This will be my second time my phone shut off on me. First, I bought my phone this March of 2014, I had it sent in May 6, because it just turned off and would not turn back on, ZTE fixed it, yet never told me what was the actual problem. and my phone was not dead, it was actually 80%.I put my phone on the car charger, then once I got to my destination which was about 10min. my phone would not turn on. Fast forward to today June 4, my phone was fine from 10-4pm.On my way to my second job,my phone was going dead, so I put it(phone) on the charger along with the GPS on.My phone was working ok with a signal lost,at times but for the most part it was working properly.All of a sudden, I didn't hear my phone speaking so I checked,and notice it would not turn on. LED light did not come on.So my first intentions is that it was the battery since my phone was dead.But what I do know is that once I plug my phone up to a charger,The LED light, signals on.yet that didn't happen, so I kept it charged for a while like 10-20 min, and checked it again, no response. So I did a technique ZTE repair customer advisor asked me to do, which was hold the power, and bottom volume key at the same time,I did that and it didn't work.The first time I sent it in, they didn't charge(bill) me since my phone is still under manufacturer warranty . I really need your help please and thank you. Ps. I have a ZTE Max 950 (boost mobile).
