I received a refurbished phone and the first one would shut off and reboot after I write a text...hit send ....and close slider while message is sending....never did it with first one...went to verizon store..it did it to him too...got another refurbished phone...worked fine the first night..when I customized it...it does the same thing...have compared my phone settings with hubby's phone and his is fine..mine..is doing it ...and I am going nuts! What am I doing wrong?
