Samsung S5 or S6
It seems only yesterday that we were in the apartment in Kissimmee and Claire's Samsung S6 phone wouldn't charge. Okay. A First World problem as the saying goes. It was just coming up to two years old. A bit of wiggling of the micro-USB cable had little or no effect. So we found a phone shop in Kissimmee Old Town. They had it for a few hours and determined that the charger slot and the motherboard had a problem. It would charge on the QI plates they had in-store. I googled and it apparently is a known but ignored by Samsung problem. With loads of forums and technology pages explaining the weakness. In the end she bought a rather expensive charger dock as the S6 charges through its body.... Finally at home I bought another one from eBay that worked as well but is flat. She then decided as her contract had run out to get a new phone and S6 was condemned to a life in a drawer. She now has One Plus 5 phone. Much better and still...
