This phone has merits such as good touch screen, colour depth is good, good ringtones then previous dual sim 3.2mp d880, direct acces to communities like google, tweeter, e.t.c (which in my case of no use). But its demerits are also prominent, as i am old user of dual sim like d880, trend d786i. b5722 demerits are:1 At taking photo when flash light is on then photo taken is only light no photo or very poor image, its mean this mobile has no ISO control, more over in d880 there is auto focus while in b5722 ther is no autofocus which needs more experties while taking photo. 2; No auto ke lock function only manual ontouch keylock button. 3; Creating a playlist is almost impossible for listining music, because there is no option to go at folder level for slecting the songs of ur choice. 4; on internet side large pages cannot be open in its browser. large files or java sw cannot (more than 10mb) be downloded. 5; to open battery cover is much tricky and difficult
6;During sms writing symbols option and numeric option is not on same screen but rather u have to go further two steps more in options menu, for geting a single symbol like /,@,? e.t.c.
7; no qewatery keys.
