My Sons Samsung Galaxy Ace Plus GT-S7500 was not charging tried multiple chargers and usb cables as my wife has same phone but nothing. Took it back to retailer in the weekend as its only 4 months old to see what they could do, paid the 60$ bond. Today (Monday) retailer rang my wife and told her the  charging port was corroded and they don't cover that (phone has never been wet). When I got home I googled "samsung corrosion" and found a few tech sites where this was a common problem, the best information about this problem was on this site http://forums.androidcentral.com/sprint-galaxy-s-ii-epic-4g-touch/152858-corrosion-charging-port.html .Thought this would be the best place to tell me what my best course of action would be push for repair, replacement, contact samsung? Or curse the gods and buy a better product?
