Yes- I went to the TMobile store and used their fast charger and cord, and it still didn't work. Next, I called tech support– they suggested I clear the cache (didn't work) turn on fast charge in settings (was already on) and finally, do a factory reset, which also didn't work. My phone is relatively new and still under warranty, however, I dropped it a few months back and cracked the screen. It's not noticeable unless you have it in the sun, so I never bothered to fix it. I was told that my warranty is void because of the cracked screen. I can get a new screen via an authorized Samsung dealer and the warranty will be re-instated, but they don't have any local, so it will have to be sent out. I cannot be without my phone for the length of time it would take to fix it. If the screen wasn't cracked, I could replace it at the T Mobile store, but since it's cracked, I can't.
