i am currently on my 3rd iPhone 7 in less than 6 months and it is virtually useless. I received this replacement phone b/c the first replacement phone they sent me (when original phone quit accepting charge) developed what they told me was an antenna malfunction. Straight out of the box this phone worked less than 50% of the time. I am now a few months in and it works less than 1% of the time. It reads " No service" when my wife's iPhone 6 works perfectly fine beside it. Our old iPad also works flawless in same area. While sitting on the mobile hotspot (iPad) it can not find any wifi networks, but all other devices in room can find it. Even when it has signal, which is almost always 1x, it will not perform task. Weather app can't update weather for weeks at a time. Text messages take hours, sometimes days to send single message. I will receive a bundle of missed calls and voice messages from many days all at once. People will call and phone will never ring or show missed call. Even while connected to high speed internet over wifi when brand new out of box it would not download/restore my 15 apps after 2 days of trying. It tried to download pandora for a solid month 24/7, never completed. This is the worst phone/service ever sold. I purchased a new phone that stopped accepting battery charge and as a warranty I have now been sent 2 useless phones. When a new phone stops working because of factory defect I should be sent another new phone to replace it, not a series previously returned defective devices each one worse than the last. Verizon has failed to supply me with a device that is even semi usable for 6 months, but their bill arrives on time every month for a service they are not providing. I am fed up!
