I've had a lot of problems with my Samsung Charge - however, NOW it is not charging. I have used 4 different chargers now so it is not the charger. Should I get battery replaced as I have read in other posts or just turn in for replacement? I wiggle the cord and sometimes it will start charging again, but then the screen goes blank and I can't tell if it is charging so I turn on the screen and sure enough it has stopped again. BTW - I have also had problems with random restarting on my phone, shutting off while taking a picture, touch screen just stops working and the phone gets pretty hot sometimes. All I guess I can live with but if I can't charge it, that doesn't work. HELP!
