My grand daughter's 7036 won't charge. The charger plug seems a little loose and when I plug it in and press the power button it does not show charging. I checked the charger on my grand son's 7036, so I think it must be the connection on the 7036 power port. I have seen several complaints on this but would like to know if anyone has tried to repair theirs? It is under warranty and I can send it back along with $15 for return, except I have rooted it and can't unroot it. Not sure if they will check that. Any suggestions?
