In this seven month i have faced problem regarding phone heating and second time mike problem .First time job no is w[protected].And second one is w[protected].I have paid this much of money but i am not satisfy with the phone as well as service station's service . My phone has been send to company for 15 to 20 days. As per service station policy they are giving stand by phone.But they didnot given me stand by phone as well .So give me suggestion what will i do without phone after purchasing costly phone? when i have purchased this mobile, i have two other options one is lg g2 and samsung galaxy s4 . I have selected sony for the best company as well as service .But sony disappoint me.
