Hi. I’m Sohanur Rahman Sobuz. I’m CEO/Founder of DroidBuzzz™. I actually created this blog for Symphony W72 User cause there is No Custom Rom for it. Thats Why I started Porting Custom ROM and Publish here. In the Meantime many Visitors have come to my blog thats why I publish other phone's rom too. Actually I am not a Dev.
