Two out of two 6.1 Plus having charging problems. The problem seems to be widespread.
The reason is definitely a weak USB port that cannot stand standard use. After a few weeks or months, no way how careful and gentle you are trying to be when plugging in the charger end, the USB port on the phone will become loose. I see no reason to send the phone for weeks of repair under warranty, if the design of the board is the same.
NOKIA, please consider to test how strong or weak the USB port on the 6.1 Plus is, and consider to recall the product, or at least to make available a new improved version of the USB charging board for durable replacement.
NOKIA has always been famous for its reliable hardware, hope this will improve on Android phones too, or should we all go back to other brands?
