It's difficult to suggest if aftermarket cables will work, and in what capacity or with what features. Some cables allow you to transfer, others allow you to both transfer and charge the phone.
I can't advise, since there are so many options on auction sites, and I risk injecting myself into a sales transaction. There are options on Samsungparts.com to purchase genuine cables, and that's what I'd recommend.
months ago I had a Samsung Gravity2, and an accessory I had for it was a combination wall charger/ USB cable. when I plugged the USB cable into my PC, a program came up called "PC Studio."
when the phone got ruined I got rid of the cable, & recently purchased a Samsung Strive. as I really can't afford to buy another similar accessory through retail, can someone tell me if low-cost cables like I see on ebay would work? all the ones I've seen are just USB cables without wall chargers, but some also say they require additional software. all I want to do is be able to get pics from my new phone to my PC as cheaply and easily as possible.
