Thank you so much!! I would never have looked down there! Hopefully that will solve everything.
Hopefully I will figure out how to upgrade soon. We weren't using the Samsung-provided cable as it didn't come with one - we were using a Nokia one that my dh had which was the right size. It should have worked, but maybe that was the problem.
I only say that as my daughter has an MP3 player and we HAVE to use the cable that came with it to charge it; he tried another one the same size and it did nothing. But as soon as we swapped it for the proper one - it charged!
