Small black bar in display as shown in the photo. The black bar is not expandable, seeing this for more than six months without further expansion. Slide lock/unlock and slide-to-music works perfectly. How it is different from initial N95: a. Symbian OS which Nokia used to use is expired a long ago. So, there is no software or security update. This restriction has made internet browser and other internet related applications unusable. b. Unlike in initial models, camera lens does not rotate.
