May have faulty charger or connection, have you ?
To a degree, this is a duplication, simply because there are so many threads/categories that it's easy to go wrong.
My tablet is a samsung galaxy tab 3. I think that maybe the charger is faulty as it cannot be relied to charge the tablet, either that or connections are less than perfect. I ensure the plug is snug in power source, and that the micro port is is the right way, so, is it the USB port that connects to power plug?
Has anyone else had issues with charges and charging?. Would it be better to buy a new charger?, idea's please.
