Bests & Worsts Reviews from Amazon

I have a problem. The phone loses telephone connectivity, LTE and 3G. This never happened with any of my other phones. After I bought the Power I experienced the problem with telephone connectivity so I returned the phone and got another one. You see,,, I'm a sucker for battery life. That said, the 2d phone exhibits the same problem. I visited my carrier who swapped the SIM card. I wanted to rule out that the SIM card was causing the problem. No change. It's the phone. What to do? Oh yeah, by the way, the battery life is top notch and the phone does everything else well.
