A bit of concern to ask.
My C905 have a bit of "defect"? The sliding screen section is kind of not so well assembly. Hmmm how to put this out. Well, is just that the main screen section are off balance and when you press on the "end call button" the section will kind of like sink down and once you release the button, the whole section will pop up.

Well, if some one understand what I mean, perhaps you can help me illustrate better or does every C905 user facing the same problem

hello guys, newbie here 
mind if i ask 2 questions?

i might be getting this phone soon. can any1 enlighten me what's the disadvantages of getting this phone?

if the sound system ok? 

See that u bought ur C905 already.. congratz..~ hehe.. Sold mine already.. haha.. dun really like slider phones but still a great phone to use.

Moving on to Xperia..~

After using it for 4 days, the gap at the top of my phone (between the slider and the phone) become
wider..and it cause the 'see-saw' effect slightly as mentioned by sumone in this thread..
and i think the warranty could not do anythin about this aite?
