It is not frozen and that is not nearly the only issue with this new phone. When I get calls and people leave voice messages, there is no notification of the message. The only way I can get messages is to hold down the number 1 and wait for voice mail to come up. The phone doesn't turn off except for a restart using the assist mode. I hate that mode having that floating ball always in my way. The phone issue was on my iphone 6S and was why I was told I needed to get a new phone, but I have the same issue here. Nothing has been resolved except I am now paying monthly for a new phone. Frustrated.
