Maybe because:

----[ command 'luvcview -L' ]-------------------------------------------
luvcview 0.2.4

SDL information:
  Video driver: x11
  A window manager is available
Device information:
  Device path:  /dev/video0
/dev/video0 does not support read i/o
{ pixelformat = 'MJPG', description = 'MJPEG' }
{ discrete: width = 160, height = 120 }
        Time interval between frame: {min { 1/20 } .. max { 1/20 } / stepsize { 1/10000000 } },
{ discrete: width = 320, height = 240 }
        Time interval between frame: {min { 1/20 } .. max { 1/20 } / stepsize { 1/10000000 } },
------------------------------------------------------------------------

and /dev/video0 is created, if I connect the Webcom.

And on the website is is written:

    0e8d:0004  	MediaTek MT6227 phone  	MediaTek Inc

but my Longsun L580 Dual-SIM/Dual-StandBy cellphone has the MT6225 chip
