I have complained about this to the distributor I have purchased but they are not responding... I have Also call to ur customer care number but they are not responding also... We are also thinking to purchase iPhone 7 but watching the issues in this phone we are having doubt to purchase... I think I have waste my money in purchasing ur Apple phone... As ur customer care are also not responding...
