The taook the mobile and verified for about half an hour and told that there only software problem and the Phone will be ready by 3/04/2017 Forenoon. Now i am going to show room every day and they are telling not yet ready .We need permission from the company for change of soft ware will be done in two days. Now it is already friday (7/04/2017)and now they are telling that still they have not received approval from the company for update of software and may be the instrument will be ready by Monday(10/04/2017)
