800i's camera cover slide little loose?

I have recently purchased (2 days ago) a Sony Ericsson K800i and found some small problems with it, which I didn't expect from this phone. Being my first sony ericsson phone can someone answer these questions?

1. Does the camera cover slider have a little movement when it is closed? I mean, when I touch it, I feel that it is slightly loose. If it doesn't happen normally, I will have to take it back to the shop.
2. Does K800i hang rarely? One day when I returned from one screen to another, the last view got stuck a little bit and I had to restart the phone to get rid of it. Second time it hung when I searched for bluetooth devices.
3. Is the sound quality moderate? When I played music, I could hardly hear the voice when the sound level was on 4. Comparing to my Nokia N80 the sound quality is on very low level and being a Sony Ericsson, which are well known for its sound quality.

1. No movement at all on mine.

2. Depends on what firmware version you have, but some can die - mine used to do so when sending particular files by bluetooth.

3. Nope, sound quality is great, but it does depend on what headset you're using. If you're using the one included in the box, then you wont get much out of it.

I've been looking at the k800i recently because I'm after a decent camera phone for when I go round town with my mates to get some good pics for when I go to uni.

When looking at reviews for the k800i i would say that the sliding cover is a problem for many. A friend has the phone and I was askin him about it the other week and he said it drove him crazy but the other than that he loves the phone.
